IL-4, IL-7, IL-17, eotaxin/CCL11, FGF-2, G-CSF, and PDGF-BB levels were higher in patients with ALS than patients with ONDs; of these, IL-4, IL-17, FGF-2, and G-CSF levels were elevated compared with patients with MMN as well (table 3; figure 1). This evidence concerns the gene IL4 and amyotrophic lateral sclerosis.
