Oxygen requirements of prions
WebAbstract. Prions, a self-templating amyloidogenic state of normal cellular proteins such as PrP, have been identified as the basis of a number of disease states, particularly diseases of the nervous system. This finding has led to the notion that protein aggregation, namely prionogenic aggregates and amyloids, is primarily harmful for the organism. WebClassic CJD characteristics, as compared to variant CJD, are presented in the table below. *An abnormal signal in the posterior thalami on T2- and diffusion-weighted images and fluid-attenuated inversion recovery sequences on brain magnetic resonance imaging (MRI); in the appropriate clinical context, this signal is highly specific for vCJD.
