This study investigates the role of tubulin-alpha4a (Tuba4a) polyglutamylation in tauopathies. Researchers generated a Knockin mouse model with mutations preventing polyglutamylation of Tuba4a. These mice exhibited reduced binding of tau and GSK3 kinase to neuronal microtubules, leading to decreased tau phosphorylation. Crossbreeding with a human tauopathy model reversed tau hyperphosphorylation, oligomerization, and microglial activation, highlighting tubulin polyglutamylation as a potential therapeutic target in tauopathies.
Preventing Tuba4a polyglutamylation reduces tau hyperphosphorylation and microglial activation, suggesting a novel therapeutic approach for tauopathies.
Tuba4aΔpolyGlu Knockin mouse model with point mutations abolishing polyglutamylation of Tuba4a, developed to study the impact on tau pathology.
