CELF2 and Alzheimer disease: By comparing oligodendrocyte differential genes between DNT‐treated mice and AD mice (Figure 3E), we found that Pacrg, a gene related to Lewy body formation [32], was significantly downregulated, while Kcnip4, Celf2, Nrxn3, Kcnd2, and Pcdh11x were significantly upregulated.
