Single cell RNA sequencing of paired non small cell lung carcinoma tissue and peripheral blood from 5 donors

ABSTRACT: The immunosuppressive tumour microenvironment constitutes a significant hurdle to immune checkpoint inhibitors response. Both soluble factors and specialised immune cells such as regulatory T cells (TReg) are key components of active intratumoural immunosuppression. Previous studies have shown that Inducible Co-Stimulatory receptor (ICOS) can be highly expressed in the tumour microenvironment, especially on immunosuppressive TReg, suggesting that it represents a relevant target for preferential depletion of these cells. Here, we performed immune profiling of samples from paired tumour and peripheral blood of 5 patients with non-small cell lung cancer (NSCLC). We found Icos mRNA expression in NSCLC samples was higher in TRegs than in other T cell subsets and higher in the TME than in the periphery with the expression pattern in both compartments following the general trend of: TReg > CD4non-TReg > CD8 > Other.

The role of distinct synovial tissue macrophage populations in shaping synovial tissue microenvironment

Project description:We tested the role of distinct STM populations in the modulation of synovial tissue environment in ex vivo STM-FLS micro co-cultures. We first FACS-sorted total synovial tissue fibroblasts as we described previously from biopsies of RA patients. FLS were seeded at 3000/well alone or in contact with either 3000/well FACS-sorted MerTK/CD206neg or MerTK/CD206pos STMs from patients with active or remission RA respectively for 48h. The modulatory effect on the FLS was evaluated by comparing their expression of 446 immune/stromal genes (scRNAseq BD Rhapsody) 32,141 FLS were evaluated. FLS cells cultured alone exhibited 4 distinct activation states: FLS cluster 1 (FLS1) expressed extracellular matrix proteins (e.g. COL1A1, COL1A2) and TGFb (TGFBI, TGFB3); FLS2 expressed cell adhesion molecules (e.g. ITGB2, SELPLG); FLS3 expressed receptors for TGFb and resolvin (e.g.CMKLR1 and TGFBR1); and FLS4 expressed high levels of glycolytic enzymes and proliferation markers (e.g. LDHA, PGK1, ENO1 and PCNA). Interestingly, upon co-culture with MerTK/CD206neg an additional fifth cluster (FLS5) emerged with inflammatory properties In contrast to inflammatory effect of the MerTK/CD206neg STMs on FLS, the MerTK/CD206pos population, especially that isolated from biopsies of RA patients in sustained disease remission, induced repair response of FLS as manifested by increased expression of collagens (e.g. COL1A) and TGFb response genes (e.g. TGFBI) Importantly, MerTK/CD206neg and MerTK/CD206pos STMs isolated from the biopsies of the same patient (either with active RA or RA in remission) elicited these divergent FLS responses. These suggest that these two distinct STM populations play opposing role in synovium (pro-inflammatory versus protective).

Co-culture of synovial tissue dendritic cells with autologous peripheral blood memory T-Cells across Active and Remission RA

Project description:To dissect the precise roles of ST-DC2 clusters and ST-iDC3 clusters in T-cell activation, we co-cultured each cluster separately with autologous memory CD4pos T-cells. FACS-sorted ST-DC2 clusters and ST-iDC3 clusters from synovial tissue of active RA or remission RA were co-cultured for 5 days with FACS-sorted autologous blood memory CD4pos T-cells in the presence of anti-CD3 stimulation to mimic TCR activation. We investigated the frequency and phenotype of the resultant co-culture T-cell populations by carrying out single cell sequencing and analysing the output. It was observed that the DC2 and iDC3 group could differentially support distinct T-Cell populations in both frequency, and transcriptional profile.

Evaluation of transcriptomic profiles of peripheral blood myeloid cell subsets of RA patients in remission prior to cDMARD withdrawal, and at the point of flare / 6 months after in sustained remission

Project description:To test the contribution of distinct ST-DC populations to either autoimmunity and inflammation or sustained disease remission, we evaluated the phenotypes of their blood precursors in a human model of disease flare following treatment withdrawal in RA patients in disease remission (the BioRRA study, (Baker et al., 2019)). We investigated the frequency and phenotype of PB DC2 and PB-DC3 of RA patients (n=12) in sustained clinical and ultrasound remission achieved with cDMARDs (Baker et al., 2019) by carrying out, and analysing single cell sequencing data at baseline remission levels, and upon endpoint after treatment withdrawal. We identified that PB DCs differ transcriptionally, but not proportionally, at the baseline of patients who sustain remission, versus those who go on to flare, and at endpoint. We propose that the transcriptomic profile of these peripheral blood DCs could be used as a biomarker of flare in remission RA patients.

Targeted scRNA-seq and AbSeq of human CAR-T cell infusion product from 28 cancer patients

Project description:Immunotherapy using CD19-directed chimeric antigen receptor (CAR)-T cells has shown excellent results for treatment of B-cell leukaemia and lymphoma. To produce CAR-T cells, the patient’s own T cells are isolated from the blood and modified in a laboratory with a genetic vector to express a tumor antigen-directed CAR on its surface. The CAR-T cells are then expanded in numbers and given back to the patient with the aim to eradicate the tumors. However, some patients display primary resistance to CAR-T treatment while others relapse quickly after CAR-T treatment. In this experiment, we seek to understand whether the quality of the individual CAR-T cell product the patients were given can predict outcome to the therapy. We investigate the transcriptional profile of the individual CAR-T infusion products using single-cell RNA sequencing. In this dataset, we identified a T cell subset correlating with response that could be used as an indicator for clinical outcome. Targeted RNA and protein single-cell libraries were obtained using the BD Rhapsody platform (BD Biosciences). In total four separate targeted libraries were produced with 6 patients per library. Sequencing was performed on NovaSeq 6000 S1 sequencer at the SNP&SEQ Technology Platform (Uppsala, Sweden). The raw scRNA-seq data was pre-processed by BD Biosciences using the Rhapsody Analysis pipeline to convert the raw reads into Unique Molecular Identifier (UMI) counts. UMIs are further adjusted within Rhapsody by applying BD’s Recursive Substitution Error Correction (RSEC) and Distribution-Based Error Correction (DBEC) in order to remove false UMIs caused by sequencing or library preparation errors. Pooled samples were deconvoluted using Sample-tag reads. The scRNA-seq and AbSeq counts were loaded, processed and used for clustering and differential gene expression with Seurat v. 4.0.0.

Antibody mRNA-seq repertoire sequencing to study relapses after B-cell depletion therapy

Project description:Rituximab (RTX) is widely used as a first-line therapeutic strategy for patients affected by immune thrombocytopenia (ITP). However, a large proportion of patients relapse after successful treatment. The present NGS assay was done to help find the cause for this relapse on the immune repertoire level. Therefore, we performed antibody repertoire sequencing for three RTX relapse patients with subsequent mutation and clonal analysis, as well as for two patients with ongoing ITP and two healthy donors (HD) with subsequent mutation analysis.

immunoglobulin-mRNA seq repertoire of different human B cell subsets sampled at different time points after pneumovax vaccination to identify the B cell subset responsible for the production of anti-polysaccharides antibodies

Project description:To identify the B cell subset(s) involved in T-independent (TI) responses in humans, we vaccinated healthy individuals with Pneumovax, a model TI vaccine composed of 23 capsular polysaccharides (capPS). High-throughput repertoire sequencing of day 7-plasma cells (PC-d7) and of different B cell subpopulations before and after vaccination was done to search for clonal filiations between anti-capPS PC-d7 clones and the isolated B cell subsets. Ig-Rep seq was done for PC-d7 of 6 vaccinee, and for different subsets sampled at day 0, 7, 14, 28 and 56 from 3 vacinees.
