Analysis of vaginal cell populations during experimental vaginal candidiasis

P L Fidel Jr et al. Infect Immun. 1999 Jun.

Abstract

Studies with an estrogen-dependent murine model of vaginal candidiasis suggest that local cell-mediated immunity (CMI) is more important than systemic CMI for protection against vaginitis. The present study, however, showed that, compared to uninfected mice, little to no change in the percentage or types of vaginal T cells occurred during a primary vaginal infection or during a secondary vaginal infection where partial protection was observed. Furthermore, depletion of polymorphonuclear leukocytes (PMN) had no effect on infection in the presence or absence of pseudoestrus. These results indicate a lack of demonstrable effects by systemic CMI or PMN against vaginitis and suggest that if local T cells are important, they are functioning without showing significant increases in numbers within the vaginal mucosa during infection.

RT-PCR of T-cell surface marker mRNA expression during primary C. albicans vaginal infection. Total RNA extracted from vaginal tissue or lymph nodes (three mice per group) was subjected to RT-PCR with primers specific for CD3, CD4, CD8, TCR-β constant region, and TCR-δ constant region of systemically derived T cells, using normal or HE Taq DNA polymerase. GAPDH served as the housekeeping gene. (A) RT-PCR of T-cell surface marker mRNA expression in lymph nodes and vaginal tissue of naive mice. (B) Semiquantitative RT-PCR of CD4, TCR-β, TCR-δ, and CD3 during a primary vaginal C. albicans infection. Results over time are expressed as the ratio of each product in pixel intensities to that for GAPDH. Est., estrogen-treated uninfected mice; Est./Inf., estrogen-treated infected mice; Inf., non-estrogen-treated infected mice; beta (b), β-chain; delta (d), δ-chain. The experiment was repeated twice, and the results shown are representative.
