Scientists discover new immunosuppressive mechanism in brain cancer
The Wistar Institute assistant professor Filippo Veglia, Ph.D., and team, have discovered a key mechanism of how glioblastoma—a serious and often fatal brain cancer—suppresses the immune system so that the tumor can grow ...

Pan-cancer analysis uncovers a new class of promising CAR T–cell immunotherapy targets
Targeting anti-cancer therapy to affect cancer cells but not healthy cells is challenging. For chimeric antigen receptor (CAR) T–cell immunotherapy, where a patient's own immune cells are re-engineered to attack cancer ...

Newly discovered mechanism of T-cell control can interfere with cancer immunotherapies
Activated T cells that carry a certain marker protein on their surface are controlled by natural killer (NK) cells, another cell type of the immune system. In this way, the body presumably curbs destructive immune reactions.

Turning a tumor's 'shield' into a weapon against itself
Tumor cells are "cunning," according to Peter Yingxiao Wang. They have a nefarious way of evading the human immune responses that fight back against these cancerous invaders. Tumor cells express programmed death-ligand 1 ...
