Expression data for tumor-infiltrating CD45+ cells

Project description:Regulatory T (Treg) cells are crucial for immune homeostasis but they also contribute to tumor immune evasion by promoting a suppressive tumor microenvironment (TME). Mice with Treg cell-restricted Neuropilin 1 deficiency show tumor resistance while maintaining peripheral immune homeostasis, thereby providing a controlled system to interrogate the impact of intratumoral Treg cells on the TME. Using this and other genetic models, we showed that Treg cells shaped the transcriptional landscape across multiple tumor-infiltrating immune cell types. Treg cells suppressed CD8+ T cell secretion of interferon- (IFN), which would otherwise block the activation of sterol regulatory element-binding protein 1 (SREBP1)-mediated fatty acid synthesis in immunosuppressive (M2-like) tumor-associated macrophages (TAMs). Thus, Treg cells indirectly but selectively sustained M2-like TAM metabolic fitness, mitochondrial integrity and survival. SREBP1 inhibition augmented the efficacy of immune checkpoint blockade, suggesting that targeting Treg cells or their modulation of lipid metabolism in M2-like TAMs could improve cancer immunotherapy. Microarray gene expression assay was performed to interogate the impact of fragile (Nrp1–/–) Tregs on the gloabal transcriptome oftumor immune infiltrates (CD45+ cells) at various time points over the course of tumor growth.

scRNA seq analysis of CD45+ tumor infiltrating cells (TICs) of B16F10 tumor-bearing Trem1+/+ and Trem1-/- mice.

Project description:To gain a global understanding of the impact of TREM1 silencing, we analyzed the CD45+ tumor infiltrating cells (TICs) of B16F10 tumor-bearing Trem1+/+ and Trem1-/- mice. Utilizing the 10x Genomics Chromium Platform, we analyzed approximately 5390 cells per sample with a coverage rate of 15493 genes per cell.

Transcriptome analysis of tumor infiltrating NK and T cells in CT26-bearing BALB/C mice

Project description:CT26 tumors were implanted subcutaneously into syngeneic BALB/C mice and allowed to grow for 15-25 days. Tumors were collected, mechanically dissociated, and immune cells enriched using Percoll gradient. Cells were then stained with viability dye, CD45, CD3, and NKp46 to FACS sort for T cells (Live/CD45+/CD3+/NKp46-) and NK cells (Live/CD45+/CD3-/NKp46+). Isolated tumor infiltrating NK and T cells were then processed for RNA sequencing analysis.

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.
