The inflammatory response in amyotrophic lateral sclerosis (ALS) is well documented but the underlying cellular mechanisms have not been fully elucidated. We report that microglia isolated from the mutant human superoxide dismutase 1 (SOD1) G93A transgenic mouse model of ALS have an increased response to the inflammatory stimulus, lipopolysaccharide. Cell surface area and F4/80 surface marker, both indicators of cell activation, are increased relative to transgenic wild-type human SOD1 microglia. Monocyte chemoattractant protein-1, known to be increased in ALS, is produced at three-fold higher levels by SOD1 G93A than by wild-type human SOD1 microglia, under activating conditions. This novel finding implicates ALS microglia as a source of the increased monocyte chemoattractant protein-1 levels detected in ALS patients and in the ALS mouse model.
