Furthermore, hepatic Thy1+ NK cells have been shown to play an important role in viral clearance, antibacterial immunity, and cytotoxicity toward tumor cells, albeit this is a low-density marker.75, 76, 77 As such, α-Thy1.2 may inhibit activated NK cells bearing the Thy1 marker, and the reduction in survival of the vanadyl sulfate plus NDV treatment group when α-Thy1.2 was used to deplete T cells may be attributed to a reduction in NK cell numbers. The gene discussed is THY1; the disease is neoplasm.
