STING protein activates a pathway that kills tumor-fighting immune cells

The immune protein STING has long been noted for helping protect against viruses and tumors by signaling a well-known immune molecule. Now, UT Southwestern scientists have revealed that STING also activates a separate pathway, one that directly kills tumor-fighting immune cells.

Eliminating tumors with engineered ‘off-the-shelf’ therapeutic T cells

Personalized cancer treatments are no longer just options of the future. In the past few years, researchers have made significant progress in 'teaching' the body's immune T cells to recognize and kill specific cancer cells, and human clinical trials have shown that this approach can successfully eliminate tumors
