Abstract:
:Fc receptors play important roles for a wide array of immune responses. In contrast to the well-defined Fcγ and Fcε receptors, the molecular and functional characteristics of Fc receptors for IgA and IgM have remained incompletely understood for years. Recent progress has unveiled the characteristics of Fc receptors for IgA and IgM, including Fcα/μ receptor (Fcα/μR) (CD351), polymeric immunoglobulin receptor (poly-IgR), Fcα receptor (FcαRI) (CD89) and Fcμ receptor (FcμR). In this review, we summarize the molecular and functional characteristics of Fcα/μR in comparison with poly-IgR, FcμR and FcαRI, and focus particularly on the pro-inflammatory function of Fcα/μR expressed on marginal zone B cells in sepsis.
