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.

Evaluation of Tumor Infiltrating Lymphocytes in High-Grade Serous Ovarian Cancer

Project description:Tumor infiltrating lymphocytes (TILs) play a significant role in the tumor microenvironment in high-grade serous ovarian cancer (HGSOC). To better understand the interactions and functions of TILs in HGSOC progression, we performed proteogenomic profiling of TILs in 65 tumors collected from 12 HGSOC patients.

Single-cell RNA-seq of tumor-infiltrating lymphocytes in metastatic uveal melanoma

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.

CD8+ T cells in peripheral blood lymphocytes and tumor-infiltrating lymphocytes of melanoma patients

Project description:CD8+ T cells are the primary target of immune checkpoint inhibitor (ICI) therapy in the treatment of melanoma. ICI therapy only benefits a subset of patients and complicating this issue is a reliable prediction method that does not require invasive biopsies. In the hope of remedying this challenge, we conducted single-cell transcriptomic analyses of CD8+ T cells in peripheral blood lymphocytes (CD8-mPBLs) and, importantly, tumor-infiltrating lymphocytes (CD8-mTILs) from 8 patients with metastatic melanoma.

RNA Profiling in Patients' tumor infiltrating lymphocytes

Project description:Identifying tumor antigen-specific T cells from cancer patients has been a goal of tumor immunologists for several decades. Co-expression of CD103 and CD39 on CD8 TIL highly enriches for tumor-reactive T cells. CD39+CD103+ CD8 TIL have a distinct TCR repertoire compared to other CD8 TIL subsets and are clonally expanded within the tumor. They are highly enriched for tumor antigen recognition and efficiently killed autologous tumor cells. Patients with head and neck cancer whose CD8 TIL contained a higher frequency of CD39+CD103+ cells experienced a greater overall survival. This work describes a simple and effective method for detecting tumor-reactive CD8 TIL.

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.
