If a drug inhibits clathrin-mediated endocytosis at the cell membrane, which consequence follows?

💡 Explanation

Inhibition of clathrin-mediated endocytosis prevents the internalization of receptors from the cell membrane, thereby blocking receptor downregulation, because clathrin is essential for vesicle formation. Therefore, the receptor remains on the cell surface, rather than being internalized and degraded, as occurs in typical receptor downregulation.
