Single-cell assay examining chromatin accessibility reveals transcriptional regulatory variation in the proinflammatory milieu of uremia

Project description:A single-cell assay for transposase-accessible chromatin with high-throughput sequencing (scATAC-seq) was applied to compare the single-cell chromatin accessibility profiles of peripheral blood mononuclear cells (PBMCs) that were obtained from healthy volunteers and uremia patients. Besides, we further revealed the biological functions and regulatory modes of the uremia-related transcription factors (TFs). We principally identified 8 leukocytic clusters using promoter sums of cell type-specific marker genes. Representative TF motifs related to immune cell phenotype identification were found. The comparison of cells from uremia patients and healthy individuals revealed differential candidate TF motifs driving the uremia-associated transcriptomic signature changes, thereby resulting in variation of multiple immune-inflammatory pathways, virus infection-related pathways, and tumor-associated pathways.Our findings reveal transcriptional regulatory variation in uremia-derived PBMCs from an epigenetic perspective, providing a foundational framework for studies examining proinflammatory mechanisms in uremia and establishing a foundation for future research investigating epigenetic therapy.

Plasma induced signatures reveal an extracellular milieu possessing an immunoregulatory bias in treatment naïve inflammatory bowel disease

Project description:The complex milieu of inflammatory mediators associated with many diseases is often too dilute to directly measure in the periphery, necessitating development of more sensitive measurements suitable for mechanistic studies, earlier diagnosis, guiding selection of therapy, and monitoring interventions. Previously, we determined that plasma of recent-onset (RO) Type 1 diabetes (T1D) patients induce a proinflammatory transcriptional signature in fresh peripheral blood mononuclear cells (PBMC) relative to that of unrelated healthy controls (HC). Here, using an optimized cryopreserved PBMC-based protocol, we apply this approach to inflammatory bowel disease by examining groups of Crohn's disease (CD) and ulcerative colitus (UC) patients. The induced plasma induced signatures are compared to those of Type 1 diabetes patients (RO T1D) as well as unrelated healthy controls (uHC).
