Modelos experimentales de isquemia cerebral

Abstract

Objetivo. Revisar los modelos experimentales de isquemia cerebral utilizados en la investigacion de la fisiopatologia y la terapeutica de esta afeccion. Se expone de forma clara y sencilla tanto el tipo de lesion cerebral isquemica que cada modelo trata de reproducir como los detalles tecnicos especificos para su realizacion practica. Desarrollo. Los modelos experimentales de isquemia cerebral han permitido estudiar la fisiopatologia de esta enfermedad bajo condiciones controladas por el investigador y analizar los efectos de nuevas estrategias terapeuticas. El conocimiento adquirido con estos modelos ha mejorado el pronostico de los pacientes que han sufrido un infarto cerebral isquemico tras la introduccion de agentes tromboliticos y neuroprotectores. Para que un modelo sea valioso debe ser fiable y facil de realizar y debe reflejar lo mas fielmente posible las condiciones clinicas que trata de imitar. Debe ser reproducible y tener una baja variabilidad entre individuos (animales) y entre investigadores. Los roedores pequenos, particularmente las ratas, son los animales con los que se han desarrollado la mayoria de estos modelos por tener una fisiologia y vascularizacion cerebral similares a la humana. Conclusion. Los modelos experimentales suponen actualmente la mejor herramienta para el estudio de los mecanismos subyacentes al dano cerebral isquemico, aunque su simplicidad impide reproducir de forma exacta la lesion cerebral observada en la practica clinica. Esta puede ser la causa de la discrepancia en la respuesta terapeutica observada entre los estudios experimentales y los clinicos
