Gonadotropin-releasing hormone(GnRH) is a crucial peptide for the regulation of reproduction.Using immunological techniques,we investigated the presence of GnRH in horseshoe crab Tachypleus tridentatus.Octopus GnRH-like immunoreactivity,tunicate GnRH-like immunoreactivity,and lamprey GnRH-like immunoreactivity were detected in the neurons and fibers of the protocerebrum.However,no mammal GnRH-like immunoreactivity or lamprey GnRH-Ш-like immunoreactivity was observed.Our results suggest that a GnRH-like factor,an ancient peptide,existed in the brain of T.tridentatus and may be involved in the reproductive endocrine system.  相似文献
