Scientists have discovered a potential reason why melanoma doesn’t always respond to certain drugs.
For some advanced melanoma patients, immune checkpoint inhibitors — a kind of immunotherapy that pushes the immune system to attack tumors — can lead to long-term remission. But for many patients, the drugs don’t work. Now, scientists at Swiss Federal Institute of Technology in Lausanne studying a mouse model of melanoma have discovered that “bad immune cells” might be limiting how well the drugs work. Their findings were published this week in Science Translational Medicine.
