Objectives To explore the relationship between CD80 expression on lymphocytes at the fetomaternal interface and the fertility characteristics in CBA/J × DBA/2 mice as a model of recurrent spontaneous abortion (RSA) and to investigate the effects of lym phocyte immunotherapy (LIT) on the level of CD80 expression.Materials & Methods The characteristics of fertility in CBA/J × DBA/2 mice were observed in a 120-day period and compared with four normal fertile groups. In anoth er 15 pairs of CBA/J × DBA/2 breedings, resorption rate on day 13 of pregnancy were calculated and the proportion of CD80+ cells at the fetomaternal interface were determined by using two-color flow cytometric analysis, mainly stained with CD80 FITC and CD45-PE. In order to determine the identity of CD80+ cells, the expression levels of CD3(T cell marker), DX 5(NK cell marker), and MHC-Ⅱ(antigen present ing cell marker) were detected in this cell population. Furthermore, the resorption rate and the proportion of CD80+ cells among CBA/J × DBA/2 breedings with and with out immunotherapy were also determined and compared with normal fertile controls.Results The characteristics of abortion in CBA/J × DBA/2 mice were recurrent abor tion on about day 10 of gestation. The resorption rate in CBA/J × DBA/2 mice was significantly higher than that in BALB/c×DBA/2 mice (30. 8% ± 16. 6% vs. 7. 7%± 6. 7%, P< 0. 01). Accordingly, the proportion of CD80+ cells evaluated at the fetomaternal interface in CBA/J × DBA/2 mice was also significantly higher (11. 7%± 5. 8% vs. 3. 9% ± 1. 8%, P< 0. 01). Resorption rate of CBA/J × DBA/2 mice un derwent of LIT was significantly lower than that without LIT, and this decreased rate was correlated with decreased proportion of CD80+ cells.Conclusion In CBA/J × DBA/2 mice model, the characteristics of abortion seem to be peri-implantation embryo-resorption. A correlation between early embryonic waste and higher CD80 proportion at the fetomaternal interface suggests that CD80+ cells may be an important determinant in recurrent peri-implantation abortion.
