Abstract

Process for in vitro production of a culture or cell line infected by a viral strain associated with multiple sclerosis (MS), according to which a body sample is taken from an individual suffering from MS, said sample is cultivated in a culture medium which promotes the growth of infected cells to obtain a culture of primary infected cells, and a sample of the culture of primary cells or of a subculture of the latter is cultivated in series, that is to say by successive passages, in said culture medium to obtain the culture or cell line infected by a virus associated with MS, which comprises a procedure in which the culture medium also contains a beta anti-interferon antibody or an antibody which is directed against an antigenically close molecule, the antibody playing an inhibiting role in viral expression and allowing long-lasting expression and propagation of the viral strain in the culture or cell line.
