Study reveals how to activate the immune system’s natural killer cells to protect against cancer and other diseases

Collagens and elastin in the extracellular matrix, which forms a scaffold to support organs, cause the immune system's natural killer cells to switch off their 'killer' function. The hypertension drug losartan can cause a previously resistant melanoma to become sensitive to natural killer cells by blocking collagen deposition in the tumor.
