Abstract

Immunization with Neisseria meningitidis group B capsular polysaccharide (CpsB) elicited responses in adult mice that showed the typical dynamic characteristics of the response to a thymus-independent antigen, in contrast to the thymus-dependent behavior of antibody responses to CpsC. The former had a short latent period and showed a rapid increase in serum antibodies that peaked at day 5, and immunoglobulin M (IgM) was the major isotype even though IgG (mainly IgG2a and IgG2b) was also detectable. This response was of short duration, and the specific antibodies were rapidly cleared from the circulation. The secondary responses were similar in magnitude, kinetics, IgM predominance, and IgG distribution. Nevertheless, a threefold IgG increase, a correlation between IgM and IgG levels, and dose-dependent secondary responses were observed. Hyperimmunization considerably reinforced these responses: 10-fold for IgM and 300-fold for IgG. This favored isotype switch was accompanied by a progressive change in the subclass distribution to IgG3 (62%) and IgG1 (28%), along with the possible generation of B-cell memory. The results indicate that CpsB is being strictly thymus independent and suggest that unresponsiveness to purified CpsB is due to tolerance.
