弓形虫速殖子感染对HeLa细胞凋亡的影响
Effect of Toxoplasma gondii tachyzoite infection on HeLa cell apoptosis
摘要
Abstract
Objective:To explore HeLa cell apoptosis when infected with different number of T.gondii tachyzoites.Methods:HeLa cells were cultured in 24-wells plates for 16 h and incubated with different number of T.gondii tachyzoites.Mter infected for 4 h,the concentration of 0.5 μg/mL actinomycin D was added into the medium.The cells were collected in 8,12,24 and 36 h.The apoptosis of HeLa cell was determined by Hoechst 33258 stain and Annexin V-FITC/PI method.Results:When the rate of parasites/ cells (multiplicity of infection,MOI) was no more than 1 (MOI ≤ 1),the parasites could suppress the cell apoptosis.When MOI > 1 and the infection time over 24 h,the parasites could accelerate the cells apoptosis.Conclusion:T.gondii tachyzoite infection could affect the HeLa cell appotosis in vitro,and the incidence was related to the number of tachyzoites.关键词
