INTRODUCTION: Rat Wistar has been used as a
model to study endometriosis. It has not been well described the alterations on immune
system associated to the endometriosis. In our experience, treatment with recombinant IL-2
has a clinical benefit on women with endometriosis. The aim of this study is know the
effect of IL-2r on implantation and development of ectopic endometrium. MATERIAL AND METHODS: Fifty Wistar rats were divided
into four groups: a) no endometriosis; b) no endometriosis treated with intraperitoneal
IL-2r; c) induced endometriosis; d) induced endometriosis treated with IL-2r. After 30
days, the rats were put on sleep and endometriotic vesicles were obtained. The tissue
samples were sectioned and analysed by immunohistochemical staining with monoclonal
antibodies.
RESULTS: We have observed an expression of
CD25+, CD29+, CD80+, activated macrophages and dendritic cells on endometriotic vesicles
from rats treated with IL-2r.
CONCLUSION: Treatment with IL-2r on
experimental endometriosis induces the presence of activated cells in local lesion. That
could explain an elevated production of proinflammatory cytokines observed in women with
endometriosis.
