Densitometry indicated that the relative intensity of GLT1 in sALS astrocytes was significantly lower (70%) than that of non-ALS astrocytes (Figures 2E–2G) in the center domain, while in the distal domain the relative intensity of GLT1 had no difference between the groups (Figures 2E–2G). Here, SLC1A2 is linked to amyotrophic lateral sclerosis.
