🧪 Overview

Neuronal activity induces CDK5-dependent tau phosphorylation and packaging into exosomes. Selective CDK5 inhibition prevents loading and reduces trans-synaptic tau spreading. Requires development of selective CDK5 inhibitors (not pan-CDK inhibitors like dinaciclib).

⚖️ Evidence

⚖️ Evidence Matrix3 supports3 contradicts
Supports
p25/CDK5 hyperactivity drives tau hyperphosphorylation in AD
Supports
Exosome-mediated tau spread confirmed in human CSF
Supports
Tau propagation requires neuronal activity
Contradicts
Dinaciclib is pan-CDK inhibitor (CDK1/2/5/9), not selective CDK5 inhibitor
Contradicts
CDK5 is essential for memory consolidation - chronic inhibition may impair cognition
Contradicts
Narrow therapeutic window is prohibitive
