Study shows why ApoE4 increases risk of Alzheimer's disease

Apolipoprotein E (ApoE) is kind of like a delivery service for the human brain. It supplies neurons with important nutrients, including with polyunsaturated fatty acids - which are building blocks of the membranes surrounding the neurons.

Scientists pinpoint mutations that increase bacterial deadliness

As far as humans are concerned, bacteria can be classified as either harmful, pathogenic bacteria and harmless or beneficial non-pathogenic bacteria.

Platelets may be contributing to COVID-19

The current pandemic of COVID-19 is characterized mainly by severe acute respiratory distress of the lungs, but other organ dysfunctions are also being observed, including the heart and blood vessels. Now, a new paper published on the preprint server medRxiv* in June 2020 describes the abnormal activation of platelets in this disease and the link between this phenomenon and poor outcomes for COVID-19 patients.

Prevention of sugar uptake can make cancer cells more sensitive to chemotherapy

By preventing sugar uptake, researchers succeeded in increasing the cancer cells' sensitivity to chemotherapeutic treatment.

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.

Direct structural link between SARS-CoV-2 and essential fatty acid

Now, a new study published on the preprint server bioRxiv in June 2020 reports the discovery of a novel free fatty acid (FFA) binding pocket on the SARS-CoV-2 virus that could explain in part the viral effects of hyperinflammation, immune modulation, and membrane structure.

Nanosponges attract coronavirus away from lung cells, study shows

Imagine if scientists could stop the coronavirus infection in its tracks simply by diverting its attention away from living lung cells? A new therapeutic countermeasure, announced in a Nano Letters study by researchers from Boston University's National Emerging Infectious Diseases Laboratories and the University of California San Diego, appears to do just that in experiments that were carried out at the NEIDL in Boston.

Cyclosporin study may pave way for treating diseases related to mitochondrial dysfunction

Cyclic peptide molecules of the fungal origin called cyclosporins were discovered in 1970's, and cyclosporin A soon became an important drug due to its immunosuppressive activity.

Scientists use CRISPR tool to make rapid, precise cuts in genomic material

In a series of experiments using human cancer cell lines, scientists at Johns Hopkins Medicine say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel known as CRISPR, and observe how specialized cell proteins repair the exact spot where the gene was cut.

Study paints clear picture of how a protein that calms brain activity works

As the body goes about its daily business, molecules called neurotransmitters control the level of electrical activity within the brain.

Researchers use cellular nanosponges to soak up SARS-CoV-2

Scientists are working overtime to find an effective treatment for COVID-19, the illness caused by the new coronavirus, SARS-CoV-2.

Nanosponges could attack and neutralize SARS-COV-2 virus

Nanoparticles cloaked in human lung cell membranes and human immune cell membranes can attract and neutralize the SARS-CoV-2 virus in cell culture, causing the virus to lose its ability to hijack host cells and reproduce.

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.

Newfound knowledge may prove valuable to understand human nerve cells

Researchers discover what's behind nature's perhaps largest erection - which is not that big PLANT BIOLOGY.

Glycans "lock and load" the SARS-CoV-2 spike protein for infection

A new study by scientists from the University of California San Diego, USA and Maynooth University, Ireland and published on the preprint server bioRxiv* in June 2020 reports preliminary results showing that the spike protein of the SARS-CoV-2, as well as its glycan coat, has “hitherto unseen functional and structural” properties. These may be useful in designing novel therapeutics to target this molecule.

Steroidal drugs subvert SARS-CoV-2 interaction with ACE2 receptors

A new study by Italian researchers and published online on the preprint server bioRxiv* in June 2020 reports the ability of several existing steroidal drugs to reduce the binding of the SARS-CoV-2 to the ACE2 receptor. This could help define newer strategies using viral entry blockers to reduce viral load.

Remdesivir prevents replication of SARS-CoV-2 in human intestinal organoids

A new German study published on the preprint server bioRxiv* in June 2020 shows that the drug remdesivir can reduce the replication of SARS-CoV-2 in human intestinal organoids.

Race-related differences in genetic determinants of COVID-19 severity

Researchers at the University of Iowa have identified differences in gene expression levels between African Americans and European Americans that may explain the disproportionately higher rates of coronavirus disease 2019 (COVID-19) cases and related deaths among African Americans.
