Project description:Human SARS-CoV-2 and avian IBV are highly contagious and deadly coronaviruses causing devastating respiratory diseases in human and chicken, respectively. Lacking effective therapies exacerbates the disease associated with SARS-CoV-2 and IBV infections. Thus, novel therapeutic agents are in demand for controlling viral transmission and disease progression. Mesenchymal stem cells secreted factors (secretome) proven to be safe and highly efficient alternative to stem cells in mesenchymal stem cell-based therapy (MSCT). The most favorable advantage of secretome is the bypass of the side effects of MSCT that include but not limited to tumorigenesis, immune rejection, and infection. In this study, we aimed to investigate the antiviral activities of human Wharton’s jelly mesenchymal stem cells secretome against SARS-CoV-2 and IBV infection. The half-maximal inhibitory concentrations (IC50), and cytotoxic concentration (CC50) values of hWJ-MSC secretome (hWJ-MSC-S) were determined in Vero-E6 cells. Virucidal, anti-adsorption, and anti-replication mechanisms of hWJ-MSC-S against SARS-CoV-2 and IBV infection were evaluated in vitro. In Ovo anti-IBV activity of hWJ-MSC-S was estimated using Specific pathogen-free (SPF) embryonated chicken eggs (ECEs). The antiviral efficacy of hWJ-MSC-S was determined in terms of reduction in viral infection. Protein composition of hWJ-MSC-S was analyzed by mass spectrometry analysis, and gene ontology of secretome proteins was evaluated. Our data showed hWJ-MSC-S to significantly inhibits infection of human SARS-CoV-2 and avian IBV with very low cytotoxicity and embryotoxicity profile. CC50 value of hWJ-MSC-S in Vero-E6 was 39200 µg/ml. IC50, SI values of hWJ-MSC secretome against SARS-CoV-2 were 166.6 µg/ml, and 235.29, respectively. Similarly, IC50, SI values of hWJ-MSC-S against IBV were 439.9 µg/ml, and 89.11, respectively. hWJ-MSC-S reduced PFU/ml of SARS-CoV-2 and IBV by > 90%. Antiviral mechanistic studies demonstrated that hWJ-MSC-S had >95% and >90% virucidal effects on SARS-CoV-2 and IBV infections, respectively. The anti-replication effect was approximately 87.33% against SARS-CoV-2 infection, and >90% against IBV infection. In ovo model, hWJ-MSC-S significantly inhibited IBV infection. At a concentration of 1000 µg/ml, hWJ-MSC-S reduced IBV titre from 763000 ± 32638 to 38.333 ± 6.0093 EID50/ml (>99% inhibition). Similarly, hWJ-MSC-S reduced IBV titer from 763000 ± 32638 to 1896 ± 926.1 EID50/ml (>97% inhibition) at a concentration of 500 µg/ml. In addition, 250 µg/ml concentration of hWJ-MSC-S reduce IBV titer from 763000 ± 32638 to 20380 ± 2885 EID50/ml (>96% inhibition). LC/MS-MS analysis revealed that biological processes of hWJ-MSC-S proteins were mostly related to Immunomodulatory effect. Collectively, our results not only uncovered the antiviral potency of hWJ-MSC-S against SARS-CoV-2 and IBV, but also described the mechanism by which hWJ-MSC-S inhibit viral infection. These findings could be utilized in future pre-clinical and clinical studies to develop an effective therapeutic against human COVID-19 and avian IB respiratory diseases using hWJ-MSC-S.

Project description:DEP exposure is linked to increases in cardiovascular effects. This effect is enhanced in individuals with pre-existing disease. Animal models of cardiovascular disease are used to study this susceptibility. The heart is rich in mitochondria, which produce high levels of free radicals, leading to inactivation of tricarboxylic acid cycle enzymes. We hypothesized that a 4-wk DEP inhalation would result in strain-related structural impairment of cardiac mitochondria and changes in these enzyme activities in WKY and SHR. Male rats (12-14 wks age) were exposed whole body to air or 0.5 or 2.0 mg/m3 DEP for 6h/d, 5 d/wk for 4 wks. Neutrophilic influx was noted in the bronchoalveolar lavage fluid in both strains. A slightly lower level of baseline cardiac mitochondrial aconitase activity was seen in SHR than WKY. Aconitase activity appeared to be decreased in an exposure related manner in both strains. Significantly higher baseline levels of cardiac cytosolic ferritin and aconitase activity were seen in the SHR than WKY. No exposure-related changes were noted in either of these measures. Mitochondrial succinate and isocitrate dehydrogenase activities were not changed following DEP exposure in either strain. Transmission electron microscopy images of the heart indicated abnormalities in cardiac mitochondria of control SHR but not control WKY. No exposure related ultrastructural changes were induced by DEP in either strain. In conclusion, strain differences in cardiac biomarkers of oxidative stress and structure of mitochondria exist between SHR and WKY. DEP exposure results in small changes in cardiac mitochondrial and cytosolic markers of oxidative stress. (Abstract does not represent USEPA policy.) Experiment Overall Design: Two strains of rats (Wistar Kyoto (WKY) and spontaneously hypertensive (SH) rats were exposed to either diesel exhaust particles or clean air. Four biological replicates were used for each strain/treatment exposure. Total number of chips equals 16.

Project description:Mesenchymal stem cells (MSCs) are generally considered the main tool box for cell-based therapies and compared to embryonic stem cells (ESCs), MSCs exhibit many advantages. It has been shown that UC matrix (the Wharton’s Jelly surrounding umbilical vessels) contains a great number of mesenchymal cells. The abundant amount of Wharton’s Jelly (WJ) makes it an attractive source of MSCs for cell-based therapies. recently have been highlighted the changes in protein expression profiling during in vitro expansion of WJ-MSC, probably related to the gradual reduction of their staminal plasticity and to the biological cellular mechanism occurring in the cellular aging. The aim of the present work was to analyze the transcriptomic profile useful to the definition of WJ-MSC characteristics and therefore identify possible different new marker candidates. In these contest, changes in gene expression profiles occurring during WJ-MSC in vitro growth wile by analyzed in order to find possible modulation related to their long expansion and fast growth abilities. We analyzed the changes in total RNA expression at the 12th in vitro expansion cycle compared to the 4th in vitro expansion cycle.

Project description:Association between air pollutants and inflammatory diseases such as Otitis Media (OM) has been shown in recent studies. Indeed, significantly higher rates of OM incidence in air polluted area have been evident by epidemiological researchers. Diesel exhaust particle (DEP), one of major components among diverse air pollutants, is characterized by a carbonic mixture composed of polycyclic aromatic hydrocarbons (PAHs), nitro-PAHs, small amounts of sulfate, nitrate, metals, and other trace elements. The exposure to DEP as a risk factor for inflammatory diseases has been reported in several recent investigations. In line with these, our previous study identified potential biomarkers in in vitro system through gene expression microarray and pathway analysis. Although investigations in in vitro system have been conducted to elucidate plausible biomarkers and molecular mechanisms related with DEP, it is necessary to carry out in vivo study to identify exact biological relevance regarding incidence of OM caused by DEP exposure. In this study, we discovered potential molecular biomarkers and pathways triggered by DEP exposure in rodent model. Here, we conducted transcriptomic analysis to identify novel potential biomarkers in middle ears of DEP-exposed mice. A total of 697 genes were differentially expressed in the DEP-exposed mice; 424 genes and 273 genes were up-and down-regulated, respectively. In addition, signaling pathways among differentially expressed genes mediated by DEP exposure were predicted from different two point of view. Subsequently, we identified several key molecular biomarkers, CHRM1, EPO, SOS1, ESR1, CD4, and IFNA1. In conclusion, our results might ascertain related cell process and signaling interacted genes underlying DEP exposure and its effects. Moreover, the discovered biomarkers can be recognized as potential candidates for developing early diagnosis and effective treatment strategies of DEP-mediated disorders.
