Abstract excerpt
X-linked lymphoproliferative disease is caused by mutations affecting SH2D1A/SAP, an adaptor that recruits Fyn to signal lymphocyte activation molecule (SLAM)-related receptors. After infection, SLAM-associated protein (SAP)-/- mice show increased T cell activation and impaired humoral responses. Although SAP-/- mice can respond to T-independent immunization, we find impaired primary and secondary T-dependent...
