Induction of antigen-specific antibody response in human pheripheral blood lymphocytes in vitro by a dog kidney cell vaccine against rabies virus (DKCV).

In the present report an in vitro method for obtaining a secondary human antibody response to a dog kidney cell vaccine against rabies virus (DKCV) is described. Cultures of peripheral blood mononuclear cells from normal rabies-immune and nonimmune donors were stimulated in vitro by DKCV. The production of virus-specific antibody in supernatant fluids was monitored by ELISA. Antibody was produced by lymphocytes from rabies-immune individuals, whereas those of nonimmune subjects consistently failed to produce anti-rabies antibodies after in vitro stimulation with DKCV. The generation of the anti-rabies virus antibody response of lymphocytes stimulated with DKCV was shown to be an antigen-dependent, as well as an antigen-specific process. Optimal antigen-specific response

Absence of a correlation between humoral and cellular responses to vaccinia virus and products of the major histocompatibility complex in rhesus monkeys

62 Rhesus monkeys were tested at different times after vaccinia virus infection for virus-specific induction of lymphocyte proliferation in vitro or antibody production in vivo. No association was found between identifiable RhLA-controlled antigens and the strength of the cellular proliferative and/or humoral response.
