Human cancer cell surface

The human cancer cell surface is the external boundary of a malignant cell, comprising a lipid bilayer enriched with a diverse array of proteins, carbohydrates, and lipids collectively known as the surfaceome. This interface is critical for oncogenesis, as it mediates essential processes such as signal transduction, nutrient acquisition, and evasion of the host immune system (Nature Reviews Cancer, 2018). While the surface contains numerous specific, high-value therapeutic targets—including receptor tyrosine kinases like EGFR and HER2, and checkpoint proteins like PD-L1—the term itself describes a biological compartment rather than a single druggable entity (NCI Dictionary). Therapeutic strategies targeting the cancer cell surface often utilize monoclonal antibodies, antibody-drug conjugates, or CAR-T cells designed to recognize specific overexpressed or mutated antigens (PubMed, 2021). However, the significant heterogeneity of surface marker expression between different patients and even within the same tumor presents a major challenge for the development of universal surface-targeted therapies (NIH, 2023).
