Comparing 2 hypotheses side-by-side
Some tau species are transferred between neurons but remain non-pathogenic because they stay trapped in degradative endosomal routes. Seed-competent tau either escapes into cytosol or traffics through compartments that expose it to soluble tau substrate.
## Mechanistic Overview Mitochondrial-Lysosomal Contact Site Engineering starts from the claim that modulating RAB7A within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The mitochondrial-lysosomal contact site (MLCS) represents a critical nexus for cellular quality control, particularly in post-mitotic neurons vulnerable to neurodegeneration. RAB7A, a small GTPase of the Ras superfamily, s

Seed-competent tau is likely defined by a compact beta-rich conformer exposing repeat-domain surfaces, a permissive PTM barcode, and packaging into vesicles or synaptic compartments that protect it fr...
Uptake is not seeding. The decisive experiment must compare matched tau species that enter neurons equally but differ in templating kinetics, persistence, and downstream neurotoxicity....
Clinically, the best product concept is a conformation- or PTM-selective antibody paired with CSF seed amplification or tau-PET enrichment. Broad tau lowering risks interfering with normal microtubule...
Ranked synthesis: conformer exposure is primary, PTM barcode is the strongest modulator, and vesicle context explains why some transferable tau remains non-pathogenic....
