Moreover, NFIL3 levels in the serum, liver, and small intestine were significantly reduced in the DFG, DFSG, and SG groups, compared with those in the MG group (p < 0.05 and p < 0.01), but no significant differences were observed among these three groups (Figures 4A–C). Here, NFIL3 is linked to myasthenia gravis.
