Project description:Human primary monocytes are composed of a minor, more mature CD16+(CD14low/neg) population and a major CD16neg(CD14+) subset. The specific functions of CD16+ vs. CD16neg monocytes in steady state or inflammation remain poorly understood. In previous work we found that IL-12 is selectively produced by the CD16+ subset in response to the protozoan pathogen, Toxoplasma gondii. Here we demonstrated that this differential responsiveness correlates with the presence of an IFN-induced transcriptional signature in CD16+ monocytes already at baseline. Consistent with this observation, we found that in vitro IFN-γ-priming overcomes the defect in IL-12 response of the CD16neg subset. We have anayzed the gene expression profile of primary human CD16+ and CD16neg monocyte subsets cultured for without or with IFN-gamma

Project description:Human and mouse blood each contain two monocyte subsets. Here, we investigated the extent of their similarity using a microarray approach. Approximately 300 genes in human and 550 genes in mouse were differentially expressed between subsets. More than 130 of these gene expression differences were conserved between mouse and human monocyte subsets. We confirmed numerous differences at the cell surface protein level. Despite overall conservation, some molecules were conversely expressed between the two speciesM-bM-^@M-^Y subsets, including CD36, CD9, and TREM-1. Furthermore, other differences existed, including a prominent PPARM-NM-3 signature in mouse monocytes absent in human. Overall, human and mouse monocyte subsets are far more broadly conserved than currently recognized. Thus, studies in mice may indeed yield relevant information regarding the biology of human monocyte subsets. However, differences between the species deserve consideration in models of human disease studied in the mouse. Keywords: Expression profiling by array The two major subsets of monocytes (Ly-6C+ and Ly-6Clo) from 12-week old C57Bl/6 mice were sorted and the RNA extracted and hybridized to Affymetrix GeneChipM-BM-. 430 2.0 arrays. We pooled leukocytes from 5 mice for each sort and sorted 4 separate times for 4 biological replicates. The two major monocyte subsets (CD16- and CD16+) were isolated from venous heparinized blood from apparently healthy human volunteers using MACS technology with all reagents and tools from Miltenyi Biotec. Three separate donors were hybridized three different times to Affymetrix U133 Plus 2.0 array.

Project description:Transcriptomic profile of circulating monocyte subsets in active versus latent tuberculosis
| PRJNA768837 | ENA
Project description:In this analysis, sorted classical (CM), intermediate (IM) and non-classical (NCM) monocyte subsets from children under steady state (healthy, H) and dengue febrile illness (Dengue, D) were analyzed for their transcriptional profiles using RNA seq. The monocyte subsets were sorted from peripheral blood cells after excluding CD3, CD19, CD20, CD56, CD66b and NKp30 positive cells and then gating on HLADR positive population to identify CM, IM and NCM subsets based on surface expression of CD16 and CD14. The transcriptional profile of the three monocyte subsets was separately compared in healthy children, in dengue febrile children and in dengue versus healthy states. This study highlights hierarchy of gene expression in classical, intermediate and non-classical monocytes in healthy and dengue febrile conditions.

Project description:Kawasaki disease (KD) is characterized by a disorder of immune response, and its etiology remains unknown. Monocyte is an important member of body's innate immune system, however its role in KD is still elusive due to its ambiguous heterogeneity and complex functions. Here, scRNA-seq was performed to reveal monocytes heterogeneity in healthy and KD infants. Circulating monocytes were separated from peripheral blood and scRNA-seq was used to transcriptionally profile the monocytes in both healthy and KD infants. Four monocyte subsets are identified in infants, in which three clusters are mainly CD14+CD16- monocytes and one cluster is mainly CD14-CD16+ monocytes. The four monocyte subsets possess different biological functions and represent a relatively linear differentiation. CD14+ monocyte subsets in KD are distinct from that of healthy infants, including one subset expressing FOLR3, S100A12 and IL1R2 and the other expressing MT-TN specifically. Moreover, the CD14+ monocyte subsets in KD are poorly differentiated, and their functions mainly involve neutrophil activation. In conclusion, a relatively comprehensive map of circulating monocyte subsets was plotted for the first time in healthy infants. CD14+ monocyte subsets that are distinct from healthy infants were revealed in KD, which may serve as a target for KD treatment in the future.
