Constitutive neuronal AMPK activation via AAV9-Synapsin-AMPKα1(T172D) tests whether restoring AMPK activity reverses microglial inflammation after it is established. Requires post-onset rescue design (inducible system) rather than pre-symptomatic prevention to answer the therapeutic reversibility gap. Acts upstream of lipid synthesis to normalize the neuronal-microglial lipid transfer axis.
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.
