Chemokine receptor desensitization in tumor-bearing mice.


We found that the murine breast cancer cell line 4T1 constitutively produced several chemokines capable of recruiting T cells. Additionally, supernatants from the tumor cell line mediated chemotaxis of T cells in a pertussis toxin-sensitive manner, indicating that these chemokines were functional. However, we also found an impaired chemotactic ability of… (More)
