A novel method for characterizing cell-cell interactions at single-cell resolution reveals unique immune signatures in blood T cell-monocyte complexes during infection (Dengue scTCR-Seq)

ABSTRACT: We designed a novel method to study the transcriptome of single cells forming complexes in a high-throughput fashion, without the need for bioinformatic deconvolution. We applied this method to the study of T cells and monocytes forming complexes in blood isolated from individuals with dengue fever, with blood collected at the acute and convalescent phase of infection. We found that the transcriptomic signatures of T cells and monocytes forming complexes significantly overlapped with those identified in T cell-monocyte complexes in active tuberculosis, with upregulation of genes associated with T cell activation, cytotoxicity, cell adhesion and MHC-II. Thus, using our novel method, we identified that T cells and monocyte forming complexes in blood hold unique immune signatures distinct from singlets, and that they may be a previously overlooked valuable biomarker to monitor immune synaptic interactions during infection.

A novel method for characterizing cell-cell interactions at single-cell resolution reveals unique immune signatures in blood T cell-monocyte complexes during infection (ATB scTCR-Seq)

Project description:We designed a novel method to study the transcriptome of single cells forming complexes in a high-throughput fashion, without the need for bioinformatic deconvolution. We applied this method to the study of T cells and monocytes forming complexes in blood isolated from individuals with active tuberculosis, with blood collected at diagnosis and after treatment. We found that the transcriptomic signature of T cells and monocytes forming complexes was associated with TCR/MHC-II immune synaptic features, enrichment for cytotoxic clonally expanded T cells and intermediate monocytes, and - especially at diagnosis - transcriptomic signatures indicating increased immune and metabolic activity. We also found a striking enrichment of “dual-expressing” cells (i.e., co-expressing T cells and monocyte marker genes) in complexes, suggesting RNA exchange occur during T cell-monocyte interactions. Thus, using our novel method, we identified that T cells and monocyte forming complexes in blood hold unique immune signatures distinct from singlets, and that they may be a previously overlooked valuable biomarker to monitor immune synaptic interactions during infection.

Monocytes as endogenous immunologic biosensors: identification of inflammatory, adhesion, and mTOR-related signatures in psoriasis

Project description:Psoriatic monocyte singlets and doublets (MonD) have a distinct gene expression profile compared to singlet control monocytes. Furthermore, there is dysregulation of adhesion markers, tetraspanins, adipocytokines, and mTOR-related genes in singlets and doublets from both psoriatic and control individuals.

RNAseq characterisation of iPSC-derived monocytes, macrophages and dendritic cells and their their primary blood derived counterparts

Project description:As supplies of monocytes, macrophages and dendritic cells from human sources can be scarce or prone to donor variation we established an efficient method to generate induced pluripotent stem cell derived monocytes that in turn could be differentiated into both macrophages and dendritic cells. We used RNA sequencing to profile these from multiple differentiation runs (n=3) and multiple monocyte harvests (n=3-4) and compared them to their blood derived counterparts, blood derived monocyte, monocyte derived macrophages and moncyte derived dendritic cells (from 3 donors).

Notch and TLR signaling coordinate monocyte cell fate and inflammation

Project description:We studied the role of Notch2 signaling in Ly6Chi monocyte cell fate during TLR7-induced acute inflammation. To characterize the gene expression changes involved in monocyte differentiation, we subjected monocyte subsets from peripheral blood of wt and myeloid Notch2 mutant mice after Sham or IMQ treatment to RNA-sequencing and gene expression analysis. We found that Cell-intrinsic Notch2 and TLR7-Myd88 pathways independently and synergistically promote Ly6Clo patrolling monocyte development from Ly6Chi monocytes under inflammatory conditions. At the same time TLR7 stimulation in the absence of functional Notch2 signaling promotes resident tissue macrophage gene expression signatures in monocytes and ectopic differentiation of Ly6Chi monocytes into macrophages and dendritic cells. Thus, Notch2 is a master regulator of Ly6Chi monocyte cell fate and inflammation in response to TLR signaling.

High-Yield Monocyte, Macrophage, and Dendritic Cell Differentiation from Induced Pluripotent Stem Cells

Project description:Differentiation of induced pluripotent stem cells (iPSC) into monocytes, monocyte-derived macrophages (MDM), and monocyte-derived dendritic cells (moDC) represents a powerful tool for studying human innate immunology and developing novel iPSC-derived immune therapies. Challenges include inefficiencies in iPSC-derived cell cultures, labor-intensive culture conditions, low purity of desired cell types, and feeder cell requirements. Here, a highly efficient method for differentiating monocytes, MDMs, and moDCs that overcomes these challenges is described. The process utilizes commercially-available materials to derive CD34+ progenitor cells that are apically released from a hemogenic adherent fraction (HAF). Subsequently, the HAF gives rise to highly pure (>95%), CD34-CD14+ monocytes in 19-23 days and yields 13.5-fold more monocytes by day 35 when compared to previous methods. These iPSC-monocytes are analogous to human blood-derived monocytes and readily differentiate into MDM and moDC. The efficient workflow and increase in monocyte output heightens feasibility for high throughput studies and enables clinical-scale iPSC-derived manufacturing processes.
