Chimeric efferocytic receptors improve apoptotic cell clearance and alleviate inflammation

摘要

Our bodies turn over billions of cells daily via apoptosis and are in turn cleared by phagocytes via the process of"efferocytosis."Defects in efferocytosis are now linked to various inflammatory diseases.Here,we designed a strategy to boost efferocytosis,denoted"chimeric receptor for efferocytosis"(CHEF).We fused a specific signaling domain within the cytoplasmic adapter protein ELMO1 to the extracellular phosphatidylserine recognition domains of the efferocytic receptors BAI1 or TIM4,generating BELMO and TELMO,respectively.
