Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

Hypersensitivity pneumonitis: experimental production in calves with antigens of Micropolyspora faeni. (1/31967)

Pneumonitis was induced in calves by exposure to aerosols of Micropolyspora faeni with or without prior sensitization of the animals by subcutaneous injection of antigen. The pneumonitis primarily involved centrolobular areas and was characterized by alveolar septal thickening and loss of air space by cellular infiltration. Vasculitis and focal haemorrhage occurred in certain individuals and haemoproteinaceous exudate appeared within septa and alveolar lumina. The pneumonitis was compared with human farmer's lung, pneumonitis of housed cattle and other experimental hypersensitivity pneumonitides.  (+info)

Systemic infection with Alaria americana (Trematoda). (2/31967)

Alaria americana is a trematode, the adult of which is found in mammalian carnivores. The first case of disseminated human infection by the mesocercarial stage of this worm occurred in a 24-year-old man. The infection possibly was acquired by the eating of inadequately cooked frogs, which are intermediate hosts of the worm. The diagnosis was made during life by lung biopsy and confirmed at autopsy. The mesocercariae were present in the stomach wall, lymph nodes, liver, myocardium, pancreas and surrounding adipose tissue, spleen, kidney, lungs, brain and spinal cord. There was no host reaction to the parasites. Granulomas were present in the stomach wall, lymph nodes and liver, but the worms were not identified in them. Hypersensitivity vasculitis and a bleeding diathesis due to disseminated intravascular coagulation and a circulating anticoagulant caused his death 8 days after the onset of his illness.  (+info)

Decreased liver and lung drug-metabolizing activity in mice treated with Corynebacterium parvum. (3/31967)

Injections of killed suspensions of Corynebacterium parvum (i.p.) in young male mice were followed by time- and dose-dependent decreases in the drug-metabolizing activity of liver microsomes and lung homogenates. In vitro assays with model substrates [aminopyrine, aniline, p-nitroanisole, and benzo(a)pyrene] were used to quantitate drug-metabolizing activity. It is likely that such decreases in mixed function oxidases activity will act to significantly alter the pharmacokinetics of concurrently or subsequently administered drugs. The results provide a possible mechanism to explain several previously reported immunochemotherapeutic interactions.  (+info)

Suppression of Moloney sarcoma virus immunity following sensitization with attenuated virus. (4/31967)

Murine sarcoma virus (Moloney strain) (MSV-M)-induced tumors are unusual in that they regularly appear less than 2 weeks after virus inoculation, progress for 1 to 2 weeks, and are rejected by normal adult BALB/c mice. Rejectio leaves the animals immune to tumor induction. In the present study, presensitization of normal adult BALB/c mice with attenuated MSV-M resulted in an altered pattern of tumor immunity. Injection of active MSV-M into the presensitized animals resulted in tumor induction and rejection similar to that observed in normal animals, but rejection failed to produce protection against the secondary inoculation with MSV-M. After the second inoculation with active MSV-M, tumors appeared and progressed but ultimately were rejected. Over 80% of the mice died, 25% after the primary challenge and the remainder after the secondary challenge. At death, all mice had histological evidence of leukemia which was the probable cause of death. The animals that died following the secondary challenge also had evidence of disseminated MSV-M. Solid tumor nodules were found in skeletal muscle distant from the original site of inoculation, and active MSV-M was isolated from spleen and lungs. The possibility that the results were produced by specific suppression of MSV-Moloney leukemia virus immunity is discussed.  (+info)

Factors influencing the deposition of inhaled particles. (5/31967)

Because the initial deposition pattern of inhaled particles of various toxic agents determines their future clearance and insult to tissue, respiratory tract deposition is important in assessing the potential toxicity of inhaled aerosols. Factors influencing the deposition of inhaled particles can be classified into three main areas: (1) the physics of aerosols, (2) the anatomy of the respiratory tract and (3) the airflow patterns in the lung airways. In the physics of aerosols, the forces acting on a particle and its physical and chemical properties, such as particle size or size distribution, density, shape, hygroscopic or hydrophobic character, and chemical reactions of the particle will affect the deposition. With respect to the anatomy of the respiratory tract, important parameters are the diameters, the lengths, and the branching angles of airway segments, which determine the deposition. Physiological factors include airflow and breathing patterns, which influence particle deposition. Various lung models used in predicting particle deposition are reviewed and discussed. The air-way structures of various animal species are compared, showing the unique structure of the human lung compared to the animal species under study. Regional deposition data in man and dog are reviewed. Recent deposition data for small rodents are presented, showing regional difference in deposition with the right apical lobe having the highest relative deposition.  (+info)

High-throughput screening of small molecules in miniaturized mammalian cell-based assays involving post-translational modifications. (6/31967)

BACKGROUND: Fully adapting a forward genetic approach to mammalian systems requires efficient methods to alter systematically gene products without prior knowledge of gene sequences, while allowing for the subsequent characterization of these alterations. Ideally, these methods would also allow function to be altered in a temporally controlled manner. RESULTS: We report the development of a miniaturized cell-based assay format that enables a genetic-like approach to understanding cellular pathways in mammalian systems using small molecules, rather than mutations, as the source of gene-product alterations. This whole-cell immunodetection assay can sensitively detect changes in specific cellular macromolecules in high-density arrays of mammalian cells. Furthermore, it is compatible with screening large numbers of small molecules in nanoliter to microliter culture volumes. We refer to this assay format as a 'cytoblot', and demonstrate the use of cytoblotting to monitor biosynthetic processes such as DNA synthesis, and post-translational processes such as acetylation and phosphorylation. Finally, we demonstrate the applicability of these assays to natural-product screening through the identification of marine sponge extracts exhibiting genotype-specific inhibition of 5-bromodeoxyuridine incorporation and suppression of the anti-proliferative effect of rapamycin. CONCLUSIONS: We show that cytoblots can be used for high-throughput screening of small molecules in cell-based assays. Together with small-molecule libraries, the cytoblot assay can be used to perform chemical genetic screens analogous to those used in classical genetics and thus should be applicable to understanding a wide variety of cellular processes, especially those involving post-transitional modifications.  (+info)

Interleukin-8 receptor modulates IgE production and B-cell expansion and trafficking in allergen-induced pulmonary inflammation. (7/31967)

We examined the role of the interleukin-8 (IL-8) receptor in a murine model of allergen-induced pulmonary inflammation using mice with a targeted deletion of the murine IL-8 receptor homologue (IL-8r-/-). Wild-type (Wt) and IL-8r-/- mice were systemically immunized to ovalbumin (OVA) and were exposed with either single or multiple challenge of aerosolized phosphate-buffered saline (OVA/PBS) or OVA (OVA/OVA). Analysis of cells recovered from bronchoalveolar lavage (BAL) revealed a diminished recruitment of neutrophils to the airway lumen after single challenge in IL-8r-/- mice compared with Wt mice, whereas multiply challenged IL-8r-/- mice had increased B cells and fewer neutrophils compared with Wt mice. Both Wt and IL-8r-/- OVA/OVA mice recruited similar numbers of eosinophils to the BAL fluid and exhibited comparable degrees of pulmonary inflammation histologically. Both total and OVA-specific IgE levels were greater in multiply challenged IL-8r-/- OVA/OVA mice than in Wt mice. Both the IL-8r-/- OVA/OVA and OVA/PBS mice were significantly less responsive to methacholine than their respective Wt groups, but both Wt and IL-8r mice showed similar degrees of enhancement after multiple allergen challenge. The data demonstrate that the IL-8r modulates IgE production, airway responsiveness, and the composition of the cells (B cells and neutrophils) recruited to the airway lumen in response to antigen.  (+info)

Lung fluid transport in aquaporin-1 and aquaporin-4 knockout mice. (8/31967)

The mammalian lung expresses water channel aquaporin-1 (AQP1) in microvascular endothelia and aquaporin-4 (AQP4) in airway epithelia. To test whether these water channels facilitate fluid movement between airspace, interstitial, and capillary compartments, we measured passive and active fluid transport in AQP1 and AQP4 knockout mice. Airspace-capillary osmotic water permeability (Pf) was measured in isolated perfused lungs by a pleural surface fluorescence method. Pf was remarkably reduced in AQP1 (-/-) mice (measured in cm/s x 0.001, SE, n = 5-10: 17 +/- 2 [+/+]; 6.6 +/- 0.6 AQP1 [+/-]; 1.7 +/- 0.3 AQP1 [-/-]; 12 +/- 1 AQP4 [-/-]). Microvascular endothelial water permeability, measured by a related pleural surface fluorescence method in which the airspace was filled with inert perfluorocarbon, was reduced more than 10-fold in AQP1 (-/-) vs. (+/+) mice. Hydrostatically induced lung interstitial and alveolar edema was measured by a gravimetric method and by direct measurement of extravascular lung water. Both approaches indicated a more than twofold reduction in lung water accumulation in AQP1 (-/-) vs. (+/+) mice in response to a 5- to 10-cm H2O increase in pulmonary artery pressure for five minutes. Active, near-isosmolar alveolar fluid absorption (Jv) was measured in in situ perfused lungs using 125I-albumin as an airspace fluid volume marker. Jv (measured in percent fluid uptake at 30 min, n = 5) in (+/+) mice was 6.0 +/- 0.6 (37 degrees C), increased to 16 +/- 1 by beta-agonists, and inhibited to less than 2.0 by amiloride, ouabain, or cooling to 23 degrees C. Jv (with isoproterenol) was not affected by aquaporin deletion (18.9 +/- 2.2 [+/+]; 16.4 +/- 1.5 AQP1 [-/-]; 16.3 +/- 1.7 AQP4 [-/-]). These results indicate that osmotically driven water transport across microvessels in adult lung occurs by a transcellular route through AQP1 water channels and that the microvascular endothelium is a significant barrier for airspace-capillary osmotic water transport. AQP1 facilitates hydrostatically driven lung edema but is not required for active near-isosmolar absorption of alveolar fluid.  (+info)

In order to make this discovery, they conducted the experiment in three steps. First, they injected the lung protein alone inside frog eggs to measure its function. Second, they injected both the M2 protein from H1N1 virus and the lung protein inside frog eggs and found that the H1N1 virus M2 protein caused the lung protein function to decrease significantly. By means of molecular biology techniques, scientists isolated the segment of the H1N1 virus M2 protein responsible for the damage to the lung protein and were able to demonstrate that without this segment, the H1N1 virus was unable to damage the lung protein. Third, an intact, full H1N1 virus M2 protein and the lung protein were then re-injected into frog eggs along with antioxidant drugs. This also prevented H1N1 virus M2 protein from damaging the lung protein. When these experiments were repeated using human lung cells, the results were exactly the same ...

AU - Matsumoto, Kenji. AU - Saito, Hirohisa. AU - Matsuda, Akio. PY - 2010/11/15. Y1 - 2010/11/15. N2 - IL-33 is a member of the IL-1 family and mediates its biological effects via the ST2 receptor, which is selectively expressed on Th2 cells and mast cells. Although polymorphic variation in ST2 is strongly associated with asthma, it is currently unclear whether IL-33 acts directly on lung tissue cells at sites of airway remodeling. Therefore, we aimed to identify the IL-33-responsive cells among primary human lung tissue cells. ST2 mRNA was expressed in both endothelial and epithelial cells but not in fibroblasts or smooth muscle cells. Correspondingly, IL-33 promoted IL-8 production by both endothelial and epithelial cells but not by fibroblasts or smooth muscle cells. Transfection of ST2 small ...
In recent years, significant progress has been made in dissecting the genetic control of mammalian lung development. Many transcription factors, peptide growth factors and their receptors, as well as extracellular matrix components have been identified as important regulators of lung morphogenesis in reverse genetics approaches (Warburton et al. 2000; Groenman et al. 2004; Kumar and Ryan 2004). Chemical mutagenesis using the potent germline mutagen ENU represents a powerful means to complement these gene-driven approaches by phenotype-based screens in mice (De Angelis et al. 2000; Nolan et al. 2000; Kile et al. 2003). This report describes the positional cloning of the perinatal lethal, ENU-induced l7Rn64234SB allele and identifies a pivotal role for the previously hypothetical gene NM_026304 in Clara cell function during mouse lung development. The ENU-induced nonsense mutation truncated the carboxy-terminal 17 aa, rendering the l7Rn64234SB protein unstable. However, detection of residual ...

Image: by Phil Schatz License: CC BY 4.0. Basically, a distinction is made between right and left lung. The left lung consists of two cloth (Lobi superior and inferior pulmonis sinistri), which are separated from each other by the fissura obliqua. The right lung, in turn, consists of three lobes (lobi superior, medius and inferior pulmonis dextri). The subdivision is done by the Fissura obliqua and the Fisura horizontalis pulmonis dextri. These fissures extend deep into the lung tissue and are, like the surface of the lung, lined with the visceral pleura.. The further structure is identical in both lungs. One distinguishes between the lung tip (Apex pulmonis), the lung base (Base pulmonis), the lung surfaces and the lung margins. The lung surface is covered by a serous skin, the visceral pleura, and appears pale pink in the healthy to gray. Depending on the position and the relationship to the thorax one differentiates with the lung surfaces (Facies pulmonis) between the facies costalis, ...

Pulmonary hemorrhage and peripheral microvascular defects were found in approximately half of the newborn Foxf1(+/-) mice, which expressed low levels of lung Foxf1 mRNA [low-Foxf1(+/-) mice]. Microvascular development was normal in the surviving newborn high-Foxf1(+/-) mice, which compensated for pulmonary Foxf1 haploinsufficiency and expressed wild-type Foxf1 levels. To identify expression of genes regulated by Foxf1, we used Affymetrix microarrays to determine ...

While the adult murine lung utilizes multiple restricted progenitor cells during homeostasis and fix compartmentally, very much less is known about the progenitor cells from the human lung. fix utilizing murine versions have got provided essential ideas into both lung regeneration and homeostasis. These research have got proven that the adult mouse lung epithelium can be fairly quiescent and will not really adhere to the traditional control cell model [1]. Rather, the lung shows up to conform to a maintenance structure identical to that of various other tissue with gradual turnover prices, such as the pancreas [2], [3]. During regular tissues homeostasis, abundant facultative progenitor cells located throughout the lung epithelium mediate any 1420477-60-6 manufacture required maintenance. These facultative progenitor cells, Clara cells and Type II pneumocytes, are quiescent and function as differentiated cells of the mature lung epithelium, but keep the capability to differentiate and self-renew ...
Bronchopulmonary dysplasia (BPD) remains a major respiratory illness in extremely premature infants. The biological mechanisms leading to BPD are not fully understood, although an arrest in lung development has been implicated. The current study aimed to investigate the occurrence of autophagy in the developing mouse lung and its regulatory role in airway branching and terminal sacculi formation. We found 2 windows of epithelial autophagy activation in the developing mouse lung, both resulting from AMPK activation. Inhibition of AMPK-mediated autophagy led to reduced lung branching in vitro. Conditional deletion of beclin 1 (Becn1) in mouse lung epithelial cells (Becn1Epi-KO), either at early (E10.5) or late (E16.5) gestation, resulted in lethal respiratory distress at birth or shortly after. E10.5 Becn1Epi-KO lungs displayed reduced airway branching and sacculi formation accompanied by impaired vascularization, excessive epithelial cell death, reduced mesenchymal thinning of the interstitial ...

For normal lifelong lung function, the prerequisites are: (1) normal lung function at birth; (2) normal growth in lung function until the adult plateau at 20-25 years of age; and (3) no accelerated deterioration from the plateau. Cohort studies have established that lung function either tracks or deteriorates, but never improves, after the preschool years.26-28 Thus, lung function in adult life is critically dependent on in utero and post-natal lung development.. An important antenatal factor affecting newborn lung function is maternal smoking, which causes structural effects on the developing lung.29 A study in more than 13 000 people showed that childhood disadvantage defined by either maternal or paternal asthma, childhood asthma, maternal smoking and childhood respiratory infections predicts worse adult lung function, a faster rate of lung function decline, and a greater prevalence of COPD.30 Other important influences include maternal antibiotic31 and paracetamol32 use, maternal ...

Optimal lung health from embryo through adulthood requires the complex interaction of pulmonary airspaces, interstitial and vasculature, beginning with organ development and culminating in programmed senescence. Technological advances have fostered a growing appreciation for the impact of cellular plasticity and the importance of cellular niche both during development and in response to both injury and repair. In addition to expanding the role of reactivation of developmental pathways lung repair, recent discoveries have demonstrated unique aging programs that will provide novel treatment strategies for chronic lung disease. The 5th Gordon Research Conference on Lung Development, Injury and Repair in August of 2019 seeks to attract cutting edge science to drive forward the field of lung development, injury, and repair toward the goal of facilitating novel therapeutic approaches to maximize lung health across the lifespan. This conference will strive to highlight new concepts behind the interactions
The lung is the main organ in the respiratory system and doesnt develop till about week 4 in the embryo. This stage of development is known as the Embryonic stage that covers the period of week 4-5 of the developing embryo. In this stage the 2 lung buds would have formed and lung lobes and the bronchopulmonary segments. The stem diverticulum will have differentiated into trachea and larynx. The Pseudoglandular stage is the period from 6 weeks to 16 weeks in the growing fetus. The events that occur in this stage include the formation of extensive airway branching of about 14 or more generations of branching resulting in terminal bronchioles. The conducting epithelium tubes are formed and are surrounded by thick mesenchyme. At 2 months all of the segmental bronchi would have formed. The distal structures at this stage are lined with cuboidal epithelium. The next stage is the Canalicular stage, from the period of week 16 to 25. The terminal bronchioles divide into two or more respiratory ...

Research in the Cardoso lab focuses on the mechanisms that regulate lung progenitor cell fate during lung development and on the contribution of developmental mechanisms to disease pathogenesis and regeneration-repair of the adult lung. We are investigating how progenitor cells generate the wide diversity of cell types of the mature respiratory system. In this context, we have been identifying early markers of cell fate and characterizing the genetic programs associated with acquisition of the various airway epithelial cell phenotypes as the lung forms. These studies have provided insights into the role of specific pathways, including retinoids, Fgf, Tgf beta and Notch in controlling the specification and expansion of lung progenitors, airway branching and differentiation of the various lung epithelial cell lineages. Over these years Our studies continue to explore the basic mechanisms of lung development, using this knowledge to understand the role of stem/progenitor cells in lung ...
Epithelia from lung rudiments in which secondary bronchial buds are already established (14th and 13th gestational day for rat and mouse respectively) are able to undergo branching morphogenesis and cytodifferentiation in submandibular mesenchyme in vitro, whereas lung epithelium from one day younger foetuses rarely gives a morphogenetic response to submandibular mesenchyme and usually differentiates into primary (non-budding) bronchial epithelium.. The failure of 13-day rat lung epithelium to respond to submandibular mesenchyme can be prevented by peeling off the submandibular mesenchyme from the lung epithelium after 2½ days culture and replacing the same mesenchyme, or renewing it with fresh salivary mesenchyme ex vivo. Changes in the epithelial contour are visible by 10 h and buds form within 24 h; this is followed by branching morphogenesis in more than 66% of the samples.. The number of cells in S-phase in the epithelium is doubled within 3 to 5 h after the operation and the number of ...

Lung cancer is a malignant tumour in the tissue of one or both lungs. A tumour may be found in the bronchi or in the spongy lung tissue. A tumour that starts in the lung is known as a primary lung cancer. Tumours in the lung may also be due to cancer which has spread through the blood from another part of the body such as the breast, bowel, or prostate - these cancers are called lung secondary or metastases. The following information refers to primary lung cancer.. Like other cancers, lung cancer is the result of the uncontrolled growth and multiplication of cells in the lung(s). Over time, this abnormal cell growth develops into a progressively larger mass which starts to invade functional parts of the lung, affecting breathing, causing pain and symptoms related to the loss of normal lung function. Doctors call this abnormal cluster of cells a tumour. These abnormal cells grow and divide uncontrollably and, if left untreated, eventually spread throughout the body.. ...
Aim: Chronic exposure to indoxacarb and pulmonary expression of toll-like receptor 9 (TLR-9) in mice.. Materials and Methods: In this study, healthy male Swiss albino mice (n=30) aging 8-10 weeks were used to evaluate TLR-9 expression in lungs of mice following indoxacarb exposure with and without lipopolysaccharide (LPS). Indoxacarb was administered orally dissolved in groundnut oil at 4 and 2 mg/kg/day for 90 days. On day 91, five animals from each group were challenged with LPS/normal saline solution at 80 μg/animal. The lung tissues were processed for real time and immunohistochemical studies.. Results: LPS resulted increase in fold change m-RNA expression level of TLR-9 as compare to control, while indoxacarb (4 mg/kg) alone and in combination with LPS resulted 16.21-fold change and 29.4-fold change increase in expression of TLR-9 m-RNA, respectively, as compared to control. Similarly, indoxacarb (2 mg/kg) alone or in combination with LPS also altered TLR-9 expression. Further at protein ...
When lung cells are injured, there seems to be a cross talk between the damaged cells, the lung endothelial cells and the stem cells, explains Lee.. Lee and Kim are still trying to eavesdrop on this cross-talk, but one key factor produced by endothelial cells is a protein called thrombospondin (TSP-1). By adding it to 3-D cultures exposed to the air, mimicking the lung environment, Kim and Lee were able to prod even a single lung stem cell to start churning out alveolar cells. And by simply taking the TSP-1-rich liquid surrounding cultured endothelial cells and injecting it into the mice, they were able to reverse the lung damage caused by pulmonary fibrosis.. Conversely, when the researchers engineered lung endothelial cells to lack TSP-1 and added them to the 3-D cultures, the stem cells went down a different pathway, producing more airway cells. And in live mice unable to make TSP-1, airway repair was enhanced after injury.. TSP-1 is clearly a potential target for manipulation in patients ...

With the increasing prevalence of more infective and/or virulent strains of influenza, understanding the impact of virus on the host epithelium and the processes involved in lung repair are of great importance, says John F. Alcorn, PhD, an immunologist affiliated with the department of pediatrics at the Childrens Hospital of Pittsburgh of UPMC. He notes that the findings open up new possibilities for developing therapeutic agents that promote recovery of normal lung function and architecture after influenza infection and lessen the likelihood of secondary infections. A key finding is that even after the resolution of infection, influenza results in lung parenchymal remodeling that may be critical to susceptibility to further injury, says Dr. Alcorn. This series of experiments used 6- to 8-week-old wild-type (WT) mice (C57BL/6 strain) as well as IL-22-deficient mice, infected with influenza A PR/8/34 H1N1 or control vehicle. To determine the distribution of IL-22 in the lung, they used ...
You know that smoking is bad for your lungs, but what does that mean? Heres what you need to know about the smokers lung vs. healthy lung discussion.
Stress is defined as the force applied to a material, while strain is the consequent deformation. In the whole lung, stress can be roughly approximated by the transpulmonary pressure, whereas the approximation of the average strain is the change in volume relative to the lung resting volume. The same tidal volume per kilogram may result in completely different strain according to the size of the baby lung (the V0 of the previous equation). For example, a 70-kg man with ARDS may have, according to the severity of the lung injury, a residual baby lung equal to 60%, 40%, or 20% of his normal lung size. If the ventilator is set to deliver 10 mL/kg, the actual delivered tidal volume would generate an alveolar strain, which would result from the application, in normal lung, of a tidal volume equal to 17 mL/kg, 25 mL/kg, and 50 mL/kg, values associated with a significant lung injury in laboratory studies. Recently we attempted to quantify the relationship between stress-strain and VILI in healthy ...

Work in the Robert H. Brown Lab explores several topics within pulmonary physiology, with a long-term goal of understanding the structural changes in the lungs that lead to the pathophysiology of lung disease. Our core studies examine the structure-function relationship of pulmonary airways and vessels as well as their role in chronic obstructive pulmonary disease (COPD) and reactive airway disease. Recent research has involved studying the mechanisms and treatment of COPD progression, new methods for treating asthma, and lung inflation and airway hyperresponsiveness. We are also exploring the impact of HIV infection on the etiology of lung disease and the pathophysiologic consequences of lung distention.. Research Areas: asthma, HIV, pulmonary physiology, lung disease, COPD, reactive airway disease ...
The NF-kappaB pathway has been shown to play a critical role in both adaptive and innate immunity and has been implicated as a focal point for induction of lung inflammation by a variety of inflammatory stimuli; however, the role of NF-kappaB in specific lung cell types remains unclear. We hypothesized that individual cell types in the lungs make important and unique contributions to the NF-kappaB dependent innate immune response. To determine the temporal and cell specific activation of NF-kappaB in vivo, an NF-kappaB reporter mouse in which expression of an enhanced green fluorescent protein (eGFP)/luciferase fusion protein cDNA driven by an NF-kappaB inducible promoter (NGL mouse) was generated. NF-kappaB activity was detected in intact, anesthetized animals by bioluminescence imaging and at the cellular level by detection of GFP on lung tissue sections. Using Eschericia coli lipopolysaccharide (LPS) and Pseudomonas aeruginosa models of lung inflammation, the timing and duration of NF-kappaB ...
To understand lung cancer, we must first understand the lungs. The lungs are two sponge-like organs in the chest. The right lung has three sections, called lobes. The left lung has two lobes. It is smaller because the heart takes up more room on that side of the body. The lungs bring air in and out, taking in oxygen and getting rid of carbon dioxide gas, which is a waste product of the body.. The lining which surrounds the lungs is called the pleura. The pleura protects the lungs. The windpipe, or trachea, brings air down into the lungs, and divides into tubes called bronchi, which divide into smaller branches called bronchioles. At the end of these small branches are tiny air sacs known as alveoli.. Most lung cancers start in the lining of the bronchi. But lung cancer can also begin in other areas such as the trachea, bronchioles, or alveoli. Lung cancer usually takes many years to develop.. ...
Patients who survive an acute lung injury are able to recover their lung function, suggesting that adult lungs regenerate to a certain extent. Depending on the cause and severity of the injury, multiple progenitor cells, including alveolar type II cells and distal airway stem cells, have been shown to drive lung tissue regeneration in mice. Now, Vaughan et al. describe another cell type involved in the repair process in mouse models lung damage from influenza virus infection or bleomycin inhalation: the rare lineage-negative epithelial progenitor (LNEP).. LNEP cells are quiescently present within normal distal mouse lung and do not express mature lineage markers, such as club cell 10 (CC10) protein and surfactant protein C (SPC). However, the authors demonstrate that these cells are activated to proliferate and migrate to damaged sites and mediate lung remodeling following major injury. Using lineage tracing approaches and cell transplantation, Vaughan et al. showed that LNEP cells, but not ...
Dendritic cells (DCs) residing in the lung are known to acquire inhaled Ag and, after migration to the draining bronchial lymph node (brLN), to present it to naive T cells in an either tolerogenic or immunogenic context. To visualize endogenous lung-derived DCs, we applied fluorescent latex beads (LXs) intratracheally, thereby in vivo labeling the majority of phagocytic cells within the lung. Of note, LX-bearing cells subsequently arriving in the draining brLN were found to represent lung-derived migratory DCs. Imaging explanted brLN by two-photon laser-scanning microscopy, we quantitatively analyzed the migration and interaction behavior of naive CD4+ T cells and endogenous, lung-derived DC presenting airway-delivered Ag under inflammatory or noninflammatory conditions. Ag-specific naive CD4+ T cells engaged in stable as well as transient contacts with LX-bearing DCs in both situations and displayed similar overall motility kinetics, including a pronounced decrease in motility at 16-20 h after ...
The use of the porcine lung to demonstrate recruitment maneuvers stimulated us to consider the possibility of using the ASL 5000 to investigate ways to improve protocols for the handling of ex-vivo perfused lungs. We believe this would provide interesting research projects for students and faculty. Many of the current ex-vivo perfusion protocols involve using positive pressure and high concentrations of oxygen to maintain isolated perfused lungs. The longest time that perfused lungs have been kept viable ex-vivo is about 10 hours. Using the ASL 5000 to model breathing, we would like to explore the possibility of extending survival time of ex-vivo perfused lungs. We believe that lowering the FiO2 and avoiding positive pressure ventilation could improve viability. Further development of this model could lead to advances in therapeutics related to airway clearance, mechanical ventilation, and airway pharmacology.. In the video below, the porcine lungs are attached to an Avea ventilator in the CPAP ...
Through the use of developmental and knock out studies Mig-6 has been shown to have a role in development. It has also been shown to be a tumour suppressor gene. Little work has been done as yet looking at its role in the adult. This study examined the role of Mig-6 in the lung with the ultimate goal being to determine if the pulmonary phenotype due to Mig-6 ablation is due to a developmental programming or loss of function in the adult. This was investigated in two ways. 1. To investigate if knocking out Mig-6 in adult lung has an effect on lung function2. Investigate the role of Mig-6 in lung epithelial cells by RNAi (Investigation of the Role of Mig-6 in Pulmonary Epithelial Cells and Vascular Cells In Vitro).Knocking out Mig-6 in the adult mice showed no difference in epithelial markers and after staining morphology and airway size were found to be normal. This would seem to indicate that the Mig-6 phenotype is due to altered development of the lungs during the neonatal period and not due to a loss
Goal of the present study is to investigate the specific cellular responses to nCeO2 and nFe2O3 in various lung cell types and develop an in vitro chronic exposure model to predict the potential fibrogenic and carcinogenic effects. Primary human lung fibroblasts were treated with nCeO2 (size dXRD = 17 nm, SSA = 61 m2/g) and direct stimulation of collagen production (a hallmark of fibrosis) was evaluated. In separate experiments, primary human small airway epithelial cells were exposed to a sub-lethal concentration (0.625 µg/cm2) of nCeO2 and nFe2O3 (size dXRD = 20 nm, SSA = 50 m2/g) for 6 weeks and their effects on cell transformation and invasion were evaluated. Our results showed new data that nCeO2 can induce a dose-dependent increase in collagen production by lung fibroblasts; nCeO2 can induce proliferation of lung epithelial cells as compared to vehicle-treated control and nFe2O3 induced neoplastic transformation of epithelial cells as determined by soft-agar colony formation assay and transwell

YALE (US)-Scientists have achieved an important first step in regenerating fully functional lung tissue that can exchange gas-the key role of the lungs.. Details appear in the June 24 issue of Science Express.. Lung disease accounts for around 400,000 deaths each year in the United States. Lung tissue is difficult to regenerate because it does not generally repair or regenerate beyond the microscopic level.. The only current way to replace damaged adult lung tissue is to perform lung transplantation, which is highly susceptible to organ rejection and infection and achieves only 10 percent to 20 percent survival at 10 years.. The researchers goal was to see if it was possible to successfully implant tissue-engineered lungs, cultured in vitro, that could serve the lungs primary function of exchanging oxygen and carbon dioxide.. They took adult rat lungs and first removed their existing cellular components, preserving the extracellular matrix and hierarchical branching structures of the airways ...
The Lung Scan provides a detailed visualization of the lungs. The Advanced Lung Analysis software allows highly accurate volume measurement of lung nodules. With its 3D volume measurement, we are better able to determine changes in nodule volume and to quantify growth rate and doubling time for lesions, allowing earlier and more accurate identification of small lung cancers. This enables our radiologists to detect lung cancer at its earliest stage, usually undetectable by an ordinary chest x-ray.. The Lung Scan can also detect other lung damage such as emphysema from smoking or lung scarring from prior infection. ...
Caveolin-1 is a key regulator of pulmonary endothelial barrier function. interleukin-6, and promoted BAL neutrophilia in WT mice. Lung injury by these criteria was significantly reduced in Cav-1-/- mice but fully restored by i.v. injection of liposome/Cav-1 cDNA complexes that rescued expression of Cav-1 in lung microvessels. As thrombin is known to play a significant role in mediating stretch-induced vascular injury, we observed in cultured mouse lung microvascular endothelial cells (MLECs) thrombin-induced albumin hyperpermeability and phosphorylation of p44/42 MAP kinase in WT but not in Cav-1-/- MLECs. Thus, caveolin-1 expression is required for mechanical stretch-induced lung inflammation and endothelial hyperpermeability in vitro and in vivo. was measured in isolated lung preparations explanted from mice after two hours of injurious or control ventilation. The procedure is usually described in detail by Gorovoy in WT and Cav-1-/- mice (Fig. 2). For 125I-BSA determination, mice were ...
Small airways are abnormal in asthma [1]. One measurement of small airway function is Sacin, derived from the multiple-breath nitrogen washout (MBNW) test. Sacin reflects ventilation heterogeneity in diffusion-dependent airways, and is correlated with airway hyperresponsiveness [2] and asthma control [3]. Theoretically, heterogeneity of diffusion-dependent ventilation can arise due to the heterogeneity of cross-sectional areas of airway openings in terminal airways and the acini [4]. Therefore, Sacin may be affected by structural changes in those airways. The elastic properties of the lung may also affect Sacin, as the phase III slope, a marker of ventilation heterogeneity derived from the single-breath nitrogen washout, correlates with lung compliance in explanted lungs of smokers and in healthy lungs [5]. ...
Among adults in the United States, the prevalence of reduced lung function including obstructive and restrictive lung disease is about 20%, representing an over 40 million adults. Persons with reduced lung function often demonstrate chronic systemic inflammation, such as from elevated levels of C-reactive protein. Substantial data suggests that inflammation may have a significant role in the association between reduced lung function and cardiovascular disease (CVD); however, how reduced lung function predicts CVD as risk modification remains largely unknown. Poor lung function has been shown to be a better predictor of all-cause and cardiac-specific mortality than established risk factors such as serum cholesterol, and CVD is the leading cause of mortality among those with impaired lung function. The exact mechanism of atherosclerosis is not clear, but persistent low grade inflammation is considered as one of the culprits in clot formation. The initial presentation of coronary heart disease is either
The lung is an organ constantly exposed to microbiota either through inhalation or subclinical microaspiration from birth. Historically, medical texts allude to a sterile lung environment, and this dogma has persisted in contemporary medicine. In the last decade, a revolution of sorts has taken place in our understanding of how the lung and microbiota interact and exist. This revolution stems from new knowledge that the lung is not sterile (10) and, in fact, harbors an abundance of diverse interacting microbiota. As mentioned above, the gut microbiome modulates host mucosal defense (11, 12); however, there is a paucity of information regarding the potential role of lung microbiota to regulate immunity and homeostasis.. The lung is not sterile, contrary to centuries of dogma asserting the same. Throughout the 1900s this inference was reinforced by respiratory culture-based protocols that sought only to identify clinically significant pathogens and by a spurious conclusion that upper respiratory ...
Primary human lung cells or cell lines were cultured on a stretchable silastic membrane forming the bottom of a 12-well plexiglas® box. The box was connected to an adult ventilator and ventilated for up to 36 hours at 20 cycles/min with a pressure-volume regimen resembling that of MV. Several lung cell types were tested in this model. The alveolar macrophage was identified as the main cellular source of key inflammatory mediators, such as tumor necrosis factor, the chemokine interleukin (IL)-8, and matrix metalloproteinase-9, produced during mechanical ventilation. Mechanical ventilation also induced low levels of IL-8 secretion by human alveolar epithelial type II-like cells. Other lung cell types such as endothelial cells, bronchial cells, and fibroblasts failed to produce IL-8 in response to mechanical ventilation (1,2). Conclusions and Relevance for 3R ...
