| Research Abstract |
We evaluated the expression of SIRPα on B cell in cytidine monophospho-N-acetylneuraminic acid hydroxylase-deficient mice. There are no SIRPα expressed B cells in the spleen, bone marrow and peripheral blood. However, B cells in the peritoneal cavity only expressed high levels of SIRPα. About 80% of B cells in the peritoneal cavity were B-1 cells. Furthermore, B-1a and B-1b cells expressed high levels of SIRPα. In contrast, B-2 cells did not express the SIRPα.
