Abstract：
:Age-related differences in opiate receptors were determined using young (1 month old), mature (3 and 8 months old) and aged (20 months old) mice. 3H-Dihydromorphine binding to mu-receptors in brain synaptic membranes consisted of two components: one with high affinity and one with low affinity. High affinity mu binding sites in membranes from young and aged mice had significantly less receptor densities and higher affinities than the mature mice. In the membranes from aged mouse brain, the affinity of low affinity binding sites for 3H-dihydromorphine was also significantly increased when compared to those in membranes from the 8-month-old group. Membranes from the young and aged groups revealed significantly higher affinity for binding of the kappa ligand, 3H-(-)ethylketocylazocine, than mature mice, which was not accompanied by any change in the density of the receptors. There was no change in either the number or affinity of the binding sites for 3H-(D-Ser2-Leu5)-enkephalinyl-Thr, the delta receptor ligand, among young mature and aged groups.
