Journal ArticleDOI
Structural basis for small molecule targeting of the programmed death ligand 1 (PD-L1)
Krzysztof M. Zak,Przemyslaw Grudnik,Katarzyna Guzik,Bartosz J. Zieba,Bogdan Musielak,Alexander Dömling,Grzegorz Dubin,Tad A. Holak,Tad A. Holak +8 more
TL;DR: It is shown that these small-molecule compounds bind directly to PD-L1 and that they potently block PD-1 binding.
Journal ArticleDOI
Structural Biology of the Immune Checkpoint Receptor PD-1 and Its Ligands PD-L1/PD-L2
Krzysztof M. Zak,Przemyslaw Grudnik,Katarzyna Magiera,Alexander Dömling,Grzegorz Dubin,Tad A. Holak,Tad A. Holak +6 more
TL;DR: The latest work on structural characterization of the checkpoint proteins, their interactions with cognate ligands and with therapeutic antibodies reveals that they all have a similar modular structure, composed of small domains similar in topology to the domains found in antibodies.
Journal ArticleDOI
Small-Molecule Inhibitors of the Programmed Cell Death-1/Programmed Death-Ligand 1 (PD-1/PD-L1) Interaction via Transiently Induced Protein States and Dimerization of PD-L1
Katarzyna Guzik,Krzysztof M. Zak,Przemyslaw Grudnik,Katarzyna Magiera,Bogdan Musielak,Ricarda Törner,Lukasz Skalniak,Alexander Dömling,Grzegorz Dubin,Tad A. Holak +9 more
TL;DR: NMR and X-ray characterization is presented for the two classes of small-molecule PD-1/PD-L1 inhibitors that carry a number of disadvantages such as the high cost of the antibodies, their limited half-life, and immunogenicity.
Journal ArticleDOI
Small-molecule inhibitors of PD-1/PD-L1 immune checkpoint alleviate the PD-L1-induced exhaustion of T-cells
Lukasz Skalniak,Krzysztof M. Zak,Katarzyna Guzik,Katarzyna Magiera,Bogdan Musielak,Magdalena Pachota,Bozena Szelazek,Justyna Kocik,Przemyslaw Grudnik,Marcin Tomala,Sylwia Krzanik,Krzysztof Pyrc,Alexander Dömling,Grzegorz Dubin,Tad A. Holak +14 more
TL;DR: Evidence is provided that small molecules are capable of alleviating the PD-1/PD-L1 immune checkpoint-mediated exhaustion of Jurkat T-lymphocytes and the X-ray structures of the complexes of B MS-1001 and BMS-1166 were determined, which revealed features that may be responsible for increased potency of the compounds compared to their predecessors.
Journal ArticleDOI
Protein targeting by the signal recognition particle
TL;DR: This work presents an updated perception of the order of events in SRP-mediated protein targeting, in which the activation of GTP hydrolysis plays a key role for membrane insertion of substrate proteins.
