Stress-induced NKG2D ligands (MICA, MICB, ULBP1-6) (NKG2D ligands (NKG2DL))

Stress-induced NKG2D ligands are surface proteins belonging to the MICA/B and ULBP families whose expression is upregulated in response to cellular stress, such as DNA damage, oxidative stress, or oncogenic signals. These ligands are recognized by the NKG2D receptor expressed on natural killer cells, cytotoxic T cells, and certain other immune populations, triggering immune-mediated lysis of stressed or transformed cells[1][2][3][4][6]. Cancer cells frequently modulate the expression, maturation, and shedding of these ligands to evade immune detection, making NKG2D ligand pathways central to both immune surveillance and tumor immune escape. Therapeutic interventions are being developed to exploit ligand expression for targeted immunotherapy and to prevent tumor-mediated suppression of the immune response[1][2][3][6].
