title: Lessons from human genetic variants in the study of B-cell differentiation.
abstract: Several human B-cell immunodeficiencies result from mutations in signal transducing molecules. The past year has seen significant advances in our understanding of how these molecules are integrated into B cell signaling pathways. The phenotypes of mice deficient in several of these genes have revealed species-specific differences in the requirements for early B cell development.
