https://www.selleckchem.com/ The scavenger receptor CD163 is highly expressed in macrophages in sites of chronic inflammation where it has a not yet defined role. Here we have investigated development of collagen-induced arthritis (CIA) and collagen antibody-induced arthritis (CAIA) in CD163-deficient C57BL/6 mice. Compared to wild-type mice, the CIA in CD163-deficient mice had a several-fold higher arthritis score with early onset, prolonged disease and strongly enhanced progression. Further, the serum anti-collagen antibody isotypes as well as the cytokine profiles and T cell markers in the inflamed joints revealed that CD163-deficient mice after 52 days had a predominant Th2 response in opposition to a predominant Th1 response in CD163+/+ mice. Less difference in disease severity between the CD163+/+ and CD163-/- mice was seen in the CAIA model that to a large extent induces arthritis independently of T-cell response and endogenous Th1/Th2 balance. In conclusion, the present set of data points on a novel strong anti-inflammatory role of CD163.TGFβ signalling has key roles in cancer progression most carcinoma cells have inactivated their epithelial antiproliferative response and benefit from increased TGFβ expression and autocrine TGFβ signalling through effects on gene expression, release of immunosuppressive cytokines and epithelial plasticity. As a result, TGFβ enables cancer cell invasion and dissemination, stem cell properties and therapeutic resistance. TGFβ released by cancer cells, stromal fibroblasts and other cells in the tumour microenvironment further promotes cancer progression by shaping the architecture of the tumour and by suppressing the antitumour activities of immune cells, thus generating an immunosuppressive environment that prevents or attenuates the efficacy of anticancer immunotherapies. The repression of TGFβ signalling is therefore considered a prerequisite and major avenue to enhance the efficacy of current and forthcoming immunotherapie
