| 2 | Human Endogenous Retrovirus Type W Envelope from Multiple Sclerosis Demyelinating Lesions Shows Unique Solubility and Antigenic Characteristics显示文摘In multiple sclerosis(MS),human endogenous retrovirus W family(HERV-W)envelope protein,pHERV-W ENV,limits remyelination and induces microglia-mediated neurodegeneration.To better understand its role,we examined the soluble pHERV-W antigen from MS brain lesions detected by specific antibodies.Physico-chemical and antigenic characteristics confirmed differences between pHERV-W ENV and syncytin-1.pHERV-W ENV monomers and trimers remained associated with membranes,while hexamers self-assembled from monomers into a soluble macrostructure involving sulfatides in MS brain.Extracellular hexamers are stabilized by internal hydrophobic bonds and external hydrophilic moieties.HERV-W studies in MS also suggest that this diffusible antigen may correspond to a previously described highmolecular-weight neurotoxic factor secreted by MS B-cells and thus represents a major agonist in MS pathogenesis.Adapted methods are now needed to identify encoding HERV provirus(es)in affected cells DNA.The properties and origin of MS brain pHERV-W ENV soluble antigen will allow a better understanding of the role of HERVs in MS pathogenesis.The present results anyhow pave the way to an accurate detection of the different forms of pHERV-W ENV antigen with appropriate conditions that remained unseen until now. | Benjamin Charvet Justine Pierquin Joanna Brunel Rianne Gorter Christophe Que´tard Branka Horvat Sandra Amor Jacques Portoukalian Herve´Perron | 2021 | Virologica Sinica2021，36，5： | 1 |
| 3 | Brain antigens in functionally distinct antigen-presenting cell populations in cervical lymph nodes in MS and EAE显示文摘Drainage of central nervous system(CNS) antigens to the brain-draining cervical lymph nodes(CLN) is likely crucial in the initiation and control of autoimmune responses during multiple sclerosis(MS). We demonstrate neuronal antigens within CLN of MS patients. In monkeys and mice with experimental autoimmune encephalomyelitis(EAE) and in mouse models with non-inflammatory CNS damage, the type and extent of CNS damage was associated with the frequencies of CNS antigens within the cervical lymph nodes. In addition, CNS antigens drained to the spinal-cord-draining lumbar lymph nodes. In human MS CLN, neuronal antigens were present in pro-inflammatory antigen-presenting cells(APC), whereas the majority of myelincontaining cells were anti-inflammatory. This may reflect a different origin of the cells or different drainage mechanisms. Indeed, neuronal antigen-containing cells in human CLN did not express the lymph node homing receptor CCR7, whereas myelin antigen-containing cells in situ and in vitro did. Nevertheless, CLN from EAE-affected CCR7-deficient mice contained equal amounts of myelin and neuronal antigens as wild-type mice. We conclude that the type and frequencies of CNS antigens within the CLN are determined by the type and extent of CNS damage. Furthermore, the presence of myelin and neuronal antigens in functionally distinct APC populations within MS CLN suggests that differential immune responses can be evoked. | Marloes van Zwam Ruth Huizinga Marie-José Melief Annet F.Wierenga-Wolf Marjan van Meurs Jane S.Voerman Knut P.H.Biber Hendrikus W.G.M.Boddeke Uta E.Hopken Christian Meisel Andreas Meisel Ingo Bechmann Rogier Q.Hintzen Bert A.‘t Hart Sandra Amor Jon D.Laman Leonie A.Boven | 2016 | 世界最新医学信息文摘2016，16，11： | 0 |
