The prion-like transmission of tau oligomers exosomes.

The conversion and transmission of misfolded proteins established the basis for the prion concept. Neurodegenerative diseases are considered "prion-like" disorders that lack infectivity. Among them, tauopathies are characterized by the conversion of native tau protein into an abnormally folded aggregate.

Morphological, Pathogenic, and Genetic Comparisons of Colletotrichum graminicola Isolates from Poaceae.

Isolates of Colletotrichum graminicola from annual blue grass and creeping bent grass were investigated for their morphological characteristics, host specificity, and genetic relatedness. One isolate from maize and one from sorghum (C. sublineolum) were included for comparison.
