ABSTRACT: EMG produced TPA metagenomics assembly of the Metagenomes from 11 human infant fecal samples hospitalized in the same intensive care unit (human gut metagenome) data set.
Project description:To go further insight into the involvement of neutrophils in COVID-19 clinical expression, we performed a proteomic analysis of this blood cell type in COVID-19 patients and two non-infected SARS-CoV-2 control groups composed of healthy subjects and ARDS patients hospitalized in intensive care unit (ICU) respectively. All patients were from Guadeloupe and represent a homogeneous population. We have performed a quantitative proteomic study of neutrophiles from French hot spot COVID region, Guadeloupe, confirming the activation of type I IFN pathway and in some target of IFN as TAP proteins, specifically in COVID patients, but not in hospitalized ARDS non-COVID patients and described modification of the NET proteome potentially associated with ARDS.
Project description:Circulating miRNAs in patients who underwent ARDS and needed mechanical ventilation were analyzed by next generation sequencing (NGS) in comparison with patients who had COVID-19 poor symptoms but without intensive care unit requirement.

Project description: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.
