Comparison of gene expression profiles between human and mouse monocyte subsets [human data]

ABSTRACT: 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 species’ subsets, including CD36, CD9, and TREM-1. Furthermore, other differences existed, including a prominent PPARγ 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

However, differences between the species deserve consideration in models of human disease studied in the mouse. 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 GeneChip® 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.

Transcriptome profile of human dermal macrophages and monocyte-derived macrophages

Project description:DC, monocyte and macrophage networks are evolutionarily conserved but the distinct subsets have been difficult to distinguish due to shared overlapping phenotypic markers between the cells. Using transcriptome microarray profiling of human and mouse mononuclear phagocyte subsets, we have distinguished human dermal DCs from monocyte-derived cells and macrophages. Gene Expression from total RNA from human dermal macrophages, epidermal LCs and CD14+ cells subsets purified by FACS

NIMH Human Middle Temporal Gyrus (MTG) Cell Types

Project description:<p>Elucidating the cellular architecture of the human neocortex is central to understanding our cognitive abilities and susceptibility to disease. In this study, we applied single nucleus RNA sequencing to perform a comprehensive analysis of cell types in the middle temporal gyrus of human cerebral cortex. We identify a highly diverse set of excitatory and inhibitory neuronal types, many of which are relatively sparse. Additionally, we found that excitatory types are less layer-restricted than expected based prior knowledge from cell morphologies and from mouse studies. Comparison to a similar mouse cortex single cell RNA-sequencing dataset revealed a surprisingly well-conserved cellular architecture that enables matching of homologous types and predictions of human cell type properties. Despite this general conservation, we also find extensive differences between homologous cell types in human and mouse, including dramatic alterations in proportions, laminar distributions, gene expression, and morphology. These species-specific features emphasize the importance of directly studying human brain.</p> <p>This study conducted by the Allen Institute for Brain Science was supported by the Allen Institute for Brain Science and by US National Institutes of Health grant U01 MH114812-02 to E.S.L.

Transcriptome profiles of mouse and human monocyte and dendritic cell subsets (human data)

Project description:Dendritic cells (DCs) are critical in mediating immunity to pathogens, vaccines, tumors and tolerance to self. Significant progress has been made in the study of DC subsets in murine models but the translation of these findings to human DC immunobiology has not been fully realized. Murine splenic CD8+ DC and CD103+ DC possess potent antigen cross-presenting capacity. Although recent evidence points to human blood CD141+ DCs as the functional equivalent of CD8+ DC, the precise identity of the human migratory cross-presenting DC has remained elusive. We performed phenotypic and functional analyses to interrogate the DC compartment of human non-lymphoid tissues and identified three distinct subsets: i) CD141high DCs, ii) CD1c DCs and iii) CD14+ DCs. Only CD141high DCs were capable of cross-presenting soluble antigen. Comparative transcriptome analysis of steady state monocyte and DC subsets between mouse and human confirmed conservation between species, aligning the following subsets together: i) human CD141high DCs with mouse CD8+ and CD103+ DCs, ii) human CD1c+ DCs with mouse CD4+ DCs and iii) human CD14+ DC with mouse monocyte subsets. The lack of positive association between human CD1c+ DCs and mouse non-lymphoid tissue CD11b+ DCs highlights heterogeneity and predicts the existence of a monocyte-like cell within the CD11b+ DCs.
