Integrin alpha v beta 3 is an adhesion molecule thought to be relevant to blastocyst attachment. It is expressed by endometrial epithelial cells at the time of ''implantation window,'' and its expression may be altered in women with implantation failure. Integrin alpha v beta 3 is also expressed by T lymphocytes. Because immune cells interact with endometrial tissues via integrins, we hypothesized that expression of integrin alpha v beta 3 in endometrium and in peripheral blood lymphocytes may correlate. A total of 41 women with implantation failure underwent endometrial biopsy and blood collection at the time of implantation window. Integrin alpha v beta 3 expression was evaluated in fresh frozen endometrial specimens using immunohistochemistry and on T lymphocytes using flow cytometry. Statistically significant negative correlation was found between integrin alpha v beta 3 in endometrium and T lymphocytes. Integrin alpha v beta 3 expression on T lymphocytes does not predict its endometrial expression.
