Effect of supernatants from cord blood mononuclear cells and peripheral blood mononuclear cells on infection of HIV-1 in vitro / 中国病理生理杂志

ABSTRACT

AIM: To study the effect of supernatants from cord blood mononuclear cells (CBMC) and peripheral blood mononuclear cells (PBMC) on infection of HIV-1 in vitro, and develop effectively soluble factors for human acquired immunodeficiency syndrome (AIDS) treatment. METHODS: Different supernatants from CBMC and PBMC activated by PHA for 5 hours and 12 hours were added to cell culture systems between HIV-1ⅢB/H9 cells labeled by calcein-AM and MT-2 cells, then to count the fusion under a reverted fluorescent microscope after 2 hours, respectively, and different soluble factors in supernatants were detected by Luminex 100~ TM . RESULTS: These supernatants from CBMC and PBMC activated by PHA for 5 hours and 12 hours inhibited the formation of fusion, and there is no difference between supernatants collected in CBMC and PBMC at same time point. However, the supernatants collected in 5 hours were more effective to inhibit the formation of fusion than those in 12 hours (P
