RESUMO
Sera from patients with systemic lupus erythematosus (SLE) have been tested for antibody to a human neuronal cell line, SK-N-SH, derived from a metastatic neuroblastoma. With a complement-dependent 51Cr-release cytotoxicity assay, 75% of SLE sera had antineuronal activity mediated by IgM antibody. Most of the sera containing this IgM neurocytotoxic antibody were also cytotoxic to the human glial cell lines A-172 and U-118MG. The sera did not mediate complement-dependent 51Cr release when tested against normal human fibroblasts or peripheral blood lymphocytes. IgG antineuronal antibody was detected in 17% of SLE sera by an antibody-dependent, cell-mediated cytotoxicity assay with SK-N-SH cells as targets.
