Strain Description
The TNFRSF9 gene (also known as 4-1BB or CD137) encodes a protein belonging to the tumor necrosis factor receptor (TNFR) superfamily. This receptor promotes T cell clonal expansion, survival, and effector functions, and modulates CD28 co-stimulation to enhance Th1-type immune responses. TRAF adaptor proteins can bind to it and transmit signals that activate NF-kappaB. Many immune cell types express TNFRSF9, including activated NK cells, NKT cells, B cells, eosinophils, basophils, mast cells, neutrophils, mature Tregs, activated monocytes, and dendritic cells. Additionally, TNFRSF9 may be expressed in non-immune cell types such as endothelial cells, neurons, astrocytes, and microglia. TNFRSF9 plays roles in innate and adaptive immunity, including cancer immunology and autoimmune diseases [1]. Due to its broad expression profile and immune response functions, 4-1BB is a potential target for cancer and immunotherapy. In recent years, research on second-generation 4-1BB agonists has been expanding, with various strategies being implemented to overcome the liver toxicity and efficacy limitations of the first generation [2-3].
The hu4-1BB(TNFRSF9) mouse is a humanized model. The sequence encoding the endogenous extracellular domain of the mouse Tnfrsf9 is replaced in situ with the sequence encoding the human TNFRSF9 extracellular domain. This model can be used for studies on cancer immunology and autoimmune diseases, as well as for the development, screening, and evaluation of 4-1BB agonists in preclinical research.
