Abstract
Mice mount a normal primary antibody response on stimulation with the thymic-independent antigen trinitrophenylated lipopolysaccharide (TNP-LPS). Although we have previously reported the generation of functional B-memory lymphocytes to TNP-LPS, this memory response was only observed in few mouse strains. Here we have used congeneic mouse strains in an attempt to locate the genetic regions involved in the memory response. We show that genes of the major histocompatibility complex (MHC) do not have a critical role but that genes coding for the variable region of immunoglobulin heavy chains or gene(s) closely linked to them are required for memory cell induction by TNP-LPS.
