The cellular and physiologic mechanisms that regulate the resolution of inflammation remain poorly defined despite their widespread importance in improving inflammatory disease outcomes. We studied the resolution of two cardinal signs of inflammation-pain and swelling-by investigating molecular mechanisms that regulate neural and lymphatic vessel remodeling during the resolution of corneal inflammation. A mouse model of corneal inflammation and wound recovery was developed to study this process in vivo. Administration of nerve growth factor (NGF) increased pain sensation and inhibited neural remodeling and lymphatic vessel regression processes during wound recovery. A complementary in vivo approach, the corneal micropocket assay, revealed that …

INTRODUCTION: Alcohol-induced neuroinflammation is mediated by pro-inflammatory cytokines and chemokines including tumor necrosis factor-alpha (TNFalpha), monocyte chemotactic protein-1 (MCP1) and interleukin-1-beta (IL-1beta). Toll-like receptor-4 (TLR4) pathway induced nuclear factor-kappaB (NF-kappaB) activation is involved in the pathogenesis of alcohol-induced neuroinflammation. Inflammation is a highly regulated process. Recent studies suggest that microRNAs (miRNAs) play crucial role in fine tuning gene expression and miR-155 is a major regulator of inflammation in immune cells after TLR stimulation. AIM: To evaluate the role of miR-155 in the pathogenesis of alcohol-induced neuroinflammation. METHODS: Wild type (WT), miR-155- and TLR4-knockout (KO) mice received 5% ethanol-containing or isocaloric …

CASPASE-12 (CASP12) has a downregulatory function during infection and thus may protect against inflammatory disease. We investigated the distribution of CASP12 alleles (#rs497116) in African-Americans (AA) with rheumatoid arthritis (RA). CASP12 alleles were genotyped in 953 RA patients and 342 controls. Statistical analyses comparing genotype groups were performed using Kruskal–Wallis non-parametric ANOVA with Mann–Whitney U tests and chi-square tests. There was no significant difference in the overall distribution of CASP12 genotypes within AA with RA, but CASP12 homozygous patients had lower baseline joint-narrowing scores. CASP12 homozygosity appears to be a subtle protective factor for some aspects of RA in AA …

Heme oxygenase-1(HO-1) is an enzyme that plays a very important role in the resolution of inflammation. HO-1-based therapies are effective in a number of disease conditions. However, HO-1 also increases tumor growth, angiogenesis, metastasis and chemoresistance. Matrix metalloproteinase-3 (MMP-3) is an enzyme involved in physiological and pathophysiological tissue remodeling. Unbalanced expression of MMPs is a key feature of connective tissue destruction in chronic inflammatory conditions. Previously shown in this laboratory, the HO-1 inducer, hemin, increased MMP-3 mRNA expression in some HGF cultures. To assess whether HO-1 and/or its products regulate expression of MMP-3 in human fibroblasts, the effect of HO-1 …
