Biphasic clearance of incompatible red blood cells through a novel mechanism requiring neither complement nor Fcγ receptors in a murine model

Abstract

These data demonstrate a biphasic HTR, the first phase involving sequestration of incompatible hGPA RBCs and the second phase involving phagocytosis of sequestered RBCs. However, the mechanism(s) of phagocytosis in the second phase required neither C3 nor FcγRs. These findings demonstrate novel mechanistic biology of HTRs.
