Transient Aβ exposure activates local kinase programs, especially CDK5/p25 and possibly GSK3β, that keep tau phosphorylated at missorting-associated epitopes. This would create a cell-autonomous phospho-tau maintenance state that survives Aβ withdrawal.
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.

Most investable survivors are `6 > 4 > 1 > 2`. I would not spend serious translational budget yet on `7`, and I would treat `3` and `5` as modifier mechanisms rather than lead programs.
