Isoginkgetin derivative IP2 enhances the adaptive immune response against tumor antigens
Abstract
Darrigrand, Pierson et al. study the effect of mRNA splicing inhibitors on the generation of the MHC class I ligands. They developed a derivative of the spliceosome inhibitor isoginkgetin which is less toxic and more effective at enhancing antigen presentation and CD8+ T cell activation and showed greater antitumour activity in vivo. These findings identify the spliceosome as a druggable target for the development of epitope-based immunotherapies.
