MSRV-Env is a full and highly potent agonist of human TLR4.
MSRV-Env has strong pro-inflammatory properties in vitro and in vivo.
MSRV-Env impairs human OPC maturation to myelinating oligodendrocytes.
GNbAC1 inhibits MSRV-Env in all models investigated.
GNbAC1 may offer a new therapeutic option for MS treatment.
