FcγRIIB Deficiency Leads to Autoimmunity and a Defective Response to Apoptosis in Mrl-MpJ Mice

Abstract excerpt

Data suggests that modulation of FcgammaRIIB expression represents a significant risk factor for the development of autoimmunity. In this study, we investigated this notion in mice that possess genetics permissible for the development of autoimmunity. To this end, Mrl-MpJ Fcgr2b-/- mice were monitored for the development of autoreactivity. We found that FcgammaRIIB deficiency led to chronic B cell activation...
