Project description:Purpose: Using single-cell RNA sequencing to explore the common and unique pathways between progressive (SarcP) and remitting (SarcR) sarcoidosis as well as chronic beryllium disease (CBD) and sarcoidosis, focusing on macrophages and macrophages subpopulations (recruited vs. resident). Methods: We used scRNA-seq to analyze BAL cells from SarcP (N=2), SarcR (N=2), and CBD (N=3) compared to beryllium sensitized non-diseased subjects (BeS; N=2) or healthy control (Con; N=4). The controls were from Mould KJ, et al. Airspace Macrophages and Monocytes Exist in Transcriptionally Distinct Subsets in Healthy Adults. Am J Respir Crit Care Med 2020. We used the R package Seurat to project cells unto Uniform Manifold Approximation and Projection (UMAP) 2D space, identify cell clusters, and detect differentially expressed (DE) genes. Results: We focused our analysis on macrophages (excluding cell clusters going through the cell cycle). We first compared disease groups to healthy control Using False Discovery Rate (FDR) adjusted p<0.05 and absolute log fold change (log FC)>0.25. We identified 191, 242, and 234 DE genes within all macrophages for the comparisons of SarcP vs. Con, SarcR vs. Con, and CBD vs. Con, respectively, with 82 genes common to all three comparisons; 47 out of the 82 genes were common to all comparisons in regards to recruited macrophages. Conclusions: We focused this first single-cell transcriptome study in granulomatous lung disease on macrophages. This study offers investigators cell-specific transcriptional changes (genes and networks/pathways) to consider mechanisms of granulomatous disease and as potential drug targets.

Project description:The goal of this study was to investigate and correlate differential methylation and expression in cells from the target organ in non-infectious granulomatous lung diseases, specifically sarcoidosis and chronic beryllium disease (CBD). To that end, cells were collected from patients via bronchoalveolar lavage (BAL), and extracted nucleic acids were hybridized to genome-wide arrays. We conclude that there are many genes that are both differentially methylated and expressed in the BAL fluid of patients with granulomatous lung disease. We identified 2,726 differentially methylated CpGs mapping to 1,944 unique genes when comparing CBD patients to beryllium-sensitized (BeS) individuals without disease. 69% of these genes were also differentially expressed in CBD. Sarcoidosis patients exhibited directional consistency at many loci, but genome-wide significance was not achieved, likely due to heterogeneity in the patient population.

Project description:We employed a single cell RNA sequencing (scRNA-seq) approach to describe the cells and communication networks characterizing granulomatous lymph nodes of TB patients. When mapping cells from individual patient samples, we uniformly identify several cell types that characterize granulomas. Whether high or low Mtb burden, overall we find the T cell cluster to be the most abundant. Other cell clusters that are uniformly detected, but that vary dramatically in abundance amongst the individual patient samples, are the B cell, plasma cell and macrophage/dendrocyte and NK cell clusters. When we combine all our scRNA-seq data from our current 23 patients (to gain greater n), we distinguish T, macrophage, dendrocyte and plasma cell subclusters. The sizes of these subclusters also varies dramatically amongst the individual patients. In comparing FNA composition we noted trends in which T cell populations and macrophage/dendrocyte populations were negatively or positively correlated with NK cell populations. In addition, we discovered that the scRNA-seq pipeline detects Mtb RNA transcripts and associates them with their host cell’s transcriptome, thus identifying individual infected cells. The number of infected cells also varies dramatically in abundance amongst the patient samples. CellChat analysis identified predominating signaling pathways amongst the cells comprising the various granulomas.
