Project description:To study the transcriptional profile of patients with acute RSV or Influenza infection,children of median age 2.4 months (range 1.5-8.6) hospitalized with acute RSV and influenza virus infection were offered study enrollment after microbiologic confirmation of the diagnosis. Blood samples were collected from them within 42-72 hours of hospitalization. We excluded children with suspected or proven polymicrobial infections, with underlying chronic medical conditions (i.e congenital heart disease, renal insufficiency), with immunodeficiency, or those who received systemic steroids or other immunomodulatory therapies. The RSV cohort consisted of 51 patients with median age of 2 months (range 1.5-3.9) and the influenza cohort had 28 patients with median age of 5.5 months (range 1.4-21). Control samples were obtained from healthy children undergoing elective surgical procedures or at outpatient clinic visits. To exclude viral co-infections we performed nasopharyngeal viral cultures of all subjects. We recruited 10 control patients for the RSV cohort with median age of 6.7 months (range 5-10), and 12 control patients for the influenza cohort with median age of18.5 months (range 10.5-26). We used microarrays to obtain the transcriptional profile of PBMCs from patients with acute RSV or Influenza infection and compared these signatures with the transcriptional profile of primary airway epithelial cells infected with RSV or Influenza.

Project description:Acute respiratory tract viral infections (ARTI) cause significant morbidity and mortality. While CD8 T cells are fundamental to the host response, the transcriptional alterations underlying anti-viral mechanisms within these cells, and the links to clinical characteristics, remain unclear. The transcriptional circuitry in CD8 T cells from acutely ill pediatric patients with influenza-like illness was distinct for different viral pathogens. We used microarray analysis to profile sorted CD8 T cells from PBMCs of various influenza-like illness patients.

Project description:Analysis of transcriptional profiles in whole blood from children < 2 years of age (and healthy matched controls) with RSV, rhinovirus and influenza infection. The hypothesis tested is that transcriptional profile heterogeneity will reflect patient clinical heterogeneity and that RSV infection induces a distinct host response compared with influenza and rhinovirus infection Total RNA extracted from whole blood (lysed in Tempus tubes) drawn from individual pediatric patients with acute RSV, influenza and Rhinovirus lower respiratory tract infection. A total of 241 samples are analyzed: 135 with acute RSV LRTI, 30 with Rhinovirus LRTI, 16 with influenza LRTI, 39 age-sex matched healthy controls and 21 samples obtained one month after the acute hospitalization in children with RSV. Samples GSM1226237-GSM1226272, which were hybridized to Platform GPL10558, were normalized separately from the other Samples in this Series, which were hybridized to Platform GPL6884. 'GSE38900_non-normalized_GSM1226237-GSM1226272.txt.gz' includes the non-normalized data for Samples GSM1226237-GSM1226272; 'GSE38900_non-normalized.txt.gz' includes the non-normalized data for the other Samples.

Project description:Although most SARS-CoV-2-infected individuals experience mild COVID-19, some patients suffer from severe COVID-19, which is accompanied by acute respiratory distress syndrome and systemic inflammation. To identify factors driving severe progression of COVID-19, we performed single-cell RNA-seq using peripheral blood mononuclear cells (PBMCs) obtained from healthy donors, patients with mild or severe COVID-19, and patients with severe influenza. Patients with COVID-19 exhibited hyper-inflammatory signatures across all types of cells among PBMCs, particularly upregulation of the TNF/IL-1beta-driven inflammatory response as compared to severe influenza. In classical monocytes from patients with severe COVID-19, type I IFN response co-existed with the TNF/IL-1beta-driven inflammation, and this was not seen in patients with milder COVID-19 infection. Based on this, we propose that the type I IFN response exacerbates inflammation in patients with severe COVID-19 infection.

Project description:Hepatitis C virus (HCV) remains a significant public health threat as new 1.75 million HCV infections emerged worldwide. The majority of these infections become persistently infected, while around 30 % spontaneously eliminate the virus. Clinical factors for viral clarification are related to HCV interaction with host immune system, but little is known about the consequences after HCV spontaneous resolution. These individuals are difficult to recruit and study as acute infection is usually asymptomatic, and they will not be identified unless it progress to chronic infection. The study of peripheral blood mononuclear cells (PBMCs) of these patients is crucial, as PBMCs are one of the main HCV extrahepatic reservoirs, and its transcriptional profile provide us information of innate and adaptive immune response against HCV infection. Our research shows novel insight on molecular consequences of spontaneous resolution after an acute HCV infection. 96 Individuals with different HCV exposure status were recruited: spontaneous resolved, chronic infected and healthy controls; and the microRNA profile of their PBMCs were analyzed. Our results indicate similar disruption of miRNA expression on HCV chronic patients and those who spontaneously clarified the infection, compared to control patients. The disrupted miRNAs formed a signature of 21 miRNAs that mainly regulate lipid metabolism. This is the first report showing miRNA profile similarities between chronic HCV patients and spontaneous resolved individuals. Thus, our results suggest that HCV infection promotes molecular alterations in PBMCs that will last longer after HCV spontaneous eradication. This evidences open up new prospects in the management of individuals who spontaneously clarified infection, as they should be monitored and followed to dismiss future HCV-related complications, such us liver diseases complications. The identified miRNA signature could be used as biomarker to monitor HCV fingerprint on HCV-exposed patients.

Project description:IRF7 plays a critical role in the production and amplification of the antiviral type I and III interferon response. Autosomal recessive IRF7-deficiency resulted in life-threatening influenza disease in a 3-year-old child. We studied the impact of IRF7-deficiency in non-hematopoietic tissues (fibroblasts and lung epithelial cells) as well in hematopoietic cells (peripheral blood mononuclear cells (PBMCs)). Genome-wide gene expression analysis demonstrated a profound loss of type I and III IFNs in PBMCs infected with influenza virus. PBMCs were isolated from 4 healthy donors and patients with deficiencies for IRF7 and UNC93B. The cells were infected with influenza virus A/CA/4/2009 at a multiplicity of infection (MOI) of 2 for 8 and 16 hours. Uninfected cells were cultured for 16 hours.
