title: [Transfer of multiple sclerosis into SCID mice].
abstract: Successful transfer of multiple sclerosis (MS) into severe combined immunodeficient (SCID) mice by intracisternal injection of cerebrospinal fluid (CSF) cells from six of 15 patients at exacerbation has been reported. The relative expression of mRNA for cytokines in demyelinated lesions from SCID-hu-MS by a semiquantitative reverse transcriptase-polymerase chain reaction analysis revealed marked increase in expression of mRNAs for TNF-alpha and IL-6. This result raised the possibility that these cytokines played an important role in the demyelinating process in SCID-hu-MS. To test whether or not an antibody (Ab) to murine TNF-alpha has a preventive effect on transfer of MS into SCID mice, intracisternal injection of CSF cells from two patients at exacerbation together with anti-murine TNF-alpha Ab was performed, and we observed effective prevention of transfer. In addition, we also found an Ab to human CD3 (OKT3) to have a preventive effect. The former result suggests that control of TNF-alpha may be effective in treatment of MS and the latter suggests that MS is a T cell-mediated disease.
