Still, gene expression data indicated that the tumor microenvironment affects the gene expression found upon tumor tissue dissection, also when the same glioblastoma cell line was used. Further exploration of the tumor microenvironment in the intracranial versus subcutaneous setting could be developed with...

Last but not least, immunosuppressive mechanisms in the tumor microenvironment (TME) other than the PD-L1/PD-1 and CTLA-4 pathways may render checkpoint blockade ineffective, such as inhibitory myeloid cell types and CD4+ T-regulatory cells6,7,8. In order to build on the first promising ...
(E) Distribution of overall expression scores (y axis) of the decoupled pan-cancer dysfunction program (minus immune checkpoints: PDCD1, TIGIT, HAVCR2, LAG3, and CTLA4) in CD8+ T cells stratified as in (D). Middle line: median; box edges: 25th and 75th percentiles, whiskers: most extr...
DOX also inhibited tumor growth and enhanced the antitumor activity of PD-1 inhibitors in C57BL6 and BALB/c mice subcutaneously inoculated with B16-F10 and 4T1 cells, respectively. In conclusion, the combination of DOX and PD-1 inhibitor could be an anticancer strategy. Graphical abstract ...
Importantly, treatment with Compound-182 rendered otherwise resistant tumors sensitive to α-PD-1 therapy. Our findings establish the potential for small molecule inhibitors of PTP1B and PTPN2 to enhance anti-tumor immunity and combat cancer.
Anti-TIGIT antibody improves PD-L1 blockade through myeloid and Tregcells ArticleOpen access28 February 2024 Introduction Immunotherapy targeting the T cell inhibitory receptor programmed death-1 (PD-1) and its ligand PD-L1 holds promise in lung cancer treatment1. However, given the limited therapeut...
immunity and the response to PD-1 checkpoint blockade6,10. These preclinical findings appear to be relevant to human tumors, since low PTPN2 protein in triple-negative breast cancer (TNBC) is accompanied with TILs/T cells and increased PD-L1 levels, whereas lowPTPN2mRNA is associated with ...
279, a pharmacological agent initially developed for Ewing sarcoma15, can reverse FLI1-mediated suppression of T cell immunity. Furthermore, it synergistically augments the effects of anti-PD-1 therapy in suppressing tumor growth, thereby introducing a potential therapeutic strategy for NPC....
PD-L1 or secreted molecules such as TGFβ or IL-10, ultimately suppressing T and NK cell activity [12,13]. In breast cancers, MDSC populations are expanded through increased signaling by cytokines and chemokines such as IL-6, G-CSF and CCL2 [14,15,16]. Importantly, IL-1β is a ...
