C3b acceptors on macrophages: inhibition of Fc gamma-receptor-mediated phagocytosis by acceptor-bound C3b.

abstract：BACKGROUND:Interleukin 10 (IL-10) is a cytokine with potent anti-inflammatory properties that play a fundamental role in restrictive host immune response to pathogens, by means of that is a crucial importance for chronic inflammatory disease studies. Therefore, the goal of this study was to measure the correlation of t...
