immune system
• bone marrow chimeric mice have reduced ability to generate memory B cells in response to low-dose antigen
• B cells fail to internalize complement coated immune complexes
• bone marrow chimeric mice containing mutant B cells fail to produce antigen-specific antibodies
• bone marrow chimeric mice have reduced ability in class switch recombination in response to low dose antigen
• B cells fail to react to sub-optimal doses of antigen coated in C3 complement
