Receptor-interacting protein kinase 1 is a key mediator in TLR3 ligand and Smac mimetic-induced cell death and suppresses TLR3 ligand-promoted invasion in cholangiocarcinoma

      Cholangiocarcinoma (CCA) is a cancer of the bile duct with no effective therapy. This study explores the potential of inducing ‘apoptosis’ and ‘necroptosis’, a form of cell death, as a new effective therapeutic strategy for the treatment of CCA patients. Here, the combination treatment with a Toll-like receptor 3 (TLR-3) ligand, and a smac mimetic, synergistically induced CCA cell death by apoptosis and necroptosis, and this killing is dependent on Receptor-interacting protein kinase 1 (RIPK1). Therefore, therapeutic targeting TLR3 by TLR3 ligands in combination with Smac mimetic could bring a new, effective therapeutic concept for the treatment of CCA patients.
