Do astrocytes functionally express TRIM46, and can PKCα phosphorylate it to drive TNT formation?
PARTIALLY ADDRESSED
The P2X7 hypothesis relies on TRIM46-mediated actin polymerization in astrocytes, but TRIM46 is established as neuronal-specific for microtubule organization. This fundamental molecular gap undermines the proposed mechanism and requires direct validation in astrocytic cultures.
