Abstract/OtherAbstract:
Multiple Sclerosis (MS) is considered to be an autoimmune disease with unknown cause and with immune system dysregulation. Among environmental factors, viruses are most often connected with the etiology of MS.Human Endogenous Retroviruses (HERVs) constitute 5-8% of human genomic DNA and have been detected as transcripts and proteins in the central nervous system (CNS) and peripheral blood, frequently in the context of neuroinflammation. The HERV-Fc1, which belongs to the HERV-H/F family, has received our attention largely because of the genetic association with MS.The authors studied the expression of a capsid (Gag) protein of HERV-H/F origin by flow cytometry in PBMCs from healthy controls and from MS patients with non-active or active disease. There was a significant increase in HERV-H/F Gag expression in CD4+ (P<0.001***) and CD8+ T lymphocytes (P<0.001***), and in monocytes (P=0.0356*) in PBMCs from MS patients with active disease. Furthermore, we have undertaken the first rigorous SYBR green-based absolute Q-PCR evaluation approach to quantify extracellular HERV-Fc1 RNA viral loads in plasma from MS patients and healthy controls. We have found a 4 fold increase in extracellular HERV-Fc1 RNA titers in patients with active MS as compared with healthy controls (P<0.001***). These findings strengthen the link between HERV-Fc1 and the pathology of MS. The cause and biological consequences of these differential expressions will be the subject of further investigation. HERV-Fc1 biology could be a compelling area for understanding the pathology of MS and possibly other autoimmune disorders.
