Abstract

Sporadic amyotrophic lateral sclerosis (sALS) is a progressive neuroinflammatory disease of spinal cord motor neurons of unclear etiology. Blood from 38 patients with sALS, 28 aged-match controls, and 25 Alzheimer's disease (AD) patients were evaluated and activated monocyte/macrophages were observed in all patients with sALS and AD; the degree of activation was directly related to the rate of sALS disease progression. Other parameters of T-cell activation and immune globulin levels showed similar disease associated changes. These data are consistent with a disease model previously suggested for AD, wherein systemic immunologic activation plays an active role in sALS.
