Current therapeutic interventions are symptomatic but fail to stop disease progression. Stem cell-based regenerative strategies have been recognized as potential disease-modifying treatments. Mitochondria-augmented stem cell therapy offers a new mechanism for the correction of cellular bioenergetic deficits. Through genetic manipulations or preconditioning protocols, mesenchymal stem cells and induced pluripotent stem cells are engineered to enhance mitochondrial function and transfer. The engineered cells enable delivery of functional mitochondria into damaged neurons through tunneling nanotubes or extracellular vesicles, promoting ATP production, inhibiting reactive oxygen species, and restoring mitophagy.

Gut dysbiosis and its metabolites modulate barrier permeability and cause gastrointestinal tract (GIT) inflammation, which is followed by an increase in pro-inflammatory cytokines, immune cell infiltration into the brain, and vagus nerve dysfunction, resulting in neuroinflammation and neuronal defects in the brain, as well as some other behavioral defects.
