Objective:To investigate the effects of anti-CTLA4 antibody on Th1/Th2 shift in unexplained recurrent spontaneous abortion. Methods:The levels of IL-2
IFN-γand IL-4 were assessed by ELISA in the supernatant of cultured maternal peripheral blood mnnonuclear cells(PBMC) from 30 patients of Unexplained RSA. Cytokine synthesis was induced by activation with antigens from a chnriocarcinoma cell line of JEG-3
with anti-CTLA4 antibodv or IgG. Results:We detected significantly greater levels of the Th1 cytokines IL-2、IFN-γ(P<0.05)and lower levels of the Th2 cytnkines IL-4(P<0.01)in anti-CTLA4 antibody groups
compared with control group of the same concentration. Between the trial groups of different concentration
there is no significance(P>0.05). Conclusion:Anti-CTLA4 antibody can up-regulate Th1-type cytokines and down-regulate Th2-type cytokines
which indicates that in URSA anti-CTLA4 antibody could swith T cell responses to Thl
