It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.

Several different forms of the human protein exist ranging from 18-24 kDa in size due to the use of alternative start sites within the fgf-2 gene. It has a 55 percent amino acid residue identity to FIBROBLAST GROWTH FACTOR 1 and has potent heparin-binding activity. The growth factor is an extremely potent inducer of DNA synthesis in a variety of cell types from mesoderm and neuroectoderm lineages. It was originally named basic fibroblast growth factor based upon its chemical properties and to distinguish it from acidic fibroblast growth factor (FIBROBLAST GROWTH FACTOR 1).Antibodies, Monoclonal, Humanized: Antibodies from non-human species whose protein sequences have been modified to make them nearly identical with human antibodies.

(Dorland, 27th ed)Wound Healing: Restoration of integrity to traumatized tissue.RNA, Messenger: RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.Dendrimers: Tree-like, highly branched, polymeric compounds.

Visual acuity can also be influenced by brightness, color, and contrast.Vasa Vasorum: Nutrient blood vessels which supply the walls of large arteries or veins.Mice, Knockout: Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.Intravitreal Injections: The administration of substances into the VITREOUS BODY of the eye with a hypodermic syringe.Enzyme-Linked Immunosorbent Assay: An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.Intercellular Signaling Peptides and Proteins: Regulatory proteins and peptides that are signaling molecules involved in the process of PARACRINE COMMUNICATION. They are generally considered factors that are expressed by one cell and are responded to by receptors on another nearby cell.

In vivo significance of ICAM-1--dependent leukocyte adhesion in early corneal angiogenesis. (1/340)

PURPOSE: Numerous investigations have stressed the significance of leukocytes in early angiogenesis. Leukocytes invade the cornea, and the location of their extravasation corresponds to the site of vessel ingrowth. The interactions between leukocytes and vascular endothelium are mediated by various proteins, including adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1). In this study, the role of ICAM-1 during early corneal angiogenesis was evaluated in vivo. METHODS: Corneal neovascularization was induced in New Zealand White rabbits by use of intrastromal pellets containing 750 ng vascular endothelial growth factor (VEGF). The fluorescent dye rhodamine 6G was used to stain leukocytes in vivo. Leukocyte adhesion and vessel growth were quantified in vivo by high-resolution fluorescence angiography. To inhibit ICAM-1 interactions a microemulsion containing anti-ICAM-1 antibody was applied topically. RESULTS: Limbal vessels showed increased leukocyte adhesion 24 hours after pellet implantation: The number of rolling and sticking leukocytes was significantly increased compared with the number in control animals (P < 0.01). Treatment with anti-ICAM-1 antibody resulted in reduced leukocyte sticking and increased leukocyte rolling. The area covered by new blood vessels was significantly diminished in eyes treated with anti-ICAM-1 (P < 0.05). CONCLUSIONS: The results support the hypothesis that ICAM-1-mediated leukocyte adhesion is a key event in early angiogenesis. This model may serve for investigation of the significance of adhesion molecules by in vivo observation and quantification.  (+info)

Suppression of angiogenesis and tumor growth by the inhibitor K1-5 generated by plasmin-mediated proteolysis. (2/340)

Proteolytic enzymes are involved in generation of a number of endogenous angiogenesis inhibitors. Previously, we reported that angiostatin, a potent angiogenesis inhibitor, is a proteolytic fragment containing the first four kringle modules of plasminogen. In this report, we demonstrate that urokinase-activated plasmin can process plasminogen to release an angiogenesis inhibitor, K1-5 (protease-activated kringles 1-5). K1-5 inhibits endothelial-cell proliferation with a half-maximal concentration of approximately 50 pM. This inhibitory effect is endothelial-cell-specific and appears to be at least approximately 50-fold greater than that of angiostatin. A synergistic efficacy of endothelial inhibition was observed when angiostatin and kringle 5 (K5) were coincubated with capillary endothelial cells. The synergistic effect is comparable to that produced by K1-5 alone. Systemic treatment of mice with K1-5 at a low dose significantly blocked the fibroblast growth factor-induced corneal neovascularization, whereas angiostatin had no effect at the same dose. K1-5 also suppressed angiogenesis in chicken embryos. Systemic administration of K1-5 at a low dose at which angiostatin was ineffective significantly suppressed the growth of a murine T241 fibrosarcoma in mice. The antitumor effect correlates with the reduced neovascularization. These findings suggest that the plasmin-mediated proteolysis may be involved in the negative switch of angiogenesis.  (+info)

Expression of cell adhesion molecules on limbal and neovascular endothelium in corneal inflammatory neovascularization. (3/340)

PURPOSE: To investigate the expression of cell-adhesion molecules on corneolimbal and neovascular endothelium and the associated leukocyte infiltration in an experimental model of inflammatory corneal neovascularization (NV). METHODS: Corneal NV was induced in BALB/c mice by placement of nylon sutures. Interleukin-1 receptor antagonist (IL-1ra) was used topically to determine whether suppression of IL-1 could affect adhesion molecule expression and leukocytic infiltration. At set time points, corneal samples were analyzed immunohistochemically for expression of P-selectin, E-selectin, intercellular adhesion molecule (ICAM)-1, vascular adhesion molecule (VCAM)-1, and platelet- endothelial adhesion molecule (PECAM)-1. Leukocytic infiltration at different time points was quantified histologically. In companion experiments mice deficient in ICAM-1 were investigated to determine the functional relevance of this molecule in corneal leukocyte infiltration. RESULTS: Significant enhanced expression of ICAM-1 was detected on the corneolimbal vascular endothelium as early as 8 hours and on the newly formed corneal NV by day 3, and treatment with IL-1ra led to significant suppression of this expression. IL-1ra-induced suppression of ICAM-1 expression was accompanied by a profound decrease in corneal leukocytic infiltration by 44.6% at day 1 (P < 0.003), 71.8% at day 3 (P < 0.001), 60.1% at day 7 (P < 0.001), and 63.8% at day 14 (P < 0.001), compared with control corneas. Similarly, in ICAM-1 knockout mice, the corneal leukocytic infiltration was 50.3%, 52.9%, and 36.4%, compared with wild-type control animals on day 1 (P < 0.001), day 7 (P < 0.005), and day 14 (P < 0.001), respectively. Expression of PECAM-1 was constitutively present on perilimbal vascular endothelium and had no response to IL-1ra treatment. No significant expression of P-selectin, E-selectin, or VCAM-1 was detected in this experimental model. CONCLUSIONS: These results suggest that leukocytic infiltration in this model of inflammatory corneal NV is closely associated with ICAM-1 expression, and that topical IL-1ra displays corneal anti-inflammatory effects, largely by suppressing ICAM-1 expression on vascular endothelial cells.  (+info)

VEGF contributes to postnatal neovascularization by mobilizing bone marrow-derived endothelial progenitor cells. (4/340)

Vascular endothelial growth factor (VEGF) has been shown to promote neovascularization in animal models and, more recently, in human subjects. This feature has been assumed to result exclusively from its direct effects on fully differentiated endothelial cells, i.e. angiogenesis. Given its regulatory role in both angiogenesis and vasculogenesis during fetal development, we investigated the hypothesis that VEGF may modulate endothelial progenitor cell (EPC) kinetics for postnatal neovascularization. Indeed, we observed an increase in circulating EPCs following VEGF administration in vivo. VEGF-induced mobilization of bone marrow-derived EPCs resulted in increased differentiated EPCs in vitro and augmented corneal neovascularization in vivo. These findings thus establish a novel role for VEGF in postnatal neovascularization which complements its known impact on angiogenesis.  (+info)

Inhibition of rat corneal angiogenesis by 16-kDa prolactin and by endogenous prolactin-like molecules. (5/340)

PURPOSE: The cornea is an avascular organ, where induction of new blood vessels involves the turn-on of proangiogenic factors and/or the turn-off of antiangiogenic regulators. Prolactin (PRL) fragments of 14 kDa and 16 kDa bind to endothelial cell receptors and inhibit angiogenesis. This study was designed to determine whether antiangiogenic PRL-like molecules are involved in cornea avascularity. METHODS: Sixteen-kDa PRL and basic fibroblast growth factor (bFGF) or anti-PRL antibodies were placed into rat cornea micropockets and neovascularization evaluated by the optical density associated with capillaries stained by the peroxidase reaction and by the number of vessels growing into the implants. Prolactin receptors in corneal epithelium were investigated by immunocytochemistry. RESULTS: bFGF induced a dose-dependent stimulation of corneal neovascularization. This effect was inhibited by coadministration of 16-kDa PRL, as indicated by a 65% reduction in vessel density and a 50% decrement in the incidence of angiogenic responses. Corneal angiogenic reactions of different intensities were induced by implantation of polyclonal and monoclonal anti-PRL antibodies. Corneal epithelial cells were labeled by several anti-PRL receptor monoclonal antibodies. CONCLUSIONS: These findings show that exogenous 16-kDa PRL inhibits bFGF-induced corneal neovascularization and suggest that PRL-like molecules with antiangiogenic actions function in the cornea. PRL receptors in the corneal epithelium may imply that PRL in the cornea derives from lacrimal PRL internalized through an intracellular pathway. These observations are consistent with the notion that members of the PRL family are potential regulators of corneal angiogenesis.  (+info)

Nitric oxide synthase-II is expressed in severe corneal alkali burns and inhibits neovascularization. (6/340)

PURPOSE: Inducible nitric oxide synthase (NOS-II) is expressed in many inflammatory conditions. The implication of nitric oxide (NO) in angiogenesis remains controversial. The role of NOS-II and its influence on angiogenesis in corneal neovascularization is unknown and was investigated in this study. METHODS: A mouse model of corneal neovascularization induced by chemical cauterization was used. NOS-II mRNA expression was analyzed by reverse transcriptase-polymerase chain reaction, and NOS-II protein was studied in situ by immunohistochemical analysis of the cornea. The influence of NOS-II on neovascularization was determined by comparison of vessel development in "normal" wild-type mice and mice with a targeted disruption of the NOS-II gene. RESULTS: NOS-II mRNA was induced to very high levels after corneal cauterization and remained upregulated throughout the disease. Migratory cells in the center of the cauterization area expressed NOS-II protein. The neovascular response in mice lacking the NOS-II gene was significantly stronger than in wild-type mice, and the difference increased over time. CONCLUSIONS: These data are the first evidence that NOS-II is expressed in this model of sterile corneal inflammation. NOS-II expression inhibited angiogenesis in severe corneal alkali burns.  (+info)

IFN-gamma-inducible protein-10 attenuates bleomycin-induced pulmonary fibrosis via inhibition of angiogenesis. (7/340)

Few studies have addressed the importance of vascular remodeling in the lung during the development of bleomycin-induced pulmonary fibrosis (BPF). For fibroplasia and deposition of extracellular matrix to occur, there must be a geometric increase in neovascularization. We hypothesized that net angiogenesis during the pathogenesis of fibroplasia and deposition of extracellular matrix during BPF are dependent in part on a relative deficiency of the angiostatic CXC chemokine, IFN-gamma-inducible protein-10 (IP-10). To test this hypothesis, we measured IP-10 by specific ELISA in whole lung homogenates in either bleomycin-treated or control mice and correlated these levels with lung hydroxyproline. We found that lung tissue from mice treated with bleomycin, compared with that from saline-treated controls, demonstrated a decrease in the presence of IP-10 that was correlated to a greater angiogenic response and total lung hydroxyproline content. Systemic administration of IP-10 significantly reduced BPF without any alteration in lung lymphocyte or NK cell populations. This was also paralleled by a reduction in angiogenesis. Furthermore, IP-10 had no direct effect on isolated pulmonary fibroblasts. These results demonstrate that the angiostatic CXC chemokine, IP-10, inhibits fibroplasia and deposition of extracellular matrix by regulating angiogenesis.  (+info)

Effects of 1alpha,25-dihydroxyvitamin D3 on Langerhans cell migration and corneal neovascularization in mice. (8/340)

PURPOSE: To examine the effects of 1alpha,25-dihydroxyvitamin D3 (1alpha,25[OH]2D3), a hormone that has immunosuppressive properties, on Langerhans cell (LC) migration and corneal neovascularization in mouse corneas. METHODS: Two 10-0 nylon interrupted sutures were placed in the center of 50 BALB/c mouse corneas to induce LC migration and corneal neovascularization. The mice were then randomly assigned to one of five groups. Three groups (n = 11, n = 11, n = 6) received topical 1alpha,25(OH)2D3 (at concentrations of 10(-7) M, 10(-)8 M, 10(-9) M), one group (n = 11) received vehicle only, and one group (n = 11) received no eye drops. Instillation (three times a day) began on the first day after suturing. Corneal neovascularization was assessed by slit lamp microscopy and scored according to the length of newly formed corneal vessels. Fourteen days after suturing, the number of LCs that had migrated into the central corneal epithelium was counted by an immunofluorescence assay using an anti-Ia antibody. RESULTS: The number of LCs in the central cornea was 21.9 +/- 2.8 cells/mm2 in the nontreated group and 17.8 +/- 3.9 cells/mm2 in the vehicle-only group. Significantly fewer LCs were detected in all groups that had received 1alpha,25(OH)2D3 compared with the vehicle only and nontreated groups (10(-7) M: 7.4 +/- 1.2 cells/mm2, 10(-8) M: 7.2 +/- 2.0 cells/mm2, 10(-9) M: 6.2 +/- 0.7 cells/mm2). Moderate inhibition of corneal vascularization was observed in the 10(-7) M 1alpha,25(OH)2D3 group, but not the other groups. CONCLUSIONS: Topical administration of 1alpha,25(OH)2D3 can be effective in suppressing ocular surface inflammation by inhibiting LC migration into mouse corneas.  (+info)

Purpose: : To evaluate the effect of topically administered diclofenac, ketorolac, and etanercept on experimental corneal neovascularization. Methods: : Chemical cauterization of the cornea in 32 eyes of 32 rats was performed using silver nitrate sticks to induce corneal neovascularization. Topical instillation of diclofenac (Volteran, Novartis Pharmaceuticals), ketorolac (Acular, Allergan), and etanercept (Enbrel, Immunex Corp.) was compared to normal saline treatment for inhibition of neovascularization for 7 days. All animals were treated in accordance with the ARVO guidelines on the care and use of animals in research. The animals were randomly divided in 4 groups. Group 1 (n=8) received balanced salt solution (control), group 2 (n=8) received ketorolac 0.5 %, group 3 (n=8) received diclofenac 0.1%, and group 4 (n=8) received 200 µg/ml of etanercept. Percentage area of cornea covered by neovascularization and scar in each group was calculated separately by use of computer software on ...
The purpose of the study is to test the investigational drug Gamunex-C on the growth of blood vessels over the cornea. This study is being conducted by Dr. Balamurali Ambati at the Moran Eye Center at the University of Utah.. The cornea is the clear outer front part of the eye. In corneal neovascularization, blood vessels grow over the cornea. Corneal neovascularization and ocular anterior segment inflammations are sight-threatening conditions. Lipid deposition and edema with subsequent scar formation can compromise corneal clarity irreversibly. Corneal neovascularization is also a well recognized risk factor for corneal graft failure. In its natural state, the cornea is a site of immune privilege well suited to tissue transplantation. Once vascularized, there is direct exposure of corneal antigens to circulating host immune mechanisms greatly increasing the chance of rejection [Collaborative Corneal Transplantation Study].. Melting or inflammation in the anterior chamber, cornea, or ocular ...
Corneal neovascularization (CNV) is the in-growth of new blood vessels from the pericorneal plexus into avascular corneal tissue as a result of oxygen deprivation. Maintaining avascularity of the corneal stroma is an important aspect of corneal pathophysiology as it is required for corneal transparency and optimal vision. A decrease in corneal transparency causes visual acuity deterioration. Corneal tissue is avascular in nature and the presence of vascularization, which can be deep or superficial, is always pathologically related. Corneal neovascularization is a sight-threatening condition that can be caused by inflammation related to infection, chemical injury, autoimmune conditions, post-corneal transplantation, and traumatic conditions among other ocular pathologies. Common causes of CNV within the cornea include trachoma, corneal ulcers, phylctenular keratoconjunctivitis, rosacea keratitis, interstitial keratitis, sclerosing keratitis, chemical burns, and wearing contact lenses for ...
Pathologic angiogenesis is involved in cancer and several blinding conditions such as wet age-related macular degeneration, proliferative retinopathies and corneal neovascularization.. In these dieseases, the angiogenic triggers are hypoxia and inflammation, and both involve the main angiogenic mediator, which is Vascular Endothelial Growth Factor (VEGF). Among available treatments, anti-VEGF often shows limited or temporary efficacy, while steroids are potentially responsible for many side-effects. This thesis presents a series of linked studies aimed at elucidating the early pathologic changes leading to inflammation and corneal neovascularization, and how various treatments affect this process. In this thesis, anti-inflammatory and anti-angiogenic treatments are applied in corneal neovascularization models, to identify VEGF-independent pathways and other novel factors as future therapy targets, as well as to investigate the endogenous modulation of angiogenesis.. A model of experimental ...
Corneal Neovascularization (CNV), the extensive growth of blood vessels from conjunctiva into the cornea. It is a sight-threatening condition that can decreases eyesight and even leads to blindness. The pathologic growth of blood vessels impairs light transmission, promotes scar formation and causes inflammations, which harm visual acuity. Abnormal angiogenesis plays an important role in the process of CNV, which may result from corneal wound healing. Neovascular eye disease is one of the most common eye diseases in clinical admissions. CNV blinds approximately 7 million people worldwide. Continued mechanistic studies are a key to the prevention and treatment of CNV. Research in CNV animal models is essential in eye diseases. Several main methods of CNV models preparation are summarized in this review.
Due to its noninvasive accessibility and clarity, cornea serves an ideal target for evaluating the efficacy of various treatments against corneal disorders. A multitude of potential gene therapies based on different genes and strategies have been tried in the context of corneal diseases, including corneal NV. For example, various viral-mediated gene delivery systems have been proposed to produce expression of the desired genes with varying expression levels and duration [32-34]. In the case of gene therapy for corneal NV, as in many other situations, it is well recognized that targeting a single gene often fails to ensure the theoretically predicted efficacy [23,35-37]. We therefore investigated the possibility of better management of corneal NV by combining different anti-angiogenic factors in the present study. We showed that the combination of two or three genes exhibited additive effects over a single gene in inhibiting HUVEC proliferation in vitro (Figure 1A). This additive effect, however, ...
Anti-VEGF antibodies including off-label bevacizumab (Avastin™, Genentech), ranibizumab (Lucentis™, Genentech), and aflibercept (VEGF Trap-eye (VTE), Eylea) are presently used for the management of various retinal vascular abnormalities [72]. These drugs are different in their pharmacokinetics, structure, and molecular weight. Ranibizumab and aflibercept, which received Food and Drug Administration (FDA) approval for the treatment of neovascular age-related macular degeneration, were designed specifically for intravitreal injection.. Bevacizumab is a full-length humanized murine monoclonal IgG1 antibody with a molecular weight of 149 kDa that received FDA approval for the management of different cancers. 93% and 7% of amino acid sequences of this drug are similar to the human IgG1 and murine antibody, respectively [73]. Bevacizumab recognizes all isoforms of VEGF-A. Despite being off-label, it is used commonly as an intravitreal injection for the management of various retinal diseases [74]. ...

Gene Signal is currently developing aganirsen GS-101 (an antisense oligonucleotide or short naturally occurring DNA strand). GS-101 is a topical medication in the form of eye drops, and is currently being researched for the management of excessive vascular growth in the cornea, also known as neovascularisation GS-101 is a copy of a naturally occurring human gene and acts by inhibiting the expression of IRS-1, a protein required for the formation and growth of new blood vessels. By blocking the expression of this protein in pro-angiogenic conditions (in this case, those with excessive vascular growth), GS-101 inhibits and regresses corneal neovascularisation, which interferes with vision and may be the cause of graft rejection. Phase I, Phase II and Phase III clinical studies have been completed for Gene Signal s GS-101 in the management of Corneal Graft Rejection associated with Neovascularisation (excessive vascular growth of the cornea). The Phase I trial evaluated the safety of GS-101 is ...
Inflammatory angiogenesis is the pathogenic mechanism of various sight-threatening eye diseases, among them corneal neovascularization. Current treatment options include steroids which have undesirable side effects, or anti-VEGF which has only limited efficacy. In an inflammatory environment, however, angiogenesis can be stimulated by numerous factors not directly targeted by anti-VEGF therapy. The aim of this study was to induce corneal inflammation leading to angiogenesis, and investigate the early, differential effects of steroid and anti-VEGF therapy at the cellular, tissue, and gene expression levels. Fifty-two Wistar rats received a single intrastromal corneal suture to induce a controlled inflammatory angiogenic response. Rats were subsequently treated with dexamethasone, rat specific anti-VEGF, or goat IgG (control), topically 4 times daily for 7 days. In vivo confocal microscopy of the cornea was performed longitudinally from 5 h up to 7 d to investigate morphology at the cellular and ...

Results Autologous cultivated oral mucosal epithelial sheets were successfully generated for all 17 patients. All patients were followed up for more than 36 months; the mean follow-up period was 55 months and the longest follow-up period was 90 months. During the long-term follow-up period, postoperative conjunctivalisation and symblepharon were significantly inhibited. All eyes manifested various degrees of postoperative corneal neovascularisation, but it gradually abated and its activity was stable at 6 months after surgery. Best-corrected visual acuity was improved in 18 eyes (95%) during the follow-up periods, and visual acuity at the postoperative 36th month was improved in 10 eyes (53%). ...
RESULTS: The receptors for LXA4, ALX/Fpr-rs-2 and for RvE1, ChemR23 were each expressed by epithelium, stromal keratocytes, and infiltrated CD11b(+) cells in corneas. Compared to the vehicle-treated eye, ATLa-, RvD1-, and RvE1-treated eyes had reduced numbers of infiltrating neutrophils and macrophages and reduced mRNA expression levels of TNF-alpha, IL-1 alpha, IL-1 beta, VEGF-A, VEGF-C, and VEGFR2. Animals treated with these mediators had significantly suppressed suture-induced or IL-1 beta-induced hemangiogenesis (HA) but not lymphangiogenesis. Interestingly, only the application of ATLa significantly suppressed VEGF-A-induced HA ...

PURPOSE To report the outcomes of corneal fine needle diathermy (FND) with adjuvant intrastromal and subconjunctival bevacizumab injection for corneal neovascularization (CN) in children. METHODS Medical records of all children who had undergone FND with adjuvant bevacizumab injection were reviewed retrospectively. Treatment efficacy was evaluated by changes in visual acuity, regression of CN, and clearing of lipid deposits with the aid of slit-lamp color images that were taken before surgical intervention and at last follow-up visit. Postoperative complications were recorded and served to assess the safety of the procedure. RESULTS Nine eyes of 9 patients were included in the study. The mean age of the patients was 8.4 ± 4.2 years (4-15 years) and the mean follow-up time was 18.7 ± 12.2 months (5-35 months). Three eyes had a history of herpes simplex keratitis (HSK), 3 eyes had complete corneal anesthesia, 2 eyes had CN following suture tract infection after corneal transplant for HSK scar and

This is our initial experience with FND represented in only 2 cases, therefore definitive conclusions couldnt be established. Nevertheless, based on our results and after reviewing the two largest series published since FND was described, we found this technique simple, inexpensive and effective in occluding established corneal vessels, the main recognized risk factor for corneal graft rejection and failure. The lack of any major intra and postoperative complications reinforces the safety profile of the procedure. FND can be repeated and performed in any small eye unit around the world, as it does not require specialized equipment ...

DESCRIPTION (provided by applicant): The overall aim of this grant is to elucidate the novel linkage between copper transport protein Antioxidant1 (Atox1) and NADPH oxidase involved in inflammatory angiogenesis. Ischemic disease is a leading cause of morbidity and mortality in worldwide. Neovascularization is an important repair process in response to ischemia, which depends on angiogenesis, inflammation and reactive oxygen species (ROS). Copper (Cu), an essential micronutrient, is involved in physiological repair processes such as wound healing and angiogenesis as well as in various pathophysiologies including tumor growth, atherosclerosis and inflammatory diseases. Since excess Cu is toxic, bioavailability of intracellular Cu is tightly controlled by Cu transport proteins such as Cu chaperone Atox1. Our laboratories provided the first evidence that Atox1 functions as a Cu-dependent transcription factor to regulate Cu-induced cell growth. Furthermore, we are one of the first to demonstrate that ...

Cornea engraftment is the most common organ transplantation practiced around the world. The cornea is totally devoid of blood or lymphatic vessels, except in a peripheral zone called the limbus. This property, named "corneal angiogenic privilege", is conserved among all mammals to maintain cornea transparency and optimal visual acuity. In pathological conditions such as trauma, infections or hypoxia, blood and lymphatic vessels can grow into the avascular cornea, reducing visual acuity. In case of keratoplasty, it also considerably increases the risk of cornea graft rejection and is so considered as a high-risk keratoplasty. Treatments improving cornea survival after transplantation need to be developed, notably aiming at blocking corneal neovascularization. ...
We investigated the role of interleukin 8 (IL-8) in mediating angiogenesis in human bronchogenic carcinoma. Increased quantities of IL-8 were detected in tumor tissue as compared with normal lung tissue. Immunohistochemical staining of tumors revealed primary localization of IL-8 to individual tumor cells and demonstrated the capacity of tumor to elaborate IL-8. Functional studies that used tissue homogenates of tumors demonstrated the induction of both in vitro endothelial cell chemotaxis and in vivo corneal neovascularization. It is important to note that the addition of neutralizing antisera to IL-8 to these assays resulted in the marked and specific attenuation of these responses. Our observations definitively establish IL-8 as a primary mediator of angiogenesis in bronchogenic carcinoma and offer a potential target for immunotherapies against solid malignancies. ...

A question that has been raised in deliberations over why angiogenesis trials in humans have not demonstrated the robust therapeutic effects seen in earlier animal studies is whether the end points chosen for these trials were "correct"; ie, what is the definition of "successful" therapeutic neovascularization? Furthermore, were the measurement tools that were used to capture such end points adequately sensitive to detect them, even if they were present? Most scientists and clinicians would agree that successful neovascularization requires that new blood vessels be functional, supply the ischemic region with blood, and be stable over time. Our patients would emphasize that irrespective of whether the treatment makes them live longer, they would like to feel better, and hence quality of life is an important end point. Here, we consider whether the identification of molecular markers of neovascularization adds useful information and/or should be incorporated into the definition of "successful" ...

A limitation to the use of biologic therapies is the risk of significant systemic adverse events. Local administration achieves lower systemic exposure to the drug and therefore is likely associated with lower rates of severe adverse events. The use of infliximab eye drops has been investigated as an alternative modality for local drug delivery. The administration of topical infliximab eye drops reduced corneal opacity, perforation, and eyelid fibrosis in a mouse model of corneal alkali burn,19 and improved tear volume, corneal surface regularity, and goblet cell density in a mouse model of dry eye.20 In rabbit models, the use of topical infliximab prevented corneal neovascularization21 and suppressed subconjunctival wound healing after trabeculectomy.22 On the other hand, cerebrovascular accidents are recognized complications of systemic anti-VEGF therapy23 while anti-TNF-α agents are associated with a risk of opportunistic infections, malignancies, infusion reactions, as well as cardiac and ...

AU - Schaff, Hartzell V. PY - 1990. Y1 - 1990. N2 - To determine possible mechanisms by which omental pedicles protect bronchial anastomoses from ischemia, we studied the angiogenic potential of a lipid extract of omentum. A rabbit cornea model was used to quantify neovascularization produced by methanol-chloroform extract of homogenized autologous omentum or perirenal fat. In 22 anesthetized rabbits, 10 μl of omental lipid extract was injected into the cornea. In each animal the opposite eye was used as a control and was injected with a similar volume of extract prepared from perirenal fat. The side of injection of autologous omental fat was randomized and was not known to the investigator who assessed neovascularization on days 4, 7, 14, and 21 after injection. Neovascularization was recorded on ...

On the face, a 6-0 or 7-0 monofilament suture maybe used, though fast-absorbing gut may be used on the eyelids and ears to obviate the need for suture removal. When the goal of the running alternating simple and vertical mattress suture placement is solely to encourage wound-edge eversion, fine-gauge suture material may be used on the extremities as well. Otherwise, 5-0 monofilament suture material is used if there is minimal tension, and 4-0 monofilament suture is useful in areas under moderate tension where the goal of suture placement is relieving tension as well as epidermal approximation. In select high-tension areas, 3-0 monofilament suture may be utilized as well. ...

The tissue sections were deparaffinized and rehydrated, and endogenous peroxidase activity was quenched with 0.6% H2O2 in methanol. A mouse monoclonal antibody (148.6.1.1, a kind gift from Dr C. Hart, ZymoGenetics, Seattle, Wash) was used for detection of bFGF. This antibody was raised against human recombinant bFGF, and its specificity was determined by Western blot analysis and with an affinity support column containing immobilized human recombinant bFGF.17 A previously described method served for detection of bFGF in MCs.11 Briefly, the sections were treated with hyaluronidase for antigen retrieval. To exclude nonspecific binding, the sections were incubated in a blocking solution containing 3% normal horse serum, 0.5% BSA, and 0.3% Triton X-100 in PBS. They were then incubated overnight with the anti-bFGF antibody (0.05 μg/mL) diluted in PBS containing 2% normal horse serum. The avidin-biotin complex method (ABC-AP Kit, Vector Laboratories) was used to detect the primary antibody with ...
Author Summary Herpes simplex virus-type 1 is the leading cause of infectious corneal blindness in the industrialized world. Most of the morbidity associated with the virus is due to the host response to episodic reactivation of latent virus. Corneal immunologic privilege is associated with a number of factors including the absence of blood and lymphatic vessels. Conversely, corneal hem (blood)- and lymph-angiogenesis driven by inflammation correlate with the loss of privilege. Neovascularization is a common phenomenon in HSV-1 keratitis that correlates with poor prognosis. We have previously discovered HSV-1 elicits corneal lymphangiogenesis through a unique mechanism involving vascular endothelial growth factor (VEGF)-A independent of that described for other insults including transplantation or bacterial infection. However, the viral-encoded product(s) that elicit host production of VEGF-A is(are) unknown. In this paper, we have identified infected cell protein-4 (ICP4) as the primary virus-encoded
The main result of this study is that CXCR3 expression positively modulates ischemia-induced neovascularization, likely through modulation of inflammatory cell infiltration within the ischemic area. This study also extends previous results on the role of MCP-1 in this process and shows a significant impairment in postischemic neovascularization in MCP-1-deficient mice.. Classically, inflammatory cells have been shown to promote neovascularization through various mechanisms, including production of angiogenic factors, secretion of proinflammatory cytokines, and increased matrix degradation.7-9 LPS-induced monocyte accumulation promotes vessel growth, whereas absence of macrophages is associated with a deficient neovascularization response.10,11 A specific role of T cells in this setting was also suggested in Nude mice and in CD4-deficient mice, which exhibit a marked reduction in the angiogenic/arteriogenic process.4,5 In this study, we showed that CXCR3 and its ligands CXCL-10 and CXCL-9 were ...
Cauterization - What is the definition or description of: cauterization? Heat treatment. Cauterization is the term for the use of a device which uses heat to treat tissues, most commonly at surgery to diminish bleeding but also externally for bleeding such as nasal bleeding. It can also be used to remove lesions on the skin like warts and moles.
In the PDT approach, a photosensitizer is administered intravenously, which selectively accumulates in the neovascularized tissue. A dose of carefully calculated laser light is administered directly to the lesions, which activates the photosensitizer causing death to the cells and destroying the vessels. It is important to note that the effect of PDT treatment is photochemical and there is no accompanying thermal reactions. Although the results are a stoppage of blood leakage from the disruption of the vessels, according to the results seen in the TAP study (Treatment of Age-Related Macular Degeneration with Photodynamic Therapy), as reported at the Vitreoretinal Update 99 meeting held just prior to the AAO, the effect appears to be temporary, and as many as four treatments per year may be needed. However, there are indications that the recurrance of bleeding should lessen with time. The problem is the cost of the treatment. Visudyne is expected to be priced at about $1200 per dose, and with ...

A topical, slow-release anti-angiogenic drug for treating eye diseases Ofra Benny, PhD and Robert DAmato, MD, PhD, Vascular Biology Program. This projects aim is to develop Lodamin as a drug for ophthalmology uses. Lodamin is a novel oral anti-angiogenic drug and a non-toxic derivative of TNP-470 with preclinical activity in oncology.. Angiogenesis-related eye diseases, such as diabetic retinopathy and macular degeneration are common. Effective anti-angiogenic therapies aim to delay the progression of these ophthalmic diseases and prevent vision loss. Currently there are no antiangiogenic drugs approved for corneal neovascularization but only indirect angiogenesis inhibitors such as steroids and immunosuppressants. For retinal angiogenesis-related diseases, such as Age-Related Macular Degeneration (AMD), the only antiangiogenic therapies available are based on targeting a single growth factor: Vascular Endothelial Growth Factor (VEGF). Contrary to these available treatments, Lodamin inhibits ...

To explore the general requirement of endothelial mTORC2 during embryonic and adolescent development, we knocked out the essential mTORC2 component Rictor in the mouse endothelium in the embryo, during adolescence and in endothelial cells in vitro. During embryonic development, Rictor knockout resulted in growth retardation and lethality around embryonic day 12. We detected reduced peripheral vascularization and delayed ossification of developing fingers, toes and vertebrae during this confined midgestational period. Rictor knockout did not affect viability, weight gain, and vascular development during further adolescence. However during this period, Rictor knockout prevented skin capillaries to gain larger and heterogeneously sized diameters and remodeling into tortuous vessels in response to FGF2. Rictor knockout strongly reduced extensive FGF2-induced neovascularization and prevented hemorrhage in FGF2-loaded matrigel plugs. Rictor knockout also disabled the formation of capillary-like ...

Our group previously reported the case of an 11.5-year-old 10-0 polypropylene suture retrieved from an eye with a recurrent subluxation of an iris sutured IOL.(4) That report concluded that this type of suture does not undergo significant biodegradation, but that the sharp edge of the eyelets of the IOL slowly cut through the suture. Price et al, utilizing light microscopy techniques to examine sutures from eyes with dislocated 10-0 polypropylene, sclerally sutured IOLs, showed that suture remnants displayed transverse clefting, which reduced the tensile strength of the suture.(5) In that report, the oldest retrieved suture was approximately 14 years, and 4 of 5 IOLs had eyelets used for fixation. We believe that suture placement through the eyelets accounts for recurrent subluxation in at least 4 of the 5 IOLs described by Price et al. The fifth eye had chronic iritis; in that case inflammation may have led to accelerated suture degradation ...

Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable. The practice was once widespread for treatment of wounds. Its utility before the advent of antibiotics was said to be effective at more than one level: To prevent exsanguination To close amputations Cautery was historically believed to prevent infection, but current research shows that cautery actually increases the risk for infection by causing more tissue damage and providing a more hospitable environment for bacterial growth. Actual cautery refers to the metal device, generally heated to a dull red glow, that a physician applies to produce blisters, to stop bleeding of a blood vessel, and for other similar purposes. The main forms of cauterization used today ...
The present study used a gene-targeting strategy to establish a novel role for EC-derived MMP-2 in neovascularization. We provided both in vitro and in vivo evidence that MMP-2 promotes the migratory and angiogenic capacity of cultured aortic EC and BM-derived EPC-like c-Kit+ cells and further neovessel growth. In line with recent studies indicating that certain MMPs are involved in EPC mobilization, our data underscore the critical role of MMP-2 in EPC mobilization into the circulation to support ischemia-induced neovascularization. The mechanisms underlying the impairment of ischemia-induced neovascularization in MMP-2-deficient mice are schematically represented in supplemental Figure X.. The capillary density, collateral artery, and blood flow in the ischemic tissues were much lower in MMP-2−/− mice than in MMP-2+/+ mice, despite the compensatory increase of MMP-9 expression and its activity and TIMP-1 expression. This suggested that endogenous MMP-2 contributes to ischemia-induced ...
A duplicated figure has resulted in an expression of concern for a paper in the American Journal of Pathology on a treatment for ocular neovascularization, which causes vision loss.. According to the notice, the corresponding author, David Shima, now at University College London, brought his concern to the journal. He called it a "genuine error" and stated that all the findings had been reproduced.. Unfortunately, Shima claimed the original data are missing, because the institution that owned the information - Eyetech Research Center - has "since gone through several acquisitions.". Ocular neovascularization occurs when growth signals in the eye stimulate the creation of many new blood vessels. Over time these blood vessels break, causing bleeding and scarring that limits vision. This is called "wet" macular degeneration.. The scientists found that giving patients drugs to limit two different growth factors at the same time is more effective than one at stopping the progression of AMD. This ...

Endothelial progenitor cells (EPCs) were first isolated as CD34+ mononuclear cells (MNCs) from adult peripheral blood.1,2 Tissue ischemia mobilizes EPCs from bone marrow to peripheral blood, and mobilized EPCs home specifically to sites of nascent neovascularization and differentiate into mature endothelial cells (ECs).3 The demonstrated role of EPCs in the physiological response to ischemia has led to the development of strategies of cell therapy for neovascularization in ischemic diseases. Intravenous transplantation of cultured human EPCs enhances neovascularization and improves limb salvage in nude mice with hindlimb ischemia.4 A similar strategy applied in a model of myocardial ischemia in the nude rat demonstrated that transplanted human EPCs incorporated into rat myocardial neovascularization, differentiated into mature ECs in ischemic myocardium, enhanced neovascularization, preserved left ventricular (LV) function, and inhibited myocardial fibrosis.5 Recently, Kocher et al6 attempted ...
The formation of new lymphatic vessels, or lymphangiogenesis, is a natural process involved in tissue repair and in the resolution of inflammatory reactions. In some cancers, this process is exploited by the tumor to promote its growth and its metastatic dissemination. Our group recently identified a role for the CD73-adenosine pathway in tumor angiogenesis. As angiogenesis and lymphangiogenesis are similar processes, often occurring in parallel, we suspect that the CD73-adenosine pathway could have a role in the regulation of lymphangiogenesis during inflammatory reactions and in the tumor microenvironment.. To confirm this hypothesis, we used in vivo models of inflammatory lymphangiogenesis induced by the administration of lipopolysaccharide (LPS) or Incomplete Freunds Adjuvant (IFA) in the peritoneal cavity of mice. These two models of peritonitis trigger the formation of new lymphatics in the diaphragm that can be analyzed by flow cytometry. To study tumor lymphangiogenesis, we used a ...

AU - Arbab, Ali Syed. PY - 2017/8/1. Y1 - 2017/8/1. N2 - Glioblastoma (GBM) is a hypervascular neoplasia of the central nervous system with an extremely high rate of mortality. Owing to its hypervascularity, anti-angiogenic therapies (AAT) have been used as an adjuvant to the traditional surgical resection, chemotherapy, and radiation. The benefits of AAT have been transient and the tumors were shown to relapse faster and demonstrated particularly high rates of AAT therapy resistance. Alternative neovascularization mechanisms were shown to be at work in these resilient tumors to counter the AAT therapy insult. Vascular Mimicry (VM) is the uncanny ability of tumor cells to acquire endothelial-like properties and lay down vascular patterned networks reminiscent of host endothelial blood vessels.

Choroidal neovascularization information including symptoms, causes, diseases, symptoms, treatments, and other medical and health issues.
One of the most innovative features of the ALLEGRETTO WAVE® Eye-Q is the way it uses wavefront-optimized technology to automatically compensate for the curvature of the cornea. In earlier laser correction systems, the "optical zone," or area of correction, was centered on the front of the cornea; the result was a flattened circular area that ended with an abrupt edge, causing unwanted side effects like poor night vision, glare, and halos.. The ALLEGRETTO WAVE® Eye-Q changes all that. The ALLEGRETTO WAVE® Eye-Q sends extra pulses to the peripheral corneal area in order to compensate for the angle of the laser beam. In this manner, the aspherical shape of the cornea is preserved to a degree that older lasers simply could not achieve. This compensation, combined with the incredibly small, 1mm size of the laser, produces a smooth, effective optical zone that results in what can only be described as seeing like never before.. Imagine a glass ball. If you took a flashlight and aimed it directly at ...

KS is characterized by the proliferation of characteristic spindle cells, neovascularization, and infiltration with inflammatory cells. The tumor, classically seen rarely and just in elderly subjects, has encountered a burst with HIV infection, being the most frequent tumor in AIDS patients (29). Although highly active retroviral therapy has hampered the tumor extent, KS still represents an important health problem, as many patients develop drug resistance and in most cases the duration of the response is limited (30). Notably, the majority of the patients are located in geographic regions with limited access to highly active retroviral therapy (31).. The highly vascular phenotype represents a hallmark for KS, and identification of pathways that contribute to its neovascularization is a priority for a potential efficient therapy. Here, we describe for the first time that both HIF-1α and HIF-2α, which are key players in angiogenesis, are expressed in AIDS-related KS biopsies. Moreover, we were ...

When your eyes are closed with contacts on, the oxygen exchange to your eye is inhibited even more than normal. This results in increased swelling of the cornea (edema) and can cause the contact lens to fit improperly, which can lead to acute red eye irritation. If the cornea is repeatedly deprived of oxygen (hypoxia), the eye may form new blood vessels (corneal neovascularization) or improperly formed cells that may rupture (corneal microcysts). Complications can change the surface and shape of the cornea, ultimately making it unsafe to wear contact lenses. To counter this, contact lens manufacturers have created extended wear contact lenses which increase the oxygen permeability of contact lenses. These contacts are approved for up to 30 days continuous wear, but these claims must be taken with caution. In the manufacturers own literature, only 80% of patients are expected to be able to achieve 30 days of continuous wear and 3-5% of wearers developed corneal inflammation accompanied with mild ...

In corneal transplantation a diseased or scarred cornea is replaced with a healthy one. Special microsurgical instruments are used to remove the diseased part of the cornea and replace it with a transparent donor cornea. Fine nylon sutures secure the donor cornea in place, and antibiotics are administered locally to prevent infection. The eye is dressed with sterile gauze pads and a protective shield. Following surgery, the eye needs to be protected and eye drops applied for several months to promote healing. Some patients get good vision in two to three months, while others must wait for complete healing, which occurs at about a year.. Corneal transplantation enjoys a high success rate. The most important factors determining success are the underlying disease process and the quality of the tissue used during transplantation. Should the body reject a new cornea, it can be successfully treated if medication is administered at the first sign of symptoms. For this reason, it is important that ...
Excessive neovascularization of atherosclerotic lesions increases plaque vulnerability and the susceptibility to rupture. Semaphorin 7A (Sema7A), a semaphorin family member, was recently reported to promote atherosclerotic plaque formation by mediating d-flow-induced endothelial phenotypic change and leukocyte adhesion. To extend our understanding of the proatherogenic role of Sema7A, we investigated the role of endothelial Sema7A in angiogenesis and atherosclerotic neovascularization. Sema7A overexpression in human umbilical vein endothelial cells (HUVECs) significantly upregulated VEGFA/VEGFR2 and promoted cell migration and angiogenesis. This enhancing effect was eliminated by the blockage of Sema7A receptor, β1 integrin. Inhibition of FAK or ERK1/2 downstream of β1 integrin signaling significantly inhibited cell migration and angiogenesis via ROCK (Rho-associated coiled forming protein kinase) and MYPT (myosin phosphatase targeting subunit), which are responsible for actin polymerization.

  • Gene-based antiangiogenic applications for corneal neovascularization. (semanticscholar.org)
  • Since the imbalance between proangiogenic agents and antiangiogenic agents primarily mediate the process of corneal neovascularization, recent therapies are intended to disrupt the different steps in the synthesis and actions of proangiogenic factors. (biomedcentral.com)
  • Corneal neovascularization is a sight-threatening condition that can be caused by inflammation related to infection, chemical injury, autoimmune conditions, post-corneal transplantation, and traumatic conditions among other ocular pathologies. (wikipedia.org)
  • The desired results from medical therapy may not always occur, ergo an invasive procedure may be needed to prevent further decrease in corneal avascularity. (wikipedia.org)
  • Preoperative corneal neovascularization (CNV) is thought to be associated with an increased rate of corneal graft failure and potentially also graft rejection. (nih.gov)
  • The company is now conducting an international phase III trial with GS-101 for the prevention of pathologic corneal neovascularization and thereby corneal graft rejection. (eyedocnews.com)
  • Since increased secretion of vascular endothelial growth factor (VEGF) [ 4 - 6 ] has been observed in corneal NV as well as in other ocular neovascularization, some of the efforts have been directed at blocking VEGF or its endothelial cell-specific receptors, namely vascular endothelial growth factor receptor 1 (Flt-1) and vascular endothelial growth factor receptor 2 (Flk-1). (molvis.org)
  • This study aims at investigating the effects and molecular mechanism of riboflavin-ultraviolet-A-induced cross-linking (corneal collagen cross-linking, CXL) on corneal neovascularization (CNV) in a rabbit alkali burn model. (hindawi.com)
  • Our results indicate that riboflavin-ultraviolet-A-induced cross-linking (corneal collagen cross-linking, CXL) significantly inhibits alkali burn-induced CNV in rabbits, possibly through downregulating VEGF, MMP-2, MMP-9, and TIMP-1 expression. (hindawi.com)
  • Moreover, in a corneal alkali burn model, epithelial defects are attenuated by CXL treatment, which suggests that CXL ameliorates the effects of acute corneal alkali burns [ 6 ]. (hindawi.com)
  • The combination of multiple anti-angiogenic genes might be necessary for effective therapy of corneal NV, although each of these pathways makes a potential target for the treatment of this disease. (molvis.org)
  • One of the most common causes of corneal neovascularization is iastrogenic pathology from contact lens wear. (wikipedia.org)
  • Please note that the autofluorescence for corneal epithelium should not be misinterpreted as positive staining. (nih.gov)
  • The group that received the GS-101 dose of 86 µg/day showed regression in 86% of patients compared with progression of neovascularization which occurred in 100% of the placebo group. (eyedocnews.com)
  • The authors say the study demonstrated that changes in the area of neovascularization, vessel diameter, distribution of vessel diameters, and, in some cases, vessel tortuosity were particularly evident on FA and ICGA and provided reliable measures of change. (aao.org)
  • Corneal tissue is avascular in nature and the presence of vascularization, which can be deep or superficial, is always pathologically related. (wikipedia.org)
  • After treatment, 8 eyes had complete CN resolution, and 1 eye with corneal anesthesia following brain tumor resection had partial regression in vessel distribution and size. (semanticscholar.org)
  • The 2 factors predictive of increased risk of neovascularization and graft failure were increased recipient age (P = 0.003) and male gender (P = 0.046). (nih.gov)
  • However, whether H19 regulates the progression of corneal neovascularization (CNV) is unclear. (bioscirep.org)
