BSG and cancer: T adhesion to extracellular matrix glycoproteins, chemotactic migration, homing, extravasation into solid organs, gene expression, cytokine secretion, expression of key proteins (e.g. CD3zeta, CD147 metalloproteinase inducer, laminin receptor and others), proliferative response to cancer, killing of cancer, ability to recruit other immune cells to the site of disease or injury, and most probably additional advantageous effects not revealed yet.
