BTNL9 and neoplasm: Further study of the engagement of the Vγ9Vδ2 TCR, possibly with BTN3 targets, is likely to carry significant implications for γδT cell anti-tumor immunity by supporting the notion that stress recognition, particularly in combination with Ab-opsonisation, may be sufficient not only for killing of a tumor cell but also for uptake, processing and presentation of tumor-associated antigens23.
