The immune health future, today

Breaking the code of the immune system could provide a new fundamental way of understanding, treating, and preventing every type of disease. Penn Medicine is investing in key discoveries about immunity and immune system function, and building infrastructure, to make that bold idea a reality.

Removing the barrier surrounding solid tumors clears path for T cells

Penn researchers uncover a new way to target solid tumors. Using CAR T cells to remove cancer-associated fibroblasts surrounding pancreatic tumors allows T cells to infiltrate and attack the tumor cells.

A suit of armor for cancer-fighting cells
3d render of T cells attacking cancer cells

Chimeric antigen receptor T cell (CAR T) therapy has delivered promising results, transforming the fight against various forms of cancer, but for many, the therapy comes with severe and potentially lethal side effects. Now, a research team led by Michael Mitchell of the School of Engineering and Applied Science has found a solution that could help CAR T therapies reach their full potential while minimizing severe side effects.
