Levels of cytokines in cerebrospinal fluid (CSF) of pediatric and adult spinal muscular atrophy (SMA) patients. The concentration (pg/ml) of levels of (A) IL-21, (B) IL-22, (C) IL-23, (D) IL-31, and (E) IL-33 were measured in the serum of pediatric (Ped.; circle, N = 21) and adult (Ad.; square, N = 13) SMA patients at baseline (T0 black) and after 6 months of nusinersen treatment (T6 white), and in healthy controls (Ad. CTR; gray triangle) by multiplex immuno assay. Data in the graphs are reported as mean ± SEM for each sample group. The before-after graphs contains the mean cytokine concentration obtained for each patient in the duplicate multiplex immunoassays reactions before and after 6 months of nusinersen treatment (T0 and T6). p > 0.05, Mann–Whitney test.
