Trace Amine Associated Receptor 1 Modulates Behavioral Effects of Ethanol

http://www.la-press.com/redirect_file.php?fileId=5004&filename=3707-SART-Trace-Amine-Associated-Receptor-1-Modulates-Behavioral-Effects-of-Etha.pdf&fileType=pdf

Background: Few treatment options for alcohol use disorders (AUDs) exist and more are critically needed. Here, we assessed whether trace amine associated receptor 1 (TAAR1), a modulator of brain monoamine systems, is involved in the behavioral and reinforcement-related effects of ethanol and whether it could potentially serve as a therapeutic target.

Methods: Wild-type (WT) and TAAR1 knockout (KO) mice (75% C57J/BL6 and 25% 129S1/Sv background) were compared in tests of ethanol consumption (two-bottle choice [TBC]), motor impairment (loss of righting reflex, [LORR], locomotor activity) and ethanol clearance (blood ethanol level [BEL]).

Results: As compared with WT mice, KO mice displayed (1) significantly greater preference for and consumption of ethanol in a TBC paradigm (3%–11% vol/vol escalating over 10 weeks), with no significant difference observed in TBC with sucrose (1%–3%); (2) significantly greater sedative-like effects of acute ethanol (2.0 or 2.5 g/kg, intraperitoneal [i.p.]) manifested as LORR observed at a lower dose and for longer time, with similar BELs and rates of ethanol clearance; and (3) lower cumulative locomotor activity over 60 minutes in response to an acute ethanol challenge (1.0–2.5 g/kg, i.p.).

Conclusions: The present findings are the first to implicate TAAR1 in the behavioral and reinforcement-related effects of ethanol and raise the question of whether specific drugs that target TAAR1 could potentially reduce alcohol consumption in humans with AUDs.

DATIS is an evolving system and an integral component of Ontario’s performance measurement system. Linkages with healthcare information systems will allow for longitudinal tracking of client health-related outcomes.

Rasgos patológicos de personalidad y metabolitos cerebrales como predictores de

no abstinencia en adictos con trastornos de personalidad

http://www.adicciones.es/files/208-219%20Serrani.pdf

Resumen:

Se investigaron diferencias en rasgos de personalidad patológicos y alteraciones en metabolitos cerebrales entre no consumidores, consumidores abstinentes y no abstinentes. Los participantes (n=113) entre 18–45 años con trastorno de personalidad (TP) fueron diagnosticados con entrevistas clínicas y escalas para depresión, ansiedad, impulsividad y dimensiones de patologías de personalidad. Los metabolitos cerebrales se analizaron con resonancia magnética con espectroscopía. Los datos se analizaron con ANOVA y comparaciones múltiples. Abstinentes y no abstinentes se distinguieron de no consumidores por desregulación emocional, inhibición, y expresión restringida; abstinentes y no abstinentes se distinguieron entre sí en auto-agresión, comportamiento disocial, problemas de conducta, búsqueda de estímulos y problemas de intimidad. Niveles de N-Acetil Aspartato

y Creatina fueron menores para no abstinentes en cortezas prefrontal, cingulada anterior, vermis cerebeloso y corona radiada superior. Para abstinentes, niveles de colina fueron mayores en vermis cerebeloso y niveles de n-acetil aspartato fueron menores en corteza prefrontal dorsolateral, cingulada anterior e ínsula. En cuanto a rasgos de personalidad, apego inseguro, narcisismo, labilidad, autoagresión y ansiedad caracterizan a consumidores y abstinentes; en tanto suspicacia, rechazo y dureza de carácter se encuentran en consumidores (no abstinentes y abstinentes). Rasgos compulsivos, impulsión corporal no planeada, y descontrol en regulación de emociones predominaron en no abstinentes y participantes con co-morbilidades. Desapego e inhibición predominan en Trastorno por uso de Alcohol y rasgos narcisistas en uso de Sustancias.
