St. Jude Children’s Research Hospital scientists have discovered how tumors disable immune “gatekeeper” cells that alert the rest of the immune system to the presence of cancer—and how restoring their energy production can improve immunotherapy. Dendritic cells activate the cytotoxic immune cells that destroy cancer. The researchers found that tumors reduce dendritic cell function by decreasing their mitochondrial fitness, thus preventing formation of the anticancer immune response.
