Pro-inflammatory monocyte phenotype during acute progression of cerebral small vessel disease

ABSTRACT: The aetiology of cerebral small vessel disease (SVD) remains elusive, though currently evidence is accumulating that inflammation contributes to its pathophysiology. In this prospective high-frequency imaging study, we showed that the incidence of acute SVD progression coincides with a functional and transcriptional pro-inflammatory monocyte phenotype. To detect SVD progression, individuals with SVD underwent monthly magnetic resonance imaging (MRI) for 10 consecutive months. RNA sequencing revealed a pro-inflammatory monocyte signature with upregulation of the EGR2 gene. Collectively, we showed that individuals with progressive SVD have pro-inflammatory circulating monocytes characterized by an augmented cytokine production capacity and a pro-inflammatory transcriptional signature.

Differential expression in the cortex and white matter of patients with cerebral small vessel disease (SVD)

Project description:In this study, we performed the first genome-wide expression profiling of post-mortem brains of a cohort of patients deceased from SVD and compared them to age-matched normal controls. Normal-appearing frontal temporal and occipital cortical and subcortical brain samples were dissected at autopsy from 5 patients diagnosed with pure SVD and 5 control patients without neurological disease and immediately frozen.

Platelet-derived transcription factors license human monocyte inflammation

Project description:CD14+ monocytes, the predominant population in human blood, are primarily engaged in host defense and pro-inflammatory cytokine responses. Aberrant monocyte activity causes life-threatening cytokine storms, while dysfunctional monocytes lead to 'immunoparalysis.' Understanding the mechanisms controlling monocyte functions is therefore paramount. Here, we reveal platelets' vital role in human monocytes' pro-inflammatory responses. Natural low platelet counts in patients with immune thrombocytopenia (ITP) , platelet depletion in healthy human monocytes, or in vivo platelet depletion in mice, result in monocyte immunoparalysis, characterized by reduced pro-inflammatory gene expression and weakened cytokine responses to immune challenge. Remarkably, supplementation with fresh platelets reverses monocyte immunoparalysis. In mice, thrombocytopenia results in down-regulation of myeloid innate immune genes, and compromised host defense transcriptional programs in monocytes despite normal responses to LPS. Platelets control monocyte cytokines independently of traditional cross-talk pathways, acting as reservoirs of transcription factors like NF?B and MAPK p38. We pinpointed a vesicle-derived NF?B2 transfer to human monocytes by mass spectrometry-based proteomics. Functionally, platelets proportionally restored impaired cytokine secretion in human monocytes lacking MAPK p38a and NF?B p65 and NF?B2. We unveil the intercellular transfer of inflammatory regulators, positioning platelets as central checkpoints in monocyte-mediated inflammation.

The Transcriptome Of Cmml Monocytes Is Highly Inflammatory And Reflects Leukemia-Specific And Age-Related Alterations

Project description:Chronic myelomonocytic leukemia (CMML) is an aggressive myeloid neoplasm of older individuals characterized by persistent monocytosis. Somatic mutations in CMML are heterogeneous and only partially explain the variability in clinical outcomes. Recent data suggest that cardiovascular morbidity is increased in CMML and contributes to reduced survival. Clonal hematopoiesis of indeterminate potential (CHIP), the presence of mutated blood cells in hematologically normal individuals, is a precursor of age-related myeloid neoplasms and associated with increased cardiovascular risk. To isolate CMML-specific alterations from those related to aging, we performed RNA sequencing and DNA methylation profiling on purified monocytes from CMML patients and from age-matched (old) and young healthy controls. We found that the transcriptional signature of CMML monocytes is highly pro-inflammatory, with upregulation of multiple inflammatory pathways, including tumor necrosis factor, IL-6 and IL-17 signaling, while age per se does not significantly contribute to this pattern. We observed no consistent correlations between aberrant gene expression and CpG island methylation, suggesting that pro-inflammatory signaling in CMML monocytes is governed by multiple and complex regulatory mechanisms. We propose that pro-inflammatory monocytes may contribute to cardiovascular morbidity in CMML patients, and promote progression by selection of mutated cell clones. Our data raise questions whether asymptomatic CMML patients may benefit from monocyte-depleting or anti-inflammatory therapies.

Transcription profiling of human HCMV-Infected monocytes study 2

Project description:Human cytomegalovirus induces a pro-inflammatory monocyte following infection. To begin to address how HCMV induces these rapid changes in infected monocytes, we examined the transcriptome of infected monocytes. Global transcriptional profiling using cDNA microarrays revealed a significant number of pro-inflammatory genes were upregulated within 4 hours post infection. Experiment Overall Design: To begin to globally define the HCMV-induced changes in monocyte function, we performed a transcriptome analysis. Specifically, a cDNA microarray containing 12,626 unique probe sets was utilized to assess the modulation of the monocyte transcriptome at 4 hours post infection. A total of 6 replicates from mock-infected and 6 replicates from HCMV-infected monocytes were analyzed in this study.

Proteomic analysis of human atherosclerotic plaque supernatants in response to treatment with monocyte extracellular vesicles

Project description:Extracellular vesicles (EV) convey biological messages through their cargoes. Herein we focus on monocyte/platelet aggregates characteristic of several cardiovascular diseases with an analysis of monocyte-derived EV (mEVs) effects on the atherosclerotic plaque. Monocyte preparations were stimulated with TNF-α in presence or absence of prostacyclin and EVs isolated via centrifugation. EV physical characteristics were determined by Nanoparticle Tracking analysis while surface profile was analysed using imaging flow cytometry. Atherosclerotic plaques from 5 patients undergoing endarterectomy were cultured with or without mEVs. Cytokines and proteins released in the culture media were measured by multiplex ELISA and mass spectrometry. Proteomic of mEVs prepared in different incubation settings was also conducted. Monocyte isolation yielded ~80% platelet-monocyte aggregates. TNF-α stimulation produced CD14+ EVs as well as a subset bearing the CD41 marker for platelets (CD14+/CD41+). Prostacyclin addition did not modulate monocyte/platelet aggregates, but impacted on mEV numbers. Addition of TNF-α mEVs on atherosclerotic plaque fragments impacted on general protein release (19 upregulated and 7 downregulated) and elevated cytokine release. mEVs generated by TNF-α and prostacyclin produced minimal changes on plaque reactivity. Proteomic analysis of mEVs revealed a distinctive composition when the cell preparation was activated with TNF-α alone or with prostacyclin. In conclusion, mEVs activate the atherosclerotic plaque. Attenuating platelet activation has an effect on EV composition with downstream modulation of their pro-inflammatory actions. EV heterogeneity reflects the mode of activation of the cell of origin and may differently contribute to the development and progression of atherosclerosis.
