Abstract:
AIM: To address whether the analysis of CD45~+CD86~+ cells isolated from para-aortic lymph nodes (PLNs) is valuable in assessment of the status of local immunity at the feto-maternal interface. METHODS: CBA/J?DBA/2, virgin CBA/J, and CBA/J?BALB/c mice were used as an abortion-prone model (group A), non-pregnant controls (group N), and fertile controls (group F), respectively. The percentage of CD45~+CD86~+ cell in the CD45~+ cell group (CD45~+CD86~+ percentage for short) and the absolute number of these cells were determined with flow cytometry (FCM), using mononuclear cells isolated from PLNs collected on day 5.5, 9.5, and 13.5 of gestation, respectively, and mononuclear cells from placentas on day 13.5 of gestation. To clarify the identity of these CD86~+ cells, FCM was also performed with CD3, CD19 and DX5 as markers for T cells, B cells, and NK cells, respectively. RESULTS: Both resorption rate and absolute number of resorption were significantly higher in group A (29.3%, 1.8?1.0) than those in group F (4.8%, 0.3?0.5, P
