Psicobiología del alcohol: Función del calcio intracelular en la activación de la proteina Kinasa A y sus consecuencias conductuales de su manipulación

Abstract

Treball Final de Grau en Psicologia. Codi: PS1048. Cursacadèmic 2013-2014 Currently, alcohol is one of the most consumed drugs worldwide. However, despite all the advances in neuroscience, mechanism of action of alcohol at a central level is still unknown. The main objective of this work is proposing and testing a hypothesis about how alcohol works in the brain, based on the idea of its operation on intracellular calcium and different mediators of cAMP-PKA cascade. The method of this paper consists of the analysis of 4 studies that show the manipulations of the different mediators of calcium and cAMP-PKA and the consequences of these manipulations at a molecular, cellular, neurobiological and behavioural level. The results show that, possibly, these mediators of calcium are very important in explaining the mechanism of action of alcohol on the brain. However, it cannot be assumed the exact mechanism by which alcohol acts at a central level. Actualmente, el alcohol es una de las drogas más consumidas a nivel mundial. Sin embargo, a pesar de todos los avances de la neurociencia, el mecanismo de acción del alcohol a nivel central aún es desconocido. El objetivo principal de este trabajo es tratar de plantear y probar una hipótesis de cómo funciona el alcohol en el cerebro, partiendo de la idea de su funcionamiento sobre el calcio intracelular y diferentes mediadores de la cascada AMPc-PKA. El método de este trabajo consta del análisis de 4 estudios que muestran las manipulaciones de diferentes mediadores de calcio y AMPc-PKA y las consecuencias de esas manipulaciones a nivel molecular, celular, neurobiológico y conductual. Los resultados nos muestran que, posiblemente, estos mediadores de calcio sean muy importantes a la hora de explicar el mecanismo de acción del alcohol en el cerebro. Sin embargo, aún no se puede afirmar con certeza claridad el mecanismo exacto por el que el alcohol actúa a nivel central.
