APOA1 and neoplasm: Additionally, specific lipid-related ligands, including apolipoprotein A1 (Apo-A1) and ATP synthase/F1-ATPase (recognized as a high-affinity apo A-I receptor), have been identified as ligands for the Vɣ9Vδ2 TCR on tumor cells, suggesting a potential role for γδ T cells in recognizing lipid molecules (106).
