• The initiation of tissue remodeling following damage is a critical step in preventing the development of immune‐mediated diseases. Several factors contribute to mucosal healing, leading to innovative therapeutic approaches for managing intestinal disorders. However, uncovering alternative targets and gaining mechanistic insights are imperative to enhance therapy efficacy and broaden its applicability across different intestinal diseases. Here we demonstrate that Nmes1, encoding for Normal Mucosa of Esophagus‐Specific gene 1, also known as Aa467197, is a novel regulator of mucosal healing. Nmes1 influences the macrophage response to the tissue remodeling cytokine IL‐4 in vitro. In addition, using two murine models of intestinal damage, each characterized by a type 2‐dominated environment with contrasting functions, the ablation of Nmes1 results in decreased intestinal regeneration during the recovery phase of colitis, while enhancing parasitic egg clearance and reducing fibrosis during the advanced stages of Schistosoma mansoni infection. These outcomes are associated with alterations in CX3CR1+ macrophages, cells known for their wound‐healing potential in the inflamed colon, hence promising candidates for cell therapies. All in all, our data indicate Nmes1 as a novel contributor to mucosal healing, setting the basis for further investigation into its potential as a new target for the treatment of colon‐associated inflammation. Nmes1 is a novel regulator of intestinal inflammation. In two models of intestinal inflammation, each characterized by a type 2‐dominated environment with contrasting functions, Nmes1 in CX3CR1+ macrophages promotes healing during the remission phase of dextran sodium sulfate‐induced colitis while preventing parasitic egg clearance and inducing fibrosis during chronic Schistosoma mansoni infection.
