  • JAK-STAT signaling studies: Dissect IL-9–induced STAT activation and downstream gene programs.

Strain Description

The hIL9R Mouse Model​ carries a targeted knock-in of the human IL9RA​ gene at the endogenous mouse locus. It replaces the murine Il9ra​ coding sequence while preserving native promoters and regulatory elements. This ensures physiological expression of functional human IL-9RA (IL-9 receptor α chain) in the same cell types where the endogenous gene is normally expressed, including T cells, mast cells, eosinophils, and epithelial cells.

In this hIL9R model, IL-9R signaling through JAK1/JAK3 activates STAT1, STAT3, and STAT5 to regulate genes involved in survival, proliferation, and cytokine production. In allergic asthma and ulcerative colitis, IL-9R drives mucus hypersecretion, mast cell activation, and barrier dysfunction. Dysregulated IL-9R signaling also contributes to autoimmune demyelination and certain hematologic malignancies.

This humanized IL9R model​ allows therapeutic antibodies such as anti–IL-9R monoclonal antibodies to bind human IL-9RA in vivo. It thus provides a translational platform for evaluating IL-9/IL-9R–targeted drugs, studying Th9 cell biology, and modeling human IL-9R–associated inflammatory diseases that conventional models cannot replicate.

FAQ

Game-changing benefits?

While competitors highlight germline efficiency gains, shorter timelines and enhanced 3Rs animal welfare benefits for their technologies, these are merely incremental improvements over traditional approaches. In sharp contrast, our proprietary technology delivers fully pure, homogeneous lineages—every single cell of the mice is derived exclusively from totipotent ES cells, with guaranteed 100% germline transmission efficiency. To experience these unparalleled benefits firsthand, enquire about your custom mouse model project with us or order embryos for in-house validation at your facility.
