Interleukin-1 directly stimulates the release of corticotrophin releasing factor from rat hypothalamus.

abstract：:An enriched population of cells immunoreactive to antiserum against S-100 protein, a marker of folliculo-stellate (FS) cells in the rat pituitary, was obtained by separation of dispersed pituitary cells from adult female rats by gradient sedimentation at unit gravity.
