Current antiangiogenic immunotherapeutic strategies mainly focus on the blockade of circulating cytokines or receptors that are overexpressed by endothelial cells. We proposed globotriaosylceramide (Gb3) as a viable alternative target for antiangiogenic therapies. In this setting, we developed an anti-Gb3 antibody and validated its therapeutic efficacy in metastatic tumor models.
Keywords: Gb3; antiangiogenic therapy; antibody; glycosphingolipid.
