Proteasome regulator PSME4 reduces cellular inflammation and promotes an immunosuppressive tumor microenvironment

ABSTRACT: We observed that proteasome regulator PSME4 inhibits antigen presentation and reduces cellular inflammation in lung adenocarcinoma. As tumor inflammation and antigenicity are key to anti-tumor immunity, we examined the effect of PSME4 in vivo by injecting mice with either KP1.9 or KP1.9PSME4_KD lung adenocarcinoma. We analyzed the changes in the immune milieu by performing single cell RNA sequencing (sc-RNA seq) of CD45+ cells, 3 weeks following injection of tumor cells. This allowed us to examine the effect of PSME4 on the early immune response to the tumor.

Early human lung immune cell development and its role in epithelial cell fate

Project description:In this work, we collected CD45-enriched human lung cells from 6 to 22 week post conception (pcw) and built a single-cell transcriptomic and proteomic cell atlas.. At the embryonic stage, we observed an early wave of innate immune cells, including ILCs, NK, myeloid cells and lineage progenitors. By the canalicular stage, we detected naive T lymphocytes high in cytotoxicity genes, and mature B lymphocytes, including B1 cells. Our analysis suggests that fetal lungs provide a niche for full B cell maturation. Given the abundance of immune cells, we investigated their possible effect on epithelial maturation and found that IL-1β drives epithelial progenitor exit from self-renewal and differentiation to basal cells in vitro. In vivo, IL-1β-producing myeloid cells were found adjacent to epithelial tips, suggesting that immune cells may direct the developing lung epithelium.

The effect of insulin-like growth factor 1 treatment on cardiac myeloid cells 3 days post-myocardial infarction

Project description:To test the mechanism by which IGF1 is cardioprotective, we performed single cell RNA sequencing on myeloid cells isolated from the heart 3 days after myocardial infarction of mice with and without IGF1 treatment. Myocardial infarction was induced in C57Bl6/J mice by 45 min occlusion of the left anterior descending artery followed by 3 days of reperfusion. Animals of the IGF1 group (n=3) received 40 ng/g mature recombinant IGF1 subcutaneously as bolus at the beginning of reperfusion. In addition, IGF1 (1 µg/g/d) was administered continuously during reperfusion using micro-osmotic pumps (Alzet, 1003D) that were implanted subcutaneously. Control mice received vehicle (0.1% BSA). After 3 days hearts were digested and CD45+CD11b+ cells were isolated using FACS cell sorting. Each sample contained cells containing 1 control and 1 IGF1 treated mouse, labeled with TotalSeq hashtags. 16000 cells were used as input for the single-cell droplet libraries generation for each sample.

scRNAseq of immune cells of patients with chronic graft-versus-host disease

Project description:In this study, we investigated somatic mutations in T cells in patients with various hematological disorders. To analyze immune cell phenotypes with somatic mutations, we performed scRNA+TCRab sequencing from 9 patients with chronic GVHD and clonal expansions of CD4+ or CD8+ T cells based on T cell receptor sequencing. CD45+ PBMCs (lymphocytes and monocytes) were sorted with BD Influx cell sorter and subjected to sequencing with Chromium VDJ and Gene Expression platform (v1.1, 10X Genomics). Sequencing was performed with Novaseq 6000 (Illumina). The immune cell phenotypes were compared to healthy controls processed in the same laboratory (accession number E-MTAB-11170). Due to data privacy concerns, the raw sequencing data is in the European Genome-Phenome Archive (EGA) under accession code [xxxx] and can be requested through the EGA Data Access Committee.

Hepatocyte-controlled availability of activated TGFb reprograms macrophage polarization affecting liver injury and regeneration

Project description:We describe a distinct macrophage population, whose presence in the liver during homoeostasis depends on recruitment signals mediated by the chemokine receptor CCR2. The identified polarization state of this population closely resembles that induced in co-culture experiments, where hepatocytes are reducing the availability of TGFb to macrophages. Accordingly, disruption of TGFb signal transduction in macrophages phenocopies the influence of hepatocytes on macrophage polarization.

Single cell RNA-seq of pancreatic mouse tumors upon treatment

Project description:KRAS-mutant pancreatic ductal adenocarcinoma (PDAC) is highly immunosuppressive and resistant to targeted therapies, immune checkpoint blockade and engineered T cells. In this study, we performed a systematic high throughput combinatorial drug screen and identified a synergistic interaction between the MEK inhibitor trametinib and the multi- kinase inhibitor nintedanib. Using single cell RNA sequencing and immunophenotyping, we show that the combination therapy reprograms the immunosuppressive microenvironment and primes cytotoxic and memory T cells to infiltrate the tumors, thereby sensitizing mesenchymal PDAC to PD-L1 inhibition.
