The BALB/c myeloma protein ABPC48 binds beta(2-6)-linked fructosans and expresses genes derived from the VHX24 and V kappa 10 gene families. We have selected 30 hybridomas expressing the VHX24 gene family derived from mitogen-stimulated spleen cells of naive BALB/c mice and mice injected at birth with the syngeneic monoclonal anti-ABPC48Id, IDA10. The majority of mAb with kappa L chains uses V kappa 1. Antibodies reacting with IDA10 use both V kappa 10 and V kappa 1. Most of these VHX24+ mAb reacted with one or more members of a limited panel of predominantly polysaccharide Ag that have been previously observed to interact with antibodies expressing the VHX24 gene family. Nucleotide sequencing of selected VH and V kappa genes shows a very low frequency of somatic mutation. The effect of neonatal anti-Id injection on VHX24-V kappa pairing and Id expression is discussed.

Systemic and mucosal humoral immune responses have been reported to exhibit an age related decline. However, differences in primary and memory responses at mucosal sites in aged mice have been noted. In an effort to begin characterizing deficiencies in the mucosal system of aged mice, we examined the B cell compartment of gut associated Peyer's patch lymphoid tissue.

In this study we compare VH-gene repertoires of short-lived and persistent B lymphocytes in normal nonimmunized mice. Enriched populations of persistent peripheral B cells were obtained in vivo either by (i) repeated injections with hydroxyurea or (ii) maintained ganciclovir administration to herpes simplex virus-1 thymidine kinase transgenic mice. Both approaches have previously been shown to deplete newly formed, short-lived B cells.

A collection of hybridomas from C57BL/6 mice producing antibodies to dextran B512 was analysed and found to reflect the immune response in vivo with regard to immunoglobulin class expression, T cell dependency and antibody affinity. IgM-, IgG-3, and IgG-2b, and IgA-producing hybridomas were found. IgG3-producing hybridomas were obtained from nude mice, indicating T cell independent IgG3 synthesis.
