We conclude that sauvagine stimulates alpha-MSH secretion through activation of adenylate cyclase and that GABAB receptor activation inhibits secretion through inhibition of cyclic-AMP production
De Koning et al., Endocrinology 1993
:
The tonic inhibition of alpha MSH release in animals adapted to a white background was not affected by 4-aminobutylphosphonic acid, indicating that the GABAB receptor is not ( solely ) involved in the in vivo inhibition of alpha MSH release in animals on a white background
