Several inflammatory biomarkers apart from CRP, like serum Cystatin C and transtyrectin (Keizman et al., 2009), serum‐soluble CD14 (Beers et al., 2020), and serum apokines (Nagel et al., 2017), were found to be raised in ALS patients compared with the HCs. Here, CD14 is linked to amyotrophic lateral sclerosis.
