Enhanced Th1 and dampened Th2 responses synergize to inhibit acute granulomatous and fibrotic responses in murine schistosomiasis mansoni. (1/5330)

In murine schistosomiasis mansoni, CD4(+) Th1 and Th2 cells participate in the ovum-induced granulomatous inflammation. Previous studies showed that the interleukin-12 (IL-12)-induced Th1 response strongly suppressed the Th2-cell-mediated pulmonary granuloma development in naive or primed mice. However, liver granulomas were only moderately suppressed in egg-vaccinated, recombinant IL-12 (rIL-12)-treated infected mice. The present study shows that repeated rIL-12 injections given during early granuloma development at 5 to 7 weeks after infection prolonged the Th1 phase and resulted in gamma interferon-mediated suppression of liver granulomas. The timing is crucial: if given at 6 to 8 weeks, during the Th2-dominated phase of florid granuloma growth, the treatment is ineffective. Daily injections of rIL-12 given between 5 and 7.5 weeks during the period of granuloma growth achieved a somewhat-stronger diminution in granuloma growth with less deposition of collagen but caused 60% mortality and liver pathology. In contrast, combined treatment with rIL-12 and anti-IL-4-anti-IL-10 monoclonal antibody (MAb) injections given during the Th2 phase strongly inhibited liver granuloma growth without mortality. The diminished inflammatory response was accompanied by less deposition of collagen in the liver. Moreover, neutralization of endogenous IL-12 by anti-IL-12 MAbs effectively decreased the early Th1 phase (between 5 and 6 weeks after infection) but not the developing Th2 phase (5 to 7 weeks) of granuloma development. These studies indicate that the granulomatous response in infected mice can be manipulated by utilizing the Th1-Th2-subset antagonism with potential salutary results in the amelioration of fibrous pathology.  (+info)

Elevated carboxy terminal cross linked telopeptide of type I collagen in alcoholic cirrhosis: relation to liver and kidney function and bone metabolism. (2/5330)

BACKGROUND: The carboxy terminal cross linked telopeptide of type I collagen (ICTP) has been put forward as a marker of bone resorption. Patients with alcoholic liver disease may have osteodystrophy. AIMS: To assess circulating and regional concentrations of ICTP in relation to liver dysfunction, bone metabolism, and fibrosis. METHODS: In 15 patients with alcoholic cirrhosis and 20 controls, hepatic venous, renal venous, and femoral arterial concentrations of ICTP, and bone mass and metabolism were measured. RESULTS: Circulating ICTP was higher in patients with cirrhosis than in controls. No overall significant hepatic disposal or production was found in the patient or control groups but slightly increased production was found in a subset of patients with advanced disease. Significant renal extraction was observed in the controls, whereas only a borderline significant extraction was observed in the patients. Measurements of bone mass and metabolism indicated only a mild degree of osteodystrophy in the patients with cirrhosis. ICTP correlated significantly in the cirrhotic patients with hepatic and renal dysfunction and fibrosis, but not with measurements of bone mass or metabolism. CONCLUSIONS: ICTP is highly elevated in patients with cirrhosis, with no detectable hepatic net production or disposal. No relation between ICTP and markers of bone metabolism was identified, but there was a relation to indicators of liver dysfunction and fibrosis. As the cirrhotic patients conceivably only had mild osteopenia, the elevated ICTP in cirrhosis may therefore primarily reflect liver failure and hepatic fibrosis.  (+info)

3D MRI of the membranous labyrinth. An age related comparison of MR findings in patients with labyrinthine fibrosis and in persons without inner ear symptoms. (3/5330)

PURPOSE: We compared MRI of the membranous labyrinth in patients with chronic non-neoplastic inner ear disease and MR signs of labyrinthine fibrosis and controls depending on their age, in order to establish whether there were any MR differences regarding patient age groups, control age groups and between the patients and controls themselves. MATERIALS AND METHODS: Clinical ENT examinations as well as a T2* weighted 3D CISS (Constructive Interference in Steady State) sequence with a slice thickness of 0.7 mm were performed. Our collective was subdivided as follows: 0-19 years (10 controls, 3 patients with chronic non-neoplastic inner ear disease), 20-49 years (55 controls, 8 patients), 50 years and older (40 controls, 22 patients). Detectability of labyrinthine structures (e.g. cochlea, vestibule, semicircular canals) and filling defects were evaluated. RESULTS: In the 3 age-groups of the control collective no significant differences were observed in the membranous labyrinth. However differences concerning labyrinthine detectability emerged between controls and patients in both the 20-49 years and 50 years and older age groups. In the patient collective the 3 age groups showed no significant discrepancy in the mean number of lesions. CONCLUSION: Filling defects of the membranous labyrinth on 3D CISS MR images are pathological even in older persons. We would therefore recommend high resolution T2* weighted MRI in the case of suspected labyrinthine fibrosis.  (+info)

Ultramicroscopic structures of the leptomeninx of mice with communicating hydrocephalus induced by human recombinant transforming growth factor-beta 1. (4/5330)

An experimental model of communicating hydrocephalus was developed based on intrathecal injection of human recombinant transforming growth factor-beta 1 (hrTGF-beta 1) in the mouse. To clarify the mechanism of this hydrocephalus model, the ultrastructure of the leptomeninx in the process of ventricular dilation was examined in C57/BL6 mice injected intrathecally with 60 ng of hrTGF-beta 1. The leptomeninx was examined at various periods after injection by light and electron microscopy. Immunostaining for fibroblasts and macrophages was also performed. Leptomeninx within a week after injection showed that the thin cytoplasmic processes of leptomeningeal cells formed a laminated structure with a meshwork, which was almost the same as the controls. In the second week, many cells with a round nucleus appeared in the leptomeninx. Immunohistochemically, these cells were positive for anti-fibroblast antibody and negative for anti-Mac-1 and anti-macrophage BM-8 antibodies. Three weeks later, the laminated structure was disrupted and abundant deposition of collagen fibers was found in the inter-cellular space of the leptomeninx. Such inter-meningeal fibrosis would disturb cerebrospinal fluid flow in the mouse leptomeninx and cause slowly progressive ventricular dilation.  (+info)

Irradiation induces upregulation of CD31 in human endothelial cells. (5/5330)

Radiation-induced vascular injury is believed to be a major factor contributing to parenchymal atrophy, fibrosis and necrosis in normal tissue after radiotherapy. In this study irradiation of human umbilical vein endothelial cells (HUVECs) significantly increased adherence of U-937 cells in a time-dependent manner. Given the potential multifunctional role of CD31 in the vasculature we have examined the possible effects of irradiation on levels of CD31 expression in HUVECs. Irradiation upregulated CD31 expression on HUVECs, independently of initial plating density and radiation-induced changes such as cell number, cell cycle stage, or cell size. CD31 mRNA levels were raised in irradiated HUVECs relative to controls. Both CD31 mRNA and surface protein showed similar changes, suggesting that the increase in mRNA in irradiated HUVECs is responsible for the elevation in cell surface protein. A semi-quantitative study of tissue specimens from patients who had received radiotherapy indicated that CD31 staining in the blood vessels from irradiated tissues was increased compared with controls. Endothelial CD31 is important in the transmigration of leukocytes. We have demonstrated that the incorporation of monoclonal antibody to CD31 significantly inhibited the transmigration of human peripheral blood leukocytes through a monolayer of irradiated HUVECs. Taken together these data strongly suggest that irradiation induces a marked increase in CD31 expression on endothelial cells as part of a general response to irradiation. Its upregulation may play an important role in the development of radiation-induced normal tissue damage and thus is a possible target for therapeutic intervention.  (+info)

Pancreatic stellate cells are activated by proinflammatory cytokines: implications for pancreatic fibrogenesis. (6/5330)

BACKGROUND: The pathogenesis of pancreatic fibrosis is unknown. In the liver, stellate cells play a major role in fibrogenesis by synthesising increased amounts of collagen and other extracellular matrix (ECM) proteins when activated by profibrogenic mediators such as cytokines and oxidant stress. AIMS: To determine whether cultured rat pancreatic stellate cells produce collagen and other ECM proteins, and exhibit signs of activation when exposed to the cytokines platelet derived growth factor (PDGF) or transforming growth factor beta (TGF-beta). METHODS: Cultured pancreatic stellate cells were immunostained for the ECM proteins procollagen III, collagen I, laminin, and fibronectin using specific polyclonal antibodies. For cytokine studies, triplicate wells of cells were incubated with increasing concentrations of PDGF or TGF-beta. RESULTS: Cultured pancreatic stellate cells stained strongly positive for all ECM proteins tested. Incubation of cells with 1, 5, and 10 ng/ml PDGF led to a significant dose related increase in cell counts as well as in the incorporation of 3H-thymidine into DNA. Stellate cells exposed to 0.25, 0.5, and 1 ng/ml TGF-beta showed a dose dependent increase in alpha smooth muscle actin expression and increased collagen synthesis. In addition, TGF-beta increased the expression of PDGF receptors on stellate cells. CONCLUSIONS: Pancreatic stellate cells produce collagen and other extracellular matrix proteins, and respond to the cytokines PDGF and TGF-beta by increased proliferation and increased collagen synthesis. These results suggest an important role for stellate cells in pancreatic fibrogenesis.  (+info)

Cyclosporin exerts a direct fibrogenic effect on human tubulointerstitial cells: roles of insulin-like growth factor I, transforming growth factor beta1, and platelet-derived growth factor. (7/5330)

To assess the direct fibrogenic effects of cyclosporin A (CyA) on the human tubulointerstitium, primary cultures of human renal proximal tubule cells (PTC) and renal cortical fibroblasts (CF) were incubated for 24 h with various concentrations of CyA. Cytotoxicity was confirmed in both cell populations by dose-dependent inhibition of thymidine incorporation, viability, and PTC apical sodium-hydrogen exchange activity (ethylisopropylamiloride-sensitive apical 22Na+ uptake). Compared with controls, both 500 and 1000 ng/ml CyA significantly stimulated CF collagen synthesis (proline incorporation 4.6 +/- 0.4, 6.5 +/- 0.8, and 7.1 +/- 1.0%, respectively; p <.05) and inhibited matrix metalloproteinase-2 (100%, 85.7 +/- 10.0%, and 38.8 +/- 9.2%) and matrix metalloproteinase-9 activity (100%, 110.6 +/- 19.0%, and 49.9 +/- 12.8%). CyA did not affect CF secretion of transforming growth factor beta1, but markedly stimulated insulin-like growth factor-I (IGF-I) secretion and inhibited secretion of both IGF-I binding protein-(IGFBP)-3 and IGFBP-2. CyA-induced CF collagen synthesis was abrogated by 5 microgram/ml anti-IGF-I receptor antibody, but not by 5 microgram/ml murine nonimmune globulin. Increasing concentrations of CyA progressively augmented PTC secretion of the fibrogenic cytokines transforming growth factor-beta1 and platelet-derived growth factor. These results indicate that clinically relevant concentrations of CyA are directly toxic to PTC and CF, irrespective of hemodynamic effects, and promote interstitial fibrosis by inhibiting matrix degradation and stimulating cortical fibroblast collagen synthesis via induction of autocrine IGF-I action. The latter effect may be further accentuated by the ability of CyA to augment secretion of transforming growth factor beta1 and platelet-derived growth factor by PTCs.  (+info)

Prognostic significance of bone marrow biopsy in essential thrombocythemia. (8/5330)

BACKGROUND AND OBJECTIVE: The diagnostic and prognostic value of bone marrow biopsy (BMB) has been widely investigated in patients with chronic myeloproliferative disorders (CMPD). The present study is based on a review of the results of routine BMBs taken from 93 essential thrombocythemia (ET) patients at the time of diagnosis. DESIGN AND METHODS: The common BMB histologic parameters and clinico-hematologic variables were considered for diagnostic and prognostic purposes. Clinico-pathologic correlations were looked for univariately. Moreover, the diagnostic significance of the histologic findings was tested by means of cluster analysis. Overall survival and event-free survival were considered as prognostic endpoints. RESULTS: There were no correlations between the clinic and pathologic findings, and none of the histologic and clinical parameters was predictive of survival or the occurrence of major clinical events. Cluster analysis of the BMB findings revealed two distinct morphologic patterns: one was clearly myeloproliferative; the other had somewhat dysplastic features. The event-free and overall survival rates in the latter group were significantly worse (p = 0.0377 and p = 0.0162 respectively), with major ischemic events accounting for most of the difference in event-free survival. INTERPRETATION AND CONCLUSIONS: These results have no clearcut counterpart in the literature, but we feel that dysplastic BMB findings could be included in the definition of ET prognostic scores in order to allow therapeutic strategies to be adapted to the level of risk.  (+info)

The present PhD proposes a rigorous evaluation and quantification of pediatric liver allograft fibrosis in 595 liver biopsies of 139 patients from 6 months to 10 years following liver transplantation, analyzing the influence of clinical variables and the immunosuppression on fibrosis progression, as well as the relevance of activated Hepatic Stellate cells (HSCs) in predicting allograft fibrosis development. A novel fibrosis scoring system, the Liver Allograft Fibrosis Score, was designed and validated specifically for allograft fibrosis assessment, categorizing separately sinusoidal, centrilobular and portal fibrosis. Progressive fibrosis was found in 74% of the liver biopsies reviewed. Clinical factors were identified to promote fibrosis in a specific area of the liver parenchyma. The steroid therapy did not contribute to reduce fibrosis. Finally, the high proportion of activated-HSCs found in this population was useful as a predictor of long-term allograft fibrosis development.. [fre] Cette ...
Liver organ fibrosis is the final stage of liver diseases that lead to liver failure and malignancy. gene manifestation was inhibited in the advanced stage of liver fibrosis while transient but prominent MMP13 gene manifestation occurs during the early stage of recovery from experimental rat liver organ fibrosis. It is therefore acceptable to consider that upregulation of MMP13 gene appearance can lead to a consequent upsurge in collagenase activity in fibrotic livers and provide a procedure for antifibrotic therapy in preventing liver organ fibrosis. Since comprehensive regression from advanced cirrhosis is normally both doubtful and controversial it really is even more feasible to build up a secure and efficient method of preventing the development of fibrosis in liver organ disease. In regards to towards the transfer from the MMP gene in to the liver organ youll be able to selectively inject nude DNA in to the liver organ via either the portal vein or the hepatic artery. Gene delivery ...
Background: Cardiac fibrosis contributes to heart failure progression following myocardial infarction (MI) and chronic kidney disease (uremic cardiomyopathy). We examined the effect of the anti-fibrotic agent, tranilast, on cardiac fibrosis in both heart and kidney failure.. Methods: MI was induced by coronary artery ligation in Sprague Dawley (SD) rats, and animals randomized to receive tranilast (300mg/kg/day, p.o.) or vehicle for 28 days. Renal failure was induced by 5/6 nephrectomy (STNx) and animals randomized to receive tranilast (300mg/kg/day, p.o.) or vehicle for 12 weeks. Myocardial tissues were harvested for histological analysis. To determine direct effects of tranilast, cardiac fibrosis independent of any hemodynamic influence, neonatal cardiac fibroblasts (NCF) were stimulated with TGFβ1 in the presence and absence of tranilast and examined for proline incorporation, profibrotic gene and phospho-Smad2 protein expression.. Results: Tranilast treatment in MI animals attenuated the ...
TY - JOUR. T1 - Novel anti-fibrotic therapies. AU - McVicker, Benita L.. AU - Bennett, Robert G.. PY - 2017/5/31. Y1 - 2017/5/31. N2 - Fibrosis is a major player in cardiovascular disease, both as a contributor to the development of disease, as well as a post-injury response that drives progression. Despite the identification of many mechanisms responsible for cardiovascular fibrosis, to date no treatments have emerged that have effectively reduced the excess deposition of extracellular matrix associated with fibrotic conditions. Novel treatments have recently been identified that hold promise as potential therapeutic agents for cardiovascular diseases associated with fibrosis, as well as other fibrotic conditions. The purpose of this review is to provide an overview of emerging antifibrotic agents that have shown encouraging results in preclinical or early clinical studies, but have not yet been approved for use in human disease. One of these agents is bone morphogenetic protein-7 (BMP7), which ...

GenengNews.com Researchers at the University of Birmingham in the U.K. say they have shown that a novel low molecular weight dextran-sulphate, ILB®, could play a key role in treating open-angle glaucoma (OAG), a neurodegenerative disease that affects over 70 million people worldwide and causes irreversible blindness. OAG develops slowly over many years. Fibrosis within the eye’s main fluid drainage site can lead to increased intraocular pressure (IOP), resulting in damage to the optic nerve. The team’s study “ILB resolves inflammatory scarring and promotes functional tissue repair,” reported in npj Regenerative Medicine, has shown that that ILB can normalize matrix deposition inside the eye and lower IOP in a preclinical model used to mimic these aspects of human glaucoma, paving the way for new anti-fibrotic therapies to be developed for the disease. OAG is a complex disease and it has proved difficult to develop effective therapeutics to target the biochemical pathways
Background: Prognostic value of myocardial fibrosis in patients with non-ischemic idiopathic cardiomyopathy (NICM) is not well-defined. We sought to assess the association of focal and diffuse myocardial fibrosis to left ventricular reversed remodeling.. Methods: Patients with NICM who underwent cardiac MRI and baseline and subsequent follow-up echocardiographic were included in the study. Post-contrast T1 times were measured using Look-Locker gradient echo, and was adjusted for renal function, body size, gadolinium dose and delayed time after Gadolinium injection. Patients were followed over a median time of 29 months (20,37) to evaluate changes of left ventricular end-systolic volume index (LVESVi) over time. Linear Mixed Model was used to assess the relationship between the LVESVi during follow-up,T1 value, and delayed hyperenhancement (DHE).. Results: A total of 103 patients (mean age 51±15 years, 62% male) were included in the analysis. Mean LVEF 32±10%, LVESVi 62±39 ml/m2, and T1 time ...
Cardiac fibrosis as a result of excessive extracellular matrix deposition leads to stiffening of the heart, which can eventually lead to heart failure. An important event in cardiac fibrosis is the transformation of fibroblasts into myofibroblasts, which secrete large amounts of extracellular matrix proteins. While the function of protein-coding genes in myofibroblast activation and fibrosis has been a topic of investigation for a long time, it has become clear that non-coding RNAs also play key roles in cardiac fibrosis. This review discusses the involvement of microRNAs and lncRNAs in cardiac fibrosis and summarizes the issues related to translating these findings into real life therapies. ...
Fibrosis contributes to the development of many diseases and many target molecules are involved in fibrosis. Currently, the majority of fibrosis treatment strategies are limited to specific diseases or organs. However, accumulating evidence demonstrates great similarities among fibroproliferative diseases, and more and more drugs are proved to be effective anti-fibrotic therapies across different diseases and organs. Here we comprehensively review the current knowledge on the pathological mechanisms of fibrosis, and divide factors mediating fibrosis progression into extracellular and intracellular groups. Furthermore, we systematically summarize both single and multiple component drugs that target fibrosis. Future directions of fibrosis drug discovery are also proposed.
Renal fibrosis is a serious clinical problem forming the utmost cause of need for renal replacement therapy. No adequate preventive or curative therapy is available that can be clinically used to specifically target renal fibrosis. The search for new efficacious treatment strategies is therefore warranted. Although in vitro models using homogeneous cell populations have contributed to the understanding of the pathogenetic mechanisms involved in renal fibrosis, these models poorly mimic the complex in vivo milieu. Therefore, here we evaluated a precision-cut kidney slice (PCKS) model as a new, multicellular ex vivo model to study development of fibrosis and the prevention thereof using anti-fibrotic compounds.. Precision-cut slices (200-300 µm thickness) were prepared from healthy C57BL/6 mouse kidneys using a Krumdieck tissue slicer. To induce changes mimicking the fibrotic process, slices were incubated with TGFβ1 (5 ng/ml) for 48 hours in the presence or absence of the anti-fibrotic cytokine ...
Results Nintedanib dose-dependently reduced platelet-derived growth factor-induced and transforming growth factor-β-induced proliferation and migration as well as myofibroblast differentiation and collagen release of dermal fibroblasts from patients with and healthy individuals. Nintedanib also inhibited the endogenous activation of SSc fibroblasts. Nintedanib prevented bleomycin-induced skin fibrosis in a dose-dependent manner and was also effective in the treatment of established fibrosis. Moreover, treatment with nintedanib ameliorated fibrosis in the chronic graft-versus-host disease model and in tight-skin-1 mice in well-tolerated doses. ...
Both groups survived long-term (,100 days). The allogeneic grafts were infiltrated by significantly increased numbers of CD4+ (P ,0.0001), CD8+ (P ,0.0001), and CD11b+ cells (P = 0.0065) by day 100. Furthermore, elevated IL-13 levels (P = 0.0003) and numbers of infiltrating IL-13+ cells (P = 0.0037), together with an expression of IL-13Rα2, were detected only within allografts. The expression of IL-13 and IL-13Rα2 resulted in significantly increased TGF-β1 levels (P ,0.0001), higher numbers of CD11bhighGr1intermediateTGF-β1+ cells, and elevated cardiac collagen deposition (P = 0.0094). The allograft fibrosis found in these experiments was accompanied by upregulation of multiple profibrotic genes, which was confirmed by immunohistochemical stainings of allograft tissue. Blockage of the IL-13/TGF-β1 interaction by IL-13Rα2 siRNA led to lower numbers of CD11bhighGr1intermediateTGF-β1+, CD4+, CD8+, and CD11b+ cells, and prevented collagen deposition (P = 0.0018) within these allografts ...
Renal fibrosis is a main cause of end-stage renal disease. Clinically, there is no beneficial treatment that can effectively reverse the progressive loss of renal function. We recently synthesized a novel proteolysis-resistant cyclic helix B peptide (CHBP) that exhibits promising renoprotective effects. In this study, we evaluated the effect of CHBP on renal fibrosis in an in vivo ischemia reperfusion injury (IRI) model and in vitro TGF-β-stimulated tubular epithelial cells (TCMK-1 and HK-2) model. In the IRI in vivo model, mice were randomly divided into sham (sham operation), IR and IR + CHBP groups (n = 6). CHBP (8 nmol/kg) was administered intraperitoneally at the onset of reperfusion, and renal fibrosis was evaluated at 12 weeks post-reperfusion. Our results showed that CHBP markedly attenuated the IRI-induced deposition of collagen I and vimentin. In the in vitro model, CHBP reversed the TGF-β-induced down-regulation of E-cadherin and up-regulation of α-SMA and vimentin. Furthermore, CHBP
Fibrosis is defined by the deposition of pathological fibrillar collagen, inflammatory cells, loss of capillaries, and dedifferentiation of epithelial cells. Fibrosis occurs as a part of normal wound healing. However, excessive or dysregulated fibrosis can lead to severe organ dysfunction and is a feature of a variety of diseases. Due to its insidious onset, fibrosis tends to go undetected in its early stages. This is in part why these diseases remain so poorly understood. Animal models have provided a means to examine these early stages and to isolate and understand the effect of perturbations in signaling pathways, chemokines, and cytokines. Here, we summarize recent progress in the understanding of the molecular pathogenesis of fibrosis, both its initiation and its maintenance phases, from animal models of fibrosis in the skin and liver. Due to these organs properties, modeling fibrosis in them poses unique challenges. Elegant solutions have therefore been developed for modeling fibrosis in

Tubulointerstitial fibrosis invariably accompanies the course of chronic renal failure towards end-stage renal disease. Tubular epithelial cells, the predominant cell type in the tubulointerstitium, are increasingly being recognized for playing a dominant role as mediators of renal fibrogenesis. Tub …
Fibrosis occurs when transforming growth factor-β (TGF-β) signaling is not attenuated after wound healing and fibroblasts remain activated, resulting in tissue scarring. The mechanisms that turn off TGF-β signaling after wound healing and inhibit this pathway in general are not well-understood. Palumbo-Zerr et al. noted that the abundance of the orphan receptor NR4A1 (nuclear receptor 4A1) was increased at the mRNA and protein levels in the fibrotic skin of patients with systemic sclerosis and in the skin of mice overexpressing a constitutively active TGF-β receptor type I (TBRI), which are a model for fibrosis. TGF-β stimulated the increased expression of NR4A1 through a complex containing the transcriptional effectors SMAD3, SMAD4, and SP1. Global Nr4a1 deficiency enhanced the expression of TGF-β target genes and fibrosis in mice overexpressing TBRI, as well as in other mouse models of fibrosis, including pulmonary fibrosis induced by bleomycin. Nr4a1-/- fibroblasts deposited more ...

Objective: To analyze the CT imaging results of patients with COVID-19 who previously received several follow-up visits and to explain the changes in pulmonary inflammation. Methods: Cases of 15 patients with COVID-19 were retrospectively analyzed: their epidemiology, clinical history, laboratory tests, and multiple CT chest scans obtained during the disease period were studied. Results: The CT scans of the 15 patients showed different results. Four patients had no abnormal findings in their chest CT scans. The first scan of 1 patient revealed right lower lobe inflammation, while the lesion had been completely absorbed in follow-up. Two patients showed bilateral pulmonary inflammation in the first scan which had been absorbed by follow-up but the last examination showed extensive fibrosis. Two patients had no abnormalities in their first CT scans, while pulmonary inflammation was found in the second scan and this had not been completely absorbed by the last follow-up. One patient had pulmonary ...
One of the most difficult problems to tackle is the development of fibrosis (scarring) which is a direct consequence of the kidneys limited capacity to regenerate after injury. Such fibrosis can develop into a life-threatening condition. At present we may be able to halt the progression of renal scarring, but thats all. Early detection of CKD would allow improved disease management.. One thing to remember is that the aetiology of CKD is diverse. It includes immunological, mechanical, metabolic and toxic origins amongst others. To complicate the matter further it will affect three functional compartments of the kidney: the vasculature, glomerulus and tubulointerstitium . Therefore, it is extremely challenging to choose the optimal therapy. At present, renal biopsy offers one of the best methods to test for the presence of fibrosis but it requires surgical intervention, is painful, and it is very costly. A non-invasive method to detect the early incidence of such fibrosis would be ...

Systemic sclerosis (SSc) is a connective tissue disorder characterised by the development of skin fibrosis. Our current understanding of the disease pathogenesis is incomplete and the study of SSc is hindered, at least partially, by a lack of animal models that fully replicate the complex state of human disease. Murine model of bleomycin-induced dermal fibrosis encapsulates important events that take place early in the disease course. To characterise the optimum in vivo parameters required for the successful induction of dermal fibrosis we subjected three commonly used mouse strains to repeated subcutaneous bleomycin injections. We aimed to identify the effects of genetic background and gender on the severity of skin fibrosis. We used male and female Balb/C, C57BL/6, and DBA/2 strains and assessed their susceptibility to bleomycin-induced fibrosis by measuring dermal thickness, hydroxyproline/collagen content and number of resident myofibroblasts, all of which are important indicators of the severity of
Adipose tissue fibrosis development blocks adipocyte hypertrophy and favors ectopic lipid accumulation. Here, we show that adipose tissue fibrosis is associated with obesity and insulin resistance in humans and mice. Kinetic studies in C3H mice fed a high-fat diet show activation of macrophages and progression of fibrosis along with adipocyte metabolic dysfunction and death. Adipose tissue fibrosis is attenuated by macrophage depletion. Impairment of Toll-like receptor 4 signaling protects mice from obesity-induced fibrosis. The presence of a functional Toll-like receptor 4 on adipose tissue hematopoietic cells is necessary for the initiation of adipose tissue fibrosis. Continuous low-dose infusion of the Toll-like receptor 4 ligand, lipopolysaccharide, promotes adipose tissue fibrosis. Ex vivo, lipopolysaccharide-mediated induction of fibrosis is prevented by antibodies against the profibrotic factor TGFβ1. Together, these results indicate that obesity and endotoxemia favor the development of adipose
Fibroproliferative disorders such as idiopathic pulmonary fibrosis and systemic sclerosis have no effective therapies and result in significant morbidity and mortality due to progressive organ fibrosis. We examined the effect of peptides derived from endostatin on existing fibrosis and fibrosis triggered by two potent mediators, transforming growth factor-β (TGF-β) and bleomycin, in human and mouse tissues in vitro, ex vivo, and in vivo. We identified one peptide, E4, with potent antifibrotic activity. E4 prevented TGF-β-induced dermal fibrosis in vivo in a mouse model, ex vivo in human skin, and in bleomycin-induced dermal and pulmonary fibrosis in vivo, demonstrating that E4 exerts potent antifibrotic effects. In addition, E4 significantly reduced existing fibrosis in these preclinical models. E4 amelioration of fibrosis was accompanied by reduced cell apoptosis and lower levels of lysyl oxidase, an enzyme that cross-links collagen, and Egr-1 (early growth response gene-1), a transcription ...
Interstitial fibrosis can be an inevitable outcome of all kinds of progressive chronic kidney disease (CKD). suppressed the immunoreactivity of mTOR signaling, which decreased the inflammatory responses and ECM accumulation in the obstructed kidneys. Isolated macrophages from rapamycin-treated obstructed kidneys presented less inflammatory activity than vehicle groups. In vitro study confirmed that rapamycin significantly inhibited the fibrogenic activation of cultured fibroblasts (NIH3T3 cells), which was induced by the stimulation of TGF-1. Further experiment revealed that rapamycin did not directly inhibit the fibrogenesis of HK2 cells with aristolochic acid treatment. Our findings clarified that rapamycin can ameliorate kidney fibrosis by blocking the mTOR signaling in interstitial macrophages and myofibroblasts. Introduction Tubulointerstitial fibrosis is the final common pathway of a wide variety of chronic progressive kidney diseases. Intense studies have focused on the molecular and ...

N2 - BACKGROUND: Abnormal P-terminal force in lead V1 (PTFV1) is associated with an increased risk of heart failure, stroke, atrial fibrillation, and death. OBJECTIVE: Our goal was to explore associations of left ventricular (LV) diffuse fibrosis with left atrial (LA) function and electrocardiographic (ECG) measures of LA electrical activity. METHODS: Patients without atrial fibrillation (n = 91; mean age 59.5 years; 61.5% men; 65.9% white) with structural heart disease (spatial QRS-T angle ≥105° and/or Selvester QRS score ≥5 on ECG) but LV ...
Background: Using cardiovascular magnetic resonance imaging (CMR), it is possible to detect diffuse fibrosis of the left ventricle (LV) in patients with atrial fibrillation (AF), which may be independently associated with recurrence of AF after ablation. By conducting CMR, clinical, electrophysiology and biomarker assessment we planned to investigate LV myocardial fibrosis in patients undergoing AF ablation. Methods: LV fibrosis was assessed by T1 mapping in 31 patients undergoing percutaneous ablation for AF. Galectin-3, coronary sinus type I collagen C terminal telopeptide (ICTP), and type III procollagen N terminal peptide were measured with ELISA. Comparison was made between groups above and below the median for LV extracellular volume fraction (ECV), followed by regression analysis. Results: On linear regression analysis LV ECV had significant associations with invasive left atrial pressure (Beta 0.49, P = 0.008) and coronary sinus ICTP (Beta 0.75, P , 0.001), which remained significant on ...
Renal fibrosis is characterized by activation and proliferation of fibroblasts, which continually produce and deposit ECM proteins, leading to progressive fibrosis. Herein we demonstrate that GSK3β is expressed in myofibroblasts, and GSK3β expression and activity are increased in mouse kidneys following I/R and in cultured fibroblasts following TGF-β1 treatment. Pharmacological inhibition of GSK3 using TDZD significantly reduced pro-inflammatory and pro-fibrotic cytokines, macrophage infiltration and ECM deposition, thereby reducing fibrosis. GSK3 inhibition reduced the myofibroblast population in vivo and fibroblast-to-myofibroblast differentiation in vitro by a TGF-β-SMAD signaling-dependent mechanism. Thus, GSK3β plays a pro-fibrotic role in the kidney following I/R, and its inhibition, even after the injury has occurred, could prevent the future development of fibrosis.. GSK3β is expressed in proximal tubules (Nørregaard et al., 2015), and increased GSK3β has been detected in renal ...
In the pathogenesis of renal fibrosis, oxidative stress (OS) enhances the production of reactive oxygen species (ROS) leading to sustained cell growth, inflammation, excessive tissue remodelling and accumulation, which results in the development and acceleration of renal damage. In our previous work (128) we established protein DJ-1 (PARK7) as an important ROS scavenger and key player in renal cell response to OS. In the present study we investigated the impact of profibrogenic agonists on DJ-1 and shed light on the role of this protein in renal fibrosis. Treatment of renal fibroblasts and epithelial cells with the profibrogenic agonist ANG II or PDGF resulted in a significant up-regulation of DJ-1 expression parallel to an increase in the expression of fibrosis markers. Monitoring of DJ-1 expression in kidney extract and tissue sections from renal fibrosis mice model (Col4a3-deficient) revealed a disease grad dependent regulation of the protein. Overexpression of DJ-1 prompted cell resistance ...
A total of 32 patients (36.4%) had hypertension, 21 (23.9%) with hyperlipidemia, 9 (10.2%) with diabetes, 6 (6.8%) patients had with a history of tobacco abuse and 10 (11.4%) with coronary artery disease. A total of 38 (43.2%) patients were on statin, 25 (28.4%) were on angiotensin converting enzyme inhibitor, 36 (40.9%) were on a beta-°©-blocker, 31 (35.2%) were on anticoagulant, and 13 (14.8%) were on antiarrhythmic medication. Subsequent follow-°©-up MRIs were performe on 32 (36%) patients that exhibited progression of atrial fibrosis.. Using univariate logistic regression models we were not able to identify significant predictors of fibrosis progression. The majority of patients (64%) did not reveal any significant changes from the initial quality and quantity of atrial fibrosis at 1 year MRI follow-up. ...
The objective of our study was to investigate the effect of Aliskiren, a renin inhibitor, on the deoxycorticosterone (DOCA) induced myocardial fibrosis in a rat model and its underlying mechanism. A total of 45 Sprague-Dawley (SD) rats underwent right nephrectomy and were randomly assigned into 3 groups: control group (CON group: silicone tube was embedded subcutaneously); DOCA treated group (DOC group: 200 mg of DOCA was subcutaneously administered); DOCA and Aliskiren (ALI) treated group (ALI group: 200 mg of DOCA and 50 mg/kg/d ALI were subcutaneously and intragastrically given, respectively). Treatment was done for 4 weeks. Sirius red staining was employed to detect the expression of myocardial collagen, and the myocardial collagen volume fraction (CVF) and perivascular collagen volume area (PVCA) were calculated. Radioimmunoassay was carried out to measure the renin activity (RA) and content of angiotensin II (Ang II) in the plasma and ventricle. Western blot assay was done to detect the ...

Liver fibrosis is the excessive accumulation of extracellular matrix proteins including collagen that occurs in most types of chronic liver diseases. Advanced liver fibrosis results in cirrhosis, liver failure, and portal hypertension and often requires liver transplantation. Our knowledge of the cellular and molecular mechanisms of liver fibrosis has greatly advanced. Activated hepatic stellate cells, portal fibroblasts, and myofibroblasts of bone marrow origin have been identified as major collagen-producing cells in the injured liver. These cells are activated by fibrogenic cytokines such as TGF-β1, angiotensin II, and leptin. Reversibility of advanced liver fibrosis in patients has been recently documented, which has stimulated researchers to develop antifibrotic drugs. Emerging antifibrotic therapies are aimed at inhibiting the accumulation of fibrogenic cells and/or preventing the deposition of extracellular matrix proteins. Although many therapeutic interventions are effective in ...
Cysteine-rich protein 61 (Cyr61) is a secreted matrix-associated protein that regulates a broad spectrum of biological and cellular activities. This study aimed to investigate the role of Cyr61 in progressive kidney fibrosis induced by unilateral ureteral obstruction (UUO) surgery in mice. The expression of Cyr61 transcripts and proteins in the obstructed kidneys were increased from day 1 and remained high until day 10 after surgery. Immunohistochemistry indicated that Cyr61 was expressed mainly in renal tubular epithelial cells. The upregulated Cyr61 in UUO kidneys was reduced in mice treated with pan-transforming growth factor-β (TGF-β) antibody. The role of TGF-β in tubular Cyr61 upregulation after obstructive kidney injury was further supported by experiments showing that TGF-β1 stimulated Cyr61 expression in cultured tubular epithelial cells. Notably, the upregulation of Cyr61 in UUO kidneys was followed by a marked increase in monocyte chemoattractant protein 1 (MCP-1) ...
Finding a gene for familial cardiac fibrosis (NHS grant 2000.130) Summary of results. A large multi-generation family with an autosomal dominantly inherited form of cardiac fibrosis with a highly malignant clinical outcome is presented and used to identify the gene causing this disease. We consider it a hereditary form of cardiac fibrosis since it was shown that the myocardial fibrosis in this family preceded the clinical and echocardiographic signs.. Twenty-four individuals from this family were clinically evaluated and 18 of them were used for a genome wide linkage analysis giving the highest LOD score (2.6) in the region of the lamin AC (LMNA) gene. Mutation analyses of this candidate gene failed to show a point mutation. Subsequent Southern blot and multiplex ligation-dependent probe amplification analyses, however, revealed a deletion of the start-codon containing exon. The up- and downstream flanking exons proved not to be deleted.. Furthermore, we demonstrate in-vitro that the deletion ...
The master cytokine TGF-β mediates tissue fibrosis associated with inflammation and tissue injury. TGF-β induces fibroblast activation and differentiation into myofibroblasts that secrete extracellular matrix proteins. Canonical TGF-β signaling mobilizes Smad2 and Smad3 transcription factors that control fibrosis by promoting gene expression. However, the importance of TGF-β-Smad2/3 signaling in fibroblast-mediated cardiac fibrosis has not been directly evaluated in vivo. Here, we examined pressure overload-induced cardiac fibrosis in fibroblast- and myofibroblast-specific inducible Cre-expressing mouse lines with selective deletion of the TGF-β receptors Tgfbr1/2, Smad2, or Smad3. Fibroblast-specific deletion of Tgfbr1/2 or Smad3, but not Smad2, markedly reduced the pressure overload-induced fibrotic response as well as fibrosis mediated by a heart-specific, latency-resistant TGF-β mutant transgene. Interestingly, cardiac fibroblast-specific deletion of Tgfbr1/2, but not Smad2/3, ...
2015 The Authors. Uncontrolled extracellular matrix (ECM) production by fibroblasts in response to injury contributes to fibrotic diseases, including idiopathic pulmonary fibrosis (IPF). Reactive oxygen species (ROS) generation is involved in the pathogenesis of IPF. Transforming growth factor-β1 (TGF-β1) stimulates the production of NADPH oxidase 4 (NOX4)-dependent ROS, promoting lung fibrosis (LF). Dysregulation of microRNAs (miRNAs) has been shown to contribute to LF. To identify miRNAs involved in redox regulation relevant for IPF, we performed arrays in human lung fibroblasts exposed to ROS. miR-9-5p was selected as the best candidate and we demonstrate its inhibitory effect on TGF-β receptor type II (TGFBR2) and NOX4 expression. Increased expression of miR-9-5p abrogates TGF-β1-dependent myofibroblast phenotypic transformation. In the mouse model of bleomycin-induced LF, miR-9-5p dramatically reduces fibrogenesis and inhibition of miR-9-5p and prevents its anti-fibrotic effect both in ...

The biology of heart failure is complex and diverse (2), posing challenges for developing efficacious therapies. All but one recent phase III heart failure trial failed to reduce mortality (3). Unlike oncology, we do not split heart failure into subtypes on the basis of disease pathways (4). We need a more targeted approach, not only for drug development, but also for drug response monitoring. Myocardial fibrosis is an attractive biomarker-fibrosis is already an established marker in the liver, kidneys, and lung-and likely a causal disease pathway mediating outcomes. Cardiac fibrosis can be measured on myocardial biopsy and tracks disease severity and outcome (5,6). But biopsy is invasive and impractical for routine clinical diagnosis and monitoring (7). Many of our current measurements are partial surrogates for fibrosis (e.g., imaging for cardiac remodeling, systolic and diastolic function), but more are needed, particularly circulating blood biomarkers. Cardiology quantifies only 2 myocardial ...
TY - JOUR. T1 - A DDX5 S480A polymorphism is associated with increased transcription of fibrogenic genes in hepatic stellate cells. AU - Guo, Jinsheng. AU - Hong, Feng. AU - Loke, Johnny. AU - Yea, Steven. AU - Lim, Chooi Ling. AU - Lee, Ursula. AU - Mann, Derek A.. AU - Walsh, Martin J.. AU - Sninsky, John J.. AU - Friedman, Scott L.. PY - 2010/2/19. Y1 - 2010/2/19. N2 - We recently identified a missense single nucleotide polymorphism (SNP) in DDX5 (rs1140409, p.S480A) that enhances the risk of developing cirrhosis. DDX5 is an ATP-dependent RNA helicase and transcriptional modulator. We hypothesized that the activity of DDX5 in regulating fibrogenic gene transcription in hepatic stellate cells (HSCs) is altered by the S480A SNP. To test this, we employed two approaches: 1) transient overexpression of DDX5 cDNA or siRNA knockdown of endogenous DDX5, with replacement by either DDX5 wild type (WT) or SNP cDNA, or 2) stable expression of exogenous DDX5 WT and SNP in HSC lines. WT DDX5 mRNA in HSCs ...
Renal tubular atrophy and interstitial fibrosis are common hallmarks of etiologically different progressive chronic kidney diseases (CKD) that eventually result in organ failure. Even though these pathological manifestations constitute a major public health problem, diagnostic tests, as well as therapeutic options, are currently limited. Members of the dickkopf (DKK) family, DKK1 and -2, have been associated with inhibition of Wnt signaling and organ fibrosis. Here, we identify DKK3 as a stress-induced, tubular epithelia-derived, secreted glycoprotein that mediates kidney fibrosis. Genetic as well as antibody-mediated abrogation of DKK3 led to reduced tubular atrophy and decreased interstitial matrix accumulation in two mouse models of renal fibrosis. This was facilitated by an amplified, antifibrogenic, inflammatory T cell response and diminished canonical Wnt/β-catenin signaling in stressed tubular epithelial cells. Moreover, in humans, urinary DKK3 levels specifically correlated with the ...
Results Females in all three groups had significantly increased septal myocardial ECV compared with males (0.29±0.03 vs 0.25±0.03, p,0.01). Septal myocardial ECV was higher in ALMS than hypertensive and controls (0.28±0.02 vs 0.25±0.03 vs 0.24±0.03, p,0.05). Three male older ALMS patients (mean 43±5 years vs 27±10 years) without a history of infantile CM had patchy diffuse LE in non-coronary artery territories with an increased ECV compared to remote normal myocardium (ECV 0.41±0.08 vs 0.27±0.03, p,0.05). MAPSE was reduced in patients with ALMS and hypertension compared to controls (13±2 cm/s vs 12±3 cm/s vs 17±2 cm/s, p,0.01. There were no differences in LV ejection fraction, LV mass or LA volumes. Septal myocardial ECV was negatively correlated with a MAPSE in patients with ALMS (r=−0.64, p,0.05). NT-BNP was not correlated with septal ECV but was increased in patients with LGE (median 178 pmol/l vs 44 pmol/l).. ...
The master cytokine TGF-β mediates tissue fibrosis associated with inflammation and tissue injury. TGF-β induces fibroblast activation and differentiation into myofibroblasts that secrete extracellular matrix proteins. Canonical TGF-β signaling mobilizes Smad2 and Smad3 transcription factors that control fibrosis by promoting gene expression. However, the importance of TGF-β-Smad2/3 signaling in fibroblast-mediated cardiac fibrosis has not been directly evaluated in vivo. Here, we examined pressure overload-induced cardiac fibrosis in fibroblast- and myofibroblast-specific inducible Cre-expressing mouse lines with selective deletion of the TGF-β receptors Tgfbr1/2, Smad2, or Smad3. Fibroblast-specific deletion of Tgfbr1/2 or Smad3, but not Smad2, markedly reduced the pressure overload-induced fibrotic response as well as fibrosis mediated by a heart-specific, latency-resistant TGF-β mutant transgene. Interestingly, cardiac fibroblast-specific deletion of Tgfbr1/2, but not Smad2/3, ...

Abstract. Tubulointerstitial renal fibrosis, characterized as a progressive detrimental connective tissue deposition on the kidney parenchyma, appears to be a harmful process leading inevitably to renal function deterioration, independently of the primary renal disease which causes the original kidney injury. Epithelial to Mesenchymal Transition (EMT) of tubular epithelial cells which are transformed to mesenchymal fibroblasts migrating to adjacent interstitial parenchyma constitutes the principal mechanism of renal fibrosis along with local and circulating cells. Proteinuria as well as hypoxia is included among the main mechanisms of EMT stimulation. TGFβ-1 through the SMAD pathway is considered as the main modulator regulating the EMT molecular mechanism, probably in cooperation with hypoxia inducible factors. Hepatocyte Growth Factor (HGF) and Bone Morphogenetic Factor-7 (BMF-7) are inhibitory to EMT molecules which could prevent in experimental and clinical level the catastrophic process of ...
A major pathophysiological component of cardiac remodeling during heart failure (HF), cardiac fibrosis has become a target for therapeutic intervention. Additionally, compelling evidence indicates a key role of cardiac fibrosis in myocardial malfunctioning during aging. Cardiac fibrosis is a complex phenomenon resulting from aberrant activation of various cell types and signaling pathways as a consequence of injury or damage to tissue. It develops over a time course that also depends upon the type of noxa activation of tissue-specific repair programs, resulting in the subsequent activation of proliferation and migration of fibroblasts from different myocardial locations to the injury site, where they synthesize extracellular matrix (ECM) (1,2).. Tissue repair through the synthesis of new ECM by fibroblasts is beneficial, particularly after myocardial infarction. However, prolonged activation of this process results in excess scar tissue formation, increased ECM deposition, and therefore, bad ...
Most pro-fibrogenic polypeptides are produced by infiltrating immune, inflammatory, mesenchymal and tissue-specific cells, thereby facilitating paracrine pro-fibrogenic effects that perpetuate inflammation-driven fibrosis (see below) (Figure 2, Figure 3) [12]. One of the most potent pro-fibrogenic cytokines in vivo is TGFβ. Three TGFβ isoforms have been described to date (TGFβ1, TGFβ2 and TGFβ3), all of which are initially generated as latent precursors [70]. When active TGFβ is liberated, it binds to a heterodimeric receptor complex consisting of one TGFβ type I receptor molecule, termed activin-linked kinase (ALK)5, and one TGFβ type II receptor. In the canonical TGFβ pathway in normal fibroblasts, ligand binding leads ALK5 to phosphorylate Smad2 and 3, which in turn bind to Smad4 to form a complex that is translocated to the nucleus, which activates transcription [71]. However, TGFβ has also been shown to signal via several additional pathways, including p38 mitogen-activated ...
Results TRB3 expression was increased in fibroblasts of patients with SSc and in murine models of SSc in a transforming growth factor-β (TGF-β)/Smad-dependent manner. Overexpression of TRB3 stimulated canonical TGF-β signalling and induced an activated phenotype in resting fibroblasts. In contrast, knockdown of TRB3 reduced the profibrotic effects of TGF-β and decreased the collagen synthesis. Moreover, siRNA-mediated knockdown of TRB3 exerted potent antifibrotic effects and ameliorated bleomycin as well as constitutively active TGF-β receptor I-induced fibrosis with reduced dermal thickening, decreased hydroxyproline content and impaired myofibroblast differentiation. ...

N2 - Animal models are a valuable tool in preclinical research. However, limited predictivity of human biological responses in the conventional models has stimulated the search for reliable preclinical tools that show translational robustness. Here, we used precision-cut kidney slices (PCKS) as a model of renal fibrosis and investigated its predictive capacity for screening the effects of anti-fibrotics. Murine and human PCKS were exposed to TGF beta or PDGF pathway inhibitors ...
Cystic fibrosis is an inherited chronic disease that affects the lungs and digestive system. A defective gene and its protein product cause the body to produce unusually thick, sticky mucus.. Cystic fibrosis Symptoms:. Clogs the lungs and leads to life-threatening lung infections;. Obstructs the pancreas and stops natural enzymes from helping the body break down and absorb food.. Now researchers are discovering that cystic fibrosis can be found among adults also and it is more complicated than what the doctors earlier assumed.. In fact many people have this disease since childhood but it is not identified till they grows adults .Many patients are identified as having a mild version of the disease but in its classic form, can quickly attack lungs.. In the 1950s, few children with cystic fibrosis lived to attend elementary school. Today, advances in research and medical treatments have further enhanced and extended life for children and adults with CF. Many people with the disease can now expect ...
In this work, we present an automatic method for liver segmentation and fibrosis classification in liver computed-tomography (CT) portal phase scans. The input is a full abdomen CT scan with an unknown number of slices, and the output is a liver volume segmentation mask and a fibrosis grade. A multi-stage analysis scheme is applied to each scan, including: volume segmentation, texture features extraction and SVM based classification. Data contains portal phase CT examinations from 80 patients, taken with different scanners. Each examination has a matching Fibroscan grade. The dataset was subdivided into two groups: first group contains healthy cases and mild fibrosis, second group contains moderate fibrosis, severe fibrosis and cirrhosis. Using our automated algorithm, we achieved an average dice index of 0.93 ± 0.05 for segmentation and a sensitivity of 0.92 and specificity of 0.81for classification. To the best of our knowledge, this is a first end to end automatic framework for liver ...
The relentless progression of renal disease is closely linked to the process of fibrosis, which is triggered by initial or ongoing injury. Although it is still a point of debate, there is literature to support a mechanistic rather than merely an associative role of fibrosis in progression of kidney disease [40]. This systematic review is a comprehensive evaluation of renal biomarkers that can be used in the detection of fibrosis as well as in the prediction of progression of renal disease. However, the development of a clinically useful biomarker is a sequential process that usually requires five phases; phase 1 identifies promising directions in preclinical studies, phase 2 is clinical assay validation and detection of established disease, phase 3 is biomarker prediction of clinical disease in longitudinal studies, phase 4 is prospective screening and finally phase 5 is impact of screening on disease burden [41]. This systematic review aimed to identify fibrosis biomarkers that achieved phase 2 ...
Ophthotech Corporation (New York, NY) has initiated the first of several planned expansion trials to investigate the potential role of Fovista (anti-platelet derived growth factor, anti-PDGF) combination therapy in reducing subretinal fibrosis, addressing suboptimal treatment response, and reducing treatment burden in wet-AMD patients receiving anti-VEGF monotherapy. The first expansion trial is a phase 2a open-label study investigating the potential role of anti-PDGF therapy in combination with anti-VEGF therapy in reducing subretinal fibrosis in wet-AMD patients.. The anti-PDGF phase 3 program consists of 3 clinical trials to evaluate the safety and efficacy of anti-PDGF for use in combination with anti-VEGF agents for the treatment of wet AMD. Ophthotech expects to enroll up to 1866 patients in the 3 trials in more than 225 centers worldwide and to have initial, topline data from the phase 3 clinical trial available in 2016..

The liver organ lymphocyte population is enriched with organic killer (NK) cells, which play a key part in sponsor protection against viral infection and tumor transformation. IL-4, IL-13, hedgehog ligands, and osteopontin; nevertheless, NKT cells may also attenuate liver organ fibrosis under particular circumstances by eliminating HSCs and by generating IFN-. Finally, the potential for NKT and NK cells to be used as therapeutic targets for anti-fibrotic therapy is talked about. proof for the contact between NK cells and early turned on HSCs. (that NK cells eliminate early turned on, but not really quiescent or turned on completely, HSCs. Initial, the amount of early turned on desmin positive HSCs with an oval form was considerably reduced in DDC-fed MLN9708 rodents after administration of the NK cell activator poly I:C (Radaeva and Gao, MLN9708 unpublished data). Second, immunohistochemistry MLN9708 studies present that early turned on HSCs and NK cells possess very similar distributions ...
Fibrosis is the excessive accumulation of extracellular matrix that often occurs as a wound healing response to repeated or chronic tissue injury, and may lead to the disruption of organ architecture and loss of function. Although fibrosis was previously thought to be irreversible, recent evidence indicates that certain circumstances permit the resolution of fibrosis when the underlying causes of injury are eradicated. The mechanism of fibrosis resolution encompasses degradation of the fibrotic extracellular matrix as well as elimination of fibrogenic myofibroblasts through their adaptation of various cell fates, including apoptosis, senescence, dedifferentiation, and reprogramming. In this Review, we discuss the present knowledge and gaps in our understanding of how matrix degradation is regulated and how myofibroblast cell fates can be manipulated, areas that may identify potential therapeutic approaches for fibrosis.. ...

A serious complication of radiotherapy in the treatment of cancer patients is the late onset of fibrosis in normal tissues. Transforming growth factor beta (TGF-beta) is emerging as a key mediator of the fibrotic process through its effects on stimulation of fibroblast proliferation, migration and extracellular matrix (ECM) synthesis. The fact that radiation-induced vascular injury tends to precede the development of fibrosis has led to the suggestion that vascular damage is crucial in its pathogenesis. CD105, the specific type III vascular receptor for TGF-beta1 and -beta3, modulates cell proliferation and ECM production in response to TGF-beta in vitro. In this study, we have quantified the levels of TGF-beta1 and soluble CD105-TGF-beta1 complex in 91 pre-radiotherapy plasma samples from early-stage (T1 or T2) breast cancer patients utilising an enhanced chemiluminescence ELISA system. During the follow-up period, 24 patients had developed moderate and one severe fibrosis of the breast. The ...

Alprostadil is sold in the United States as urethral suppositories and in injectable form. The suppositories are sold under the brand name Muse.[6] The injectable forms are Edex[7] and Caverject.[8] Muse delivers alprostadil as a penile suppository, inserted into the urethra, at least ten minutes before the erection is needed. Caverject and Edex are similarly fast-acting, but instead are injected by syringe directly into the corpus cavernosum of the penis. Alprostadil is also available as a generic. The major cost is that it must be mixed by a compounding pharmacy and supplies may be difficult to obtain. The different formulations, including Bimix and Trimix, may include papaverine and/or phentolamine. A typical mix might be 30 mg of papaverine, 2 mg of phentolamine, and 20 μg alprostadil. As a generic, it is much less expensive than the packaged injectables. It is premixed and must be kept refrigerated and the user must load a syringe with the quantity needed.
