D-Phe-Cys-Tyr-D-Trp-Arg-Thr-Pen-Thr-NH2 (CTAP) is a cyclic, penicillamine-containing octapeptide that is structurally similar to somatostatin and displays greater antagonist potency and selectivity for mu-opioid receptors, compared with the classical mu-selective antagonist D-Phe-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2. The aim of this study was to determine whether CTAP

Previous studies measuring opioid inhibition of cyclic adenosine monophosphate in SH-SY5Y cells supported the hypothesis that continuous agonist stimulation causes a gradual conversion of the mu opioid receptor to a sensitized or constitutively active state termed mu*. Conversion to mu*

Human immunodeficiency virus Gag drives assembly of virions in infected cells and interacts with host factors which facilitate or restrict viral replication. Although several Gag-binding proteins have been characterized, understanding of virus-host interactions remains incomplete. In a series of six

When relatively sated, people (and rodents) are still easily tempted to consume calorie-dense foods, particularly those containing fat and sugar. Consumption of such foods while calorically replete likely contributes to obesity. The nucleus accumbens (NAc) opioid system has long been
