Both the cellular isoform of fibronectin and collagen type III are synthesized by fibroblasts in damaged tissue, and L. interrogans has been shown to adhere to fibronectin made by cultured fibroblasts [20].
The key event of prion amplification is the conversion of the cellular isoform of the prion protein (PrPC) into the pathogenic isoform (PrPSc).
This polyclonal antiserum does not distinguish between the protease-sensitive cellular isoform of the prion protein, PrPc, and the protease-resistant disease-specific isoform, PrPSc, in biochemical extracts.
Classical scrapie is a naturally occurring transmissible spongiform encephalopathy of sheep and goats characterized by cellular accumulation of abnormal isoforms of prion protein (PrPSc) in the central nervous system and the follicles of peripheral lymphoid tissues.
The common hypothesis is, that the amplification of PrPSc is achieved by the conversion of the α-helical dominated cellular isoform PrPC into β-sheet rich and insoluble PrPSc while PrPSc acts as template and catalyst for PrPC conversion [1].
Creutzfeldt-Jakob disease (CJD) is a lethal transmissible neurodegenerative disease caused by an abnormal isoform of prion protein (PrPSc), which is converted from the normal cellular isoform (PrPC) [ 1].
Cellular levels of NO are controlled by several isoforms of nitric oxide synthase (NOS): neuronal (nNOS, NOS1), inducible (iNOS, NOS2), and endothelial (eNOS, NOS3).
The cellular function for isoforms of the NHS protein is yet to be defined.
Research has mainly focussed upon NO production by isoforms of NO synthase (NOS).
In addition to GLS expression being regulated by cellular environment, the effects of diagnosis and glucose on expression varied by exon and may be isoform-specific.
