Susceptibility to SARS-CoV-2 infection varies across bat species

A recent study by researchers at Wuhan University, China, reveals that many bat species are not potential carriers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) because of genetic mutations in angiotensin-converting enzyme 2 (ACE2) that prevent the entry of viruses inside bat cells. The study is currently available on the bioRxiv* preprint server.

Metabolite signature reveals signs of multi-organ damage in COVID-19 patients

SARS-CoV-2, the virus responsible for COVID-19, can cause a wide range of symptoms, from none at all to severe respiratory stress, multi-organ failure and death.

Study reveals how B cells react to SARS-CoV-2

In an exciting immunological medRxiv preprint paper, researchers from Germany and Russia analyzed adaptive immune response in severely affected patients with coronavirus disease (COVID-19). They demonstrated a protracted immune reaction characterized by egress of B lymphocytes into the blood.

Pfizer, BioNTech COVID-19 vaccine candidate shows promise in preclinical study

Researchers in the United States and Germany have conducted a study demonstrating the preclinical efficacy of a new candidate vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

Researchers discover a new way to limit inflammation from adjuvants in vaccines

Adjuvants are a key ingredient of many modern vaccines, working to unleash an immune response that helps protect the body from disease. Many scientists believe that adjuvants are they key to developing new kinds of vaccines for hard-to-vaccinate viruses, like HIV.

UVA radiation may contribute to inactivation of SARS-CoV-2 by sunlight

An international team of researchers has made important discoveries about the sunlight inactivation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that suggest this process is not currently adequately understood.

Host gene editing main driving force of SARS-CoV-2 mutations

A new study published on the aRxiv preprint server in September 2020 shows that the host immune response, mediated by two RNA editors, causes the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to adapt and change strain characteristics.

Convalescent plasma could be an effective treatment for children with COVID-19

Early findings from researchers at Children's Hospital of Philadelphia (CHOP) show that convalescent plasma appears to be a safe and possibly effective treatment for children with life-threatening cases of COVID-19.

Scientists explain why men are at higher risk from COVID-19

Published in the journal PLOS Biology, the study aimed to provide a better understanding of the mechanisms that drive the varying responses of the infected individuals among different patient demographics, including sex and age.

Researchers discuss the role of chemical senses in disease and social interactions in humans, animals

Across 5 days in August (3rd-7th), scientists from around the world gathered virtually to present and discuss new information on the role of the chemical senses in disease, nutrition, and social interactions in humans and animals.

Warm weather increases human mobility, and SARS-CoV-2 transmission

A recent study published in the preprint server medRxiv in September 2020 shows that the effect of climatic factors such as temperature and humidity is mediated mostly through human mobility. Thus, human behavioral changes are still the mainstay of containment rather than hoping for weather conditions to keep the virus at bay.

COVID-19 in pregnancy doubles odds of preterm delivery

The COVID-19 pandemic is continuing to cause huge social, economic, and health-related costs throughout the world, especially in Spain. Clinicians are still coming to terms with the range of health conditions wrought by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A new study published on the preprint server medRxiv* in September 2020 shows that this infection results in fetal and maternal complications.

Vitamin D deficiency can increase risk of COVID-19

Researchers from Israel have found that there could be a link between deficiency of vitamin D and infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Their study titled, “The link between vitamin D deficiency and COVID-19 in a large population,” has been released pre-publication at the medRxiv* server.

AstraZeneca COVID-19 vaccine trial paused due to suspected adverse reaction

The coronavirus disease (COVID-19) pandemic is rippling across the globe, with over 27.47 million reported cases. With the vast spread of the virus, scientists are racing to gain the approval of candidate vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19 disease and Multisystem Inflammatory Syndrome in Children (MIS-C).

Comparing COVID-19 spread between cities and the countryside

The new study, which was published in the open-source medRxiv and has not yet been peer-reviewed, shows that superspreaders and population heterogeneity are the core factors explaining the discrepancy of cases.

SARS-CoV-2 does not pose a food safety risk, health agency says

Now, a new report by the International Commission on Microbiological Specifications for Foods (ICMSF) highlights the link between SARS-CoV-2 infection and food safety. ICMSF is a global non-government organization that aims to provide information on food safety and human health.

'Molecular brake' on the immune system could be potential treatment target for severe COVID-19

Older people and people with underlying medical conditions are at particular risk of severe COVID-19. A group of researchers from Charité - Universitätsmedizin Berlin have discovered one possible reason for this vulnerability.

Memory B cells indicate durable immunity in COVID-19

Now a new study by researchers at SUNY Upstate Medical University and published recently on the preprint server medRxiv in September 2020 shows that memory B cells are upregulated in convalescent COVID-19 patients, correlating with a better immune response and shorter symptom duration.

Scientists develop a rapid, reliable and low-cost COVID-19 antibody test

Robust and widespread antibody testing has emerged as a key strategy in the fight against SARS-CoV-2, the virus responsible for the COVID-19 pandemic.

Study reveals complex immunology behind MIS-C in children with COVID-19

In a recent paper published in the prestigious journal Cell, researchers from Sweden and Italy show that inflammatory response in Multisystem Inflammatory Syndrome in Children associated with coronavirus disease (COVID-19) differs from the cytokine storm found in severe acute illness, involving autoantibodies at the same time and sharing several features with Kawasaki disease.
