Novel super-activating macrophage receptor could explain hyper-inflammation in severe COVID-19

Immunity is a curious thing. While essential in protecting the body against invading pathogens and foreign antigens, it can also turn against the body and trigger destructive immunological processes. A new study published on the preprint server bioRxiv* in November 2020 reports on the role played by hyperactive macrophages in a range of acute and chronic hyper-inflammatory conditions.

Lessons from USS Theodore Roosevelt on limiting shipborne COVID-19 outbreaks

A new study published on the preprint server medRxiv* in November 2020 discusses such a scenario in terms of various possible approaches. It suggests that a viable strategy could be evacuating everyone from the ship and extensive surveillance testing.

SARS-CoV-2 spike glycoprotein optimized for conditions present in human airways

Researchers from Belgium and Germany demonstrated how the spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is fine-tuned towards the temperature and protease conditions of the human airways, which in turn enhances viral transmission and subsequent pathology. Their study is available on the bioRxiv* preprint server.

Severe COVID-19 linked to age, body mass index and ABO blood group

With the COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infecting over 50 million people worldwide with hundreds of thousands experiencing severe respiratory illness, researchers have been trying to find the factors associated with severe disease. From the start of the pandemic in March this year, several studies have indicated heart disease, high blood pressure, diabetes, obesity, etc. could be linked to severe disease. Now German researchers have published a study on the association between severe respiratory infection caused by SARS CoV-2 and factors such as age, body mass index (BMI) and ABO blood group.

Identifying SARS-CoV-2 spike protein mutations resistant to antibodies

Using a set of different monoclonal antibodies, researchers determined different mutations in the SARS-CoV-2 spike protein that leads to resistance. Understanding these resistant mutations is important in developing effective therapeutic strategies.

Recommendations for initial prioritization of vaccination measures against COVID-19

The first COVID-19 vaccines could be authorized as early as the start of 2021. However, in all likelihood, there will not be sufficient vaccine doses in the beginning for all the people willing to undergo vaccination.
