Evidence of link between ACE2 genotype and COVID-19 disease severity

A new study published on the preprint server medRxiv in June 2020 shows that variants in the ACE2 gene which encodes the enzyme receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19 disease, are linked to the risk of severe disease.

Exposure to SARS-CoV-2 can induce virus-specific T cell responses without seroconversion

A new study by researchers at Strasbourg University Hospital and published on the preprint server medRxiv* in June 2020 shows that COVID-19 antibody responses may sometimes be lacking following exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This could lead to a significant underestimation of the number of infections and the number of individuals who have achieved immunity.

Computational tool provides growth rate and acceleration analysis of COVID-19 pandemic

Researchers at São Paulo State University (UNESP) in Araçatuba, Brazil, have developed a computational tool that acts like a "COVID-19 accelerometer," plotting in real time the rate at which growth is accelerating or decelerating in more than 200 countries and territories.

Balanced B and T cell response required to control SARS-CoV-2

A new study by researchers in the Netherlands and published on the preprint server bioRxiv in June 2020 describes the differences in T and B cell responses seen in patients with severe COVID-19.

Using stem cells to study the developmental effects of Neandertal DNA

Protocols that allow the transformation of human induced pluripotent stem cell (iPSC) lines into organoids have changed the way scientists can study developmental processes and enable them to decipher the interplay between genes and tissue formation, particularly for organs where primary tissue is not available.

SARS-CoV-2 mutation reduces S1 shedding, increases infective potential

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the seventh coronavirus known to infect humans. SARS-CoV-2 emerged in the last month of 2019 in Wuhan, China, sparking off the ongoing COVID-19 pandemic. This virus enters the host cells through receptor binding and membrane fusion between the viral and host cell membrane.

Controlling SARS-CoV-2 upon resumption of the Spanish football league

The coronavirus disease (COVID-19) pandemic first emerged in Wuhan City, China, in December 2019. Since then, it has spread throughout the world, infecting more than 8 million people. Social distancing measures were imposed in most countries, isolating people in their homes, banning congregations, including schools, parties, and even sports events.

Effect of human genes on severity and infectivity of SARS-CoV-2

Now, a new paper published on the preprint server medRxiv* reports the results of an analysis of the association between the genetic variants in the patients and the clinical progression of the disease. The study included 332 patients hospitalized with COVID-19 in a single-center, with widely varying laboratory and clinical features. There were 25, 12, and 17 patients with asymptomatic, mild, and critical disease.
