NOT RECOMMENDED. Critical safety contraindications: PU.1 knockout is embryonic lethal in mice; PU.1 haploinsufficiency in humans causes neutropenia and immunodeficiency. The hypothesis contains a mechanistic paradox: Keren-Shaul et al. (PMID:29445926) demonstrates PU.1 directly regulates TREM2 expression and is REQUIRED for DAM formation. Degrading PU.1 would eliminate the protective DAM state entirely, contradicting therapeutic intent. PROTAC chemistry is validated (ARV-471, ARV-110), but this
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.
