RESUMEN
Este trabajo se centra en los efectos de los endocanabinoides en procesos inflamatorios. Presenta un panorama general de los canabinoides, su estructura, efectos y principales mecanismos de acción. Se revisan también las generalidades de los procesos inflamatorios y algunos de los principales mediadores involucrados, así como el papel modulador de los endocanabinoides en los procesos de inflamación y algunas posibilidades de intervención terapéutica. Los canabinoides actúan preferentemente sobre receptores específicos acoplados a proteínas G
i. Los endocanabinoides mejor caracterizados son la araquidonil etanolamida (AEA o anandamida) y el 2-araquidonil glicerol (2-AG). Estos compuestos se sintetizan en respuesta a elevaciones intracelulares de calcio y difunden de las neuronas postsinápticas a las presinápticas actuando como mensajeros retrógrados. Recientemente, los endocanabinoides han sido identificados como compuestos con potente actividad antiinflamatoria, capaces de inhibir distintas etapas de los procesos de control de las infecciones y el daño tisular. Todas estas características han abierto un panorama donde el uso adecuado de este tipo de compuestos podría mejorar la terapia para múltiples enfermedades crónico-degenerativas.
