Tumor cell membrane antigens recognized by NK cell activating receptors

The phrase "Tumor cell membrane antigens recognized by NK cell activating receptors" does not correspond to a single molecule or protein but rather to a diverse set of surface-expressed ligands on tumor cells, such as MICA, MICB, ULBPs, and B7-H6, which are specifically recognized by natural killer (NK) cell activating receptors including NKG2D, NKp30, NKp44, and NKp46[2][3][5][7]. These ligands are typically upregulated in response to cellular stress, infection, or malignant transformation, allowing NK cells to detect and destroy tumor cells. Therapeutically, this axis is important in immuno-oncology for developing drugs and engineered cell therapies aimed at boosting immune surveillance, but its heterogeneity, redundancy, and the risk of tumor evasion limit its precision as a singular target. Therefore, the query represents a functional category or target class, not a distinct, canonical molecular entity, and is considered non-specific for structured target listings.
