Small molecule drugs binding Mac1 domain of SARS-CoV-2

Now, an intriguing new study out of the University of Wisconsin-Milwaukee reveals that numerous small molecule drugs like the proton pump inhibitors omeprazole and rabeprazole bind the important Mac1 domain on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus.

Real-time tracking of protein filaments in the nuclear pore complex

In human cells, the nucleus is enclosed by a structure called the nuclear pore complex (NPC). It acts as a 'gatekeeper' controlling the transport of molecules between the nucleus and the surrounding cytoplasm (the protein-containing solution in the inside of a cell).

Researchers discover new candidate for raw material synthesis through gene transfer

Cyanobacteria hardly need any nutrients and use the energy of sunlight. Bathers are familiar with these microorganisms - often incorrectly called "blue-green algae" - as they often occur in waters.

SARS-CoV-2 infection modeling in iPSC-derived type 2 cells

The most fatal form of COVID-19 disease is acute respiratory distress syndrome (ARDS), caused by direct viral injury as well as indirect noxious effects caused by cytotoxic chemicals and inflammatory processes. A new study published on the preprint server bioRxiv* in June 2020 shows that this is partly due to the rapid onset of inflammation caused by the infection of type 2 alveolar cells with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Novavax SARS-CoV-2 vaccine candidate shows promise in animal models

A new study published on the preprint server bioRxiv in June 2020 shows that a candidate spike protein vaccine can induce neutralizing antibodies, antiviral T cell responses, and protection against infection.

Repurposed drug for acute lung injury in COVID-19

Now, a new study addresses the possible use of an FDA-approved monoclonal antibody, called fostamatinib, a spleen tyrosine kinase inhibitor (SYK), to reduce the levels of mucin-1, a molecule associated with acute lung injury and acute respiratory distress syndrome (ARDS). People who have severe COVID-19 disease may develop ARDS.

Researchers discover a protein that protects B cells from stress-induced cell death

Whenever a germ gets into the human body, the immune system usually responds immediately to fight off the enemy attacker. One of our defense system's most important strategies involves B lymphocytes, also known as B cells, which produce antibodies that target and neutralize pathogens.

Study identifies small molecule inhibitors of SARS-CoV-2 which block key cellular kinases

Antiviral drug screen of kinase inhibitors, which was done by researchers from the University of California and Cedars-Sinai Medical Center, identified cellular signaling pathways critical for SARS-CoV-2 replication and revealed an important mechanism of host-pathogen interaction vital for further drug research. Their results are available on the bioRxiv* preprint server.

Groundbreaking experiment marks first successful delivery of mitochondria to liver cells

University of Connecticut researcher Dr. George Wu recently published a paper in the Journal of Gastroenterology and Hepatology outlining his successful experiment delivering mitochondria to liver cells.

Abnormal findings in testicular tissue of COVID-19 patients, SARS-CoV-2 mostly undetected

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused over 9.263 million cases and taken more than 477,000 lives as of June 24, 2020 – just six months after the initial outbreak in Wuhan, China, was reported. The illness, called COVID-19 disease, caused by SARS-CoV-2 is a severe pneumonic illness, caused by the entry of the virus into the type II alveolar cells.

Growth, adaptation and neutralization of SARS-CoV-2 with acute-phase serum

One recent study published on the preprint server bioRxiv in June 2020 reports the results of growing and characterizing the virus, as well as the development of neutralizing antibodies in the serum of acutely infected hospitalized patients with COVID-19.

First genome-wide CRISPR screen reveals genes that control SARS-CoV-2 infection

By performing a genome-wide CRISPR screen on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), U.S. researchers identified novel proviral genes and pathways, and highlighted host genes that may regulate coronavirus disease (COVID-19) pathogenesis, as well as revealing potential targets for novel treatment approaches. Their findings are currently available on the bioRxiv* preprint server.

Tracing coronavirus habitats with genomics

Now, a new study by researchers at the University of Ottawa and published on the preprint server bioRxiv in June 2020 reports the differences in genomes of viruses that are exposed to antiviral proteins vs. those that are not. This host-derived pressure on the virus to adapt may help devise newer ways to build an effective vaccine.

Prodigiosin-based nanoformulation selectively disrupts cancer cells

Together with colleagues from the University of Palermo, KFU employees offer a nano preparation based on biocompatible halloysite nanotubes and bacterial pigment prodigiosin; the latter is known to selectively disrupt cancer cells without damaging the healthy ones.

Study unravels role of a protein in osteoclast generation

Bone-dissolving cells called osteoclasts are derived from a type of immune cells called macrophages. They are necessary for the maintenance and renewal of bones.

SARS-CoV-2 gene deletions may cause milder infections and increase human-to-human transmission

In their recent paper released on the bioRxiv preprint server, a research group from Spain demonstrated how genome changes and deletions in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could represent a strategy of natural selection used for lessening the impact of infection in order to increase viral transmission potential.

LMU researchers discover how a microRNA preserves vascular integrity

Ludwig-Maximilian-Universitaet in Munich researchers have discovered a hitherto unknown molecular function of a specific microRNA that preserves integrity of the endothelium and reduces the risk of atherosclerosis.

Study uncovers how cancer cells protect themselves from viruses

Researchers at the Francis Crick Institute have uncovered how cancer cells protect themselves from viruses that are harmful to tumors but not to healthy cells. These findings could lead to improved viral treatments for the disease.

How COVID-19 affects the nervous system

A new paper published in the journal JAMA Neurology in May 2020 discusses the presentation and complications of COVID-19 with respect to the nervous system.

Heparin resistance among COVID-19 patients admitted to ICU

A new study has shown that COVID-19 patients admitted to the Intensive care unit may be resistant to the naturally occurring anticoagulant Heparin. The study titled, “Heparin resistance in COVID‑19 patients in the intensive care unit,” was published in the latest issue of the Journal of Thrombosis and Thrombolysis.
