LTF and amyotrophic lateral sclerosis: In accordance to Dor et al. [68], we detected lactotransferrin (LTF), lipocalin-1 (LCN1), serum albumin (ALB), lysozyme C (LYZ), and immunoglobulin heavy constant alpha (IGHA) as the five most abundant TF proteins in our control subjects, as well as in the ALS patients (Figure S9, Data S4).
