AA467197-flox Mouse

Aa467197, also known as Nmes1 (Normal Mucosa of Esophagus-Specific gene 1), is a novel regulator of mucosal healing. It influences the macrophage response to the tissue remodeling cytokine IL-4 and is thus involved in the tissue remodeling process following damage, which is crucial in preventing immune-mediated diseases [1].

In murine models, ablation of Nmes1 (Aa467197) led to decreased intestinal regeneration during the recovery phase of colitis, while enhancing parasitic egg clearance and reducing fibrosis during advanced stages of Schistosoma mansoni infection. These changes were associated with alterations in CX3CR1+ macrophages, known for their wound-healing potential in the inflamed colon [1]. Additionally, in a study on food allergies in mice, Weighted Gene Co-Expression Network Analysis showed a positive correlation between Aa467197 expression and either nanoplastics exposure or ovalbumin sensitization, suggesting its role in the modulation of gene expression related to food allergies [2].

In conclusion, Aa467197 (Nmes1) plays an essential role in mucosal healing processes, affecting intestinal regeneration and responses to certain infections. Gene-knockout mouse models have revealed its significance in colitis and Schistosoma mansoni-related disease conditions. Moreover, its potential role in food allergy-related gene expression modulation indicates its importance in understanding and potentially treating multiple disease areas. [1,2]
