X. Casabiell et al., PRESENCE OF LEPTIN IN COLOSTRUM AND OR BREAST-MILK FROM LACTATING MOTHERS - A POTENTIAL ROLE IN THE REGULATION OF NEONATAL FOOD-INTAKE/, The Journal of clinical endocrinology and metabolism, 82(12), 1997, pp. 4270-4273
In neonates both nutrients and regulatory factors are transferred from
the mother to the suckling infant via milk. In the present work, it h
as been shown that human milk contains immunoreactive leptin which is
identical to intact human leptin by criteria of charge, size, immunore
cognition and SDS-PAGE mobility. In experimental animals it was demons
trated that leptin is transferred from the circulation to mothers' mil
k, then to the infant's stomach and afterwards to infant blood. Matern
al leptin in milk may play a regulatory role in the suckling infant.
