Frontline Science: Extracellular CIRP generates a proinflammatory Ly6G+ CD11bhi subset of low-density neutrophils in sepsis.

abstract：:Single-cell RNA sequencing (scRNA-seq) is a powerful new technology allowing the analysis of transcriptomes from individual cell and is ideally suited to dissect immune cell heterogeneity. ScRNA-seq has already been applied to identify novel immune cell subsets, elaborate cellular differentiation trajectories, and elu...
