The misfolding, aggregation and accumulation of specific proteins is the overarching concept in protein misfolding disorders (PMDs). The microtubule associated protein tau is known to form insoluble filaments known as neurofibrillary tangles (NFTs) composed of hyperphosphorylated tau (pTau) found in a subset of PMDs called tauopathies, such as Alzheimer’s disease (AD) and chronic traumatic encephalopathy (CTE), among others. Misfolded tau engenders a structurally alternative intermediate conformation that is prone to aggregate having amyloidogenic properties. Formation of amyloids, such as tau aggregates, is proposed to follow a nucleation-polymerization model where misfolded, soluble oligomeric seeds can trigger native proteins to misfold and …
