Tumor extracellular vesicles carrying phosphatidylserine activate microglia via TREM2, enhancing neuroprotective functions. This is interesting discovery biology but not trial-ready. Requires characterization of PS exposure, EV cargo composition, and demonstration that EVs directly mediate the cystatin-C effect.
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.
