Effects on expression profile of acute congestive heart failure (ACHF) patients monocytes by treatment with conventional drugs.

ABSTRACT: Several studies have shown the importance of immune and inflammatory mediators in the pathogenesis of heart failure. In clinical practice has been observed that many conventional drugs can modulate circulating levels of these mediators. Despite, there is poor understanding of the precise mechanisms of these drugs in regulating immune and inflammatory systems. Blood monocytes were isolated from 6 hospitalized patients in Intensive Cardiology Care Unit (ICCU) with symptomatic acute congestive heart failure (ACHF) (NYHA Class III-IV) before and after treatment with conventional drugs (ARBs, ACEIs, diuretics, and beta-blockers). Gene expression analysis (n=11) using whole human genome microarray showed that pharmacological treatment abrogate inflammatory activation of monocytes. The inflammatory response network constructed with Ingenuity Pathway Analysis (IPA) indicates the “TNFR1 signaling” as the most significantly modulated after pharmacological treatment and the pro-inflammatory cytokine TNF-alpha associated with more than a fifth of genes considered.

In this study, we analyzed the expression profiles of 6 biological replicates of blood monocytes from ACHF patients pre- and post-treatment with conventional drugs (ARBs, ACEIs, diuretics, and beta-blockers). All RNAs from pre-treatment monocytes were hybridized against RNAs from post-treatment RNAs. We performed a total of 11 technical replicates.

Inflammatory type 2 conventional dendritic cells contribute to murine and human cholangitis

Project description:Cholangitis mouse models were characterised by selective intrahepatic expansion of type 2 conventional dendritic cells, whereas plasmacytoid and type 1 conventional dendritic cells were not expanded. Expansion of type 2 conventional dendritic cells in human PSC lesions was confirmed by histology. Depletion studies revealed a pro-inflammatory role of type 2 conventional dendritic cells. Single-cell transcriptomics confirmed inflammatory maturation of the intrahepatic type 2 conventional dendritic cells and identified dendritic cell-derived inflammatory mediators.

Congestive heart failure in dog

Project description:Canine tachycardia-induced cardiomyopathy caused by several weeks of rapid ventricular pacing is a well-established animal model of congestive heart failure. However, little is known about the underlying changes in gene expression that occur in the canine myocardium after the induction of heart failure. This project aims to compare expression profiles in left ventricular free wall samples from control dogs and dogs with pacing-induced heart failure on the custom MuscleChip. Keywords: other

Baricitinib attenuates the proinflammatory phase1 of COVID-19 driven by lung-infiltrating monocytes

Project description:COVID-19 patients are generally asymptomatic during initial SARS-CoV-2 replication, but may suffer severe immunopathology after the virus has receded and blood monocytes have infiltrated the airways. In the bronchoalveolar lavage fluid from patients with severe COVID-19, lung-infiltrating monocytes expressed high mRNA levels encoding inflammatory mediators, including CXCL8and IL-1ß, and contained SARS-CoV-2transcripts. To study this process in more depth, we developed a novel organotypic model whereby primary human blood monocytes are transmigrated across a differentiated human lung epithelium infected by SARS-CoV-2. Infiltrating monocytes acquiredSARS-CoV-2 from the epithelium and upregulated expression and secretion of inflammatory mediators includingCXCL8 and IL-1ß, mirroring in vivo data. The JAK1/2inhibitor baricitinib gained emergency use authorization by the FDA for the treatment of COVID-19 originally in combination with the antiviral remdesivir, and recently as a stand-alone treatment. To explore the mechanisms by which baricitinib alone or in combination with remdesivir may result in more favorable disease outcomes, we leveraged this model to characterize viral burden, gene expression and inflammatory mediator secretion by lung epithelial cells and infiltrating monocytes. As expected, remdesivir decreased viral burden in both the epithelium and monocytes, while baricitinib enhanced antiviral signaling and decreased specific inflammatory mediators in monocytes. Combined use of baricitinib and remdesivir enhanced the rate of virus clearance from SARS-CoV-2-positivemonocytes. Taken together, baricitinib enhances the antiviral state of monocytes infiltrating the COVID-19 lung, while decreasing the expression of inflammatory mediators, thus limiting the likelihood of a cytokine storm and ensuing acute respiratory distress syndrome (ARDS).

Control and Congestive Heart Failure

Project description:Congestive heart failure was done by artificial myocardial infarction. After extracting total RNA from control and infarcted ventricles with Triazol, messenger RNA was isolated with Qiagen mRNA isolation kit. About 1.5ug poly A+ RNA was taken for probe preparation. Probe was labeled with Alexa Fluor 546 and 657. Labeled probes were hybridized with Qiagen rat unigene oligo library. After 2 low and 1 high stringency washes Prolong Antifade was added to the slides to prevent bleaching effect. The data ratio was normalized using a location and intensity dependent Lowess formula.

Human Toll-Like Receptors Pathway Array Data

Project description:Endothelial cell (EC) Toll-like receptor 2 (TLR2) activation upregulates the expression of inflammatory mediators and of TLR2 itself, and modulates important endothelial functions, including coagulation and permeability. We defined TLR2 signaling pathways in ECs, and tested the hypothesis that TLR2 signaling differs in ECs and monocytes. We found that ERK5, heretofore unrecognized as mediating TLR2 activation in any cell type, is a central mediator of TLR2-dependent inflammatory signaling in HUVEC, primary human lung microvascular ECs and human monocytes. Additionally, we observed that whereas MEK1 negatively regulates TLR2 signaling in EC, MEK1 promotes TLR2 signaling in monocytes. We also noted that activation of TLR2 led to the upregulation of intracellularly expressed TLR2 and inflammatory mediators via NF-κB, JNK and p38-MAPK. Finally, we found that p38-MAPK, JNK, ERK5 and NF-κB promote the attachment of human neutrophils to lung microvascular EC that were pretreated with TLR2 agonists. This study newly identifies ERK5 as a key regulator of TLR2 signaling in ECs and monocytes, and indicates that there are fundamental differences in TLR signaling pathways between EC and monocytes.
