Project description:The present study for the first time described the features of children’s lung by scRNA-seq and compared the results to the data acquired from healthy adults (GSE122960). We analyzed the expression levels of viral-entry associated genes in both children and adults’ lung tissues by single cell RNA sequencing (scRNA-seq) to explore whether the expression levels of these genes might contribute to the milder symptoms in SARS-CoV-2 infected children. The results of scRNA-seq showed comparable expression of the key genes for SARS-CoV-2 entry in children and adults, including ACE2, TMPRSS2 and FURIN, suggesting that instead of lower virus intrusion rate, other factors are more likely to be the key reasons for the milder symptoms of SARS-CoV-2 infected children.

Project description:Asthma is multi-factorial disorder, and microbial dysbiosis enhances lung inflammation and asthma-related symptoms. Probiotics has shown anti-inflammatory effect and could regulate the gut-lung axis. Thus, a three-month randomized, double-blind, and placebo-controlled human trial was performed to investigate the adjunctive efficacy of probiotics in managing asthma.

Project description:Background: Intestinal failure-associated liver disease (IFALD) is a common complication of long-term parenteral nutrition (PN) that is associated with significant morbidity and mortality. Ferroptosis, as an iron-dependent regulated cell death, has been shown to play an important role in the development of several liver diseases. This study focuses on investigating whether the ferroptosis phenomenon is present in TPN-induced IFALD and further exploring the potential regulatory mechanisms. Methods: Ferroptosis hallmarkers were measured in children with short bowel syndrome (SBS) who had long-term PN use and caused IFALD. Sprague-Dawley (SD) rats were used to establish a rat model of IFALD with a concomitant ferroptosis inhibition intervention using liproxstain-1. The mir-431 lineage was identified as a potential upstream regulatory mir-RNA by mir-RNA sequencing. HepG2 and 293T cell line was used to demonstrate that mir-431 regulates ferroptosis through the GPX4 pathway at the cellular level in vitro. Results: Ferroptosis is upregulated in liver of children with IFALD. Liproxstain-1 downregulates ferroptosis in a rat model of IFALD and attenuates hepatic steatosis through the lipid metabolism pathway. In vitro HepG2 and 293T cell experiments reveal that mir-431 affects ferroptosis by regulating GPX4 protein. Conclusions: Ferroptosis plays an important role in the development of IFALD. Liproxstain-1 inhibits ferroptosis and attenuates hepatic steatosis in a rat model of IFALD through the lipid metabolism pathway. Mir-431 negatively regulates GPX4 protein-induced ferroptosis.

Project description:While fewer cases of severe Coronavirus Disease 2019 (COVID-19) are reported globally in children, a small proportion of SARS-CoV-2 infected children develop a novel pediatric febrile entity called multisystem inflammatory syndrome in children (MIS-C) that develops 2 to 5 weeks after initial SARS-CoV-2 exposure. MIS-C primarily effects male children and children of Hispanic or black descent. MIS-C manifests as a severe and uncontrolled inflammatory response with multiorgan involvement. A hyperinflammatory state is evidenced by clinical makers of inflammation including high levels of C-reactive protein (CRP), ferritin, and D-dimers, and an increased expression of pro-inflammatory cytokines. Children often present with persistent fever, severe gastrointestinal symptoms, cardiovascular manifestations, respiratory symptoms and neurological symptoms6-11,13. Cardiovascular manifestations include hypotension, shock, cardiac dysfunction, myocarditis and pericardial effusion. In the united states, admission to the intensive care unit occurs in approximately 58% of cases. To understand disease pathogenesis of MIS-C and proteins associated with the severe form of disease we performed proteomics analysis of serum or plasma samples. We collected serum from healthy children (SARS-CoV-2 negative, n=20), mild MIS-C (non-ICU, n=5) and severe MIS-C (ICU, n = 20) patients. MIS-C definition and diagnosis was performed according to CDC guidelines. Healthy adult serum (n = 4) was also used for reference ranges quality control and we obtained plasma samples from Kawasaki Disease (KD; n=7) patients that were recruited before the Coronavirus Disease 2019 (COVID-19) pandemic.

Project description:Background :To evaluate the impact of the duration of chronic inflammation on gene expression in skeletal muscle biopsies (MBx) from untreated children with juvenile dermatomyositis (JDM) and identify genes and biological processes associated with the disease progression, expression profiling data from 16 girls with active symptoms of JDM greater or equal to 2 months were compared with 3 girls with active symptoms less than 2 months. Results: Seventy-nine genes were differentially expressed between the groups with long or short duration of untreated disease. Genes involved in immune responses and vasculature remodeling were expressed at a higher level in muscle biopsies from children with greater or equal to 2 months of symptoms, while genes involved in stress responses and protein turnover were expressed at a lower level. Among the 79 genes, expression of 9 genes showed a significant linear regression relationship with the duration of untreated disease. Five differentially expressed genes--HLA-DQA1, smooth muscle myosin heavy chain, clustering, plexin D1 and tenomodulin--were verified by quantitative RT-PCR. The chronic inflammation of longer disease duration was also associated with increased DC-LAMP+ and BDCA2+ mature dendritic cells, identified by immunohistochemistry. Conclusions: We conclude that chronic inflammation alters the gene expression patterns in muscle of untreated children with JDM. Symptoms lasting greater or equal to 2 months were associated with dendritic cell maturation and anti-angiogenic vascular remodelling, directly contributing to disease pathophysiology.

Experiment Overall Design: After obtaining informed consent, 23 girls with definite JDM were enrolled in this study prior to obtaining the MRI directed diagnostic muscle biopsy. All 23 JDM samples and 4 healthy age- and sex-matched controls were expression profiled and for first gene filtering. Only profiling data from untreated patients (19 profiles) were then analyzed statistically.
