Dust mite allergens activate well-known inflammatory factor to trigger allergies

A research team at MedUni Vienna, working in cooperation with the Johns Hopkins University in Baltimore, has discovered how certain dust mite allergens activate a well-known inflammatory factor - serum amyloid A protein -and can thus "trim" the lung tissue "in the direction of allergy".

UAH researchers assess treatment efficacy of naturally occurring compounds against COVID-19

The Baudry Lab at The University of Alabama in Huntsville has identified 125 naturally occurring compounds that have a computational potential for efficacy against the COVID-19 virus from the first batch of 50,000 rapidly assessed by a supercomputer.

Researchers produce first fully-glycosylated full-length SARS-CoV-2 spike protein models

The virus SARS coronavirus 2 (SARS-CoV-2) is the known cause of coronavirus disease 2019 (COVID-19). The "spike" or S protein facilitates viral entry into host cells.

Synthetic peptide could be an effective COVID-19 treatment and SARS-CoV-2 vaccine

Ligandal, one of the world’s leading genetic medicine companies, has modeled a synthetic peptide that could be an effective COVID-19 treatment and SARS-CoV-2 vaccine.

Massive proteomics investigation of COVID-19 infection

Researchers from Germany and Switzerland revealed functional effects of individual severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) proteins on cellular level after infection. They placed the findings into the context of host signaling pathways in order to identify vulnerable parts of the virus amenable to treatment. The study is currently available on the bioRxiv preprint server.

A highly sensitive and specific antibody test for COVID-19

A new proof-of-concept study by UK researchers, currently available on the medRxiv* preprint server, describes the development of an enzyme-linked immunosorbent assay that can be used when lower levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) specific-antibodies are present in serum and saliva samples.

Research explores the biophysical behavior of SARS-CoV-2 nucleocapsid protein

In a groundbreaking paper currently available on the bioRxiv* preprint server, the researchers from the Washington University School of Medicine and Stony Brook University showed how nucleocapsid protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is dynamic, disordered and phase separates with RNA – informing, in turn, the discovery of drugs that disrupt viral packaging.

Interesting study on which species may be infected by SARS-CoV-2

The team from the University of Cambridge and the Pirbright Institute found that the Spike protein on SARS-CoV-2 engages with the host cell receptor angiotensin-converting enzyme 2 (ACE2) across a wide range of animals, even though the Spike binding site shows a between-species variation in its amino acid composition.

Promising candidate monoclonal antibodies show "exquisite potency" against SAR-CoV-2

Researchers at Columbia University, Dana-Farber Cancer Institute, and the National Institutes of Health have identified and characterized a range of monoclonal antibodies that potently neutralize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Study takes new treatment approach for blood cancer

In an effort to improve the survival of patients with myeloproliferative neoplasms, a type of leukemia, researchers inhibited a specific protein (alpha5beta1 integrin) to decrease the number of large bone marrow cells (megakaryocytes) in an experimental model.

Unexpected discovery helps explain fundamental mystery about how muscles work

Researchers at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association developed a mouse model that enables them to look inside a working muscle and identify the proteins that allow the sarcomere to contract, relax, communicate its energy needs, and adapt to exercise.

PIM profile may help identify proteins expressed by viruses transmitted by Aedes aegypti mosquitos

The life span of the Aedes aegypti mosquito ranges from two to four weeks depending on environmental conditions, during which the female lays about one thousand eggs in water-filled containers close to human environments, because it needs human blood in order to reproduce and to complete its life cycle.

Brain-transportable soy derivate reduces memory degradation in mice

In a study that could help one day give a literal meaning to food for thought, researchers from Kyushu University in Japan have reported that a protein fragment that makes its way into the brain after being ingested can reduce memory degradation in mice treated to simulate Alzheimer's disease.

Killifish model helps unravel molecular events that lead to loss of protein homeostasis during brain aging

Aging is the main risk factor for dementia and Parkinson's disease. As age progresses, toxic protein aggregates pile up in the brain and impair neuronal function.

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.

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.

Research team shines new light on inflammatory cell death regulator

Walter and Eliza Hall Institute researchers have made significant advances in understanding the inflammatory cell death regulatory protein MLKL and its role in disease.

Viruses can steal genetic signals from hosts to expand their own genomes

Like a scene out of "Invasion of the Body Snatchers," a virus infects a host and converts it into a factory for making more copies of itself.

Blood types and COVID-19 risk confirmed

Blood type may play a pivotal role in driving disease severity among coronavirus disease (COVID-19) patients. Genetic analysis of COVID-19 patients has shown that people with blood type O seemed to be protected against severe disease. In contrast, those with blood type A may experience complications tied to the viral infection.

Widespread testing could help stop the spread of COVID-19

The world is now in the grips of a historic pandemic. The death toll from the novel coronavirus has climbed to more than 117,000 in the United States and 448,000 around the world.
