"Patients with long COVID and ME/CFS displayed higher proportions of type IIa/IIx fibers, and signs of intrinsic mitochondrial dysfunction, observations that were not seen following bed rest." "As mitochondrial and endothelial dysfunction appear prominent in both long COVID and ME/CFS, with clear implications on oxygen extraction, future studies should aim to investigate the viability of improving patient mitochondrial and/or endothelial health to reduce patient burden." #MECFS #LongCovid https://www.nature.com/articles/s41467-026-75725-y
