UCLA scientists discover way to amp up power of killer T cells - EurekAlert (article link)

(University of California - Los Angeles Health Sciences) Researchers with UCLA's Jonsson Comprehensive Cancer Center have discovered a way to amp up the power of killer T-cells, called CD8 cells, making them more functional for longer periods of time and boosting their ability to multiply and expand within the body to fight melanoma, a new study has found.

"The study, done in mouse models of metastatic melanoma that had spread to the brain, has important clinical implications, as the method could boost the cancer-killing power of experimental immunotherapies being tested now in various cancers, including deadly glioblastoma and metastatic melanoma, both of which are very difficult to treat successfully."

"The process Prins and his team used sought to mimic the way the T cells in the immune system recognize and fight viruses in the body, stimulating what is called the innate immune system. The innate immune system is comprised of cells that immediately defend the body from infection and frequently is not stimulated in the presence of cancer, Prins said. However, the innate immune cells can be tricked into thinking a virus is present by treating with compounds that activate Toll-like receptors (TLR)."
