  1. Topical Collection on Genetics


Neurodegenerative diseases, including Alzheimer’s disease and Parkinson’s disease, are characterized by the abnormal aggregation of a small number of intracellular proteins, with tau and α-synuclein being the most commonly affected. Until recently, the events leading to aggregate formation were believed to be entirely cell-autonomous, with protein misfolding occurring independently in many cells. It is now believed that protein aggregates form in a small number of brain cells, from which they propagate intercellularly through templated recruitment, reminiscent of the mechanisms by which prions spread through the nervous system.

Brain homogenates from human tauopathies were intracerebrally injected into mice transgenic for human wild-type tau, where they induced the formation of silver-positive tau inclusions. Some inclusions also formed following injection into wild-type mice. This work revealed the likely existence of distinct conformers (or strains) of aggregated 4R tau, since the light microscopic hallmark lesions of AGD, PSP, and CBD were recapitulated following injection.PubMedPubMedCentralGoogle Scholar

Two strains were produced in cells that gave rise to distinct pathologies in the brains of presymptomatic mice transgenic for human mutant P301S tau. Immunopurified tau from these mice recreated the original strains in culture. When this system was used to isolate tau strains from human tauopathies, different diseases were associated with different sets of strains. Google Scholar
