Mecanismo molecular de resistencia a fármacos en parásitos

Abstract

El mecanismo de resistencia a fármacos es un proceso multifactorial, en el que pueden coexistir varios mecanismos, entre ellos: modificaciones en la entrada del fármaco, inactivación del fármaco, amplificación de genes que codifican para las proteínas blanco de acción o proteínas implicadas en la eliminación del fármaco al exterior celular, mutaciones en la proteína blanco de acción, y reparación del daño celular. En los últimos años, nuestro grupo ha estudiado sobre los protozoos parásitos Leishmania (L. tropica y L. infantum ) y Trypanosoma cruzi, algunos de estos mecanismos, con especial interés en las proteínas transportadoras pertenecientes a la superfamilia ABC (ATP-hinding kasette), conocidas como Glicoproteínas-P, implicadas en la eliminación de fármacos y sustancias tóxicas. El estudio molecular y funcional de estos mecanismos, facilitará el desarrollo de estrategias alternativas de tratamiento a emplear en casos de resistencia a fármacos en parásitos.

Drug resistance is a multifactorial process involving different coexistent mechanisms, among them: modifications of drug entry, intracellular inactivation of drug, amplification of genes coding for target proteins or proteins involved in drug efflux, mutations in target proteins and increased repair of cell damage. Last years, our research group has been involved in the study of drug resistant mechanisms in the protozoan parasites Leishmania (L. tropica y L. infantum) and Trypanosoma cruzi. Our focus has been related with the study of transporters inc1uded in the superfamily ABC (ATP-binding cassette), specifically the P-glycoproteins involved in efflux of drugs and xenobiotics. Molecular and functional studies of these mechanisms, will help significantly the development of treatment alternative strategies to use in case of drug resistance in parasites.
