Patent ID: 7666420

Claim:
A composition comprising: at least one selected from the group consisting of: anti-multiple sclerosis-associated retrovirus/human endogenous retrovirus-W envelope protein soluble fraction antibodies (anti-MSRV/HERV-W Env-SU antibodies), and mixtures of anti-MSRV/HERV-W Env-SU antibodies and anti-toll-like receptor 4 antibodies (anti-TLR4 antibodies) capable of binding specifically to the TLR4 receptor for the soluble fraction of the multiple sclerosis-associated retrovirus/human endogenous retrovirus-W envelope protein (MSRV/HERV-W Env protein), and a pharmaceutically acceptable carrier; wherein the soluble fraction of the MSRV/HERV-W Env protein comprises the sequence set forth in SEQ ID NO:3 and the antibody or mixture of antibodies inhibits an interaction between the soluble fraction of the MSRV/HERV-W Env protein and the TLR4 receptor.
