Similarly, CAT activity was increased in BV-2 cells treated with ALS IgG (121.72 ± 6.14 U/mg, that was 1.5-fold higher as compared with the control group, 82.78 ± 1.18 U/mg, p < 0.01, and 1.2-fold higher as compared to cells treated with control IgG, 100.85 ± 5.41 U/mg, but with no statistical significance; Figure 2C). Here, CAT is linked to amyotrophic lateral sclerosis.
