The effect of c-Fos expression in tuberomammillary after exciting ventrolateral preoptic and its receptor passway
摘要
Abstract
Objective To investigate the effect of c-Fos expression in tuberomammillary nucleus ( TMN) after ex-citing ventrolateral preoptic ( VLPO) and its receptor passway. Methods The expressions of mGluR5 in VLPO and GABAA Rβ1 in TMN were determined by immunostaining. L-Glutamate ( L-Glu) was microinjected into VLPO with stereotaxic technique to observe the changes of c-Fos expression in TMN. Results Positive protein of mGluR5 could be identified by Anti-mGluR5 in VLPO and also positive protein of GABAAR was identified in TMN by Anti-GABAARβ1. c-Fos expression in TMN reduced after microinjecting L-Glu in VLPO compared with the control group. The difference between them was significant (P<0. 01). Conclusion The metabotropic glutamate recep-tor in VLPO and GABA receptor in TMN mediate the regulation of VLPO-TMN passway. VLPO inhibits the TMN neuronal activity via GABAAR.关键词
