Amyotrophic lateral sclerosis: interleukin-6 levels in cerebrospinal fluid.
Recent observations indicate that antibodies to gangliosides are found in many patients with amyotrophic lateral sclerosis (ALS). If antigen-antibody complexes occur in ALS, elevations of cytokine levels might be expected, among them the cytokine interleukin-6 (IL-6). IL-6 is secreted by activated monocytes and other cell types and is an important mediator of the inflammatory response. We have measured cerebrospinal fluid (CSF) IL-6 levels in patients with ALS and compared them with those in psychiatric and neurodegenerative disorders not believed to be due to immune disorders of the central nervous system. We found no significant differences in CSF IL-6 levels between these groups.
