The major histocompatibility complex (MHC) class II transactivator (MHC2TA) is known as a master regulator for expression of MHC class II molecules. In the present study, we investigated the influence on the risk for sarcoidosis of two variants of the MHC2TA gene, selected from previous association studies of inflammatory diseases. Seven hundred and twentyâeight sarcoidosis [...]
M[Phi] and DC are key elements in the control of tissue homeostasis and response to insult. In this work, we demonstrate that M[Phi] and DC are the major producers of the phenylalanine catabolizing enzyme IL-4-induced gene 1 (IL4I1) under inflammatory conditions. IL4I1 was first described in B cells, which indeed can produce IL4I1 in vitro, [...]
Abstract CHI3L1 gene encodes for a glycoprotein (HC-gp39 or YKL40) secreted by synovial fibroblasts, macrophages, neutrophil granulocytes and chondrocytes. Its expression is under the control of NF-kB. It is regarded as an acute phase protein, and its levels are significantly elevated in rheumatic diseases. Furthermore, HC-gp39 has been shown to be recognized by autoreactive T cells [...]
