The human Fc receptor for IgA (Fc alpha RI, CD89
) on transgenic peritoneal macrophages triggers - phagocytosis and tumor cell lysis.
The flow cytometric analysis of their phenotypic markers showed that BM-MSCs of AA patients as well as of controls expressed comparable levels of MSC markers CD73, CD89
, CD105, and CD166 and lacked the expression of CD13, CD34, CD45, and HLA-DR (Figure 1(a)).

) is a receptor for IgA and plays important roles in immune responses, and it is expressed constitutively on monocytes, macrophages, eosinophils, neutrophils, and some types of dendritic cells.
Hypogalactosylated IgA molecules evoke the synthesis of IgG autoantibodies that form circulating immune complexes that end up entrapped in the mesangial area due to interactions between CD89
and mesangial cell receptors like CD71.

Based upon their functional involvement, several genes like core-1-b, 3-galactosyltransferase (C1GALT1) and its specific molecular chaperone b1, 3-GT (C1GALT1C1) GalNAc a2, 6-sialyltransferase (ST6GALNAC2) transferrin receptor (TFRC) immunoglobulin A, Fca receptor (CD89
) and toll like receptor 4 (TLR4) become promising candidate genes for IgAN.
They found that insulin increased the total number of neutrophils and the number of these expressing CD11b, CD15, CD62L, and CD89
, whereas the density of these molecules was downregulated.
