美国迭戈圣加利福尼亚大学的研究人员在某些妇女中鉴定了一种自然产生的“抗激素”,可能导致新避孕药的产生。此种抗激素几乎与卵泡刺激素(FSH)完全相同,它与FSH受体结合,在免疫测定时与FSH交叉反应,但没有生物活性。研究人员推测此种抗激素携带的碳水化物部分与正常FSH的差别很小;通过与生物活性FSH竞争受体位点,此抗激素有效地抑制FSH活性。研究组发现,此种抗激素是生 Researchers at the University of San Diego, in the United States, have identified a naturally occurring “anti-hormone” in some women that could lead to the production of new birth control pills. This anti-hormone is almost identical to follicle stimulating hormone (FSH), binds to the FSH receptor and cross-reacts with FSH on an immunoassay but is not bioactive. The researchers hypothesized that the part of the carbohydrate carried by this anti-hormone had little difference from normal FSH; this anti-hormone effectively inhibits FSH activity by competing with bioactive FSH for receptor sites. The research team found that such anti-hormones are raw
