The levels of TNF-α, IL-2 and IFN-γ in the serum were determined by meansof radioimmunoassay (RIA).Results:The level of serum AzpAb in the POF patients was significantly higher thanthat of the normal controls(P<0.001). The levels of TNF-α and IL-2 were significantlyreduced (P<0. 001), and the level of IFN-γ was significantly elevated (P<0.01). Thelevels of above three cytokines in AzpAb positive group were significantly higher thanthose of the negative group in POF patients.Conclusion: This study suggested that AzpAb, TNF-α, IFN-γ and IL-2 might playimportant roles in the pathogenesis of autoimmune POF.展开更多

An ABC immunohistochemistry was used to evaluate reaction of mAb 17D3pZP to porcine and human ZP antigens as well as important human tissue antigens. Results mAb 17D3pZP specifically bound to porcine and human ZP antigen, but not to other cells of ovaries and other important human tissue antigens. Conclusion 17D3 anti-pZP mAb can recognize porcine and human ZP antigen without cross-reaction with other human tissue antigens including ovary, so it may further help us to abstract and purify corresponding target antigen and settle basis for producing human ZP contraceptive vaccine.展开更多
