Scleroderma fibroblasts exhibit numerous phenotypic differences when compared with healthy skin fibroblasts. Some of these differences, in particular overexpression of collagen type I and other extracellular matrix proteins, parallel the effect of transforming growth factor-beta (TGF-beta) on dermal fibroblasts, suggesting that the scleroderma fibroblast(More)
IgA Fc receptors (Fc alphaR) can mediate a variety of inflammatory responses. It has been demonstrated that the FcRgamma subunit is critical in mediating signaling through Fc alphaR. We show that aggregation of Fc alphaR on U937 cells and blood neutrophils results in tyrosine phosphorylation of several intracellular proteins, including the FcR gamma(More)
Neutrophils play a crucial role in host defence. In response to a variety of inflammatory stimulation, they form neutrophil extracellular traps (NETs). NETs are extracellular structures composed of chromatin fibers decorated with antimicrobial proteins and developing studies indicate that NETs contribute to extracellular microbial killing. While the(More)
