Disease-localizing surface marker

Disease-localizing surface marker is not a canonical molecule or receptor name but describes a class of markers—typically cell surface proteins—that are differentially expressed on diseased versus non-diseased cells and can be used for purposes such as targeted drug delivery, imaging, or cell-type identification. The specific identity of such markers depends on the disease and the particular cell type, and a large body of research focuses on systematically identifying and ranking candidate molecules for these applications using proteomics and transcriptomics approaches[1][2][3]. Without further specification, this is not a valid molecular target name but rather a research concept.
