Responders to immune checkpoint therapy display early clonal expansion of tumour-infiltrating lymphocytes

Project description:Using murine models that exclude variation in host genetics, environmental factors and tumour mutation burden, limiting variation between animals to naturally diverse TCRβ repertoires, we applied bulk TCRseq to study TCRβ repertoire dynamics in ICT responders and non-responders

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.

Tumour infiltrating leukocytes

Project description:Murine tumour infiltrating lymphocytes (CD8+ T cells) were index-sorted based on expression of CD8a and CD3e. Subsequently cDNA was generated from these samples using the Smart-seq2 protocol. This data is part of a pre-publication release.

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.

RNA-seq analysis of CD8 tumour infiltrating lymphocytes from GFP-Egr2 Knockin and hCD2-Cre Egr2loxP/loxP Egr3-/- mice

Project description:To determine the effect of Egr2 and Egr3 on tumour infiltrating lymphocyte gene expression, GFP-Egr2 knockin (Egr2 Kin) and hCD2-Cre Egr2loxP/loxP Egr3-/- (Egr2/3 DKO) mice were inoculated with MC38 or B16 tumour cells. Fourteen days later, GFP-Egr2high and Egr2-/-Egr3-/- CD8+ tumour infiltrating lymphocytes were isolated from Egr2 Kin and Egr2/3 DKO mice, respectively, and analysed by RNA-seq.

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.

Tumor Infiltrating Lymphocytes and Immune-Related Genes as Predictors of Outcome in Pancreatic Adenocarcinoma

Project description:Background. We investigated the correlation of pancreatic ductal adenocarcinoma patient prognosis with the presence of tumor infiltrating lymphocytes and expression of 521 immune system genes. Methods. Intratumoral CD3+, CD8+, and CD20+ lymphocytes were examined by immunohistochemistry in 12 PDAC patients with different outcomes who underwent pancreaticoduodenectomy. The results were correlated with the gene expression profile using the digital multiplexed NanoString nCounter analysis system (NanoString Technologies, Seattle, WA, USA). Results. Twenty immune system genes were significantly differentially expressed in patients with a good prognosis relative to patients with a worse prognosis: TLR2 and TLR7 (Toll-like receptor superfamily); CD4, CD37, FOXP3, PTPRC (B cell and T cell signalling); IRF5, IRF8, STAT1, TFE3 (transcription factors); ANP32B, CCND3 (cell cycle); BTK (B cell development); TNF, TNFRF1A (TNF superfamily); HCK (leukocyte function); C1QA (complement system); BAX, PNMA1 (apoptosis); IKBKE (NFB pathway). Differential expression was more than twice log 2 for TLR7, TNF, C1QA, FOXP3, and CD37. Discussion. Tumor infiltrating lymphocytes were present at higher levels in samples from patients with better prognosis. Our findings indicate that tumor infiltrating lymphocyte levels and expression level of the genes listed above influence pancreatic ductal adenocarcinoma prognosis. This information could be used to improve selection of best responders to immune inhibitors.
