De novo prions
Prions are responsible for a heterogeneous group of fatal neurodegenerative diseases. They occur in three forms - sporadic, genetic, or acquired - and involve non-covalent post-translational modifications of the cellular prion protein (PrP(C)). Prions (PrP(Sc)) are characterized by their infectious properties and intrinsic ability to act as a template, converting the normal, physiological PrP(C...
متن کاملDe Novo Generation of Infectious Prions In Vitro Produces a New Disease Phenotype
Prions are the proteinaceous infectious agents responsible for Transmissible Spongiform Encephalopathies. Compelling evidence supports the hypothesis that prions are composed exclusively of a misfolded version of the prion protein (PrP(Sc)) that replicates in the body in the absence of nucleic acids by inducing the misfolding of the cellular prion protein (PrP(C)). The most common form of human...
متن کاملCellular factors important for the de novo formation of yeast prions.
Prions represent an unusual structural form of a protein that is 'infectious'. In mammals, prions are associated with fatal neurodegenerative diseases such as CJD (Creutzfeldt-Jakob disease), while in fungi they act as novel epigenetic regulators of phenotype. Even though most of the human prion diseases arise spontaneously, we still know remarkably little about how infectious prions form de no...
متن کاملDe-Novo Presentation of Histoid Leprosy on an Unusual Site
Histoid Leprosy (HL) is a rare variant of Lepromatous Leprosy, occurring in long-standing cases, mostly in a background of acquired drug resistance. Patients usually present with sudden onset multiple nodules and plaques, most often involving the skin and subcutaneous tissue of trunk and lower limbs. Here we report an unusual case of de novo (without any history of prior anti-leprotic therapy) ...
متن کاملOn solving possibilistic multi- objective De Novo linear programming
Multi-objective De Novo linear programming (MODNLP) is problem for designing optimal system by reshaping the feasible set (Fiala [3] ). This paper deals with MODNLP having possibilistic objective functions coefficients. The problem is considered by inserting possibilistic data in the objective functions coefficients. The solution of the problem is defined and established under the using of effi...
