title: Characterization of immune responses following intramuscular DNA immunization with the MOMP gene of Chlamydia trachomatis mouse pneumonitis strain.
abstract: Studies were carried out to characterize the cellular and humoral immune responses evoked by intramuscular DNA vaccination with the major outer membrane protein (MOMP) gene of Chlamydia trachomatis mouse pneumonitis strain. The data demonstrate that DNA vaccinated mice develop antigen-specific delayed-type hypersensitivity, lymphocyte proliferation and interferon-gamma (IFN-gamma) production. Serum antibody responses (mainly immunoglobulin G2a; IgG2a) were evoked in two-thirds of the mice. We conclude that intramuscular DNA immunization with the MOMP gene evokes cellular and humoral immune responses suggestive of a T helper 1 (Th1) bias.
