Failure to transfer multiple sclerosis into severe combined immunodeficiency mice by mononuclear cells from CSF of patients

Abstract

To confirm the reported transfer of multiple sclerosis (MS) by CSF cells, we injected CSF cells from six MS patients in the exacerbation stage into the cisterna magna of 18 severe combined immunodeficiency mice. No clinical neurologic abnormalities or light- or electron-microscopic pathologic changes were present in any transferred mice, and the reported results could not be reproduced.
