Multiple immune and endothelial cell types

The term Multiple immune and endothelial cell types does not refer to a specific molecular target, such as a protein, receptor, or enzyme. In the context of drug discovery and pharmacology, a therapeutic target is defined as a discrete biological entity—most commonly a protein—that can be specifically modulated by a drug to achieve a therapeutic outcome (IUPHAR/BPS Guide to Pharmacology, 2023). This entry instead describes a broad physiological environment or a collection of cell populations, including various leukocytes (immune cells) and the cells lining the vascular system (endothelial cells). While these cells express numerous valid therapeutic targets, the collective grouping of cell types is not itself a target. This designation is likely a descriptive error or a placeholder in a database intended to indicate the tissue distribution or the pleiotropic effects of a therapeutic agent across different cellular compartments.
