Target cell surface antigen

"Target cell surface antigen" is a generic term denoting any protein, glycoprotein, or glycolipid expressed on the surface of cells that can serve as a binding site for immune system recognition or drug targeting. Cell surface antigens are critical in immunophenotyping, targeted therapy, and diagnostics. As a class, they represent diverse molecules serving as disease markers or therapeutic targets, but the term alone lacks the specificity required to define a single drug target[1][3][4][5]. This entry should be replaced with the precise name of a specific cell surface protein, such as "Cluster of differentiation 19 (CD19)" or "Epidermal growth factor receptor (EGFR)" to enable meaningful annotation, drug matching, and mechanism-of-action assignment.
