Abstract:
We studied the in vitro effects of methionine-enkephalin and D-ala-methionine-enkephalin upon lactating rat mammary gland milk product's secretion and intracellular cyclic AMP levels. Our results show that the lactating gland does not respond to the action of these peptides and suggest that during this period this tissue lacks enkephalin receptors.
