Abstract
Introduction Visually normal areas of the lung with high attenuation on computed tomography (CT) imaging, termed CT lung injury, may represent injured but not yet remodelled lung parenchyma. This prospective cohort study examined if CT lung injury is associated with future interstitial features on CT and restrictive spirometry abnormality among participants from the Coronary Artery Risk Development in Young Adults (CARDIA) study. Methods CARDIA is a population-based cohort study. CT scans obtained at two time points were assessed objectively for amount of lung tissue characterised as CT lung injury and interstitial features. Restrictive spirometry was defined as having a forced vital capacity (FVC) <80% predicted with forced expiratory volume in 1 s/FVC ratio >70%. Results Among 2213 participants, the median percentage of lung tissue characterised as CT lung injury at a mean age of 40 years was 3.4% (interquartile range 0.8-18.0%). After adjustment for covariates, a 10% higher amount of CT lung injury at mean age 40 years was associated with a 4.37% (95% CI 3.99-4.74%) higher amount of lung tissue characterised as interstitial features at mean age 50 years. Compared to those with the lowest quartile of CT lung injury at mean age 40 years, there were higher odds of incident restrictive spirometry at mean age 55 years in quartile 2 (OR 2.05, 95% CI 1.20-3.48), quartile 3 (OR 2.80, 95% CI 1.66-4.72) and quartile 4 (OR 3.77, 95% CI 2.24-6.33). Conclusions CT lung injury is an early objective measure that indicates risk of future lung impairment.

Prevention of Bleomycin-Induced Pulmonary Inflammation and Fibrosis in Mice by Bilobalide. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2023; 2023:1973163. [PMID: 36733844 PMCID: PMC9889159 DOI: 10.1155/2023/1973163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 12/12/2022] [Accepted: 01/05/2023] [Indexed: 01/26/2023]
Abstract
Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease. Bilobalide (BB) is a sesquiterpene isolated from Ginkgo biloba, and its role in IPF is poorly understood. Mice were intratracheally instilled with 2.5 mg/kg bleomycin (BLM) to induce IPF and then treated with 2.5, 5, and 10 mg/kg BB daily for 21 days. Treatment with BB ameliorated pathological injury and fibrosis of lung tissues in BLM-induced mice. BB suppressed BLM-induced inflammatory response in mice as demonstrated by reduced inflammatory cells counts (leukocytes, neutrophils, macrophages, and lymphocytes) and pro-inflammatory factors (CCL2 and TNF-α), as well as increased CXCL10 levels in BALF. The expression of BLM-induced hydroxyproline, LDH, and pro-fibrotic mediators including fibronectin, collagen I, α-smooth muscle actin (α-SMA), transforming growth factor (TGF)-β1, matrix metalloproteinase (MMP)-2, and MMP-9 in lung tissue was inhibited by BB treatment, and the tissue inhibitor of metalloproteinase-1 (TIMP-1) expression was increased. BB blocked the phosphorylation of JNK and NF-κB, and the nuclear translocation of NF-κB in the lung tissue of mice induced by BLM. Additionally, it abated the activation of NLRP3 inflammasome in lung tissue induced by BLM, which led to the downregulation of IL-18 and IL-1β in BALF. Our present study suggested that BB might ameliorate BLM-induced pulmonary fibrosis by inhibiting the early inflammatory response, which is probably via the inhibition of the JNK/NF-κB/NLRP3 signal pathway. Thus, BB might serve as a therapeutic potential agent for pulmonary inflammation and fibrosis.

Abstract
The extracellular matrix (ECM) imparts critical mechanical and biochemical information to cells in the lungs. Proteoglycans are essential constituents of the ECM and play a crucial role in controlling numerous biological processes, including regulating cellular phenotype and function. Versican, a chondroitin sulfate proteoglycan required for embryonic development, is almost absent from mature, healthy lungs and is re-expressed and accumulates in acute and chronic lung disease. Studies using genetically engineered mice show that the versican-enriched matrix can be pro- or anti-inflammatory depending on the cellular source or disease process studied. The mechanisms whereby versican develops a contextual ECM remain largely unknown. The primary goal of this review is to provide an overview of the interaction of versican with its many binding partners, the "versican interactome," and how through these interactions, versican is an integrator of complex extracellular information. Hopefully, the information provided in this review will be used to develop future studies to determine how versican and its binding partners can develop contextual ECMs that control select biological processes. While this review focuses on versican and the lungs, what is described can be extended to other proteoglycans, tissues, and organs.

J Dermatol Sci 2021; 104:201-209. [PMID: 34844843 DOI: 10.1016/j.jdermsci.2021.11.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 09/17/2021] [Accepted: 11/04/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND Systemic sclerosis (SSc) is a systemic autoimmune disease characterized by excessive fibrosis. FcγRIIB is a low-affinity receptor for the Fc fragment of IgG. FcγRIIB is expressed on the surface of various leukocyte subsets and signals negative feedback pathways to down-regulate B-cell antigen receptor signaling. OBJECTIVE The aim of the present study was to investigate the role of FcγRIIB in the development of a murine bleomycin-induced scleroderma model. METHODS The experimental fibrosis model was generated by the intradermal injection of bleomycin into wild-type (WT) and FcγRIIB-deficient (FcγRIIB-/-) mice. We histologically assessed skin and lung fibrosis as well as inflammatory cell infiltration. Cytokine and chemokine expression levels were measured with RT-PCR. RESULTS The severity of fibrosis in the skin and lung was significantly worse in FcγRIIB-/- mice than in WT mice. In the skin of bleomycin-treated mice, the numbers of CD8+ T cells, F4/80+ macrophages, MPO+ neutrophils, NK1.1+NK cells, and B220+ B cells were significantly higher in FcγRIIB-/- mice than in WT mice. The expression of TNF-α and IL-1β was significantly higher in FcγRIIB-/- mice than in WT mice as was the expression of ICAM-1, CXCL2, and CCL3 in the affected skin. An adoptive transfer of splenic leukocytes from FcγRIIB-/- mice into WT mice showed exacerbated skin and lung fibrosis compared to WT mice without an adoptive transfer. CONCLUSION These results indicate that FcγRIIB plays an inhibitory role in skin and lung fibrosis. Moreover, modulating FcγRIIB signaling has potential as a therapeutic approach for SSc.

Abstract
Radiation-induced pulmonary fibrosis is a common severe long-time complication of radiation therapy for tumors of the thorax. Current therapeutic options used in the clinic include only supportive managements strategies, such as anti-inflammatory treatment using steroids, their efficacy, however, is far from being satisfactory. Recent studies have demonstrated that the development of lung fibrosis is a dynamic and complex process, involving the release of reactive oxygen species, activation of Toll-like receptors, recruitment of inflammatory cells, excessive production of nitric oxide and production of collagen by activated myofibroblasts. In this review we summarized the current state of knowledge on the pathophysiological processes leading to the development of lung fibrosis and we also discussed the possible treatment options.

Therapeutic Effect of Neuraminidase-1-Selective Inhibition in Mouse Models of Bleomycin-Induced Pulmonary Inflammation and Fibrosis. J Pharmacol Exp Ther 2020; 376:136-146.

Abstract
Pulmonary fibrosis remains a serious biomedical problem with no cure and an urgent need for better therapies. Neuraminidases (NEUs), including NEU1, have been recently implicated in the mechanism of pulmonary fibrosis by us and others. We now have tested the ability of a broad-spectrum neuraminidase inhibitor, 2,3-dehydro-2-deoxy-N-acetylneuraminic acid (DANA), to modulate the in vivo response to acute intratracheal bleomycin challenge as an experimental model of pulmonary fibrosis. A marked alleviation of bleomycin-induced body weight loss and notable declines in accumulation of pulmonary lymphocytes and collagen deposition were observed. Real-time polymerase chain reaction analyses of human and mouse lung tissues and primary human lung fibroblast cultures were also performed. A predominant expression and pronounced elevation in the levels of NEU1 mRNA were observed in patients with idiopathic pulmonary fibrosis and bleomycin-challenged mice compared with their corresponding controls, whereas NEU2, NEU3, and NEU4 were expressed at far lower levels. The levels of mRNA for the NEU1 chaperone, protective protein/cathepsin A (PPCA), were also elevated by bleomycin. Western blotting analyses demonstrated bleomycin-induced elevations in protein expression of both NEU1 and PPCA in mouse lungs. Two known selective NEU1 inhibitors, C9-pentyl-amide-DANA (C9-BA-DANA) and C5-hexanamido-C9-acetamido-DANA, dramatically reduced bleomycin-induced loss of body weight, accumulation of pulmonary lymphocytes, and deposition of collagen. Importantly, C9-BA-DANA was therapeutic in the chronic bleomycin exposure model with no toxic effects observed within the experimental timeframe. Moreover, in the acute bleomycin model, C9-BA-DANA attenuated NEU1-mediated desialylation and shedding of the mucin-1 ectodomain. These data indicate that NEU1-selective inhibition offers a potential therapeutic intervention for pulmonary fibrotic diseases. SIGNIFICANCE STATEMENT: Neuraminidase-1-selective therapeutic targeting in the acute and chronic bleomycin models of pulmonary fibrosis reverses pulmonary collagen deposition, accumulation of lymphocytes in the lungs, and the disease-associated loss of body weight-all without observable toxic effects. Such therapy is as efficacious as nonspecific inhibition of all neuraminidases in these models, thus indicating the central role of neuraminidase-1 as well as offering a potential innovative, specifically targeted, and safe approach to treating human patients with a severe malady: pulmonary fibrosis.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a systemic autoimmune disease that is characterized by excessive fibrosis. CD22 and CD72 are B cell-specific cell surface molecules that negatively regulate B cell function. OBJECTIVE The aim of the present study was to investigate the roles of CD22 and CD72 in a murine scleroderma model. METHODS The experimental fibrosis model was generated by subcutaneous injection of bleomycin or hypochlorous acid (HOCL) into wild-type (WT), CD22-deficient (CD22-/-), CD72-deficient (CD72-/-) and CD22 and CD72 double-deficient (CD22-/-/CD72-/-) mice. We histologically assessed skin fibrosis and inflammatory cell infiltration. Cytokine and chemokine expression levels were measured by real-time polymerase chain reaction. RESULTS The severity of fibrosis in the skin and lung was significantly less in CD22-/-, CD72-/-, and CD22-/-/CD72-/- mice than in WT mice in the bleomycin-induced model. In the skin of bleomycin-treated mice, the numbers of CD3+ T cells, CD8+ T cells, and F4/80+ macrophages were significantly lower in CD22-/-, CD72-/-, and CD22-/-/CD72-/- mice than in WT mice. The expression levels of mRNAs for IL-6, TNF-α, TGF-β, CTGF, IL-1β, IL-13, CXCL2, and ICAM-1 were significantly lower in CD22-/-, CD72-/-, and CD22-/-/CD72-/- mice than in WT mice. In the HOCL-induced model, both skin and lung fibrosis were ameliorated in CD22-/-, CD72-/- and CD22-/-/CD72-/- mice compared to WT mice. CONCLUSION These results indicate that CD22 and CD72 likely play crucial roles in skin and lung fibrosis. Moreover, the inhibition of CD22 and CD72 function has potential as a therapeutic approach to SSc.

Abstract
Adhesion molecules may contribute to the development of interstitial lung disease (ILD) and have been proposed as prognostic biomarkers in idiopathic pulmonary fibrosis. Our objective was to determine whether the circulating adhesion molecules soluble intracellular adhesion molecule (sICAM)-1, soluble vascular cell adhesion molecule (sVCAM)-1 and P-selectin are associated with subclinical ILD in community-dwelling adults.The Multi-Ethnic Study of Atherosclerosis enrolled males and females aged 45-84 years from six communities in the United States in 2000-2002. High attenuation areas were defined as the percentage of imaged lung volume with attenuation -600--250 HU on cardiac computed tomography (CT). Interstitial lung abnormalities were visually assessed on full-lung CT. Spirometry was performed on a subset of individuals. ILD hospitalisations and deaths were adjudicated.In fully adjusted analyses, higher levels of sICAM-1, sVCAM-1 and P-selectin were associated with greater high attenuation areas (2.94%, 95% CI 1.80-4.07%; 1.24%, 95% CI 0.14-2.35%; and 1.58%, 95% CI 0.92-2.23%, respectively), and greater rate of ILD hospitalisations (HR 1.36, 95% CI 1.03-1.80; 1.40, 95% CI 1.07-1.85; and 2.03, 95% CI 1.16-3.5, respectively). sICAM-1 was associated with greater prevalence of interstitial lung abnormalities (OR 1.39, 95% CI 1.13-1.71). sICAM-1 and P-selectin were associated with lower forced vital capacity (44 mL, 95% CI 12-76 mL and 29 mL, 95% CI 8-49 mL, respectively). sVCAM-1 and P-selectin were associated with increased risk of ILD death (HR 2.15, 95% CI 1.26-3.64 and 3.61, 95% CI 1.54-8.46, respectively).Higher levels of circulating sICAM-1, sVCAM-1 and P-selectin are independently associated with CT and spirometric measures of subclinical ILD, and increased rate of adjudicated ILD events among community-dwelling adults.

Abstract
Workers chronically exposed to respirable crystalline silica (CS) are susceptible to adverse health effects like silicosis and lung cancer. This study aimed to investigate potential early peripheral biomarkers of inflammation and oxidative stress in miners. The subjects enrolled in this study were occupationally unexposed workers (OUW, n = 29) and workers exposed to crystalline silica (WECS), composed by miners, which were divided into two subgroups: workers without silicosis (WECS I, n = 39) and workers diagnosed with silicosis, retired from work (WECS II, n = 42). The following biomarkers were evaluated: gene expression of L-selectin, CXCL2, CXCL8 (IL-8), HO-1, and p53; malondialdehyde (MDA) plasma levels and non-protein thiol levels in erythrocytes. Additionally, protein expression of L-selectin was evaluated to confirm our previous findings. The results demonstrated that gene expression of L-selectin was decreased in the WECS I group when compared to the OUW group (p < 0.05). Regarding gene expression of CXCL2, CXCL8 (IL-8), HO-1, and p53, significant fold change decreases were observed in workers exposed to CS in relation to unexposed workers (p < 0.05). The results of L-selectin protein expression in lymphocyte surface corroborated with our previous findings; thus, significant downregulation in the WECS groups was observed compared to OUW group (p < 0.05). The MDA was negatively associated with the gene expression of CXCL-2, CXCL8 (IL-8), and p53 (p < 0.05). The participants with silicosis (WECS II) presented significant increased non-protein thiol levels in relation to other groups (p < 0.05). Taken together, our findings may contribute to help the knowledge about the complex mechanisms involved in the silicosis pathogenesis and in the risk of lung cancer development in workers chronically exposed to respirable CS.

Abstract
Valproic acid (VPA), a histone deacetylase (HDAC) inhibitor, is a widely used anticonvulsant drug that is currently undergoing clinical evaluation for anticancer therapy due to its anti-angiogenic potential. Endothelial cells (ECs) can transition into mesenchymal cells and this form of EC plasticity is called endothelial-to-mesenchymal transition (EndMT), which is widely implicated in several pathologies including cancer and organ fibrosis. However, the effect of VPA on EC plasticity and EndMT remains completely unknown. We report herein that VPA-treatment significantly inhibits tube formation, migration, nitric oxide production, proliferation and migration in ECs. A microscopic evaluation revealed, and qPCR, immunofluorescence and immunoblotting data confirmed EndMT-like phenotypic switching as well as an increased expression of pro-fibrotic genes in VPA-treated ECs. Furthermore, our data confirmed important and regulatory role played by TGFβ-signaling in VPA-induced EndMT. Our qPCR array data performed for 84 endothelial genes further supported our findings and demonstrated 28 significantly and differentially regulated genes mainly implicated in angiogenesis, endothelial function, EndMT and fibrosis. We, for the first time report that VPA-treatment associated EndMT contributes to the VPA-associated loss of endothelial function. Our data also suggest that VPA based therapeutics may exacerbate endothelial dysfunction and EndMT-related phenotype in patients undergoing anticonvulsant or anticancer therapy, warranting further investigation.

Abstract
Workers involved in mining activities are exposed to crystalline silica, which leads to constant pulmonary inflammatory reactions and severe oxidative damage, resulting in silicosis. In this work, we aimed to evaluate inflammatory and oxidative stress parameters as potential early biomarkers of effect to assess crystalline silica toxicity in workers who had occupational exposure during mining. We enrolled 38 workers exposed to crystalline silica (WECS), 24 individuals with silicosis (IWS), and 30 occupationally unexposed workers (OUW), a total of 92 participants. The WECS were divided into 2 groups, according to the time of exposure: 19 workers with 1-15 years of occupational exposure (WECS I) and 19 workers with >16 years of occupational exposure (WECS II). The inflammatory parameters assessed were L-selectin, β-2 integrin, and intercellular adhesion molecule-1 (ICAM-1) surface protein expression in lymphocytes and monocytes, complement C3 and C4, high sensitivity C-reactive protein (hsCRP), and adenosine deaminase (ADA) in serum. Plasma levels of malondialdehyde (MDA) and serum levels of vitamin C were determined as biomarkers of oxidative stress. Biochemical and hematological parameters were also investigated. L-selectin surface protein expression was significantly decreased in the WECS II group (p < 0.05), indicating the importance of this immune system component as a potential marker of crystalline-silica-induced toxicity. The MDA levels were significantly increased in the WECS I, WECS II, and IWS groups compared to the OUW group (p < 0.05). Vitamin C levels were decreased, while C3, hsCRP, ADA, and aspartate aminotransferase (AST) levels were increased in the IWS group compared to the OUW group (p < 0.05). Glucose and urea levels were significantly higher in the WECS I, II, and IWS groups compared to the OUW group (p < 0.05). Negative partial association was found between L-selectin and time of exposure (p < 0.001), supporting the relevance of this biomarker evaluation in long-term exposure to crystalline silica. Significant associations were also observed among inflammatory and oxidative stress biomarkers. Therefore, our results demonstrated the relevance of L-selectin as a potential peripheral biomarker for monitoring crystalline silica-induced toxicity in miners after chronic exposure, before silicosis has developed. However, more studies are necessary for better understanding of the use L-selectin as an early biomarker in exposed workers.

Abstract
Background Fibrocytes are implicated in Idiopathic Pulmonary Fibrosis (IPF) pathogenesis and increased proportions in the circulation are associated with poor prognosis. Upon tissue injury, fibrocytes migrate to the affected organ. In IPF patients, circulating fibrocytes are increased especially during exacerbations, however fibrocytes in the lungs have not been examined. Therefore, we sought to evaluate if fibrocytes can be detected in IPF lungs and we compare percentages and phenotypic characteristics of lung fibrocytes with circulating fibrocytes in IPF. Methods First we optimized flow cytometric detection circulating fibrocytes using a unique combination of intra- and extra-cellular markers to establish a solid gating strategy. Next we analyzed lung fibrocytes in single cell suspensions of explanted IPF and control lungs and compared characteristics and numbers with circulating fibrocytes of IPF. Results Using a gating strategy for both circulating and lung fibrocytes, which excludes potentially contaminating cell populations (e.g. neutrophils and different leukocyte subsets), we show that patients with IPF have increased proportions of fibrocytes, not only in the circulation, but also in explanted end-stage IPF lungs. These lung fibrocytes have increased surface expression of HLA-DR, increased intracellular collagen-1 expression, and also altered forward and side scatter characteristics compared with their circulating counterparts. Conclusions These findings demonstrate that lung fibrocytes in IPF patients can be quantified and characterized by flow cytometry. Lung fibrocytes have different characteristics than circulating fibrocytes and represent an intermediate cell population between circulating fibrocytes and lung fibroblast. Therefore, more insight in their phenotype might lead to specific therapeutic targeting in fibrotic lung diseases.

Abstract
To date, phenotyping and disease course prediction in idiopathic pulmonary fibrosis (IPF) primarily relies on lung function measures. Blood biomarkers were recently proposed for diagnostic and outcome prediction in IPF, yet their correlation with lung function and histology remains unclear. Here, we comprehensively assessed biomarkers in liquid biopsies and correlated their abundance with lung function and histology during the onset, progression, and resolution of lung fibrosis, with the aim to more precisely evaluate disease progression in the preclinical model of bleomycin-induced pulmonary fibrosis in vivo. Importantly, the strongest correlation of lung function with histological extent of fibrosis was observed at day 14, whereas lung function was unchanged at days 28 and 56, even when histological assessment showed marked fibrotic lesions. Although matrix metalloproteinase-7 (MMP-7), MMP-9, and PAI-1 were significantly elevated in broncheoalveolar lavage of fibrotic mice, only soluble ICAM-1 (sICAM-1) was elevated in the peripheral blood of fibrotic mice and was strongly correlated with the extent of fibrosis. Importantly, tissue-bound ICAM-1 was also elevated in lung homogenates, with prominent staining in hyperplastic type II alveolar epithelial and endothelial cells. In summary, we show that lung function decline is not a prerequisite for histologically evident fibrosis, particularly during the onset or resolution thereof. Plasma levels of sICAM-1 strongly correlate with the extent of lung fibrosis, and may thus be considered for the assessment of intraindividual therapeutic studies in preclinical studies of pulmonary fibrosis.

Abstract
OBJECTIVE To investigate the role of adhesion molecules in C protein-induced myositis (CIM), a murine model of polymyositis (PM). METHODS CIM was induced in wild-type mice, L-selectin-deficient (L-selectin(-/-) ) mice, intercellular adhesion molecule 1 (ICAM-1)-deficient (ICAM-1(-/-) ) mice, and mice deficient in both L-selectin and ICAM-1 (L-selectin(-/-) ICAM-1(-/-) mice). Myositis severity, inflammatory cell infiltration, and messenger RNA expression in the inflamed muscles were analyzed. The effect of dendritic polyglycerol sulfate, a synthetic inhibitor that suppresses the function of L-selectin and endothelial P-selectin, was also examined. RESULTS L-selectin(-/-) mice and L-selectin(-/-) ICAM-1(-/-) mice developed significantly less severe myositis compared to wild-type mice, while ICAM-1 deficiency did not inhibit the development of myositis. L-selectin(-/-) mice that received wild-type T cells developed myositis. Treatment with dendritic polyglycerol sulfate significantly diminished the severity of myositis in wild-type mice compared to treatment with control. CONCLUSION These data indicate that L-selectin plays a major role in the development of CIM, whereas ICAM-1 plays a lesser role, if any, in the development of CIM. L-selectin-targeted therapy may be a candidate for the treatment of PM.

Abstract
Objective To assess the utility of circulating adhesion molecule levels as a prognostic indicator of disease progression in systemic sclerosis (SSc) patients with early onset disease. Methods Ninety-two Japanese patients with early onset SSc presenting with diffuse skin sclerosis and/or interstitial lung disease were registered in a multicentre, observational study. Concentrations of intercellular adhesion molecule (ICAM) −1, E-selectin, L-selectin, and P-selectin in serum samples from all patients were measured by enzyme-linked immunosorbent asssay (ELISA). In 39 patients, adhesion molecule levels were measured each year for four years. The ability of baseline adhesion molecule levels to predict subsequent progression and severity in clinical and laboratory features were evaluated statistically. Results At their first visit, serum levels of ICAM-1, E-selection, P-selectin were significantly elevated and serum L-selectin levels were significantly reduced in patients with SSc compared with healthy controls. Overall, serum ICAM-1 levels at each time point were significantly inversely associated with the %vital capacity (VC) of the same time and subsequent years by univariate analysis. The initial serum ICAM-1 levels were significantly inversely associated with the %VC at the fourth year by multiple regression analysis. The initial serum P-selectin levels were significantly associated with the health assessment questionnaire disability index (HAQ-DI) at the fourth year by multiple regression analysis. Initial adhesion molecule levels were not significantly associated with other clinical features including skin thickness score. Baseline adhesion molecule levels were not significantly associated with subsequent rate of change of clinical parameters. Conclusion In patients with SSc, serum levels of ICAM-1 and P-selectin may serve as prognostic indicators of respiratory dysfunction and physical disability, respectively. Further longitudinal studies of larger populations are needed to confirm these findings.

ICAM-1 deficiency exacerbates sarcoid-like granulomatosis induced by Propionibacterium acnes through impaired IL-10 production by regulatory T cells. THE AMERICAN JOURNAL OF PATHOLOGY 2013; 183:1731-1739.

Abstract
Propionibacterium acnes has been implicated as one of the suggested causative antigens for sarcoidosis, a systemic granulomatous disease. By injecting heat-killed P. acnes into the dorsal skin of C57BL/6J mice on days 1, 3, 5, and 14, sarcoid-like granulomatosis was induced in skin and lungs of these mice on day 28. To clarify the role of cell adhesion molecules in cutaneous sarcoidosis, we induced sarcoid-like granulomatosis in mice deficient of intercellular adhesion molecule (ICAM)-1, L-selectin, P-selectin, or E-selectin via repeated P. acnes injection. Histopathologic analysis revealed that granuloma formation was aggravated in the skin and lungs of ICAM-1-deficient mice compared with wild-type mice. Within skin granulomas of ICAM-1-deficient mice, P. acnes immunization up-regulated mRNA expression of tumor necrosis factor-α, although it failed to induce IL-10 mRNA expression in contrast to wild-type mice. Infiltration of regulatory T cells into skin granuloma was similar between wild-type mice and ICAM-1-deficient mice. P. acnes immunization induced IL-10 production by CD4(+)CD25(+)Foxp3(+) regulatory T cells in lymph nodes of wild-type mice in vivo, which was absent in regulatory T cells of ICAM-1-deficient mice. Our results indicate that ICAM-1 is imperative for inducing regulatory T cells to produce IL-10 in vivo, which would prevent granuloma formation.

Abstract
Background Coal workers' pneumoconiosis (CWP) is characterized by chronic pulmonary inflammation and fibrotic nodular lesions that usually lead to progressive fibrosis. Inflammation is the first step in the development of CWP. E-selectin, an adhesion molecule, is involved in the development of various inflammatory diseases. Methods We investigated the association between the functional polymorphisms in SELE and the risk of CWP in Han Chinese population. Three polymorphisms (T1880C/rs5355, T1559C/rs5368, A16089G/rs4786) in SELE were genotyped and analyzed in a case-control study with 697 CWP cases and 694 controls. The genotyping was based on the TaqMan method with the ABI 7900HT Real Time PCR system. Results The SELE rs5368 CT genotype was associated with a significantly increased risk of CWP (OR = 1.28, 95% CI = 1.02–1.60, P = 0.03) relative to the CC genotype. The statistical analysis of classification and regression tree (CART) and multifactor dimensionality reduction (MDR) were used to predict the interactions among risk factors of CWP. The MDR analysis found that the best interaction model was the two-factor model that contains pack-years smoked and SELE rs5368 genotypes. For non-smokers, the CART analysis showed an increased risk of CWP for carriers of the SELE rs_5368 variant genotype compared with the common genotype (OR = 1.51; 95% CI = 1.11–2.05, P = 0.0069). Conclusion The results suggest that the T1559C/rs5368 polymorphism and smoking are involved in the susceptibility to CWP. Further studies are warranted to validate these findings.

Abstract
AIM To study the in vivo effects of Quin-C1, a highly specific agonist for formyl peptide receptor 2 (FPR2/ALX), in a mouse model of bleomycin (BLM)-induced lung injury. METHODS Male ICR mice were injected intratracheally with BLM (d 0), and intraperitoneally with Quin-C1 (0.2 mg/d) or vehicle between d 1 and d 28, during which pulmonary inflammation was monitored. A similar regimen was carried out between d 5 and d 28 to differentiate anti-inflammatory from anti-fibrotic effects. During the treatment, leukocyte numbers in bronchoalveolar lavage fluid (BALF) were counted, and FPR2/ALX transcripts, tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), the mouse keratinocyte-derived chemokine (KC), transforming growth factor β1 (TGF-β1) and C-X-C motif chemokine 10 (CXCL10) expression levels in the lung tissue were also measured. Both hydroxyproline content and histological changes were examined on d 28 to assess the severity of lung fibrosis. RESULTS BLM caused a significant increase in expression levels of all the selected cytokines and chemokines, as well as a thickening of the alveolar wall. Treatment with Quin-C1 significantly reduced the neutrophil and lymphocyte counts in BALF, diminished expression of TNF-α, IL-1β, KC, and TGF-β1, and decreased collagen deposition in lung tissue. The treatment also lowered the content of lung hydroxyproline. Quin-C1 did not ameliorate lung fibrosis when the treatment was started 5 d after the BLM challenge, suggesting that the protection may be attributed to its anti-inflammatory effects. Exposure to BLM or BLM plus Quin-C1 did not change the level of FPR2/ALX transcripts (mFpr1, mFpr2, and Lxa4r) in the lung tissue. CONCLUSION The results demonstrate an anti-inflammatory role for Quin-C1 in bleomycin-induced lung injury, which may be further explored for therapeutic applications.

Abstract
BACKGROUND Adrenomedullin (AM), a 52-amino acid ringed-structure peptide with C-terminal amidation, was originally isolated from human pheochromocytoma. AM are widely distributed in various tissues and acts as a local vasoactive hormone in various conditions. METHODS In the present study, we investigated the efficacy of AM on the animal model of bleomycin (BLM)-induced lung injury. Mice were subjected to intratracheal administration of BLM and were assigned to receive AM daily by an intraperitoneal injection of 200 ngr/kg. RESULTS AND DISCUSSION Myeloperoxidase activity, lung histology, immunohistochemical analyses for cytokines and adhesion molecules expression, inducible nitric oxide synthase (iNOS), nitrotyrosine, and poly (ADP-ribose) polymerase (PARP) were performed one week after fibrosis induction. Lung histology and transforming growth factor beta (TGF-β) were performed 14 and 21 days after treatments. After bleomycin administration, AM-treated mice exhibited a reduced degree of lung damage and inflammation compared with BLM-treated mice, as shown by the reduction of (1) myeloperoxidase activity (MPO), (2) cytokines and adhesion molecules expression, (3) nitric oxide synthase expression, (4) the nitration of tyrosine residues, (5) poly (ADP-ribose) (PAR) formation, a product of the nuclear enzyme poly (ADP-ribose) polymerase (PARP) (6) transforming growth factor beta (TGF-β) (7)and the degree of lung injury. CONCLUSIONS Our results indicate that AM administration is able to prevent bleomycin induced lung injury through the down regulation of proinflammatory factors.

Abstract
Mice s.c. injected with bleomycin, an experimental model for human systemic sclerosis, develop skin and lung fibrosis, which is mediated by inflammatory cell infiltration. This process is highly regulated by multiple adhesion molecules and does not require Ag sensitization. To assess the role of adhesion molecules in this pathogenetic process, bleomycin-induced fibrosis was examined in mice lacking adhesion molecules. L-selectin and/or ICAM-1 deficiency inhibited skin and lung fibrosis with decreased Th2 and Th17 cytokines and increased Th1 cytokines. In contrast, P-selectin deficiency, E-selectin deficiency with or without P-selectin blockade, or P-selectin glycoprotein ligand 1 (PSGL-1) deficiency augmented the fibrosis in parallel with increased Th2 and Th17 cytokines and decreased Th1 cytokines. Furthermore, loss of L-selectin and/or ICAM-1 reduced Th2 and Th17 cell numbers in bronchoalveolar lavage fluid, whereas loss of P-selectin, E-selectin, or PSGL-1 reduced Th1 cell numbers. Moreover, Th1 cells exhibited higher PSGL-1 expression and lower expression of LFA-1, a ligand for ICAM-1, whereas Th2 and Th17 cells showed higher LFA-1 and lower PSGL-1 expression. This study suggests that L-selectin and ICAM-1 regulate Th2 and Th17 cell accumulation into the skin and lung, leading to the development of fibrosis, and that P-selectin, E-selectin, and PSGL-1 regulate Th1 cell infiltration, resulting in the inhibition of fibrosis.

Abstract
Bleomycin (BLM)-induced lung injury consists of excessive inflammatory cell infiltration and fibrosis. IS-741 has been reported to be an anti-inflammatory drug through an inhibitory action on cell adhesion. In this study we investigated whether IS-741 could inhibit the progression of pulmonary fibrosis through inflammatory cell infiltration. Lung injury was induced in female C57BL/6 mice by intratracheal instillation of BLM. IS-741 was administered daily intraperitoneally. The hydroxyproline content and fluid content in the lung on Day 28 were significantly lower in the IS-741-treated mice. The histological degree of lung injury or fibrosis was reduced in IS-741-treated mice. Administration of IS-741 caused significant reduction in the absolute number of total cells, monocyte chemoattractant protein (MCP)-1, and cysteinyl leukotriene (cysLTs) levels in bronchoalveolar lavage fluid on Day 7. Furthermore, the hydroxyproline content was significantly lower in IS-741-treated mice even though IS-741 was started on Day 14 after BLM instillation. Treatment with IS-741 had an inhibitory effect on BLM-induced lung injury and fibrosis via the repression of MCP-1 or cysLTs in this murine experimental model.

Abstract
Taurine has been shown to protect against lung injury induced by various oxidants including ozone, nitrogen dioxide, amiodarone, and paraquat and to protect against bleomycin-induced lung injury in combination with niacin. In this study, Spraque-Dawley rats were treated with 5% taurine in the drinking water for 10 days prior to bleomycin instillation. Fibrosis in the rats pretreated with taurine (BT) was absent, along with fewer inflammatory infiltrates compared to the untreated rats (BW). A significant decrease in the number of PMNs and a decrease in hydroxyproline levels were found in the bronchoalveolar lavage fluid in the BT group compared to the BW group. By immunohistochemical staining, inducible nitric oxide synthase was evident in the lungs of bleomycin-treated rats, and minimal when rats were treated with taurine. Tumor necrosis factor-alpha (TNF-alpha) as measured by immunohistochemical staining, was present in lungs of both taurine-treated and untreated rats, but was more abundant in the BW group compared to the BT group. In addition, decreased ICAM presentation was detected by EM immunogold staining in the BT group compared to the BW group. These data demonstrate that rats pretreated with 5% taurine in their drinking water prior to bleomycin instillation are protected from fibrosis, inflammatory infiltrates, as well as nitric oxide and TNF-alpha production, which are hallmarks of bleomycin lung injury.

Abstract
OBJECTIVE The contribution of CD19 and B lymphocytes to pulmonary fibrosis is controversial. The aim of this study was to address the role of CD19 during the development of pulmonary fibrosis. METHODS Mice lacking or overexpressing the B cell surface molecule CD19, which is known as a positive regulator of B cell activation, were used in a model of bleomycin-induced pulmonary fibrosis. Ten or sixteen days after intratracheal injection of bleomycin, lung sections from mice were evaluated by histologic analysis. Seven days after instillation, the total leukocyte count and the number of B cells in bronchoalveolar lavage fluid (BALF) were determined, using a hemocytometer and flow cytometry. Bleomycin was also administered into selectin-deficient or intercellular adhesion molecule 1-deficient mouse strains. The level of CXCR3 expression on B cells was determined by flow cytometry. RESULTS CD19 deficiency significantly reduced susceptibility to intratracheal bleomycin challenge on day 16, while CD19 overexpression augmented fibrosis even on day 10. Furthermore, the survival rate and number of B cells in BALF also correlated with CD19 expression levels. The accumulation of B cells in BALF was dependent on CD19 levels, whereas there was no association with the levels of selectins or intercellular adhesion molecule 1. Additionally, CXCR3 was up-regulated in BALF B cells, while it was rarely expressed on circulating B cells. Furthermore, CD19 signaling facilitated B cell CXCR3 up-regulation in response to stimulation in vitro. CONCLUSION These results suggest that CD19 signaling is associated with the development of pulmonary fibrosis by controlling B cell infiltration into lung tissue, which may be associated with CXCR3 up-regulation.

Abstract
Organ toxicity induced by chemotherapeutic drugs is a serious obstacle in the effective treatment of patients suffering from cancer and autoimmune disease. A strong association exists between pulmonary toxicity, particularly fibrosis, and chemotherapeutic drugs. Attempts have been made to identify compounds capable of suppressing fibrosis. In addition to its erythropoietic activity, erythropoietin (EPO) has been shown to have effects on nonhemopoietic cells. Therefore, we postulated that EPO may exert beneficial effects on lung tissue during chemotherapy. To test our hypothesis, we investigated pulmonary changes caused by bleomycin, a fibrosis-inducing agent, in animals treated with the drug alone and in combination with EPO. Fibrosis, cellular alterations and structural changes were assayed by blind analysis of the lung sections. A 6-fold decrease in the number of prominent endothelial cells--suspected to be indicative of cellular activation and inflammatory response--was observed in lung sections derived from mice treated with bleomycin and EPO compared to animals injected with bleomycin alone (p < 0.008). Additionally, there was twice the number of ICAM1-positive endothelial cells in animals treated with bleomycin alone compared with the number in the bleomycin and EPO-treated group (p < 0.05). Alveolar mononuclear phagocytic hyperplasia was reduced by as much as 100% in animals treated with bleomycin and EPO compared to animals treated with bleomycin alone (p < 0.03). Finally, a 5-fold decrease in interstitial fibrosis was observed in lung sections obtained from animals treated with bleomycin and EPO (p < 0.02). We conclude that EPO can ameliorate drug-induced fibrosis and endothelial damage caused by chemotherapeutic agents.

Abstract
Although mouse models of inflammatory skin diseases such as psoriasis and atopic dermatitis fail to completely phenocopy disease in humans, they provide invaluable tools to examine the molecular and cellular mechanisms responsible for the epidermal hyperplasia, inflammation, and excess angiogenesis observed in human disease. We have previously characterized a tyrosine kinase with immunoglobin-like and epidermal growth factor-like domain-2 (Tie-2) transgenic mouse model of an inflammatory skin disease exhibiting these features. More specifically, we demonstrated that the inflammatory component consisted of increased infiltration of CD3-positive T lymphocytes and mast cells in the skin. Here, we further characterize the inflammatory component in the blood and skin of Tie-2 transgenic mice at cellular and molecular levels. We observed increased numbers of CD3-positive T lymphocytes in the blood and increased infiltration of eosinophils in the skin. Furthermore, we characterized cytokine protein and gene expression in the blood and skin, respectively, and observed the deregulated expression of cytokines associated with Th1 and eosinophil immune responses. Interestingly, treatment of Tie-2 transgenic mice with anti-CD4 antibody appeared to resolve aspects of inflammation but did not resolve epidermal hyperplasia, suggesting an important role for eosinophils in mediating the inflammatory skin disease observed in Tie-2 transgenic mice.

Abstract
BACKGROUND CONTEXT Data from studies in other diseases state implicate cellular adhesion molecules as mediators of fibrosis and scarring. We sought to explore and assess the effect of using monoclonal antibodies against intercellular adhesion molecule-1 (ICAM-1) and its ligand CD-18 to decrease epidural fibrosis in an animal spinal surgery model. PURPOSE We hypothesize that use of antiadhesion molecules (anti-ICAM-1 and anti-CD-18) decreases epidural fibrosis in rats after spinal surgery compared with nontreated group and monoclonal anti human immunoglobulin (Ig)G group. STUDY DESIGN Experimental animal spine surgery (laminectomy) protocol with application of antiadhesion molecules (anti-ICAM-1 and anti-CD-18 group as a specific monoclonal antibody) to surgical site in test group compared with monoclonal antihuman IgG group (as a nonspecific monoclonal antibody) and nontreated group. METHODS Thirty Sprague Dawley male or female rats weighing 175 to 250 g were used randomly for three groups (nontreated, anti-ICAM-1 and anti-CD-18, monoclonal antihuman IgG). Laminectomy was performed at level L4 in all animal groups. After injection of materials (except nontreated group), the surgical sites were closed in layers. Three weeks later, all rats were killed. Twenty-seven rats were available for histological analysis. The histological sections were evaluated for fibroblast numbers of fibrous tissue within the laminectomy side, adhesion degree between dura mater and fibrous tissue, and new bone formation in the laminectomy region. RESULTS Comparing the fibroblast numbers in fibrous tissue within groups, the number of fibroblasts were significantly less in anti-ICAM-1 and anti-CD-18 group than nontreated group (p=.037). The number of fibroblasts of monoclonal anti human IgG group was not significantly different from anti-ICAM-1 and anti-CD-18 (p=.608) and the nontreated group (p=.508). In the anti-ICAM-1 and anti-CD-18 applied group, adhesion degree was found significantly less than monoclonal antihuman IgG (p=.036) and nontreated group (p=.036) statistically. There were no significant difference between the monoclonal antihuman IgG group and the nontreated group about adhesion degree (p=.645). CONCLUSIONS Therapy that targets ICAM-1 could be valuable in the management of epidural fibrosis. Blocking the function of ICAM-1 may provide cellular protection against epidural fibrosis and also it may serve as an important component in this period, acting to promote leukocyte migration across epidural area after laminectomy.

Abstract
The healing of a skin wound is a complex process involving many cell lineages. In adult tissues, repair is always accompanied by a robust inflammatory response, which is necessary to counter the potential for infection at any site where the skin barrier is breached. Unlike embryonic tissues that can repair perfectly without a remnant scar at the wound site, adult tissue repair always leads to formation of a fibrotic scar where the wound has healed. In recent years, it has become clear that the wound inflammatory response may be, at least in part, responsible for fibrosis at sites of tissue repair. In this review, we consider the beneficial vs the detrimental functions of inflammatory cells during the repair response and compare data from other tissues, the lung, and liver, where fibrosis and its resolution may be related to a damage-triggered inflammatory response. We also consider how it may be possible to molecularly disentangle the potentially good from the bad influences of inflammatory cells during tissue repair and how fundamental studies in inflammatory cell biology may prove the way forward for development of drug targets in this respect.

Abstract
OBJECTIVES Chronic pancreatitis consists of excessive leukocyte infiltration and fibrosis. IS-741 has been reported to be an antiinflammatory drug through an inhibitory action on cell adhesion. In this study, we investigated whether IS-741 could inhibit the progression of pancreatic fibrosis through monocyte infiltration. Moreover, we investigated the effect of IS-741 on rat pancreatic stellate cells (PSCs). METHODS Chronic pancreatitis was induced by dibutyltin dichloride in rats. From days 7 to 28 after dibutyltin dichloride application, IS-741 or distilled water was administered. At days 14 and 28, histological [hematoxylin-eosin stain and immunostain for ED1 and [alpha] smooth muscle actin (alpha-SMA)] and biochemical evaluations (intrapancreatic amylase, protein, cytokines, chemokines, and alpha-SMA) were performed. In vitro, rat PSCs were incubated with cytokine, chemokine, and growth factor simultaneously with IS-741, and their proliferation and activation were examined. RESULTS Histologically, IS-741 inhibited pancreatic fibrosis and decreased the number of ED1- and [alpha]-SMA-positive cells. The intrapancreatic expression of cytokines, chemokine, and [alpha]-SMA were also decreased. In vitro, IS-741 has no direct effect on the proliferation, alpha-SMA expression, and collagen synthesis of PSCs. CONCLUSIONS These results suggest that IS-741 suppressed macrophage infiltration and subsequent pancreatic fibrosis and that the infiltration of monocytes into pancreas is essential for pancreatic fibrosis.

Abstract
Pulmonary fibrosis is characterized by excessive deposition of extracellular matrix in interstitium resulting in respiratory failure associated with inflammation showing mainly neutrophil (PMN) recruitment. The turn over of extracellular matrix is partially regulated by proteases such as metalloproteinases (MMPs) and their inhibitors (TIMPs). We investigated the impact of PMN depletion on the MMP/TIMP-1 imbalance and the development of fibrosis in mice induced by bleomycin (0.3 mg/mouse). Administration of 200 microL of rabbit anti-mouse PMN antibody i.p. blunted the neutrophil influx detected in BAL and in whole blood one day after bleomycin administration. At day(14), hydroxyproline content was increased both in anti-PMN treated and control mice, without any difference between groups. At day one, bleomycin elicited a raise in pro-MMP-9 level in BAL that was significantly attenuated in anti-PMN depleted mice, whereas TIMP-1 and MMP-2 release were similar in both groups at day(1) and day(14). Higher RNA levels were observed in PMN-treated mice at day(1) for MMP-9 and MMP-2 and at day(14) for MMP-2 only. At day(14), bleomycin elicited a raise of TIMP-1 protein and RNA levels regardless of anti-PMN treatment, whereas MMP-9 returned to basal level. Bleomycin enhanced MMP-8 level in BAL at day(14) only for the control group. The amount of MMP-8 was more important in BAL from anti-PMN treated mice than in control mice at day(1) and day(14). PMN-depletion and the associated modifications in pro-MMP-9/TIMP-1 imbalance in lung during the early inflammatory phase do not alter susceptibility to bleomycin-induced pulmonary fibrosis.

Abstract
Pulmonary fibrosis is characterized by the excessive deposition of extracellular matrix in the interstitium, resulting in respiratory failure. The role of remodeling mediators such as metalloproteinases (MMPs) and their inhibitors (TIMPs) in the fibrogenic process remains misunderstood. We investigated MMP-9, MMP-2, TIMP-1, TIMP-2 and TIMP-3 in the fibrotic response to bleomycin of fibrosis prone C57BL/6J and fibrosis resistant BALB/c mice. Mice were administered with 0.1 mg bleomycin by intranasal administration. Either 24 h or 14 days after, the mice were anesthetized and underwent either bronchoalveolear lavage (BAL) or lung removal. Collagen deposition in lung tissue was determined by hydroxyproline measurement, MMP activity was analyzed by zymography, and other mediators were analyzed by ELISA. TIMP-1 was localized in lung sections by immunohistochemistry and real time PCR was performed to gene expression in lung. Non parametric Mann-Whitney and Spearman tests were used for statistical analysis. Fourteen days after bleomycin administration, hydroxyproline assay and histological study revealed that BALB/c mice developed significantly less fibrosis compared to C57BL/6J mice. At day 1, bleomycin enhanced TIMP-1, MMP-2 and MMP-9 protein levels in BALF, and induced corresponding genes in lung tissue of both strains. The rise of Timp-1, Mmp-9 and Mmp-2 gene levels were significantly stronger in lungs of C57BL/6J, whereas gelatinase activities of MMP-2 and MMP-9 were similar. Immunohistochemistry revealed that TIMP-1 macrophages and epithelial cells were prominent TIMP-1 producers in both strains. At day 14, neither MMP-2 nor MMP-9 levels exhibited strain-dependent protein level or gene expression, although TIMP-1 was strongly associated with fibrosis. Interestingly, bleomycin induced neither Timp-2 nor Timp-3 in lung tissue at any time of the study. The present study shows that early altered regulation of TIMP-1 following bleomycin administration may be involved in bleomycin-induced pulmonary fibrosis.

Abstract
The development of bleomycin-induced lung injury, which is a model of pulmonary fibrosis, results from inflammatory cell infiltration, a process highly regulated by the expression of multiple adhesion molecules. Therefore, bleomycin-induced lung fibrosis was examined in E-selectin-/- mice, P-selectin-/- mice, and E-selectin-/- mice treated with anti-P-selectin monoclonal antibody (mAb) in comparison of wild-type mice. E-selectin-/- mice treated with anti-P-selectin mAb exhibited augmented lung fibrosis histologically, increased lung collagen deposition, and increased mortality compared to wild-type mice. Furthermore, lung interferon-gamma mRNA expression decreased in E-selectin-/- mice treated with anti-P-selectin mAb relative to wild-type mice, while tumor necrosis factor-alpha and interleukin-6 mRNA expression increased in these mice. Similar changes were observed in E-selectin-/- mice, albeit to a lesser extent than those treated with anti-P-selectin mAb. Remarkably, flow cytometric analysis revealed that the frequency of interferon-gamma-producing natural killer T (NKT) cells in the bronchoalveolar lavage was decreased in E-selectin-/- mice and E-selectin-/- mice treated with anti-P-selectin mAb compared with wild-type mice. Moreover, the majority of NKT cells expressed high levels of CXCR3, suggesting that NKT cell infiltration is also dependent on CXCR3 expression. These results suggest that E- and P-selectins synergistically inhibit lung fibrosis by promoting the recruitment of NKT cells.

Abstract
Malignant melanoma is often accompanied by a host response of inflammatory cell infiltration that is highly regulated by multiple adhesion molecules. To assess the role of adhesion molecules, including L-selectin and intercellular adhesion molecule-1 (ICAM-1), in this process, subcutaneous primary growth and metastasis to the lung of B16 melanoma cells not expressing L-selectin, ICAM-1 or their ligands were examined in mice lacking L-selectin, ICAM-1 or both. Primary subcutaneous growth of B16 melanoma was augmented by loss of L-selectin, ICAM-1 or both, while pulmonary metastasis was enhanced by the loss of L-selectin or combined loss of L-selectin and ICAM-1. In both situations, the combined loss of L-selectin and ICAM-1 exhibited the greatest effect. This enhancement was associated generally with a reduced accumulation of natural killer (NK) cells, CD4+ T cells and CD8+ T cells and also with a diminished release of interferon (IFN)-gamma and tumour necrosis factor (TNF)-alpha but not interleukin (IL)-6. Cytotoxicity against melanoma was not defective by the absence of ICAM-1, L-selectin or both, suggesting that the enhancement of tumour growth and metastasis caused by the loss of adhesion molecules results from an impaired migration of effector cells into the tissue rather than from a suppression of the cytotoxic response. The results indicate that L-selectin and ICAM-1 contribute co-operatively to the anti-tumour reaction by regulating lymphocyte infiltration to the tumour.

Abstract
The balance between prostacyclin and thromboxane A2 (TXA2) plays an important role in pulmonary homeostasis. However, little information is available regarding the therapeutic potency of these prostanoids for pulmonary fibrosis. We have recently developed ONO-1301, a novel long-acting prostacyclin agonist with thromboxane synthase inhibitory activity. Thus we investigated whether repeated administration of ONO-1301 attenuates bleomycin-induced pulmonary fibrosis in mice. After intratracheal injection of bleomycin or saline, mice were randomized to receive repeated subcutaneous administration of ONO-1301 or vehicle. Bronchoalveolar lavage (BAL) and histological analyses were performed at 3, 7, and 14 days after bleomycin injection. In vitro studies using mouse lung fibroblasts were also performed. ONO-1301 significantly attenuated the development of bleomycin-induced pulmonary fibrosis, as indicated by significant decreases in Ashcroft score and lung hydroxyproline content. ONO-1301 significantly reduced total cell count, neutrophil count, and total protein level in BAL fluid in association with a marked reduction of TXB2. A single administration of ONO-1301 significantly increased plasma cAMP level for >2 h. In vitro, ONO-1301 and a cAMP analog dose-dependently reduced cell proliferation in mouse lung fibroblasts. The reduction in cell proliferation by ONO-1301 was attenuated by a protein kinase A (PKA) inhibitor. Furthermore, bleomycin mice treated with ONO-1301 had a significantly higher survival rate than those given vehicle. These results suggest that repeated administration of ONO-1301 attenuates the development of bleomycin-induced pulmonary fibrosis and improves survival in bleomycin mice, at least in part by inhibition of TXA2 synthesis and activation of the cAMP/PKA pathway.

Abstract
Vascular endothelium is a continuous cell layer lining the cardiovascular system and serves as an interface between blood and the vascular wall tissue. Although the basic morphology of endothelial cells is similar in blood vessels of different organs and tissues, there is a great heterogeneity in endothelial cell types based on structural, metabolic, and developmental differences within each organ, particularly in the pulmonary vasculature. Current data about the usage of different markers for the immunohistochemical detection of endothelial cells in lung tissue are summarized, and functional aspects of caveolin expression after lung injury and in pulmonary hypertension are discussed.

Abstract
BACKGROUND Idiopathic pneumonia syndrome (IPS) is a frequently fatal complication of allogeneic bone marrow transplantation (BMT). IPS is associated with elevated bronchoalveolar lavage (BAL) fluid levels of tumor necrosis factor-alpha and lipopolysaccharide, both of which are potent activators of endothelial cells (ECs). EC expression of the adhesion molecule CD54 (intercellular adhesion molecule [ICAM]-1) has been shown to be a major regulator of pulmonary inflammation in various experimental models. METHODS Using a well-established murine BMT system in which lung injury and graft-versus-host disease (GvHD) are induced by minor histocompatibility antigenic differences between donor and host, the RNase Protection Assay, mice deficient in ICAM-1 expression, and a monoclonal blocking antibody to ICAM, we evaluated the role of the pulmonary vascular expression of CD54 in the development of IPS. RESULTS Enhanced pulmonary vascular expression of ICAM-1 coincided with the development of IPS. When ICAM-1 -/- mice were used as allogeneic BMT recipients, IPS severity (measured by lung histopathology, BAL cellularity, and cytokine expression) was significantly reduced compared with wild-type controls. Similar results were also observed when wild-type recipients were treated with a monoclonal blocking antibody to ICAM-1. Surprisingly, ICAM-1 had differential effects on leukocyte infiltration into GvHD target organs; ICAM-1 deficiency had no impact on intestinal histopathology, whereas ICAM-1-/- BMT recipients had significantly enhanced hepatic injury. CONCLUSIONS These data demonstrate that although the expression of ICAM-1 is critical for the development of IPS, different mechanisms of leukocyte recruitment are operative in other GvHD target organs.

Abstract
The cytostatic drug bleomycin (BLM) induces pulmonary fibrosis as its main side effect. Fibroblasts in fibrotic foci are the main cellular source for extracellular matrix accumulation that typifies fibrosis. In vitro studies demonstrated the ability of cytotoxic drugs to induce terminal differentiation of fibroblasts. These postmitotic cells are very active in regard to production of collagens. The present study was addressed to investigate the potential of BLM to induce terminal differentiation of rat lung fibroblasts in vitro and the consequences for collagen production and for the expression and activity of the collagen modifying enzyme prolyl 4-hydroxylase (P4H). The BLM effects were compared with those of mitomycin C (MMC), another cytotoxic agent with known potential for initiation of postmitotic differentiation of fibrobasts. BLM induced postmitotic differentiation of rat lung fibroblasts. The capacity of the cells to form clones was diminished by BLM or MMC in a concentration dependent manner. Both drugs initiated the formation of an increasing number of postmitotic cell clones. The postmitotic differentiation was accompanied by an increase in total collagen production by the cells. Administration of BLM to cultures of lung fibroblasts at concentrations of 1 or 10 mU/ml resulted in an increase of the collagen amount to about the 1.5-fold and 1.6-fold of controls, respectively. Treatment of fibroblasts with MMC elevated the collagen level to about the 2-fold. P4H activity and P4Halpha mRNA levels in cells exposed to BLM or MMC were found to be increased. We conclude that terminally differentiated fibroblasts might be part of the heterogeneous population of fibroblast-like cells in fibrotic foci responsible for the increased production of collagen during the fibrotic phase of the development of pulmonary fibrosis.

Abstract
In order to test the serum levels of ICAM-1, ICAM-2 and ICAM-3 in patients with idiopathic pulmonary fibrosis (IPF), twenty patients with IPF and eleven with secondary interstitial fibrosis (SIF), as well as forty healthy volunteers (HV) were studied. Serum intracellular adhesion molecules (ICAM) 1, 2 and 3 were assessed by ELISA. Functional respiratory tests, which included spirometry and lung diffusing capacity were simultaneously performed. Median values of serum ICAM-1 and ICAM-2 were higher in the patients' than in the healthy volunteers' (HV) group: IPF group: 946.60 ng/ml and 400.14 ng/ml; SIF group: 901.58 ng/ml and 378.27 ng/ml; HV group: 308.40 ng/ml and 217.55 ng/ml, respectively (p<0.05). ICAM-3 serum levels were equal between the three groups. ICAM-2 negatively correlated to DLCO values. (p<0.005). It can be concluded that ICAM 1 and 2 are elevated in the sera of patients with pulmonary fibrosis. ICAM-2 might be associated with a more impaired clinical status.

Abstract
Mice develop changes in sleep during the nonspecific immune response that occurs during the initial few days after inoculation with influenza virus. T lymphocytes, neutrophils, macrophages, and natural killer (NK) cells all participate in the early host response to influenza infection. All of these cell types are potential sources of endogenous substances that modulate sleep, but the contributory role of each cell type to the alteration of somnolence during infection has not been determined. To investigate which cell types contribute to the sleep enhancement that develops during influenza infection in mice, the sleep patterns of C57BL/6J mice with perturbations of particular facets of host immune response capabilities were assessed before and after influenza infection. Targeted mutation of the gene Ccl3 (macrophage inflammatory protein 1 alpha) prevented development of the dark phase sleep enhancement that is characteristic of C57BL/6J mice after influenza infection. Other experimental treatments that impair macrophage or monocyte function also produced significant (administration of pentoxifylline or CNI-1493) or marginally significant (deletion of the interferon-gamma gene or intranasal administration of carrageenan) changes in influenza-induced sleep enhancement in C57BL/6J mice. In contrast, functional impairments of NK cells, neutrophils, and T lymphocytes did not significantly influence sleep responses. These data therefore support a contributory role for macrophages, but not for NK cells, neutrophils, and T lymphocytes, in eliciting the sleep response typical of influenza-infected C57BL/6J mice.

Abstract
To investigate the pathomechanisms of bleomycin-induced early inflammation of lung parenchyma which is known to result in pulmonary fibrosis, we examined the in vitro effect of bleomycin (BLM) on primary human pulmonary microvascular endothelial cells (HMVEC-L). After incubation of microvascular endothelial cells with BLM we detected an induced phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK) by immunoblotting. Further, after BLM-exposure an increased concentration of interleukin-8 (IL-8) in culture supernatant and an increased expression of intercellular adhesion molecule-1 (ICAM-1, CD54) on the cell surface have been observed. Real-time PCR revealed up-regulated mRNA expression levels of both, IL-8 and ICAM-1 after treatment with BLM. Finally, pre-treatment with a selective p38 MAPK-inhibitor, SB 203580, potently reduced the BLM-induced up-regulation of IL-8 expression but did not show any effect on expression of ICAM-1. These results demonstrate that BLM induces the expression of pro-inflammatory molecules in the pulmonary microvascular endothelium, which thereby may actively contribute to the development of early inflammation and later fibrosis of the lung. Furthermore, investigating the effect of an inhibitor of p38 MAPK the data indicate the involvement of p38 MAPK-dependent as well as p38 MAPK-independent mechanisms in the effects of BLM on the pulmonary microvasculature.

Abstract
Hapten sensitization through UV-exposed skin induces systemic immune suppression, which is experimentally demonstrated by inhibition of contact hypersensitivity (CHS). Although this UV-induced effect has been shown to be mediated by inhibition of the afferent phase of the CHS, the UV effects on the efferent (elicitation) phase remain unknown. In this study, UV effects on endothelial ICAM-1 expression at elicitation sites were first examined. Mice were sensitized by hapten application onto UV-exposed back skin, and ears were challenged 5 days later. ICAM-1 up-regulation at nonirradiated elicitation sites following hapten challenge was eliminated by UV exposure on sensitization sites distant from elicitation sites. To assess whether loss of the ICAM-1 up-regulation at elicitation sites contributed to UV-induced immunosuppression, we examined CHS responses in UV-exposed ICAM-1-deficient (ICAM-1(-/-)) mice that genetically lacked the ICAM-1 up-regulation. ICAM-1(-/-) mice exhibited reduced CHS responses without UV exposure, but UV exposure did not further reduce CHS responses in ICAM-1(-/-) mice. Furthermore, ICAM-1 deficiency did not affect the afferent limb, because ICAM-1(-/-) mice had normal generation of hapten-specific suppressor and effector T cells. This UV-induced immunosuppression was associated with a lack of TNF-alpha production after Ag challenge at elicitation sites. Local TNF-alpha injection before elicitation abrogated the UV-induced CHS inhibition with increased endothelial ICAM-1 expression. TNF-alpha production at elicitation sites was down-regulated by IL-10, a possible mediator produced by hapten-specific suppressor T cells that are generated by UV exposure. These results indicate that UV exposure inhibits CHS by abrogating up-regulation of endothelial ICAM-1 expression after Ag challenge at elicitation sites.
