Pubmed ID	23836485
Year	2013
Title	Human Endogenous Retrovirus Type W Envelope Protein Inhibits Oligodendroglial Precursor Cell Differentiation

Results of multiple sclerosis :

Expression	up-regulation
Risk type	Disease risk
Result	We demonstrated that the ENV protein is present in close proximity to TLR4-expressing oligodendroglial precursor cells adjacent to multiple sclerosis lesions. Human and rat oligodendroglial precursor cells expressed TLR4, and the ENV-mediated activation of TLR4 led to the induction of proinflammatory cytokines and inducible nitric oxide synthase as well as the formation of nitrotyrosine groups and a subsequent reduction in myelin protein expression.Interpretation: Our findings suggest that ENV-mediated induction of nitrosative stress via activation of TLR4 results in an overall reduction of the oligodendroglial differentiation capacity, thereby contributing to remyelination failure.Therefore, pharmacological or antibody-mediated inhibition of ENV may prevent the blockade of myelin repair in the diseased or injured central nervous system.
Mechanism/Pathway	Human and rat oligodendroglial precursor cells expressed TLR4, and the ENV-mediated activation of TLR4 led to the induction of proinflammatory cytokines and inducible nitric oxide synthase as well as the formation of nitrotyrosine groups and a subsequent reduction in myelin protein expression
