Researchers identify the target structures for T-cell response against SARS-CoV-2

Our immune system can efficiently fend off viral diseases. Two types of immune cells play an important role in this process: The T-cells, which firstly can directly destroy virus-infected cells and secondly enable the formation of efficient, virus-neutralizing antibodies by B-cells.

Discovery of high affinity binders for SARS-CoV-2 spike protein

An exciting, 'tour-de-force' paper by researchers from the Massachusetts Institute of Technology describes de novo discovery of high-affinity peptide binders for SARS-CoV-2 spike glycoprotein, which opens the door for the development of rapid viral identification or conjugates for virus-directed delivery of therapeutics.

SARS-CoV-2 D614G variant enhances infectivity, replication and transmission

Researchers in the United States and Japan have conducted a study showing a common mutation in the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) - the agent that causes coronavirus disease 2019 (COVD-19) - enhances the infectivity, replication, and early transmission of the virus.

Newly developed fusion protein could improve COVID-19 research

Researchers at the Paul Scherrer Institute in Switzerland have developed a high-quality recombinant virus protein that could be applied in the development of vaccines against the 2019 novel coronavirus (2019-nCoV) and in the detection of novel viruses or antibodies.

SARS-CoV-2 infects human embryonic epithelial and lung cells

As COVID-19 continues to spread the world over, investigators are still trying to understand how it ravages the human body. A recent study published on the preprint server bioRxiv in September 2020 shows that the virus is capable of infecting human embryonic cells that are destined to form the epithelial surfaces of the body, both internal and external, as well as lung cells.

Computer model unravels mystery behind severe inflammation in people with COVID-19

A study from the University of Pittsburgh School of Medicine and Cedars-Sinai addresses a mystery first raised in March: Why do some people with COVID-19 develop severe inflammation?
