Papel de las Membranas Asociadas a Retículo Endoplasmático y Mitocondria (MAMs) en la fisiopatología celular de la Ataxia de Friedreich y su relevancia como diana terapéutica

Calcium (Ca2+) is involved in different cellular functions and signaling pathways, mediating between extracellular and intracellular signals. MAMs (Endoplasmic reticulum-mitochondria associated membranes) are specific close appositions formed by the physical interaction of the ER and the mitochondria, thus regulating the main intracellular Ca2+ flux by means of the communication between the two compartments. This is fundamental to maintain cell function and so it has been proposed as a common mechanism in neurodegeneration. Friedreich's Ataxia (FRDA) is an autosomal recessive neurodegenerative disorder in which patients show reduced levels of frataxin (FXN), a protein fundamentally associat…
