Regulation of immune responses via genetically restricted cellular interactions. II. I-region-restricted cooperation between idiotypic and anti-idiotypic B lymphocytes.


Immunization of BALB/c mice with MOPC-104E myeloma protein induced idiotype-specific enhancing cells which acted on anti-dextran antibody-producing cells. The enhancing cells have surface phenotypes of B cells. Using BALB/c H-2 congenic strains, it was found that the cooperation between anti-idiotypic-enhancing B lymphocytes and dextran-primed B lymphocytes… (More)
