Conference

Internacional Gap Junction

Conferencia científica internacional que cubre todos los aspectos relacionados con la comunicación celular medida por conexinas, ponexinas e inexinas. El programa de estas conferencias cubre un amplio rango de temas de vanguardia que van desde la bioquímica estructural a la biología celular, la fisiología molecular hasta ensayos clínicos. La mayoría de los asistentes son científicos extranjeros provenientes de cinco continentes.

Comité Organizador invita a científicos, postdoctorales y estudiantes de todo el mundo para asistir y participar activamente en la Conferencia 2015 Internacional Gap Junction en Valparaíso, Chile. Esta conferencia es una excelente oportunidad para interactuar y discutir varios aspectos del campo con científicos de todo el mundo.

Esta conferencia internacional es organizada por el Centro Interdisciplinario de Neurociencia de la Universidad de Valparaíso.
