Project description:Tumor-infiltrating myeloid cells (TIMs) have emerged as key regulators in tumor progression, however, the similarity and discrepancy of the fundamental properties of these cells across different cancer types remain elusive. Here, we performed a pan-cancer analysis of TIM sub-populations in multiple human cancer types. Our comprehensive analyses provide valuable insights for understanding the TIM properties across multiple tumors.
Project description:T cells present diverse states in the tumor, playing a central role in cancer immunity and immunotherapies. However, their heterogeneity, dynamics and composition within tumors of various cancer types are not fully characterized. Integrating a pan-cancer single-cell RNA sequencing atlas of T cells cross multiple cancer types, we systematically characterized their diversity, identified the potentially tumor-reactive T cells, and revealed new cell types. Our findings provide new insights into T cell immunity and will facilitate immunotherapy development targeting T cells in human cancer.
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.
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.

Project description:The tumor immune cell composition dictates cancer outcomes. To capture this tumor immune cell diversity, we isolated tumor infiltrating leukocytes from tamoxifen induced tumors of Tyr::CreER;BRAFCAPTENloxp mice for single cell RNA sequencing
Project description:Goblet cells are considered as a homogeneous population in total tumor-infiltrating CD8+ T cells. We used single cell RNA sequencing (scRNA-seq) to analyze the diversity of total tumor-infiltrating CD8+ T cells.
Project description:Systematic interrogation of tumor-infiltrating lymphocytes is key to the development of immunotherapies and the prediction of their clinical responses in cancers. Here, we perform deep single-cell RNA sequencing on single T cells isolated from peripheral blood, tumor and adjacent normal tissues from hepatocellular carcinoma patients.
