Monoamine oxidase A (MAO-A) is an outer mitochondrial membrane-bound enzyme best known for its function in the brain, but also linked to cancer progression. Here, the authors show that MAO-A is expressed in tumor associated macrophages, promoting their immunosuppressive properties, and that MAO inhibition suppresses tumor growth in preclinical models.
