Campideli-Santana AC, da Costa Silva KS, Araújo-Lopes R, Antunes LM, Szawka RE (2023) Submaximal loss of KNDy neurons accelerates and amplifies pulsatile LH secretion in female rats. J Endocrine Society 7(S1):bvad114.1214. doi: 10.1210/jendso/bvad114.1214
Objective: To investigate the impact of the submaximal loss of KNDy neurons on the pulsatile secretion of luteinizing hormone (LH) in female rats.
Summary: The study found that a partial loss of these neurons led to irregular estrous cycles and increased frequency and amplitude of LH pulses. This suggests a new role for KNDy neurons in moderating LH pulse frequency and amplitude in ovary-intact animals, with implications for early antral follicle recruitment.
Usage: Adult female rats underwent a neurochemical ablation of KNDy neurons via intra-ARC stereotaxic injections of NKB-SAP (IT-63), while control animals received Blank-SAP (IT-21).
