About CERo Therapeutics

CERo Therapeutics, Inc. is developing cell-based therapies that incorporate multiple forms of tumor clearance into single cells. The company’s CER-T platform lies at the intersection of innate and adaptive cell clearance, combining the body’s natural signaling mechanisms, which are capable of recognizing and disposing of unwanted cells, with traditional T cell killing. The integrated approach draws on recent advances in molecular immunology and insights related to the downstream signaling of specialized receptors that cooperate to eliminate dangerous cells and pathogens.
