Project description:We isolated neutrophils from 11 healthy controls, 12 COIVD-19 patients in ICU and 12 COVID-19 patients from ward and submitted the isolated RNA for RNA sequencing. We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 different cohorts. .

Project description:Individuals infected with SARS-CoV-2 vary greatly in their symptomatology and disease progression, likely as a result of numerous genetic, biological and environmental factors and their complex interactions. Meanwhile, the potential roles of microRNAs (miRNAs) in SARS-CoV-2 infection have not been fully described. MiRNAs have emerged as key post-transcriptional regulators of gene expression, and their dysregulation can be indicative of aberrant immune function. In this study, we characterize the potential roles of mIRNAs in early COVID-19 disease progression. We studied a diverse cohort of 259 patients admitted to hospitals in Abu Dhabi, United Arab Emirates to understand the clinical and biological factors associated with ICU admission during COVID-19 treatment, integrating electronic health records (EHR), global miRNA and RNA expression, and genotyping data. Using EHR, we identified 26 factors correlated with ICU admission, including 8 blood phenotypes such as neutrophil-to-lymphocyte ratio, Interleukin-6, and C-reactive protein levels. Using genome-wide miRNA expression data for a subset of 96 individuals from Southeast Asia and the Middle East and North Africa, we identified 27 miRNAs significantly associated with ICU admission (p < 0.01), and 97 miRNAs associated with at least one of the 8 blood phenotypes. [cross-cor] Integrating expression data for 632 miRNAs and genotyping data for ~260,000 SNPs, we identified 168 significant cis-expression quantitative trait loci (cis-eQTLs), of which 59 were associated with either ICU admission or one of the 8 blood phentoypes. Overall, our findings characterize the miRNA architecture of blood phenotypes during the early stages of COVID-19 infection, identify miRNAs associated with ICU admission and therefore COVID-19 disease severity, and suggest a potential genetic control of miRNA expression during early COVID-19 disease progression.

Project description:Neutrophils play a key role in the pathophysiology of rheumatoid arthritis (RA) where release of ROS and proteases directly causes damage to joints and tissues. Neutrophil function is directly affected by Janus Kinase (JAK) inhibitor drugs, including tofacitinib and baricitinib, which are clinically effective treatments for RA. However clinical trials have reported increased infection rates and transient neutropenia during therapy. The subtle differences in the mode of action, efficacy and safety of JAK inhibitors has been the primary research topic of many clinical trials and systematic reviews, to provide a more precise and targeted treatment to patients. The aim of this study was to determine both the differences in the metabolome of neutrophils from healthy controls and people with RA, and the effect of different JAK inhibitors on the metabolome of healthy and RA neutrophils. Isolated neutrophils from healthy controls (HC) (n=6) and people with RA (n=7) were incubated with baricitinib, tofacitinib or a pan-JAK inhibitor (all 200ng/mL) for 2h. Metabolites were extracted and 1H nuclear magnetic resonance (NMR) was applied to study the metabolic changes. Multivariate analyses and machine learning models show a divergent metabolic pattern in RA neutrophils compared to HC at baseline (F1 score = 86.7%) driven by energy metabolites (ATP, ADP, GTP and glucose). No difference was observed in the neutrophil metabolome when treated with JAK inhibitors. However, JAK inhibitors significantly inhibited ROS production and baricitinib decreased NET production (p-value<0.05). Bacterial killing was not inhibited by JAK inhibitors, indicating their effect on neutrophils is beneficial to inhibit joint damage in RA without impairing host defence. This study highlights altered energy metabolism in RA neutrophils which may explain the cause of their dysregulation in inflammatory disease.

Project description:The number of organ failures at intensive care unit (ICU) admission is the main prognostic factor in septic shock. The aim was to assess classical clinico-biological parameters evaluating organ dysfunctions at ICU admission, combined with proteomics analysis, on day-30 mortality in critically ill onco-hematology patients admitted to the ICU for septic shock.

Project description:To investigate the difference among neutrophils circulating in the blood, and those infiltrating in the metastatic organ, we isolated peripheral blood (PB) and lung neutrophils from AT3 tumor-bearing mice. Total RNA was isolated from neutrophils and the transcriptional profiles of neutrophils were analyzed by RNA seq.

Project description:Characterization of three hepatocyte cell lines (2 parental and 1 clone), under two different media conditions. Parental cell lines HepG2 and HC-04, single cell cloned from HC-04 defined as HC-04.J7. The goal of the project initially was to investigate the invasion of hepatocytes by Plasmodium falciparum sporozoites, and once found that the HC-04 cell had a higher invasion than HepG2, single cell isolates were generated from HC-04 before being expanded. The resulting HC-04.J7 isolate further improved the invasion rate. Transcriptomic and proteomic data sets were generated from all cell lines in both media, than analyzed for potential receptors or biochemical pathways that play a role in the increased invasion of HC-04 and specifically, HC-04.J7.

Project description:This study performed single-cell RNA sequencing (scRNA-seq) analyses on peripheral blood neutrophils from cystic fibrosis (CF) patients and healthy controls (HC) in their native state and LPS-activated state. Differences in global gene transcription were interrogated and compared. Results demonstrate that CFTR loss of function in CF neutrophils led to abnormal immune programming, exemplified by precocious priming at their native state, and abnormal immune response to LPS.
