Comparison between lamina propria macrophages and muscularis macrophages

Project description:Lamina propria and muscularis macrophages, were sorted at steady steate and 2h after oral exposure to an attenuated form of Salmonella, comparison among these populations showed that the muscularis macrophages quckly respond to the presence of intestinal bacteria, upregulating some important tissue protective genes.

Comparison of splenic and small intestine lamina propria macrophages

Project description:The intestinal immune system must elicit robust immunity against harmful pathogens but restrain immune responses directed against commensal microbes and dietary antigens. The mechanisms that maintain this dichotomy are poorly understood. Here we describe a population of CD11b+F4/80+CD11c– macrophages in the lamina propria (LP) that express several anti-inflammatory molecules including interleukin 10 (IL-10), but little or no pro-inflammatory cytokines, even upon stimulation with Toll-like receptor (TLR) ligands. These macrophages induced, in a manner dependent on IL-10, retinoic acid and exogenous transforming growth factor-β, differentiation of FoxP3+ regulatory T cells. In contrast, LP CD11b+ dendritic cells elicited IL-17 production. This IL-17 production was suppressed by LP macrophages, indicating that a dynamic interplay between these subsets may influence the balance between immune activation and tolerance. Splenic or small intestine lamina propria CD11b+11c- cells were isolated for RNA extraction and hybridization on Affymetrix microarrays. We sought to determine the unique genetic profile of small intestine lamina propria CD11b+11c- cells. Keywords: cell type comparison

Transcription profiling of mouse splenic and small intestine lamina propria macrophages

Project description:The intestinal immune system must elicit robust immunity against harmful pathogens but restrain immune responses directed against commensal microbes and dietary antigens. The mechanisms that maintain this dichotomy are poorly understood. Here we describe a population of CD11b+F4/80+CD11câ?? macrophages in the lamina propria (LP) that express several anti-inflammatory molecules including interleukin 10 (IL-10), but little or no pro-inflammatory cytokines, even upon stimulation with Toll-like receptor (TLR) ligands. These macrophages induced, in a manner dependent on IL-10, retinoic acid and exogenous transforming growth factor-Î², differentiation of FoxP3+ regulatory T cells. In contrast, LP CD11b+ dendritic cells elicited IL-17 production. This IL-17 production was suppressed by LP macrophages, indicating that a dynamic interplay between these subsets may influence the balance between immune activation and tolerance.

Age-dependent comparison of transcriptional signature of lamina propria anti-inflammatory macrophages of Il10rb-/- (KO) and Il10rb+/- (het) mice

Project description:We report that colonic lamina propria anti-inflammatory macrophages from Il10rb-/- (KO) mice at 12 weeks possessed significantly high levels of proinflammatory transcripts compared to the ones from Il10rb+/- (het) controls. While the transcriptional profile between macrophages from KO and het mice was comparable at 1 weeks and did not possess significant levels of proinflammatory transcripts, we show that the macrophages from KO mice were enriched for proinflammatory transcripts at 3 weeks compared to the ones from 3 week old het controls. These data indicate that the anti-inflammatory signature of colonic lamina propria macrophages from Il10rb-/- mice is compromized at 3 weeks.
