Research suggests toll-like receptor 4 appears to play role in severe COVID

A group of researchers re-evaluated their previously proposed hypothesis, which stated that the TLR4 activated by the spike glycoprotein S1 domain increases ACE2 expression and, thereby, aids in COVID-19 infection.

Study illuminates the link between cholesterol and Alzheimer's-associated toxic protein clumps

A team co-led by scientists at Scripps Research has used advanced imaging methods to reveal how the production of the Alzheimer's-associated protein amyloid beta (Aβ) in the brain is tightly regulated by cholesterol.

Optical nanoscopy reveals how SARS-CoV-2 infection alters human airway cells

How do viruses reorganize host cells with spatial and molecular specificity? Researchers from the Netherlands provided new insights in a recent study posted to the bioRxiv* preprint server, where they use optical nanoscopy to look at severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-triggered changes in primary human airway cells.

VPS29 gene facilitates coronavirus cell entry

In a research paper recently uploaded to the bioRxiv* preprint server by Poston et al. (August 8th, 2021), common host factors amongst several zoonotic pathogens are explored by CRISPR-Cas9 screening in human lung cells, focusing in particular on the betacoronavirus genus.

Microbe transmitted between mosquitoes could be key to controlling malaria

A microbe that is transmitted between male and female mosquitoes but can also block reproduction could be key to controlling malaria by targeting its release into mosquito populations, a study says.

Insulin resistance could be due to changes in specific subtype of fat cells, study suggests

It is well known that fat cells can influence our sensitivity to insulin. Now, researchers at Karolinska Institutet in Sweden have discovered that there are three different subtypes of mature fat cells in white adipose tissue and that it is only one of these, called AdipoPLIN, that responds to insulin.

Cardioprotective role of HIF1α in COVID-19 patients

The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which first emerged in Wuhan, China, in late December 2019, has quickly become the most urgent issue facing scientists worldwide. It has been reported that the respiratory infection causes cardiac dysfunction in 25-55% patients, including hospitalized patients and non-critical patients.
