Used in immunological research to study the function and signaling of the CCR8 receptor, which plays a role in T cell migration and immune regulation. This cell line is particularly valuable for screening and evaluating potential drug candidates targeting CCR8, such as antagonists or antibodies, in the development of therapies for inflammatory diseases, autoimmune disorders, and cancer immunotherapy. The expression of CCR8 in a stable HEK293 host allows consistent and reproducible results in chemotaxis assays, ligand binding studies, and signal transduction analysis.
