Project description:<p>Given that hepatitis B virus (HBV)-related hepatocellular carcinoma (HBV-HCC) exhibits unique gut microbial and metabolic characteristics that influence the immunosuppressive tumor microenvironment, a better understanding of the correlations among gut microbiota, metabolism, and immunosuppressive responses may help predict the occurrence and prognosis of HBV-HCC. This project is expected to analyze the metabolic characteristics in fecal and peripheral blood plasma samples from different patient populations.</p>
Project description:STING agonists are in clinical development, yet their mechanisms of action remain unclear. We used single cell RNA sequencing (scRNA-seq) to analyze response to ADU-S100 in a mesothelioma patient specimen ex vivo.
Project description:This dataset comprises TCR-seq data from peripheral blood CD4+ and CD8+ T cells of head and neck squamous cell carcinoma (HNSCC) patients and healthy donors. Viable peripheral blood mononuclear cells (PBMCs) were sorted into CD45+CD3+CD4+ (CD4+ T cells) and CD45+CD3+CD8+ (CD8+ T cells) subsets, and RNA was isolated using the Qiagen AllPrep DNA/RNA Micro kit. TCR libraries were prepared with the SMART-Seq Human TCR-seq with UMIs kit (Takara Bio) and sequenced on an Illumina NovaSeq X Plus platform. This dataset includes samples from 27 tumor patients and five healthy donors (HDs). The study aims to investigate the phenotype, function, and spatial localization of T cells in HNSCC patients. This peripheral blood dataset focuses on characterizing circulating immune determinants of anti-HNSCC immunity and linking circulating T cell clones to those identified in patient-matched tumor scRNA-seq data.
Project description:C1q expression increases significantly in the peripheral blood of patients with active tuberculosis compared to healthy controls and individuals with latent TB infection. The percentage of C1q-expressing CD14 positive cells is significantly increased in active TB patients. C1q expression in the peripheral blood correlates with sputum smear positivity in tuberculosis patients and is reduced after anti-tuberculosis chemotherapy. Notably, receiver operating characteristic analysis showed that C1qC mRNA levels in peripheral blood efficiently discriminate active from latent tuberculosis infection and healthy controls. Additionally, C1qC protein level in pleural effusion shows improved power in discriminating tuberculosis from non-tuberculosis pleurisy when compared to other inflammatory markers, such as IL-6 and TNF-α C1q expression correlates with active disease in human tuberculosis. C1q could be a potential diagnostic marker to discriminate active tuberculosis from latent tuberculosis infection as well as tuberculosis pleurisy from non-tuberculosis pleurisy.
Project description:We applied high-throughput sequencing of the IGH repertoire in peripheral blood and bone marrow (BM) of a primary immunodeficiency patient. We obtained 325994 IGH sequences from the BM sample and 72597 IGH sequences from the peripheral blood. After comparing with IMGT/GENE-DB database (http://www.imgt.org), we found obviously increased CDR3 clonality in the patient BM as compared to his peripheral blood. Furthermore, the frequency of IgG transcripts in the patient BM was higher than that in the peripheral blood while the frequency of IgM transcripts was similar.
Project description:Guillain-Barré syndrome (GBS) is an immune-mediated peripheral neuropathy that debilitates the voluntary and autonomous response of the patient. In this study the transcriptome of peripheral blood mononuclear cells from a GBS patient and her healthy twin were compared to discover possible correlates of disease progression and recovery.
