Putative pathways of deleterious tau and α-synuclein interactions. Interaction of tau and αsyn may promote pathogenesis via distinct mechanisms. 1. αSyn may block the normal interaction between tau and tubulin by directly binding to tau and tubulin and thereby interfering with tau physiological function. 2. αSyn could recruit kinases and promote the hyperphosphorylation of tau. 3. αSyn may also catalyze tau polymerization and trigger the formation of tau/αsyn co-oligomers. 4. Finally, αsyn oligomers or fibrils may seed tau fibrillization and thereby initiate and propagate tauopathy.
