Strain Description
The interleukin-1 receptor accessory protein, encoded by IL1RAP, serves as a critical co-receptor for multiple cytokine systems, notably the interleukin-1 (IL-1) family. This broadly expressed protein is essential for the formation of functional receptor complexes for IL-1, IL-33, and IL-36, thereby mediating downstream signaling pathways that drive innate immunity and inflammatory responses [1-5]. Acting as a co-receptor, IL1RAP interacts with ligand-binding receptors such as IL1R1, IL33R (IL1RL1/ST2), and IL36R, initiating MyD88-dependent signal transduction that culminates in the expression of pro-inflammatory genes and cytokines [1-5]. IL1RAP expression is observed across a range of cell types, including immune, endothelial, epithelial, and neuronal cells, as well as various tumor lineages. Perturbations in IL1RAP expression or genetic variants have been implicated in a spectrum of pathologies, encompassing inflammatory diseases such as asthma, autoimmune disorders, neurodegenerative conditions such as Alzheimer's disease, and malignancies including acute myeloid leukemia, Ewing sarcoma, pancreatic cancer, and gastric adenocarcinoma [2-4]. Consequently, IL1RAP represents a target of intense investigation for therapeutic interventions in cancer and inflammatory diseases [4-5].
B6-hIL1RAP mice are humanized models generated using gene editing technology. They are constructed by integrating the protein-coding sequence (CDS) encoding the extracellular domain of human IL1RAP protein and the intracellular domain of mouse IL1RAP protein, along with the 3'UTR of the mouse Il1rap gene, into a specific site within the mouse Il1rap gene. This process retains the endogenous gene sequence encoding the mouse signal peptide. Homozygous B6-hIL1RAP mice are viable and fertile. This model can be used for studying the pathological mechanisms and therapeutic approaches of cancer and inflammatory diseases, and for the development of IL1RAP-targeted drugs.

Strain Strategy
Figure 1. Gene editing strategy of B6-hIL1RAP mice. The partial coding sequence of exon 2 to partial intron 2 sequence of the mouse Il1rap gene was replaced with an "Extracellular domain of Human IL1RAP CDS-Mouse Il1rap CDS-3'UTR of Mouse Il1rap-WPRE-BGH pA" cassette. The murine signal peptide of the mouse IL1RAP protein was preserved.
