Single-cell profiling identifies ACE+ granuloma macrophages as a non-permissive niche for intracellular bacteria during persistent Salmonella infection

Project description:Macrophages mediate key antimicrobial responses against intracellular bacterial pathogens, such as Salmonella enterica. Yet, they can also act as a permissive niche for these pathogens to persist in infected tissues within granulomas, which are immunological structures comprised of macrophages and other immune cells. We apply single-cell transcriptomics to investigate macrophage functional diversity during persistent Salmonella enterica serovar Typhimurium (STm) infection in mice. We identify determinants of macrophage heterogeneity in infected spleens and describe populations of distinct phenotypes, functional programming, and spatial localization. Using a STm mutant with impaired ability to polarize macrophage phenotypes, we find that angiotensin converting enzyme (ACE) defines a granuloma macrophage population that is non-permissive for intracellular bacteria and their abundance anticorrelates with tissue bacterial burden. Disruption of pathogen control by neutralizing TNF is linked to preferential depletion of ACE+ macrophages in infected tissues. Thus ACE+ macrophages have limited capacity to serve as cellular niche for intracellular bacteria to establish persistent infection.

Expression data from RAW264.7 cells infected with wild-type vs srfJ mutant Salmonella enterica serovar Typhimurium

Project description:SrfJ is an effector of the type III secretion systems of the Gram-negative intracellular pathogen Salmonella enterica serovar Typhimurium. To study the effects of this effector on global gene expression in host cells, we have infected murine RAW264.7 macrophages with two strains of Salmonella enterica serovar Typhimurium. The comparison between cells infected with the wild-type strain and cells infected with a srfJ mutant revealed a number of genes that are differentially expressed when SrfJ is present.

Expression analysis of Salmonella enterica serovar Typhimurium UK1 delta-iacP mutant

Project description:Investigation of whole genome gene expression level changes in a Salmonella enterica serovar Typhimurium UK1 delta-iacP mutant, compared to the wild-type strain. IacP is resoponsible for the secretion of virulence effector proteins via the type III secretion system, thereby contributing the virulence of S. Typhimurium. The mutants analyzed in this study are further described in Kim et al. 2011. Role of Salmonella Pathogenicity Island 1 Protein IacP in Salmonella enterica Serovar Typhimurium Pathogenesis. Infection and Immunity 79(4):1440-1450 (PMID 21263021). A chip study using total RNA recovered from two separate wild-type cultures of Salmonella enterica serovar Typhimurium UK1 and two separate cultures of a mutant strain, Salmonella enterica serovar Typhimurium UK1 delta-iacP. Each chip measures the expression level of 4,302 genes from Salmonella enterica serovar Typhimurium.

Integrated genomics of Crohn’s disease risk variant identifies a role for CLEC12A in antibacterial autophagy

Project description:Using integrated genomics we identify a role for CLEC12A in antibacterial autophagy. Clec12a-/- mice are more susceptible to bacterial infection and CLEC12A deficient cells exhibit impaired antibacterial autophagy. We used transcriptional profilinf to understand the role of CLEC12A in the response to Salmonella and Listeria. Bone marrow-derived macrophages from WT or Clec12a-/- mice were infected with Salmonella enterica serovar Typhimurium or Listeria monocytogenes. Cells were harvested at 0,3,6, and 24hours post-infection for RNA analysis. Please note that single-end sequencing was performed but two files: R1 files that contained the sample barcodes (19 or 17bp reads) and R2 files that contained the single-end-sequenced 46bp cDNA reads were generated. Since the barcode info is mostly redundant, only R2 reads were submitted (described in 'raw_file_readme.txt').
