Abstract excerpt
X-linked immunodeficient (Xid) mice carry a Bruton's tyrosine kinase (Btk) mutation and exhibit a selective failure to produce antibodies against bacterial capsular polysaccharides. Studies in vitro point to a fundamental survival defect of Xid B cells after receptor cross-linking by thymus-independent type-2 (TI-2) antigen because B cells undergo apoptosis without proliferating. We describe results from a novel...
