We found that transferring WT Treg cells into the CD4-Cre+/TgMettl14FL/FL conditional knockout mice attenuated the colitis phenotype as assessed by decreased colonic weight-to-length ratio (Figure 4A) and decreased inflammatory cell infiltration (Figure 4B) compared with untreated CD4-Cre+/TgMettl14FL/FL conditional knockout mice. The gene discussed is CD4; the disease is colitis.
