ITGB2 and breast carcinoma: The characterization of other canonical adhesion molecules expressed by this breast cancer line revealed high expression levels of β1 integrins and low expression levels of the low affinity LFA-1 ligand ICAM-2 with a negligible expression of β2 integrins and P-selectin ligand implicated in cancer–cell platelet interactions (42) (Supplementary Figure 3).
