Microbial Peptides Activate Tumor-Infiltrating Lymphocytes in Glioblastoma

Project description:Microbial organisms play key roles in numerous physiological processes in the human body and have recently been shown to modify the response to cancer radiotherapy and immune checkpoint inhibitors. Here, we demonstrate that HLA molecules of both glioblastoma tissues as well as tumor cell lines present bacteria-specific peptides. This finding prompted us to examine whether tumor-infiltrating lymphocytes (TILs) recognize intratumoral microbiota. Indeed, bacterial peptides eluted from HLA-DR II molecules are recognized by both TILs, albeit weakly, and peripheral blood-derived memory CD4+ T cells, which, upon stimulation with bacterial peptides, also recognize several tumor antigens. Furthermore, using an unbiased antigen discovery approach for a TIL CD4+ T cell clone (TCC) we show that it recognizes a broad spectrum of peptides from pathogenic bacteria, commensal gut microbiota and also glioblastoma-related tumor antigens. These peptides were strongly stimulatory for bulk TILs and peripheral blood memory cells. Our data hint at how bacterial pathogens and bacterial gut microbiota can be involved in specific immune recognition of tumor antigens.

Autologous Tumor Infiltrating Lymphocytes MDA-TIL in Treating Patients With Recurrent or Refractory Ovarian Cancer, Colorectal Cancer, or Pancreatic Ductal Adenocarcinoma

Project description:This phase II trial studies how well autologous tumor infiltrating lymphocytes MDA-TIL works in treating patients with ovarian cancer, colorectal cancer, or pancreatic ductal adenocarcinoma that has come back (recurrent) or does not respond to treatment (refractory). Autologous tumor infiltrating lymphocytes MDA-TIL, made by collecting and growing specialized white blood cells (called T-cells) from a patient’s tumor, may help to stimulate the immune system in different ways to stop tumor cells from growing.

Adoptive Cell Therapy Using Cancer Specific CD8+ Tumor Infiltrating Lymphocytes in Adult Patients With Solid Tumors

Project description:The subject of this study is the adoptive transfer of selected autologous tumor infiltrating lymphocytes (TIL) after in vitro expansion for the treatment of solid tumor malignancies. The TIL selection process is based on evidence showing that CD8+ TIL which co-express both CD39 and CD103 harbor the bulk of tumor-reactivity and that the remaining CD8 TIL is mainly composed of non-tumor reactive bystander cells. All of the expanded TIL that are produced (1-40 billion are expected) will be delivered in the form of a cell suspension to the participants by intravenous infusion. It is proposed that these selected TIL will produce a more potent and efficacious treatment of late-stage cancer.

CD8+/CD103+ tumor-infiltrating lymphocytes are tumor-specific tissue-resident memory T cells and a prognostic factor for survival in lung cancer patients

Project description:We had previously demonstrated the role of CD103 integrin on lung tumor-infiltrating lymphocyte (TIL) clones in promoting specific TCR-mediated epithelial tumor cell cytotoxicity. However, the contribution of CD103 on intratumoral T-cell distribution and functions, and the prognosis significance of TIL subpopulations in non-small cell lung carcinoma (NSCLC) have thus far not been systematically addressed. Here we investigate the transcriptomic profil of these cell population, using PBMC cells as control.

Non-cancerous liver infiltrating lymphocytes of hepatitis C and tumor-infiltrating lymphocytes

Project description:Study goal is to disclose features of gene expressio profile of non-cancerous liver-infiltrating lymphocytes of type C hepatitis patients with hepatocellular carcinomas and tumor-infiltrating lymphocytes of type C hepatitis patients with hepatocellular carcinomas. Keywords: gene expression profile, non-cancerous liver-infiltrating lymphocytes, tumor-infiltrating lymphocytes, type C hepatitis, hepatocellular carcinoma Non-cancerous liver-infiltrating lymphocytes were obtained by laser capture microdissection from surgically resected liver tissues of 12 type C hepatitis patients with hepatocellular carcinoma. The mRNA was amplified and expression profile was comprehensively analyzed with reference RNA using oligo-DNA chip.
