We previously identified two glioma-derived αvβ3/αvβ5-integrin receptors ligands, osteopontin/secreted phosphoprotein 1 (SPP1) and lactadherin/milk fat globule-epidermal growth factor 8 (MFG-E8), as activators of myeloid cell reprogramming in gliomas [21]. The gene discussed is SPP1; the disease is glioma.
