Cells

The term **"cells"** is not a valid or specific therapeutic target in the context of drug discovery or molecular pharmacology. In biomedical research and drug development, a "target" typically refers to a specific molecule—most often a protein (such as an enzyme, receptor, ion channel, or transporter) or nucleic acid—that can be modulated by drugs to achieve a therapeutic effect[2]. "Cells" is too broad and non-specific; it refers to the basic structural and functional units of living organisms rather than any particular molecular entity that could serve as a direct target for drugs. Therefore, "cells" does not meet the criteria for being considered a canonical drug target and should be replaced with the name of an actual molecule (e.g., "Epidermal growth factor receptor") if structured information about targets is required[2].
