The binding forces of YT cells to β-1,3-glucan were comparable to previously reported receptor ligands such as LFA-1 and ICAM-138,39, and to H7-B6 (Fig. 3c), the canonical ligand for NKp30 expressed by K562 tumor cells, while there was only minimal binding to mannan or pustulan (Fig. 3a–c). Here, ITGB2 is linked to neoplasm.
