CTLA4

[Nature Cell Biology] Investigators report that PD-L1 translocated from the plasma membrane into the nucleus through interactions with components of the endocytosis and nucleocytoplasmic transport pathways, regulated by p300-mediated acetylation and HDAC2-dependent deacetylation of PD-L1.

[Proceedings of the National Academy of Sciences of the United States of America] Researchers found that their engineered nanoparticles carrying a CpG DNA ligand of TLR9 could suppress tumor growth in several animal models of various cancers, resulting in an abscopal effect on distant tumors, and improving responsiveness to anti-CTLA4 treatment with combinatorial effects after intratumoral administration.
