Acetaldehyde as a drug of abuse: insight into AM281 administration on operant-conflict paradigm in rats

2013

Increasing evidence focuses on acetaldehyde (ACD) as the mediator of the rewarding and motivational properties of ethanol. Indeed, ACD stimulates dopamine release in the nucleus accumbens and it is self-administered under different conditions. Besides the dopaminergic transmission, the endocannabinoid system has been reported to play an important role in ethanol central effects, modulating primary alcohol rewarding effect, drug-seeking and relapse behaviour. Drug motivational properties are highlighted in operant paradigms which include response-contingent punishment, a behavioural equivalent of compulsive drug use despite adverse consequences. The aim of this study was thus to characterize…

EFFECT OF ACETALDEHYDE INTOXICATION AND WITHDRAWAL ON NEUROPEPTIDE Y EXPRESSION. FOCUS ON CB1 RECEPTOR ROLE.

2014

Neuropeptide Y (NPY) acts as an endogenous anxiolytic, and, like endocannabinoids, plays an important role in the regulation of neuronal excitability during ethanol withdrawal (Rubio et al., 2011). Since acetaldehyde is considered a mediator of ethanol central effects, this research aims at investigating, following intoxication and during withdrawal, the effects of acetaldehyde on NPY expression in brain areas particularly vulnerable to alcohol, and the influence of cannabinoid system on it. Rats underwent acetaldehyde intoxication (450mg/kg, i.g., 4 times daily for 4 days); AM281, a CB1 selective antagonist (2,5 mg/kg, i.p.) was administered during abstinence. Immunohistochemical analysis …
