1 These data suggest: (1) ovarian steroid treatment recruits quiescent lactotropes to release PRL; (2) E2 treatment alone or in combination with P4 increases the amount of PRL rleased by individual lactotropes; (3) E2-induced alterations in the frequency distribution and lactotrope responsiveness to DA may be due in part to a decreased expression of Gialpha3/Galphao.
