近几年来,关于性腺对垂体促性腺激素的反馈调节作用,人们主要将注意力放在抑制素(inhibin)上。nhibin 是一种糖蛋白,可特异抑制腺垂体释放卵泡刺激素(FSH),而不影响黄体生成素(LH)。1985年,由Mason 等定出猪inhibin A 和inhibin B 的分子结构,它们均含有相同的18 Kα亚单位,经二硫键分别和14Kβ_A 亚单位或β_B 亚单位相连。1986年Vale 和Ling 在从猪卵泡液中分离提纯inhibin 的过程中,分 In recent years, the gonadal feedback regulation of pituitary gonadotropin, the main focus on the inhibin (inhibin). nhibin is a glycoprotein that specifically inhibits the release of follicle stimulating hormone (FSH) from the pituitary gland without affecting luteinizing hormone (LH). In 1985, Mason et al. Determined the molecular structure of porcine inhibin A and inhibin B, both of which contained the same 18 K alpha subunit, and were disulfide bonded to the 14K beta_A subunit or beta_B subunit, respectively. In 1986, Vale and Ling during the isolation and purification of inhibin from porcine follicular fluid, the points
