title: Immunocytochemical demonstration of DSIP-like immunoreactivity in the hypothalamus of the rat.
abstract: The distribution of delta sleep-inducing peptide immunoreactivity (DSIP-IR) was studied in the rat diencephalon. Varicose nerve fibers exhibiting DSIP-IR were found throughout the mediobasal hypothalamus, most frequently in the hypothalamic arcuate nucleus and in the adjoining median eminence and pituitary stalk. This innervation provides a basis for the involvement of DSIP in neuroendocrine regulation at the hypothalamic level. In the hypothalamus, DSIP-IR innervation was also observed close to the third ventricle and within the mamillary complex. Despite pretreatment with colchicine, no evidence of immunoreactive cell bodies containing DSIP-IR could be found.
