T cells that carry CARs are already used to treat people with blood cancers. These receptors tell immune cells, such as T cells, to attack cancers. However, cancer cells often find ways to ‘hide’ from our immune system.Ĭhimeric antigen receptors, or CARs, are receptors designed in a laboratory to attach to specific proteins that are found on a cancer cell.

It can spot these threats because it recognizes certain signals at the surface of dangerous cells. Our immune system constantly patrols our body, looking to eliminate cancerous cells and harmful microbes. Finally, we show that CAR-P expressing murine macrophages reduce cancer cell number in co-culture by over 40%. Addition of a tandem PI3K recruitment domain increased cancer cell engulfment.

We show that CAR-Ps drive specific engulfment of antigen-coated synthetic particles and whole human cancer cells. By screening a panel of engulfment receptor intracellular domains, we found that the cytosolic domains from Megf10 and FcRɣ robustly triggered engulfment independently of their native extracellular domain. CAR-Ps consist of an extracellular antibody fragment, which can be modified to direct CAR-P activity towards specific antigens. Here, we engineered a family of Chimeric Antigen Receptors for Phagocytosis (CAR-Ps) that direct macrophages to engulf specific targets, including cancer cells. The success of CAR-T cell therapies highlights the promise of programmed immunity and suggests that applying CAR strategies to other immune cell lineages may be beneficial.

Chimeric antigen receptors (CARs) are synthetic receptors that reprogram T cells to kill cancer.
