摘要:
A rabbit antibody against an N-terminal portion of rat prostaglandin EP3 receptor (EP3R) was produced to examine the distribution of EP3R in the rat hypothalamus. The antibody specifically recognized EP3R proteins in rat brain extract, in membrane fractions of rat kidney, and in membrane fractions of EP3R-expressing culture cells. Intense EP3R-like immunoreactivity was observed in the median preoptic nucleus, medial preoptic area, parastrial nucleus, compact part of the dorsomedial hypothalamic nucleus, and dorsal part of the premammillary nucleus. These results suggest that prostaglandin Ep mediates various actions in the hypothalamus, such as fever induction in the preoptic area, through EP3R. (C) 1999 Elsevier Science ireland Ltd.
