Project description:Our single-cell transcriptomic profiling study depicted the heterogeneity of human dermal blood vascular endothelial cells and molecularly refined individual blood vessel compartments.
Project description:The purpose of the experiment was to investigate the differentiation state gradient among antigen-experienced CD8+ T cells in healthy human blood. This was a sub-goal within a larger experiment, which aimed to investigate the clonal relationship between CD8+ T cells in blood and skin of matched donors. The blood T cells were sorted as CD8+ T cells (n=4) or CD3+ T cells (n=2), processed according to the 5´prime 10x genomic workflow, and sequenced at NGI Sweden.
Project description:It is unknown whether human lung T cells recirculate or belong to a distinct tissue-specific population. This issue is important for understanding their role in protection against viral infection and their contribution to pathophysiology of lung diseases such as chronic obstructive pulmonary disease. By comparing transcriptional profiles of blood and lung CD8+ T cells, we aimed to reveal specific traits of lung CD8+ T cells. A total of 12 samples was analyzed: 10 patient samples (including 1 technical replicate) and 2 reference samples (including 1 technical replicate). Per patient (in total 3 patients), 3 paired samples were analyzed. These samples were non-naive peripheral blood CD8+ T cells (CD45R0+CD3+CD8+ T cells), memory-type lung CD8+ T cells (CD45R0+CD27+CD3+CD8+ T cells) and effector-type lung CD8+ T cells (CD45R0+CD27-CD3+CD8+ T cells). The reference population consisted of a mix of naive peripheral blood CD8+ T cells from 5 healthy donors.
Project description:We performed the analysis of transcriptional and alternative splicing landscapes for paired decidual and peripheral blood CD8 T cells at the first trimester of human healthy pregnancy by high-throughput mRNA sequencing.
Project description:CD8+ T cells are the primary target of immune checkpoint inhibitor (ICI) therapy in the treatment of melanoma. ICI therapy only benefits a subset of patients and complicating this issue is a reliable prediction method that does not require invasive biopsies. In the hope of remedying this challenge, we conducted single-cell transcriptomic analyses of CD8+ T cells in peripheral blood lymphocytes (CD8-mPBLs) and, importantly, tumor-infiltrating lymphocytes (CD8-mTILs) from 8 patients with metastatic melanoma.
Project description:Single cell transcriptomic analysis of human CD25+ CD127- CD4+ Treg cells and CD25- CD127+ CD4+ Tconv cells isolated from peripheral blood from two different donors
Project description:The ability to monitor anti-tumor CD8+ T cell responses in the blood has tremendous therapeutic potential. However, tracking tumor antigen-specific CD8+ T cells in the blood is challenging due to their small number and limited reagents to track these cells. We asked whether paired single-cell RNA and T cell receptor (TCR) sequencing could be used to detect and characterize “tumor matching” (TM) CD8+ T cells in the blood of advanced melanoma patients using the TCR as a molecular barcode. By leveraging the transcriptome, we characterized these cells, and identified candidate cell surface markers for to enrich this population. These data show that the TCR can be used to identify tumor-relevant cells for characterization, reveal unique transcriptional properties of TM cells, and develop marker panels for tracking and analysis of these cells.
