Using target-agnostic, high-content, image-based identification of indicative phenotypic changes induced by small molecules, the Waldmann lab identified autogramins as a new class of autophagy inhibitor. Autogramins selectively target the recently discovered cholesterol transfer protein GRAMD1A.
In this context the group could identify a new role of cholesterol in autophagy and a new biological function of recently discovered cholesterol transfer protein GRAMDA1.
