Project description:For the subcutaneous model, 5x105 KPC-Luc cells were injected subcutaneously near the right flank of female C57BL/6 mice. 6-7 days after tumor implantation mice were randomized into 4 treatment groups and treatedwith VIP-R antagonist and/or anti-PD-1. While scram+IgG control mice received scrambled peptide and isotype IgG, the VIP-R antagonist, anti-PD-1 and VIP-R antagonist and anti-PD-1 groups received VIP-R antagonist and IgG; scrambled peptide and anti-PD-1; and VIP-R antagonist and anti-PD-1, respectively. The treatment regimen involved administering 10μg of scrambled or VIP-R antagonist: ANT008, subcutaneously every day and 200μg of IgG or anti-PD-1 intraperitoneally once every three days, for a total of 10 days.
Project description:For the subcutaneous model, 5x105 KPC-Luc cells were injected subcutaneously near the right flank of female C57BL/6 mice. For the MT5 or Panc02 models, 5x105 were injected subcutaneously near the right flank of female C57BL/6 mice. For the orthotopic KPC-Luc model, mice were anesthetized, and the KPC-Luc cells were suspended in Matrigel and injected in the tail of the pancreas following laparotomy. 6-7 days after tumor implantation mice were randomized into 4 treatment groups and treatedwith VIP-R antagonist and/or anti-PD-1. While scram+IgG control mice received scrambled peptide and isotype IgG, the VIP-R antagonist, anti-PD-1 and VIP-R antagonist and anti-PD-1 groups received VIP-R antagonist and IgG; scrambled peptide and anti-PD-1; and VIP-R antagonist and anti-PD-1, respectively. The treatment regimen involved administering 10μg of scrambled or VIP-R antagonist: ANT008 or ANT308, subcutaneously every day and 200μg of IgG or anti-PD-1 intraperitoneally once every three days, for a total of 10 days.
Project description:Non-inflamed (cold) tumors such as leiomyosarcoma (LMS) do not benefit from immune checkpoint blockade (ICB) monotherapy. Combining ICB with angiogenesis-, or poly-ADP ribose polymerase (PARP) inhibitors may increase tumor immunogenicity by altering the immune cell composition of the tumor microenvironment (TME). The DAPPER phase II study evaluated the safety, immunologic, and clinical activity of ICB-based combinations in pre-treated LMS patients.
Project description:Goal: determine how transcriptome of immune cells within the tumor microenvironment changes as a function of CD40 agonist and/or immune checkpoint blockade (anti-PD-1 AND anti-CTLA-4; "ICB") therapy
Project description:Local administration of IFN-α-producing proliferating myeloid cells (IFN-α-iPSC-pMCs) inhibited the tumor growth not only at the treatment site but also at the distant site (left). T cell receptor (TCR)-β chain repertoire and complementarity determining region 3 (CDR3) gene sequence analyses of tumor-infiltrating lymphocytes (TILs) showed marked enrichment of T cells with identical TCR-β chains in bilateral tumor tissues.
Project description:Single-cell RNA-sequencing and single-cell TCR-sequencing was used to characterize PGE2-mediated changes in the gene expression profile of tumor-infiltrating CD8+ T cells.
Project description:Metastatic uveal melanoma generally responds poorly to immunotherapy. The aim here was to sequence tumor-infiltrating lymphocytes from uveal melanoma metastases to study their phenotypes and T-cell receptor (TCR) clonotypes. We performed paired single-cell transcriptome and TCR sequencing using the 10x Genomics platform of IL2-expanded tumor-infiltrating lymphocytes from 7 liver and 1 subcutaneous metastasis.
