Strain-dependent migration of lymphocytes to the vaginal mucosa after peripheral immunization.
We have previously demonstrated a genetic predisposition among mice regarding their ability to be protected against vaginal candidiasis after peripheral immunization. Both BALB/c and (BALB/cx C57BL/6) F1 mice are protected against vaginal candidiasis after subcutaneous immunization with Candida albicans extract and C57BL/6 mice are not protected by this immunization. In the present study, the ability of F1-derived immune cells to transfer protection to naive parental strains was observed in BALB/c recipient mice, but not apparent in B6 recipient mice. This result is highly suggestive that the microenvironment of the B6 mouse is responsible for the susceptible phenotype. Genetic studies using (BALB/cx C57BL/6)F1x C57BL/6 backcross mice demonstrated that two genes appeared to regulate the protective effect of peripheral immunization to vaginal challenge. Microsatellite mapping indicated that candidate loci involved in controlling the immune response to vaginal candidiasis after peripheral immunization included the intercellular adhesion molecule-1 (ICAM-1), the Icam-1 related sequence 1, and the Fc epsilon RII (P<0.01). Thus, the ability of cells to bind to vaginal endothelial cells may play an important role in protection against vaginal candidiasis mediated by peripheral immunization.[1]References
