摘  要:分别用CD3、CD4及CD8分子作为检测T细胞表型亚群的指标,以IFNγ和IL-4作为检测CD4T细胞中Th1与Th2功能亚群的指标,观察了hCG对T细胞各类亚群的作用。结果证明一定剂量范围内的hCG对上述各T细胞功能亚群均有显著抑制作用。用抗hCG各亚单位的单抗封闭hCG后作上述试验,证明抗hCGβ(10号)及抗完整hCG(17号)单抗可阻断上述抑制作用,而抗hCGα单抗(4号)则无此作用,阐明了hCG分子上参与此抑制作用的表位所在。By using the expressing of CD3,CD4 and CD8 molecules as the parameter of T cell phenotypic subpopulation,and the secretion of IFN γ and IL4 as the parameter of Th1 and Th2 functional subpopulation,we studied in vitro the effect of hCG(human Chorionic Gonadotropin) on different subset of T cells.The results showed that hCG can inhibit either phenotypic or functional T cell subset in a ranged dose.These inhibition effects can be blocked after the effective ranged dose of hCG were neutralized by antihCG β and antiintact hCG but not antihCG α monoclonal antibodies.It is suggested that on hCG molecule,the βsubunit or intacthCG are the effective epitopes on inhibition of T cell phenotypic expression or cytokine secreting function.
