Immunotherapies, such as checkpoint inhibitor drugs, have made worlds of difference for the treatment of cancer. Most clinicians and scientists understand these drugs to act on what’s known as the adaptive immune system, the T cells and B cells that respond to specific threats to the body.
New research from an international team co-led by George Hajishengallis of the University of Pennsylvania School of Dental Medicine suggests that the innate immune system, which responds more generally to bodily invaders, may be an important yet overlooked component of immunotherapy’s success.
Their work, published in the journal Cell, found that “training” the innate immune system with β-glucan, a compound derived from fungus, inspired the production of innate immune cells, specifically neutrophils, that were primed to prevent or attack tumors in an animal model.
