When looking at the unadjusted p value, 26 molecules were significantly altered in the ALS group: interleukin (IL)‐15, IL‐16, and Aβ1‐40 were downregulated, whereas the levels of the aforementioned markers, other interleukins, and several cytokines were higher in disease samples (Figs S2 and S3A,B). This evidence concerns the gene IL16 and amyotrophic lateral sclerosis.
