Abstract
NERVE endings (synaptosomes) isolated from the mammalian hypothalamus contain the hypophysiotrophic hormones which regulate adenohypophysial function. Edwardson et al. have shown1 that release of these neurosecretory substances can be elicited from incubated hypothalamic synaptosomes by electrical or potassium stimulation and the release mechanism has been shown2 to be calcium dependent. We report here that steroid hormones administered both in vivo and in vitro and neurotransmitter substances given in vitro modulate the release of corticotrophin-releasing factor (CRF) from synaptosomes prepared from rat and sheep hypothalamus.
