The hypothesis that SARS-Cov2 enables anaerobic bacteria to colonize the lungs disrupting homeostasis, causing long-drawn chronic symptoms, and acute severe symptoms (ARDS, septic shock, clots, arterial stroke) which finds resonance, with key differences, in the ‘forgotten disease’ Lemierre Syndrome [1], enabled by Epstein Barr Virus [2] has found corroboration in other studies. An assessment of immunity in mild versus severe COVID-19 infection in humans found that severity correlated with increased bacterial products in plasma [3], while another study reported endotoxemia and circulating bacteriome in severe COVID-19 patients [4]. Fusobacterium nucleatum bacteremia was reported in Covid19 patients in Belgium [5]. The overlapping symptoms can often confuse diagnosis [6, 7]. ‘Jugular vein distention’ should have led to a Lemierre like diagnosis [8]. While, these are commensal lung microbiome, hospital acquired infections (HAI) also play a major role in fatal outcomes for Covid19 patients. Acinetobacter/Legionella/Mycoplasma/Klebsiella possible co-infections in Covid19 patients from Russia (Accid:PRJNA682735). Some of these samples have no SARS-Cov2 reads - these could be control samples. The viral load is quite low in many patients, indicating that these might lead to false negative results [9]. It is interesting to note that samples with higher viral load also have higher % of anaerobic bacteria.

<li><strong>Increased air pollution exposure among the Chinese population during the national quarantine in 2020</strong> -
|

The COVID-19 quarantine in China is thought to have been beneficial for reducing the population exposure to ambient air pollution. The overall exposure also depends, however, on indoor air quality and human mobility and activities, which also changed during the pandemic. Here we integrate real-time mobility data, questionnaire survey on during-pandemic human activity patterns, advanced air quality modeling techniques, and an indoor exposure model. We first show a decrease of 16.7 μg∙m-3 in the national average population-weighted ambient PM2.5 during the quarantine (i.e., the one month following the start of the Spring Festival holiday). The total population-weighted exposure (PWE) to PM2.5 considering both indoor and outdoor environments, however, increased by 5.7 μg∙m-3. The increase in PWE was mainly due to the nationwide population migration from urban to rural areas before the Spring Festival coupled with the freezing of the migration backward due to the quarantine (+10.8 μg∙m-3), which increased household energy consumption and the fraction of people exposed to rural household air pollution (HAP) indoors. The changes in PWE due to the quarantine were -14.0 and +19.2 ug∙m-3 among urban and rural populations, respectively, and ranged from -9.1 ug∙m-3 in the provinces with the highest per-capita income to 7.1 ug∙m-3 in the provinces with the lowest. HAP contributed 82% of PWE during this period, which was likely more severe than any period in recent years. Our analysis reveals an increased inequality of air pollution exposure during the COVID-19 quarantine and highlights the importance of HAP for population health in China.

<li><strong>Evidence For COVID-19 Vaccine Deferred Dose 2 Boost Timing</strong> -
|
|||
|
|
<div>
|
|||
|
|
Both Pfizer and Moderna vaccine trials used accelerated methods to achieve rapid FDA approval with minimal and wise compromises. While many established vaccines use boost / dose 2 timings that are typically in the 3 to 120 months range , dose 2 timings for both trials were less than 30 days as part of a crucial effort to rapidly develop a vaccine with significant efficacy. Data from both trials showed excellent dose 1 efficacy; however, neither of the related Safety and Efficacy publications highlighted this dose 1 efficacy excellence. The trials, manufacturing, and distribution programs have rapidly delivered millions of doses to points of care. However, the ability to administer these doses at localities as rapidly as they can be distributed has been shown as the largest current challenge to achieving the widespread vaccination. Improvements could reduce mortality rates that presently exceed 2000 per day, avoid serious cases at a time where hospital census is at full capacity or beyond, and minimize long-term sequelae. This study suggests that it is possible to achieve these and other goals by recognizing the evidence for COVID-19 vaccine deferred boost timing and using a more conventional, decades-tested, boost timing on the order of months. This would enable currently limited US resources to effectively double the population being vaccinated over the next few months, enabling more rapid vaccination of those at highest-risk for severe infections.

The ability of S-glycoprotein (S-protein) in SARS-Cov-2 to bind to the host cell receptor protein (angiotensinconverting enzyme 2 (ACE2)) leading to its entry in cellular system determines its contagious index and global spread. Three available drugs (Riboflavin, Amodiaquin dihydrochloride dihydrate (ADD) and Remidesivir) were investigated to understand the kinetics of S-protein and its entry inside a cellular environment. Optical microscopy and fluorescence-based assays on 293T cells (transfected with ACE2 plasmid) were used as the preamble for assessing the behaviour of S-protein in the presence of these drugs for the first 12 hours post S-protein - ACE2 binding. Preliminary results suggest relatively long retention of S-protein on the cell membrane in the presence of ADD drug. Evident from the %-overlap and colocalization of S-protein with endosome studies, a large fraction of S-protein entering the cell escape endosomal degradation process, suggesting S-protein takes non-endocytic mediated entry in the presence of ADD, whereas in the presence of Riboflavin, S-protein carry out normal endocytic pathway, comparable to control (no drug) group. Therefore, present study indicates ADD potentially affects S-protein's entry mechanism (endocytic pathway) in addition to its reported target action mechanism. Hence, ADD substantially interfere with S-protein cellular entrance mechanism. However, further detailed studies at molecular scale will clarify our understanding of exact intermediate molecular processes. The present study (based on limited data) reveal ADD could be potential candidate to manage Covid-19 functions through yet unknown molecular mechanism.

<li><strong>Molecular Mechanism of the N501Y Mutation for Enhanced Binding between SARS-CoV-2's Spike Protein and Human ACE2 Receptor</strong> -
|

|
|
Coronavirus disease 2019 (COVID-19) has been an ongoing global pandemic for over one year. Recently, an emergent SARS-CoV-2 variant (B.1.1.7) with an unusually large number of mutations had become highly contagious and wide-spreading in United Kingdom. From genome analysis, the N501Y mutation within the receptor binding domain (RBD) of the SARS-CoV-2's spike protein might have enhanced the viral protein's binding with the human angiotensin converting enzyme 2 (hACE2). The latter is the prelude for the virus' entry into host cells. So far, the molecular mechanism of this enhanced binding is still elusive, which prevents us from assessing its effects on existing therapeutic antibodies. Using all atom molecular dynamics simulations, we demonstrated that Y501 in mutated RBD can be well coordinated by Y41 and K353 in hACE2 through hydrophobic interactions, increasing the overall binding affinity between RBD and hACE2 by about 0.81 kcal/mol. We further explored how the N501Y mutation might affect the binding between a neutralizing antibody (CB6) and RBD. We expect that our work can help researchers design proper measures responding to this urgent virus mutation, such as adding a modified/new neutralizing antibody specifically targeting at this variant in the therapeutic antibody cocktail.

In order to produce proteins essential for their propagation, many pathogenic human viruses, including SARS-CoV-2 the causative agent of COVID-19 respiratory disease, commandeer host biosynthetic machineries and mechanisms. Three major structural proteins, the spike, envelope and membrane proteins, are amongst several SARS-CoV-2 components synthesised at the endoplasmic reticulum (ER) of infected human cells prior to the assembly of new viral particles. Hence, the inhibition of membrane protein synthesis at the ER is an attractive strategy for reducing the pathogenicity of SARS-CoV-2 and other obligate viral pathogens. Using an in vitro system, we demonstrate that the small molecule inhibitor ipomoeassin F (Ipom-F) potently blocks the Sec61-mediated ER membrane translocation/insertion of three therapeutic protein targets for SARS-CoV-2 infection; the viral spike and ORF8 proteins together with angiotensin-converting enzyme 2, the host cell plasma membrane receptor. Our findings highlight the potential for using ER protein translocation inhibitors such as Ipom-F as host-targeting, broad-spectrum, antiviral agents.

Protection against SARS-CoV-2 and SARS-related emergent zoonotic coronaviruses is urgently needed. We made homotypic nanoparticles displaying the receptor-binding domain (RBD) of SARS-CoV-2 or co-displaying SARS-CoV-2 RBD along with RBDs from animal betacoronaviruses that represent threats to humans (mosaic nanoparticles; 4-8 distinct RBDs). Mice immunized with RBD-nanoparticles, but not soluble antigen, elicited cross-reactive binding and neutralization responses. Mosaic-RBD-nanoparticles elicited antibodies with superior cross-reactive recognition of heterologous RBDs compared to sera from immunizations with homotypic SARS-CoV-2-RBD-nanoparticles or COVID-19 convalescent human plasmas. Moreover, sera from mosaic-RBD-immunized mice neutralized heterologous pseudotyped coronaviruses equivalently or better after priming than sera from homotypic SARS-CoV-2-RBD-nanoparticle immunizations, demonstrating no immunogenicity loss against particular RBDs resulting from co-display. A single immunization with mosaic-RBD-nanoparticles provides a potential strategy to simultaneously protect against SARS-CoV-2 and emerging zoonotic coronaviruses.

SARS-CoV-2 entry in human cells is mediated by the interaction between the viral Spike protein and the human ACE2 receptor. This mechanism evolved from the ancestor bat coronavirus and is currently one of the main targets for antiviral strategies. However, there currently exist several Spike protein variants in the SARS-CoV-2 population as the result of mutations, and it is unclear if these variants may exert a specific effect on the affinity with ACE2 which, in turn, is also characterized by multiple alleles in the human population. In the current study, the GBPM analysis, originally developed for highlighting host-guest interaction features, has been applied to define the key amino acids responsible for the Spike/ACE2 molecular recognition, using four different crystallographic structures. Then, we intersected these structural results with the current mutational status, based on more than 295,000 sequenced cases, in the SARS-CoV-2 population. We identified several Spike mutations interacting with ACE2 and mutated in at least 20 distinct patients: S477N, N439K, N501Y, Y453F, E484K, K417N, S477I and G476S. Among these, mutation N501Y in particular is one of the events characterizing SARS-CoV-2 lineage B.1.1.7, which has recently risen in frequency in Europe. We also identified five ACE2 rare variants that may affect interaction with Spike and susceptibility to infection: S19P, E37K, M82I, E329G and G352V.

Here, we demonstrate that our anti-sepsis and COVID-19 drug candidate Rejuveinix (RJX) substantially improves the survival outcome in the LPS-GalN animal model of sepsis and multi-organ failure. One hundred (100) percent (%) of untreated control mice remained alive throughout the experiment. By comparison, 100% of LPS-GalN injected mice died at a median of 4.6 hours. In contrast to the invariably fatal treatment outcome of vehicle-treated control mice, 40% of mice treated with RJX (n=25) remained alive with a 2.4-fold longer median time survival time of 10.9 hours (Log-rank X2=20.60, P<0.0001). Notably, RJX increased the tissue levels of antioxidant enzymes SOD, CAT, and GSH-Px, and reduced oxidative stress in the brain. These findings demonstrate the clinical impact potential of RJX as a neuroprotective COVID-19 and sepsis drug candidate.

COVID-19 currently represents a major public health problem. Multiple efforts are being performed to control this disease. Vaccinations are already in progress. However, no effective treatments have been found so far. The disease is caused by the SARS-CoV-2 coronavirus that through the Spike protein interacts with its cell surface receptor ACE2 to enter into the host cells. Therefore, compounds able to block this interaction may help to stop disease progression. In this study, we have analyzed the effect of compounds reported to interact and modify the activity of ACE2 on the binding of the Spike protein. Among the compounds tested, we found that hydroxyzine could inhibit the binding of the receptor-binding domain of Spike protein to ACE2 in a qualitative in vitro assay. This finding supports the reported clinical data showing the benefits of hydroxyzine on COVID-19 patients, raising the need for further investigation into its effectiveness in the treatment of COVID-19 given its well-characterized medical properties and affordable cost.

The SARS-CoV-2 pandemic has affected more than 70 million people worldwide and resulted in over 1.5 million deaths. A broad deployment of effective immunization campaigns to achieve population immunity at global scale will depend on the biological and logistical attributes of the vaccine. Here, two adeno-associated viral (AAV)-based vaccine candidates demonstrate potent immunogenicity in mouse and nonhuman primates following a single injection. Peak neutralizing antibody titers remain sustained at 5 months and are complemented by functional memory T-cells responses. The AAVrh32.33 capsid of the AAVCOVID vaccine is an engineered AAV to which no relevant pre-existing immunity exists in humans. Moreover, the vaccine is stable at room temperature for at least one month and is produced at high yields using established commercial manufacturing processes in the gene therapy industry. Thus, this methodology holds as a very promising single dose, thermostable vaccine platform well-suited to address emerging pathogens on a global scale.

The majority of crystal structures are determined by the method of molecular replacement (MR). The range of application of MR is limited mainly by the need for an accurate search model. In most cases, pre-existing experimentally determined structures are used as search models. In favorable cases, ab initio predicted structures have yielded search models adequate for molecular replacement. The ORF8 protein of SARS-CoV-2 represents a challenging case for MR using an ab initio prediction because ORF8 has an all beta-sheet fold and few orthologs. We previously determined experimentally the structure of ORF8 using the single anomalous dispersion (SAD) phasing method, having been unable to find an MR solution to the crystallographic phase problem. Following a report of an accurate prediction of the ORF8 structure, we assessed whether the predicted model would have succeeded as an MR search model. A phase problem solution was found, and the resulting structure was refined, yielding structural parameters equivalent to the original experimental solution.

The SARS-Coronavirus-2 (SARS-CoV-2) infects cells through interaction of its spike protein (SARS2-S) with the ACE2 receptor and activation by proteases, in particular TMPRSS2. Viruses can also spread through fusion of infected with uninfected cells. We compared the requirements of ACE2 expression, proteolytic activation, and the sensitivity to inhibitors for SARS2-S-mediated and SARS1-S-mediated cell-cell fusion. SARS2-S-driven fusion was moderately increased by TMPRSS2 and strongly by ACE2, while SARS1-S-driven fusion was strongly dependent on activation by TMPRSS2 and less so on ACE2 expression. In contrast to SARS1-S, SARS2-S-mediated cell-cell fusion was efficiently activated by Batimastat-sensitive metalloproteases. Mutation of the S1/S2 proteolytic cleavage site reduced effector-target-cell fusion when ACE2 or TMPRSS2 were limiting and rendered SARS2-S-driven cell-cell fusion more dependent on TMPRSS2. When both ACE2 and TMPRSS2 were abundant, initial target-effector-cell fusion was unaltered compared to wt SARS2-S, but syncytia remained smaller over time. Mutation of the S2' site specifically abrogated activation by TMPRSS2 for both cell-cell fusion and SARS2-S-driven pseudoparticle entry but still allowed for activation by metalloproteases for cell-cell fusion and by cathepsins for particle entry. Finally, we found that the TMPRSS2 inhibitor Bromhexine was unable to reduce TMPRSS2-activated cell-cell fusion by SARS1-S and SARS2-S as opposed to the inhibitor Camostat. Paradoxically, Bromhexine enhanced cell-cell fusion in the presence of TMPRSS2, while its main metabolite Ambroxol exhibited weak inhibitory activity in some conditions. On Calu-3 lung cells, Ambroxol weakly inhibited SARS2-S-driven lentiviral pseudoparticle entry, and both substances exhibited a dose-dependent trend towards weak inhibition of authentic SARS-CoV-2.

Coinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other viruses is inevitable as the COVID-19 pandemic continues. This study aimed to evaluate cell lines commonly used in virus diagnosis and isolation for their susceptibility to SARS-CoV-2. While multiple kidney cell lines from monkeys were susceptible and permissive to SARS-CoV-2, many cell types derived from human, dog, mink, cat, mouse, or chicken were not. Analysis of MDCK cells, which are most commonly used for surveillance and study of influenza viruses, demonstrated that they were insusceptible to SARS-CoV-2 and that the cellular barrier to productive infection was due to low expression level of the angiotensin converting enzyme 2 (ACE2) receptor and lower receptor affinity to SARS-CoV-2 spike, which could be overcome by over-expression of canine ACE2 in trans. Moreover, SARS-CoV-2 cell tropism did not appear to be affected by a D614G mutation in the spike protein.

However, most existing antivirals have failed to cure COVID-19. Accordingly, there is an urgent need for new therapeutics with powerful antiviral and tolerable side effects. Here, we observed that recombinant human interferon-alpha (IFNa) triggered cell intrinsic and extrinsic antiviral responses and reduced replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in human lung epithelial Calu-3 cells. However, IFNa alone was insufficient to completely abolish SARS-CoV-2 replication. The combinations of IFNa with camostat, remdesivir, EIDD-2801, cycloheximide or convalescent serum showed strong synergy and, therefore, effectively inhibited SARS-CoV-2 infection. Additionally, we demonstrated synergistic antiviral activity of IFNa2a with pimodivir against influenza A virus (FluAV) infection in human lung epithelial A549 cells, as well as IFNa2a with lamivudine against human immunodeficiency virus 1 (HIV-1) infection in human TZM-bl cells. Our results indicate that IFNa2a-based combinational therapies help to reduce drug dose and improve efficacy in comparison with monotherapies, making them attractive targets for further pre-clinical and clinical development. Additionally, they have powerful treatment potential, and can be leveraged for use in the inhibition of not only emerging or re-emerging viruses, but also immune-evading or drug-resistant viral variants, and viral co-infections.
