• Sexist Attitudes and Family Aggression during COVID-19 Lockdown -
  The current research examined whether men’s hostile sexism was a risk factor for family-based aggression during a nationwide COVID-19 lockdown in which families were confined to the home for 5 weeks. Parents who had reported on their sexist attitudes and aggressive behavior toward intimate partners and children prior to the COVID-19 pandemic completed assessments of aggressive behavior toward their partners and children during the lockdown (N = 362 parents of which 310 were drawn from the same family). Accounting for pre-lockdown levels of aggression, men who more strongly endorsed hostile sexism reported greater aggressive behavior toward their intimate partners and their children during the lockdown. The contextual factors that help explain these longitudinal associations differed across targets of family-based aggression. Men’s hostile sexism predicted greater aggression toward intimate partners when men experienced low power during couples’ interactions, whereas men’s hostile sexism predicted greater aggressive parenting when men reported lower partner-child relationship quality. Novel effects also emerged for benevolent sexism. Men’s higher benevolent sexism predicted lower aggressive parenting, and women’s higher benevolent sexism predicted greater aggressive behavior toward partners, irrespective of power and relationship quality. The current study provides the first longitudinal demonstration that men’s hostile sexism predicts residual changes in aggression toward both intimate partners and children. Such aggressive behavior will intensify the health, well-being, and developmental costs of the pandemic, highlighting the importance of targeting power-related gender role beliefs when screening for aggression risk and delivering therapeutic and education interventions as families face the unprecedented challenges of COVID-19.

• Pandemic Compliance: A systematic review of influences on social distancing behaviour during the first wave of the COVID-19 outbreak -
  During the first wave of the COVID-19 pandemic, mitigation measures compelling people to keep a safe social distance led to a massive, unprecedented behavioural change across the globe. The present study seeks to understand what variables made people comply with such mitigation measures. It systematically reviewed 45 studies with data about compliance behaviour during the first wave (found in searches from March 1st till June 30th 2020). The review shows that a combination of variables shaped compliance behaviour, including people’s fear of the virus, psychosocial factors (including impulsivity, negative emotions, self-efficacy, and social norms), institutional variables (including attitudes towards the mitigation measures, belief in conspiracy theories and knowledge of the virus), and situational variables (capacity to obey and opportunity to violate the rules). Notably, the reviewed studies did not find a significant association between law enforcement (perceived deterrence) and compliance here. The review assesses what these findings mean for behavioural theory and for policy makers seeking to mitigate pandemics like COVID-19. Also, it reflects on the limitations of the reviewed body of work and future directions for pandemic compliance research.

• Psychiatry and Covid-19: Acute mental health presentations before and during the pandemic -
  Background We aimed to analyse numbers and types of psychiatric presentations to inform planning for future demand on mental health services in light of the Covid-19 pandemic. Methods We analysed electronic data between January and April 2020 for 2,534 patients referred to acute psychiatric services. We used interrupted time series analyses to compare trends in A&E and psychiatric presentations before and after lockdown, and tested for differences in patients’ demographics, symptom severity, and use of the Mental Health Act, before and after lockdown. Results There were 11% fewer psychiatric presentations the first week and 64% fewer A&E presentations the first month after lockdown initiated. A higher proportion of patients were detained under the Mental Health Act (22.2% vs 16.1%) and Mental Capacity Act (2.2 vs 1.1%)(χ2(2)=16.3, p<0.0001) and they experienced a longer duration of symptoms before seeking help from mental health services (χ 2(3)= 18.6, p<0.0001). A higher proportion of patients presented with psychotic symptoms (23.3% v 17.0%) or delirium (7.0 v 3.6%) and fewer had parasuicidal behaviour (43.8% v 52.0, χ2 (7)= 28.7, p<0.0001). A higher proportion were admitted to psychiatric inpatient units (22.2% vs 18.3%) (χ 2(6)= 42.8, p<0.0001) after lockdown Conclusions UK lockdown resulted in fewer psychiatric presentations but those who presented were more likely to have severe symptoms, be detained under the Mental Health Act and admitted to hospital. Psychiatric services should ensure provision of care for these patients as well as planning for those affected by future COVID-19 waves.

• Behavioral dynamics of COVID-19: estimating under-reporting, multiple waves, and adherence fatigue across 91 nations -

  Effective responses to the COVID-19 pandemic require reliable estimates of actual cases and deaths, and models that incorporate behavioral factors including differential priorities for allocating limited testing capacity, heterogeneous risk perceptions and resulting contact reductions, improved treatment, and adherence fatigue. We develop a behavioral dynamic model integrating these factors with asymptomatic transmission, disease acuity, and hospital capacity. Using a hierarchical Bayesian framework we estimate the model parameters with a panel dataset spanning all 91 nations with reliable testing data. Cumulative cases and deaths through 30 October 2020 are estimated to be 8.5 and 1.4 times greater than official reports, yielding an overall infection fatality rate (IFR) of 0.48%, with wide variation across nations and significant decline in IFR over time. Adherence fatigue is estimated to have increased cumulative cases by 61% through October 2020. Scenarios through March 2021 show modest policy interventions and behavior change could reduce cumulative cases ≈18%. The model endogenously generates the multiple waves of infection and mortality observed in many nations as behavioral responses to perceived risk cause the reproduction number to fluctuate around 1, but with death rates that vary by two orders of magnitude depending on responsiveness to perceived risks.

• Perspectives on SARS-COV2 pathogenesis, mutations and druggable targets -
  The coronavirus infection has evolved as a global crisis. According to the statistical reports, a total of 5,304,772 cases and 342,029 deaths are reported across the world (as of May 25, 2020). SARS-CoV-2 cases were first reported in Wuhan, China in December 2019. Wet market in Wuhan, where live and dead animals were kept in close contact was considered as the source of the viral outbreak. The main method of transmission for the SARS-CoV-2 virus is human to human contact. Typical symptoms of this viral infection include fever, cough and shortness of breath. The unavailability of approved medications or treatment protocols act as a paramount challenge for fighting against this pandemic. Researchers are focussing to develop therapeutic agents against SARS-CoV-2. But, increased prevalence of viral mutations, as well as differing human immune responses, act as crucial challenges for developing effective therapeutic agents. This review focuses on providing an overview of SARS-CoV-2 viral infection by considering several features such as etiology, pathological mechanisms, viral druggable targets triggering infection, hypothesis on viral mutations, therapeutic strategies as well as preliminary computational results on viral proteins.

• Inactivation of SARS-CoV-2 on surfaces and in solution with Virusend (TX-10), a novel disinfectant -
  Until an effective vaccine against SARS-CoV-2 is available on a widespread scale, the control of the COVID-19 pandemic is reliant upon effective pandemic control measures. The ability of SARS-CoV-2 to remain viable on surfaces and in aerosols, means indirect contact transmission can occur and so there is an opportunity to reduce transmission using effective disinfectants in public and communal spaces. Virusend (TX-10), a novel disinfectant, has been developed as a highly effective disinfectant against a range of microbial agents. Here we investigate the ability of VirusEnd (TX-10) to inactivation SARS-CoV-2. Using surface and solution inactivation assays, we show that VirusEnd (TX-10) is able to reduce SARS-CoV-2 viral titre by 4log10 PFU/mL within 1 minute of contact. Ensuring disinfectants are highly effective against SARS-CoV-2 is important in eliminating environmental sources of the virus to control the COVID-19 pandemic.

• Exploring Risks of Human Challenge Trials for COVID-19 -

  Human Challenge Trials (HCTs) are a potential method to accelerate development of vaccines and therapeutics. However, HCTs for COVID-19 pose ethical and practical challenges, in part due to the unclear and developing risks. In this paper, we introduce an interactive model for exploring some risks of a SARS-COV-2 dosing study, a prerequisite for any COVID-19 challenge trials. The risk estimates we use are based on a Bayesian evidence synthesis model which can incorporate new data on infection fatality rates (IFRs) to patients, and infer rates of hospitalization. We have also created a web tool to explore risk under different study design parameters and participant scenarios. Finally, we use our model to estimate individual risk, as well as the overall mortality and hospitalization risk in a dosing study. Based on the Bayesian model we expect IFR for someone between 20 and 30 years of age to be 17.5 in 100,000, with 95% uncertainty interval from 12.8 to 23.6. Using this estimate, we find that a simple 50-person dosing trial using younger individuals has a 99.1% (95% CI: 98.8% to 99.4%) probability of no fatalities, and a 92.8% (95% CI: 90.3% to 94.6%) probability of no cases requiring hospitalization. However, this IFR will be reduced in an HCT via screening for comorbidities, as well as providing medical care and aggressive treatment for any cases which occur, so that with stronger assumptions, we project the risk to be as low as 3.1 per 100,000, with a 99.85% (95% CI: 99.7% to 99.9%) chance of no fatalities, and a 98.7% (95% CI: 97.4% to 99.3%) probability of no cases requiring hospitalization.

• High-resolution mapping and characterization of epitopes in COVID-19 patients -

  Fine scale delineation of epitopes recognized by the antibody response to SARS-CoV-2 infection will be critical to understanding disease heterogeneity and informing development of safe and effective vaccines and therapeutics. The Serum Epitope Repertoire Analysis (SERA) platform leverages a high diversity random bacterial display library to identify epitope binding specificities with single amino acid resolution. We applied SERA broadly, across human, viral and viral strain proteomes in multiple cohorts with a wide range of outcomes from SARS-CoV-2 infection. We identify dominant epitope motifs and profiles which effectively classify COVID-19, distinguish mild from severe disease, and relate to neutralization activity. We identify a repertoire of epitopes shared by SARS-CoV-2 and endemic human coronaviruses and determine that a region of amino acid sequence identity shared by the SARS-CoV-2 furin cleavage site and the host protein ENaC-alpha is a potential cross-reactive epitope. Finally, we observe decreased epitope signal for mutant strains which points to reduced antibody response to mutant SARS-CoV-2. Together, these findings indicate that SERA enables high resolution of antibody epitopes that can inform data-driven design and target selection for COVID-19 diagnostics, therapeutics and vaccines.

• Diabetes and Mortality Among 1.6 Million Adult Patients Screened for SARS-CoV-2 in Mexico -

  Background: Whether diabetes is associated with COVID-19-related mortality remains unclear. Methods: In this retrospective case-series study we examined the risk of death associated with self-reported diabetes in symptomatic adult patients with laboratory-confirmed COVID-19 who were identified through the System of Epidemiological Surveillance of Viral Respiratory Disease in Mexico from January 1 through November 4, 2020. Survival time was right-censored at 28 days of follow-up. Results: Among 757,210 patients with COVID-19 included in the study, 120,476 (16%) had diabetes and 80,616 died. Patients with diabetes had a 49% higher relative risk of death than those without diabetes (Cox proportional-hazard ratio; 1.49 (95% confidence interval [CI], 1.47-1.52), adjusting for age, sex, smoking habit, obesity, hypertension, immunodeficiency, and cardiovascular, pulmonary, and chronic renal disease. The relative risk of death associated with diabetes decreased with age (P=0.004). The hazard ratios were 1.66 (1.58-1.74) in outpatients and 1.14 (1.12-1.16) in hospitalized patients. The 28-day survival for inpatients with and without diabetes was, respectively, 73.5% and 85.2% for patients 20-39 years of age; 66.6% and 75.9% for patients 40-49 years of age; 59.4% and 66.5% for patients 50-59 years of age; 50.1% and 54.6% for patients 60-69 years of age; 42.7% and 44.6% for patients 70-79 years of age; and 38.4% and 39.0% for patients 80 years of age or older. In patients without COVID-19 (878,840), the adjusted hazard ratio for mortality was 1.78 (1.73-1.84). Conclusion: In symptomatic adult patients with COVID-19 in Mexico, diabetes was associated with higher mortality. This association decreased with age.

• Systematic evaluation of transcriptomic disease risk and diagnostic biomarker overlap between COVID-19 and tuberculosis: a patient-level meta-analysis -

  Background The novel coronavirus, SARS-CoV-2, has increased the burden on healthcare systems already strained by a high incidence of tuberculosis (TB) as co-infection and dual presentation are occurring in syndemic settings. We aimed to understand the interaction between these diseases by profiling COVID-19 gene expression signatures on RNA-sequencing data from TB-infected individuals. Methods We performed a systematic review and patient-level meta-analysis by querying PubMed and pre-print servers to derive eligible COVID-19 gene expression signatures from human whole blood (WB), PBMCs or BALF studies. A WB influenza dataset served as a control respiratory disease signature. Three large TB RNA-seq datasets, comprising multiple cohorts from the UK and Africa and consisting of TB patients across the disease spectrum, were chosen to profile these signatures. Putative COVID-19 risk scores were generated for each sample in the TB datasets using the TBSignatureProfiler package. Risk was stratified by time to TB diagnosis in progressors and contacts of pulmonary and extra-pulmonary TB. An integrative analysis between TB and COVID-19 single-cell RNA-seq data was performed and a population-level meta-analysis was conducted to identify shared gene ontologies between the diseases and their relative enrichment in COVID-19 disease severity states. Results 35 COVID-19 gene signatures from nine eligible studies comprising 98 samples were profiled on TB RNA-seq data from 1181 samples from 853 individuals. 25 signatures had significantly higher COVID-19 risk in active TB (ATB) compared with latent TB infection (p <0.005), 13 of which were validated in two independent datasets. FCN1- and SPP1-expressing macrophages enriched in BALF during severe COVID-19 were identified in circulation during ATB. Shared perturbed ontologies included antigen presentation, epigenetic regulation, platelet activation, and ROS/RNS production were enriched with increasing COVID-19 severity. Finally, we demonstrate that the overlapping transcriptional responses may complicate development of blood-based diagnostic signatures of co-infection. Interpretation Our results identify shared dysregulation of immune responses in COVID-19 and TB as a dual risk posed by co-infection to COVID-19 severity and TB disease progression. These individuals should be followed up for TB in the months subsequent to SARS-CoV-2 diagnosis.

• Monitoring and Epidemiological Trends of Coronavirus Disease (COVID-19) Around The World -
  COVID-19 has struck fear into populaces all through the world and shocked the worldwide restorative community, with the World Health Organization (WHO) pronouncing it a widespread as it were approximately three months after the flare-up of the infection. A new different virus (primarily called ‘Novel Coronavirus 2019-nCoV’) causing severe acute respiratory syndrome (coronavirus disease COVID-19) emerged in Wuhan, Hubei Province, China in December 2019 and rapidly spread to other parts of China and other countries around the world. The outbreak of the novel coronavirus disease (COVID-19) has caused more than 850,000 people infected and approx. 40000 of deaths in more than 190 countries up to March 2020, extremely affecting economic and social development. Presently, the number of infections and deaths is still increasing rapidly. COVID-19 seriously threatens human health, production, life, social functioning and international relations. In the fight against COVID-19, Geographic Information Systems (GIS) and big data technologies have played an important role in many aspects. This paper describes the usage of practical GIS and mapping dashboards and applications for monitoring the coronavirus epidemic and related activities as they spread around the world. At the facts level, in the generation of massive data, information no longer come on the whole from the authorities but are gathered from greater diverse enterprises. As of now and for a long time in the future, the improvement of GIS should be fortified to create a data-driven framework for fast information securing, which implies that GIS ought to be utilized to fortify the social operation parameterization of models and methods, particularly when giving back for social administration.

• Evaluating aerosol and splatter during orthodontic debonding: implications for the COVID-19 pandemic -
  Introduction: Dental procedures often produce splatter and aerosol which have potential to spread pathogens such as SARS-CoV-2. Mixed guidance exists on the aerosol generating potential of orthodontic procedures. The aim of this study was to evaluate aerosol and/or splatter contamination during an orthodontic debonding procedure. Material and Methods: Fluorescein dye was introduced into the oral cavity of a mannequin. Orthodontic debonding was carried out in triplicate with filter papers placed in the immediate environment. Composite bonding cement was removed using a slow-speed handpiece with dental suction. A positive control condition included a high-speed air-turbine crown preparation. Samples were analysed using digital image analysis and spectrofluorometric analysis. Results: Contamination across the 8-metre experimental rig was 3% of the positive control on spectrofluorometric analysis and 0% on image analysis. There was contamination of the operator, assistant, and mannequin, representing 8%, 25%, and 28% of the positive control spectrofluorometric measurements, respectively. Discussion: Orthodontic debonding produces splatter within the immediate locality of the patient. Widespread aerosol generation was not observed. Conclusions: Orthodontic debonding procedures are low risk for aerosol generation, but localised splatter is likely. This highlights the importance of personal protective equipment for the operator, assistant, and patient.

• How Families Matter for Health Inequality during the COVID-19 Pandemic -
  We theorize that social conditions surrounding the COVID-19 pandemic have the potential to increase the importance of families for health and widen existing inequalities. We suggest three primary tenets important for understanding families and health during COVID-19. First, risks of specific COVID-19 outcomes and other health problems are unevenly distributed across families. Second, how families impact health during the COVID-19 pandemic is conditional on public policies, organizational decisions, and concurrent events. Third, many health inequalities driven by racism, sexism, classism, and other oppressive societal force are amplified during COVID-19, but the extent to which this is occurring is shaped by families and by the public policies, organizational decisions, and concurrent events that also impact families and health. As health disparities continue to emerge from this pandemic, we call on researchers and policy-makers to pay attention to the multiple ways that families matter.

• 3D8, a nucleic acid-hydrolyzing scFv, confers antiviral activity against SARS-CoV-2 and multiple coronaviruses in vitro -
  The current pandemic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pose a critical public health threat worldwide. Coronaviruses (subfamily Orthocoronavirinae, family Coronaviridae, order Nidovirales) are a group of enveloped positive-sense single-stranded RNA viruses. Six pathogenic human coronaviruses, likely zoonotic viruses, cause the common cold in humans. A new emerging coronavirus, SARS-CoV-2, become a crucial etiology for the Coronavirus-induced disease 19 (COVID-19). However, effective therapeutics and vaccines against multiple coronaviruses remain unavailable. This study aimed to investigate an antiviral molecule, single chain variable fragment (scFv), against SARS-CoV-2 and other coronaviruses. 3D8, a recombinant scFv, exhibits broad-spectrum antiviral activity against DNA and RNA viruses owing to its nucleic acid-hydrolyzing property. Here, we report that 3D8 scFv inhibited the replication of SARS-CoV-2, human coronavirus OC43 (HCoV-OC43), and porcine epidemic diarrhea virus (PEDV). Our results revealed the prophylactic and therapeutic effects of 3D8 scFv against SARS-CoV-2 in Vero E6 cells. Immunoblot and plaque assays showed the absence of coronavirus nucleoproteins and infectious particles in 3D8 scFv-treated cells, respectively. In addition, we observed the antiviral effects of 3D8 against HCoV-OC43 and PEDV. In conclusion, this study provides insights into the broad-spectrum antiviral agent of 3D8 scFv; thus, it could be considered a potential antiviral countermeasure against SARS-CoV-2 and zoonotic coronaviruses.

• Global analysis of protein-RNA interactions in SARS-CoV-2 infected cells reveals key regulators of infection -
  Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19. SARS-CoV-2 relies on cellular RNA-binding proteins (RBPs) to replicate and spread, although which RBPs control SARS-CoV-2 infection remains largely unknown. Here, we employ a multi-omic approach to identify systematically and comprehensively which cellular and viral RBPs are involved in SARS-CoV-2 infection. We reveal that the cellular RNA-bound proteome is remodelled upon SARS-CoV-2 infection, having widespread effects on RNA metabolic pathways, non-canonical RBPs and antiviral factors. Moreover, we apply a new method to identify the proteins that directly interact with viral RNA, uncovering dozens of cellular RBPs and eight viral proteins. Amongst them, several components of the tRNA ligase complex, which we show regulate SARS-CoV-2 infection. Furthermore, we discover that available drugs targeting host RBPs that interact with SARS-CoV-2 RNA inhibit infection. Collectively, our results uncover a new universe of host-virus interactions with potential for new antiviral therapies against COVID-19.

• Decline in SARS-CoV-2 Antibodies After Mild Infection Among Frontline Health Care Personnel in a Multistate Hospital Network - 12 States, April-August 2020 - Most persons infected with SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), develop virus-specific antibodies within several weeks, but antibody titers might decline over time. Understanding the timeline of antibody decline is important for interpreting SARS-CoV-2 serology results. Serum specimens were collected from a convenience sample of frontline health care personnel at 13 hospitals and tested for antibodies to SARS-CoV-2 during April 3-June 19, 2020, and again…

• Bacillus Calmette-Guerin vaccination Policy and Consumption of Ammonium Chloride-Enriched Confectioneries May Be Factors Reducing COVID-19 Death Rates in Europe - CONCLUSIONS: The results seem to confirm an association between BCG-positive vaccination policy and salmiak consumption, and lower death rates from COVID-19. Implementing BCG vaccination policy and fortification of foods with salmiak (NH4Cl) may have a significant impact on the control of SARS-CoV epidemic.

• Dysregulated immunity in SARS-CoV-2 infected pregnant women - CONCLUSIONS AND RELEVANCE: SARS-CoV-2 infection during pregnancy was characterized by placental inflammation and reduced antiviral antibody responses, which may impact the efficacy of COVID-19 therapeutics in pregnancy. The long-term implications of placental inflammation for neonatal health also requires greater consideration.

• Novel gene-specific translation mechanism of dysregulated, chronic inflammation reveals promising, multifaceted COVID-19 therapeutics - Hyperinflammation and lymphopenia provoked by SARS-CoV-2-activated macrophages contribute to the high mortality of Coronavirus Disease 2019 (COVID-19) patients. Thus, defining host pathways aberrantly activated in patient macrophages is critical for developing effective therapeutics. We discovered that G9a, a histone methyltransferase that is overexpressed in COVID-19 patients with high viral load, activates translation of specific genes that induce hyperinflammation and impairment of T cell…

• The Development of a Novel Nanobody Therapeutic for SARS-CoV-2 - Combating the COVID-19 pandemic requires potent and low-cost therapeutics. We identified a novel series of single-domain antibodies (i.e., nanobody), Nanosota-1, from a camelid nanobody phage display library. Structural data showed that Nanosota-1 bound to the oft-hidden receptor-binding domain (RBD) of SARS-CoV-2 spike protein, blocking out viral receptor ACE2. The lead drug possessing an Fc tag ( Nanosota-1C-Fc ) bound to SARS-CoV-2 RBD with a K (d) of 15.7picomolar (∼3000 times more tightly…

• One novel virus, different beliefs as playmakers towards disease spread in Africa: looking at COVID-19 from a religious lens - Religious and spiritual observances that draw large people together are pervasive in many parts of the world, including Africa. With the recent emergence of COVID-19, these mass religious gatherings may pose significant threats to human health. Given the compromised healthcare systems in many parts of Africa, faith-based institutions have a huge responsibility towards the management of the potential spread of the virus through effective organizational strategies or interventions. This essay…

• Plasma-activated water: An alternative disinfectant for S protein inactivation to prevent SARS-CoV-2 infection - SARS-CoV-2 is a highly contagious virus and is causing a global pandemic. SARS-CoV-2 infection depends on the recognition of and binding to the cellular receptor human angiotensin-converting enzyme 2 (hACE2) through the receptor-binding domain (RBD) of the spike protein, and disruption of this process can effectively inhibit SARS-CoV-2 invasion. Plasma-activated water efficiently inactivates bacteria and bacteriophages by causing damage to biological macromolecules, but its effect on coronavirus…

• Inhibiting the reproduction of SARS-CoV-2 through perturbations in human lung cell metabolic network - Viruses rely on their host for reproduction. Here, we made use of genomic and structural information to create a biomass function capturing the amino and nucleic acid requirements of SARS-CoV-2. Incorporating this biomass function into a stoichiometric metabolic model of the human lung cell and applying metabolic flux balance analysis, we identified host-based metabolic perturbations inhibiting SARS-CoV-2 reproduction. Our results highlight reactions in the central metabolism, as well as amino…

• Structure of nonstructural protein 1 from SARS-CoV-2 - The periodic emergence of novel coronaviruses (CoVs) represents an ongoing public health concern with significant health and financial burden worldwide. The most recent occurrence originated in the city of Wuhan, China where a novel coronavirus (SARS-CoV-2) emerged causing severe respiratory illness and pneumonia. The continual emergence of novel coronaviruses underscores the importance of developing effective vaccines as well as novel therapeutic options that target either viral functions or…

• Cryo-EM Structure of an Extended SARS-CoV-2 Replication and Transcription Complex Reveals an Intermediate State in Cap Synthesis - Transcription of SARS-CoV-2 mRNA requires sequential reactions facilitated by the replication and transcription complex (RTC). Here, we present a structural snapshot of SARS-CoV-2 RTC as it transitions toward cap structure synthesis. We determine the atomic cryo-EM structure of an extended RTC assembled by nsp7-nsp8(2)-nsp12-nsp13(2)-RNA and a single RNA-binding protein, nsp9. Nsp9 binds tightly to nsp12 (RdRp) NiRAN, allowing nsp9 N terminus inserting into the catalytic center of nsp12 NiRAN,…
