Outline of Final Research Achievements

Linear polyubiquitin chains are generated specifically by the ubiquitin ligase complex LUBAC. LUBAC is composed of one catalytic subunit, HOIP and two accessary subunits, HOIL-1L and SHARPIN. In this study I analyzed the role of LUBAC in TLR4-mediated cell death of B cells lacking LUBAC activity. I found that among two signal transduces downstream of TLR4, MyD88 and TRIF TRIF is responsible for this cell death because ablation of TRIF prevented TLR4-induced cell death of HOIP deficient B cells. I also discovered that deletion of RIP3, a critical regulator of necroptosis alone did not inhibit TLR4-induced cell death but the inhibition of Caspase-8 together with RIP3 deletion restored LPS-induced survival and cell proliferation of HOIP deficient B cells. These data show that LUBAC plays critical roles in the inhibition of Caspase-mediated apoptosis induced by TLR4 stimulation.
