CD79A and infection: IgA is the second most abundant antibody isotype in human serum and its function related to infection and inflammatory homeostasis in mucosal surfaces has been extensively characterized; in innate immune cells, IgA is involved in both pro-inflammatory (the myeloid-cell-specific type I Fc receptor (FcαRI)-dependent responses induced by IgA immune complexes) and anti-inflammatory pathways (FcαRI upon binding of monomeric IgA) [31].
