    Human cells respond to infection by SARS-CoV-2, the virus that causes COVID-19 MESHD, by producing cytokines including type I and III interferons (IFNs) and proinflammatory factors such as IL6 HGNC and TNF HGNC. IFNs can limit SARS-CoV-2 replication but cytokine imbalance contributes to severe COVID-19 MESHD. We studied how cells detect SARS-CoV-2 infection MESHD. We report that the cytosolic RNA sensor MDA5 HGNC was required for type I and III IFN induction in the lung cancer MESHD cell line Calu-3 upon SARS-CoV-2 infection MESHD. Type I and III IFN HGNC induction further required MAVS HGNC and IRF3 HGNC. In contrast, induction of IL6 HGNC and TNF HGNC was independent of the MDA5 HGNC- MAVS HGNC- IRF3 HGNC axis in this setting. We further found that SARS-CoV-2 infection MESHD inhibited the ability of cells to respond to IFNs. In sum, we identified MDA5 HGNC as a cellular sensor for SARS-CoV-2 infection MESHD that induced type I MESHD and III IFNs.

    Following entry and replication of Severe Acute Respiratory Syndrome-coronavirus MESHD 2 (SARS-CoV-2) into ACE2 expressing cells, the infected cells undergo lysis releasing more virus but also cell contents. In the lung, constitutive cytokines such as IL-1 HGNC are released together with other cell contents. A cascade of inflammatory cytokines ensues, including chemokines and IL-1{beta}, triggering both local as well as systemic inflammation MESHD. This cascade of inflammatory cytokines in patients with COVID-19 MESHD is termed Cytokine Release Syndrome ( CRS MESHD), and is associated with poor outcomes and death MESHD. Many studies reveal that blocking IL-1{beta HGNC} activities in COVID-19 MESHD patients reduces disease severity and deaths MESHD. Here we report highly significant circulating levels of IL-1{beta HGNC}, IL-1 Receptor antagonist HGNC, IL-6 HGNC, TNF HGNC, IL-10 HGNC and soluble urokinase plasminogen activator receptor HGNC in COVID-19 MESHD patients with mild or no symptoms. We also report that in circulating myeloid cells from the same patients, there is increased expression of the NOD-, LRR- and pyrin domain-containing 3 ( NLRP3 HGNC) early in the infection. We observed increased NLRP3 HGNC gene expression in myeloid cells correlated with IL-1{beta HGNC} gene expression and also with elevated circulating IL-1{beta HGNC} levels. We conclude that early in SARS-CoV-2 infection MESHD, NLRP3 HGNC activation takes place and initiates the CRS. Thus, NLRP3 HGNC is a target to reduce the organ damage of inflammatory cytokines of the CRS.

    SARS-CoV-2 infection MESHD causes cytokine storm and overshoot immunity in humans; however, it remains to be determined whether genetic material of SARS-CoV-2 and/or virus induced soluble mediators from lung epithelial cells as natural host are carried out by macrophages or other vehicles at distant organs causing tissue damage. We speculated that exosomes as extracellular vesicles are secreted from SARS-CoV-2 infected MESHD cells may transport messages to other cells of distant organs leading to pathogenic consequences. For this, we took an unbiased proteomic approach for analyses of exosomes isolated from plasma of healthy volunteers and SARS-CoV-2 infected MESHD patients. Our results revealed that tenascin-C HGNC ( TNC HGNC) and fibrinogen-{beta} ( FGB HGNC) are highly abundant in exosomes from SARS-CoV-2 infected MESHD patient's plasma as compared to that of healthy normal controls. Since TNC HGNC and FGB HGNC stimulate pro-inflammatory cytokines via NF-kB pathway, we examined the status of TNF-a HGNC, IL-6 HGNC and CCL5 HGNC expression upon exposure of hepatocytes to exosomes from COVID-19 MESHD patients and observed significant increase when compared with that from healthy subjects. Together, our results demonstrated that soluble mediators, like TNC HGNC and FGB HGNC, are transported through plasma exosomes in SARS-CoV-2 infected MESHD patients and trigger pro-inflammatory cytokine expression in cells of distant organs in COVID-19 MESHD patients.

    An understanding of the pathological inflammatory mechanisms involved in SARS CoV-2 virus infection MESHD is necessary in order to discover new molecular pharmacological targets for SARS-CoV-2 spike PROTEIN glycoprotein. In this study, the effects of a recombinant SARS CoV-2 spike PROTEIN glycoprotein S1 was investigated in human peripheral blood mononuclear cells (PBMCs). Stimulation with spike glycoprotein S1 PROTEIN (100 ng/mL) resulted in significant elevation in the production of TNF HGNC, IL-6 HGNC, IL-1{beta HGNC} and IL-8 HGNC. However, pre-treatment with dexamethasone (100 nM) caused a significant reduction in the release of these cytokines. Further experiments revealed that S1 stimulation of PBMCs increased phosphorylation of NF-{kappa}B HGNC p65 HGNC and I{kappa}B, while increasing I{kappa}B degradation. DNA binding of NF-{kappa}B HGNC p65 HGNC was also significantly increased following stimulation with S1. Treatment of PBMCs with dexamethasone (100 nM) or BAY11-7082 (1 M) resulted in inhibition of S1-induced NF-{kappa}B HGNC activation. Activation of p38 HGNC MAPK by S1 was blocked in the presence of dexamethasone and SKF 86002. CRID3, but not dexamethasone pre-treatment produced significant inhibition of S1-induced activation of NLRP3 HGNC/ caspase 1 HGNC. Further experiments revealed that S1-induced increase in the production of TNF HGNC, IL-6 HGNC, IL-1{beta HGNC} and IL-8 HGNC was reduced in the presence of BAY11-7082 and SKF 86002, while CRID3 pre-treatment resulted in the reduction of IL-1{beta HGNC} production. These results suggest that SARS-CoV-2 spike PROTEIN glycoprotein S1 stimulate PBMCs to release pro inflammatory cytokines through mechanisms involving activation of NF-{kappa}B HGNC, p38 MAPK and NLRP3 HGNC inflammasome. It is proposed that clinical benefits of dexamethasone in COVID-19 MESHD is possibly due to its anti-inflammatory activity in reducing SARS-CoV-2 cytokine storm.

    In a study of 207 SARS-CoV2-infected MESHD individuals with a range of severities followed over 12 weeks from symptom onset, we demonstrate that an early robust immune response, without systemic inflammation MESHD, is characteristic of asymptomatic or mild disease. Those presenting to hospital had delayed adaptive responses and systemic inflammation MESHD already evident at around symptom onset. Such early evidence of inflammation MESHD suggests immunopathology may be inevitable in some individuals, or that preventative intervention might be needed before symptom onset. Viral load does not correlate with the development of this pathological response, but does with its subsequent severity. Immune recovery is complex, with profound persistent cellular abnormalities correlating with a change in the nature of the inflammatory response, where signatures characteristic of increased oxidative phosphorylation and reactive-oxygen species-associated inflammation MESHD replace those driven by TNF HGNC and IL-6 HGNC. These late immunometabolic inflammatory changes and unresolved immune cell defects, if persistent, may contribute to "long COVID".

    BACKGROUND. Neurological complications MESHD occur in COVID-19 MESHD. We aimed to examine cerebrospinal fluid (CSF) of COVID-19 MESHD subjects with neurological complications MESHD and determine presence of neuroinflammatory changes implicated in pathogenesis. METHODS. Cross-sectional study of CSF neuroinflammatory profiles from 18 COVID-19 MESHD subjects with neurological complications categorized by diagnosis ( stroke MESHD, encephalopathy MESHD, headache MESHD) and illness severity (critical, severe, moderate, mild). COVID-19 MESHD CSF was compared with CSF from healthy, infectious and neuroinflammatory disorders MESHD and stroke MESHD controls (n=82). Cytokines ( IL-6 HGNC, TNF-alpha HGNC, IFN-gamma HGNC, IL-10 HGNC, IL-12p70, IL-17A HGNC), inflammation MESHD and coagulation markers (high-sensitivity- C Reactive Protein HGNC [hsCRP], ferritin, fibrinogen HGNC, D-dimer, Factor VIII) and neurofilament light chain ( NF-L HGNC), were quantified. SARS-CoV2 RNA and SARS-CoV2 IgG and IgA antibodies in CSF were tested with RT-PCR and ELISA. RESULTS. CSF from COVID-19 MESHD subjects showed a paucity of neuroinflammatory changes, absence of pleocytosis MESHD or specific increases in pro-inflammatory markers or cytokines ( IL-6 HGNC, ferritin, or D-dimer). Anti-SARS-CoV2 antibodies in CSF of COVID-19 MESHD subjects (77%) were observed despite no evidence of SARS-CoV2 viral RNA. A similar increase of pro-inflammatory cytokines ( IL-6 HGNC, TNF-alpha HGNC;, IL-12p70) and IL-10 HGNC in CSF of COVID-19 MESHD and non- COVID-19 MESHD stroke MESHD subjects was observed compared to controls. CSF-NF-L was elevated in subjects with stroke MESHD and critical COVID-19 MESHD. CSF-hsCRP was present almost exclusively in COVID-19 MESHD cases. CONCLUSION. The paucity of neuroinflammatory changes in CSF of COVID-19 MESHD subjects and lack of SARS-CoV2 RNA do not support the presumed neurovirulence of SARS-CoV2 or neuroinflammation MESHD in pathogenesis of neurological complications in COVID-19 MESHD. Elevated CSF-NF-L indicates neuroaxonal injury MESHD in COVID-19 MESHD cases. The role of CSF SARS-CoV2 IgG antibodies is still undetermined.

    The emergence of SARS-CoV-2 has resulted in a global pandemic. In addition to respiratory complications as a result of SARS-CoV-2 illness MESHD, accumulating evidence suggests that neurological and neuropsychiatric symptoms MESHD are associated with the disease caused by the virus. In this study, we investigated the effects of the SARS-CoV-2 spike PROTEIN glycoprotein S1 stimulation on neuroinflammation in BV-2 microglia. Analyses of culture supernatants revealed an increase in the production of TNF HGNC, IL-6 HGNC, IL-1{beta HGNC} and iNOS HGNC/NO. SARS-CoV-2 spike PROTEIN glycoprotein S1 increased protein expressions of phospho-p65 and phospho-I{kappa}B, as well as enhancing DNA binding and transcriptional activity of NF-{kappa}B HGNC. Pro-inflammatory effects of the glycoprotein effects were reduced in the presence of BAY11-7082 (1 M). The presence of SARS-CoV-2 spike PROTEIN glycoprotein S1 in BV-2 microglia increased the protein expression of NLRP3 HGNC, as well as caspase-1 HGNC activity. However, pre-treatment with CRID3 (1 M) or BAY11-7082 (1 M) resulted in the inhibition of NLRP3 HGNC inflammasome/ caspase-1 HGNC. It was also observed that CRID3 attenuated SARS-CoV-2 spike PROTEIN glycoprotein S1-induced increase in IL-1{beta HGNC} production. Increased protein expression of p38 MAPK was observed in BV-2 microglia stimulated with the spike glycoprotein S1 PROTEIN, and was reduced in the presence of SKF 86002. These results have provided the first evidence demonstrating SARS-CoV-2 spike PROTEIN S1 glycoprotein-induced neuroinflammation in BV-2 microglia. We propose that promotion of neuroinflammation by this glycoprotein is mediated through activation of NF-{kappa}B HGNC, NLRP3 HGNC inflammasome and p38 MAPK. These results are significant because of their relevance to our understanding of neurological and neuropsychiatric symptoms MESHD observed in patients infected with SARS-CoV-2.

    The efficacy of virus-specific T cells in clearing pathogens involves a fine balance between their antiviral and inflammatory features. SARS-CoV-2-specific T cells in individuals who clear SARS-CoV-2 infection MESHD without symptoms or disease could reveal non-pathological yet protective characteristics. We therefore compared the quantity and function of SARS-CoV-2-specific T cells in a cohort of asymptomatic individuals (n=85) with that of symptomatic COVID-19 MESHD patients (n=76), at different time points after antibody seroconversion. We quantified T cells reactive to structural proteins (M PROTEIN, NP and Spike) using ELISpot assays, and measured the magnitude of cytokine secretion ( IL-2 HGNC, IFN-{gamma HGNC}, IL-4 HGNC, IL-6 HGNC, IL-1{beta}, TNF- and IL-10) in whole blood following T cell activation with SARS-CoV-2 peptide pools as a functional readout. Frequencies of T cells specific for the different SARS-CoV-2 proteins in the early phases of recovery were similar between asymptomatic and symptomatic individuals. However, we detected an increased IFN-{gamma HGNC} and IL-2 HGNC production in asymptomatic compared to symptomatic individuals after activation of SARS-CoV-2-specific T cells in blood. This was associated with a proportional secretion of IL-10 HGNC and pro-inflammatory cytokines ( IL-6 HGNC, TNF HGNC- and IL-1{beta} HGNC) only in asymptomatic infection, while a disproportionate secretion of inflammatory cytokines was triggered by SARS-CoV-2-specific T cell activation in symptomatic individuals. Thus, asymptomatic SARS-CoV-2 infected MESHD individuals are not characterized by a weak antiviral immunity; on the contrary, they mount a robust and highly functional virus-specific cellular immune response. Their ability to induce a proportionate production of IL-10 HGNC might help to reduce inflammatory events during viral clearance.

    IMPORTANCE: Recent studies positing the gut as a sanctuary site for viral persistence in SARS-CoV-2 infection MESHD highlight the importance of assimilating profiles of systemic as well as gut inflammatory mediators to understand the pathology of COVID-19 MESHD. Also, the role of these markers in governing virus specific immunity following infection remains largely unexplored. OBJECTIVE: To evaluate the role of systemic and gut inflammatory markers in disease progression and development of anti-viral humoral immunity following SARS-CoV-2 infection MESHD. DESIGN, SETTING AND PARTICIPANTS: This cohort study (n=58) of SARS-CoV-2 infected MESHD individuals included a group of in-patients (n=36) at various stages of disease progression together with convalescent individuals (n=22) recruited between April and June 2020 (peak of the epidemic) from a tertiary care hospital in Mumbai, India. Follow-up of 11 in-patients at day 7 post diagnosis was carried out, resulting in a total of 47 in-patient samples. EXPOSURES: Diagnosis of SARS-CoV-2 infections MESHD was confirmed by reverse transcriptase-polymerase chain reaction-based testing of nasopharyngeal/oropharyngeal samples. MAIN OUTCOMES AND MEASURES: Primary outcomes were the measurement of inflammatory markers including Th1 HGNC/Th2/Th17 cytokines and levels of soluble mucosal addressin cell adhesion molecule (sMAdCAM) in plasma. Anti-viral humoral response was measured by rapid antibody test (IgG, IgM) and chemiluminescent immunoassay (CLIA) (IgG). Also antibodies binding to SARS-CoV-2 proteins were measured by surface plasmon resonance ( SPR HGNC). Secondary outcomes were correlation of the inflammatory signature with clinical information, including age, sex, disease duration and co-morbidities. RESULTS: Twenty eight of 36 (78%) in-patients and 19 of 22 (86%) convalescents were males. Out of 47 in-patient samples, 22 (46%), 11 (23%) and 14 (30%) were IgG-/IgM-, IgG+/IgM+ and IgG+/IgM- respectively. Of 22 convalescent samples, 3 (14%), 1 (4%) and 17 (77%) were respectively IgG-/IgM-, IgG+/IgM+ and IgG+/IgM-. Two out of 22 (9%) convalescents showed high IL-6 HGNC levels (>100pg/ml) and 4 (18%) had high TNF HGNC levels (>30pg/ml). However, the convalescents (n =22) had significantly lower levels of IL-6 HGNC [Median=27.48 (IQR=23.54-39.92)] compared to followed up in-patients (n = 11) at day 0 [Median=111(IQR=68-129.7), p =0.0002] and higher levels of sMAdCAM [Median=1940 (1711-2174) pg/ml] compared to these individuals at day 0 [Median=1701 (IQR=1532-1836) pg/ml; p=0.032] and day 7 [Median=1534 (IQR=1236-1654) pg/ml; p=0.0007]. Further, IL-6 HGNC and sMAdCAM levels among in-patients inversely correlated with one another (r =-0.374, p = 0.009, CI = 95%). When expressed as a novel integrated marker, sMIL (sMAdCAM/ IL-6 HGNC ratio) index, these levels were incrementally and significantly higher across various disease states with convalescents exhibiting the highest values [Median= 64.74 (IQR=47.33-85.58)]. Also, the sMIL index was significantly higher in convalescents (with class-switched responses) compared to IgG+/IgM+ individuals at early stages of infection [Median=28.65 (IQR=13.63-96.26), p = 0.034]. Real-time measurement by SPR HGNC of plasma antibody binding to viral nucleocapsid (NC), receptor binding domain (RBD) and spike (S) revealed waxing and waning of plasma antibody responses to all 3 targets. Importantly, sMAdCAM levels as well as sMIL index (fold change) correlated with peak association rates of RBD-binding (r = 0.462, p = 0.03, CI = 95%) and fold change in binding to S (r = 0.68, p = 0.050, CI = 95%) respectively. CONCLUSION AND RELEVANCE: Our results highlight key systemic and gut-associated immune parameters that need to be monitored and investigated further to optimally guide therapeutic and prophylactic interventions for COVID-19 MESHD.

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection MESHD induces severe pneumonia MESHD and is the cause of a worldwide pandemic. Coronaviruses, including SARS-CoV-2, have RNA proofreading enzymes in their genomes, resulting in fewer gene mutations than other RNA viruses. Nevertheless, variants of SARS-CoV-2 exist and may induce different symptoms; however, the factors and the impacts of these mutations are not well understood. We found that there is a bias to the mutations occurring in SARS-CoV-2 variants, with disproportionate mutation to uracil (U). These point mutations to U are mainly derived from cytosine (C), which is consistent with the substrate specificity of host RNA editing enzymes, APOBECs. We also found the point mutations which are consistent with other RNA editing enzymes, ADARs. For the C-to-U mutations, the context of the upstream uracil and downstream guanine from mutated position was found to be most prevalent. Further, the degree of increase of U in SARS-CoV-2 variants correlates with enhanced production of cytokines, such as TNF-a HGNC and IL-6 HGNC, in cell lines when compared with stimulation by the ssRNA sequence of the isolated virus in Wuhan. Therefore, RNA editing is a factor for mutation bias in SARS-CoV-2 variants, which affects host inflammatory cytokines production.
