Sažetak
Introduction: Ectopic pregnancy represents a model for investigation of immunoregulation at the maternal-fetal interface.The aim was to examine the presence and distribution of leukocyte subpopulations, perforin (P) and IL-15 expression and cytokine profiles in fallopian tuba ectopic pregnancy. Material and Methods: Samples from (a) tubal mucosa at the implantation site, (b) tubal mucosa away from the implantation site, and (c) intrauterine (i.u.) decidua were analyzed. Lymphocyte subpopulations, perforin and IL-15 cytokine expression were determined by immunohistology and flowcytometry. Results: CD3+ and CD8+ cells predominate (60%) over CD56+ cells at tubal implantation site (15%) while intrauterine decidua contained less than 10% of CD3+ cells and around 70% of NK cells which is approximately equal to decidua of normal pregnancy. Many P+ and IL-15+ cells were present in i.u. decidua but rare in tubal mucosa. 50% of lymphocytes from i.u. decidua are P+ but only 5% at tubal implantation site. In i.u. decidua P was mostly distributed in CD56+ NK cells (90%) while in both sites of tubal mucosa was equally distributed between CD56+ and CD3+ cells. Conclusions: The number of NK cels, P+ and IL-15+ cells at tubal implantation site is significantly lower compared to i.u. implantation site in normal pregnancy, what could be responsible for insufficient control of trophoblast growth in ectopic pregnancy.
