Fenotipo celular de las neuronas sensitivas afectadas en la ataxia de Friedreich

Abstract

La FRDA es una enfermedad caracterizada por la afectación primaria del ganglio dorsal. La falta de frataxina no afecta por igual a todos los tipos neuronales del ganglio dorsal, siendo las neuronas propioceptivas las más dañadas. Esto nos lleva a cuestionarnos porque este tipo neuronal es más sensible a una deficiencia de frataxina. Esta tesis doctoral se ha centrado en la investigación de la biología celular de frataxina en neuronas sensitivas del ganglio dorsal y las consecuencias fisiopatológicas del déficit de frataxina en el modelo murino YG8R. La caracterización molecular y bioquímica de las neuronas sensitivas, especialmente de las propioceptivas, en condiciones fisiológicas y de déficit de frataxina, ha permitido identificar nuevos marcadores selectivos de esta población neuronal e identificar aquellos mecanismos fisiopatológicos que provocan la neurodegeneración primaria del ganglio dorsal en la FRDA. Además, es interesante comprobar cómo estos procesos afectan a la neurona, distinguiendo dos localizaciones: el soma y el axón. La respuesta a estas cuestiones nos ha ayudado a comprender el papel de la frataxina en los mecanismos moleculares relacionados con los procesos de neurodegeneración y ha abierto nuevas vías celulares de estudio y la implementación de nuevos tratamientos farmacológicos en la FRDA.
