The LBFGS Quasi-Newtonian Method for Molecular Modeling Prion AGAAAAGA Amyloid Fibrils [PDF]

, 2012
Experimental X-ray crystallography, NMR (Nuclear Magnetic Resonance) spectroscopy, dual polarization interferometry, etc are indeed very powerful tools to determine the 3-Dimensional structure of a protein (including the membrane protein); theoretical ...

Clinical–Radiological Spectrum of Cerebral Amyloid Angiopathy‐Related Inflammation

Annals of Neurology, EarlyView.
Objective To identify clinical and radiological features of cerebral amyloid angiopathy‐related inflammation (CAA‐ri), and compare these features with those of sporadic CAA, to improve the understanding, diagnosis, and clinical care of CAA‐ri. Methods We retrospectively reviewed routine clinical data from 37 patients with CAA‐ri and 158 patients with ...

A systematic investigation of production of synthetic prions from recombinant prion protein [PDF]

, 2015
According to the protein-only hypothesis, infectious mammalian prions, which exist as distinct strains with discrete biological properties, consist of multichain assemblies of misfolded cellular prion protein (PrP).

Anatomical Associations Between Focal Mitochondrial Metabolism and Patterns of Neurodegeneration in Amyotrophic Lateral Sclerosis

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a very specific neuroimaging signature, but the molecular underpinnings of the strikingly selective anatomic involvement have not elucidated to date. Accordingly, a large neuroimaging study was conducted with 258 participants to evaluate associations between patterns of neurodegeneration and focal ...

Distinct patterns of prion strain deposition and toxicity in a novel whole brain organotypic slice culture system

Scientific Reports
Prion diseases are fatal transmissible neurodegenerative diseases that affect many mammals, including humans, caused by the templated misfolding of the prion protein.

Aerosols transmit prions to immunocompetent and immunodeficient mice. [PDF]

PLoS Pathogens, 2011
Prions, the agents causing transmissible spongiform encephalopathies, colonize the brain of hosts after oral, parenteral, intralingual, or even transdermal uptake. However, prions are not generally considered to be airborne.

Molecular Dynamics Studies on 3D Structures of the Hydrophobic Region PrP(109-136) [PDF]

, 2013
Prion diseases caused by the conversion from a soluble normal cellular prion protein into insoluble abnormally folded infectious prions, are invariably fatal and highly infectious degenerative diseases that affect a wide variety of mammalian species. The

The Phenotypic Spectrum of Sporadic Creutzfeldt‐Jakob Disease Cortical Subtype

Annals of Neurology, EarlyView.
Objective The objective of this study was to characterize the phenotypic spectrum of the rare sporadic Creutzfeldt‐Jakob disease cortical subtype (sCJDMM/MV2C) in a large multicentric autopsy cohort. Methods We evaluated clinical histories, biofluid markers, brain diffusion‐weighted (DW)‐magnetic resonance imaging (MRI), and electroencephalogram (EEG ...

Prions Ex Vivo: What Cell Culture Models Tell Us about Infectious Proteins

International Journal of Cell Biology, 2013
Prions are unconventional infectious agents that are composed of misfolded aggregated prion protein. Prions replicate their conformation by template-assisted conversion of the endogenous prion protein PrP.
