Development of murine B cell subpopulations
1I.C.R., Fox Chase Cancer Center, Philadelphia, PA 19111.
The generation of diverse B cell subpopulations in the mouse is the subject of considerable current interest. In this review, I first describe a general framework for antigen-independent B cell differentiation in the adult bone marrow including results from in vitro culture systems. In following sections, effects on B cell development in several immunodeficient strains and transgenic lines are presented. Next, the CD5+ B cell subpopulation is covered in some depth, including data on development, physiology and repertoire selection. Finally, another selected population, memory B cells, together with their likely origins in the germinal center are discussed.

B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
