Comparing 2 hypotheses side-by-side
Genetically modified microglia overexpressing mitochondrial export machinery package healthy mitochondria into extracellular vesicles with neuron-specific targeting ligands.
Gut dysbiosis leads to LPS translocation, triggering intestinal and systemic inflammation via TLR4/MyD88/NF-κB signaling, promoting α-synuclein pathology. The peripheral gut barrier is the most viable intervention point, though CNS microglial TLR4 activation remains mechanistically tenuous. Best therapeutic approach: zonulin antagonists (larazotide) for gut barrier restoration combined with NLRP3 inflammasome inhibition rather than direct TLR4 blockade.
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
