| Popis: | To date, it has not been possible to study antigen-specific T cell responses during primary infection of the genital tract. The low frequency of pathogen-specific T cells in a naïve mouse makes it difficult to monitor the initial events after antigen encounter. We developed a system to examine the response of pathogen-specific T cells in the genital mucosa after intrauterine infection. We identified the protective CD4+T cell antigen Cta1 fromChlamydia trachomatisand generated T cell receptor (TCR) transgenic (tg) mice with specificity for this protein. By transferring TCR tg T cells into naïve animals, we determined thatChlamydia-specific T cells were activated and proliferated in the lymph nodes draining the genital tract after primary intrauterine infection. Activated T cells migrated into the genital mucosa and secreted IFN-γ. The development ofChlamydia-specific TCR tg mice provides an approach for dissecting how pathogen-specific T cells function in the genital tract. |
