Single cell mRNA profiles of CSF from children with BM

Project description:Purpose: Characterizing the cell heterogeneity of CSF during the BM development in children. Method: CSF samples were obtained via lumbar puncture from numbers of BM patients in different stages of disease progression. CSF cells were separated by direct centrifugation. A mimic assay based on QUARTZ-SEQ2 was adopted here for library preparations for scRNA-seq. Single CSF cells were sorted into two pre-prepared 384-well plates with cell lysis buffer by flow cytometry, in which each well contained a unique cell barcoding primer. An independent scRNA-seq library was constructed for 768 cells of each CSF sample, and was sequenced using a HiSeq X Ten sequencing system (Illumina). The generation of a cell-count matrix were processed in the combined workflow of UMI-tools and STAR. Secondary analysis were handled by Seurat package. Results: The heterogeneities of CSF cells in BM progression were deciphered. Multiple immune cell clusters in CSF were identified, including two neutrophils, two monocytes, one macrophage, four myeloid dendritic cells, five T cells, one natural killer cell, one B cell, one plasmacytoid dendritic cell, and one plasma cell subtype. Their population profiles and dynamics in the initial onset, remission, and recovery stages during BM progression were also characterized. Conclusions: This study conducted an in-depth exploration of the heterogeneities of CSF cells in BM progression, which provided novel insights into immune cell engagement in acute CNS infection.

Bulk transcriptome sequencing (bulkRNA-seq) of human cerebrospinal fluid (CSF) cells in the bacterial meningitis (BM) of children

Project description:Purpose: Profiling the bulk transcriptomes of CSF cells in sepsis-developed BM progression. Methods: The total RNA of CSF cells from BM patients were extracted, and constructed into cDNA library. Raw data of mRNA profiles were sequenced by paired-end strategy. Gene-counts were generated through handling sequencing data with the combined workflow of UMI-tools, STAR, Subread package and Samtools. Results: Successfully acquirng multiple bulk-transcriptomic profiles of CSF cells from BM patients in different sepsis conditions.

Microarray analysis of WT bone marrow myeloid progenitors, BM cultured with GM-CSF and M-CSF, and monocytes treated with GM-CSF

Project description:Analysis of genes induced in DC precursors and in BM cells and monocytes treated with GM-CSF For progenitor arrays, bone marrow progenitors (CMP, GMP, CDP, and pre-cDC) were harvested from WT C57Bl/6 mice. For culture arrays, BM was cultured in the presence of GM-CSF or M-CSF and adherent and non-adherent cells sorted. For monocyte cultures, sorted BM monocytes were treated with GM-CSF for 0, 24 or 48 hours.
