What is it about?
Using cell lines derived from different anatomical sites they show that those from lymph node metastases express ligands for DNAM-1 (DNAM-1L), mainly CD155, and for NCRs, but low levels of ligands for NKG2D (NKG2DL).

Why is it important?
Simultaneous engagement of several activating receptors contributes to efficient NK cell-mediated lysis of melanoma cells. Moreover, DNAM-1 and NKG2D crosslinking may also contribute to T cell activation.
