Effective, simple, safe self-amplifying RNA vaccines

A recent review paper in the journal Current Opinion in Virology in September 2020 shows how a new generation of RNA vaccines called self-amplifying RNA vaccines are more potent than conventional mRNA vaccines and could hold the key to the global production of cost-effective potent COVID-19 vaccines.

Antibody-mediated platelet death linked to COVID-19 severity

A new study by University of Tuebingen researchers shows the strong association between platelet apoptosis and the thrombotic manifestations that may underlie critical COVID-19 illness.

Important research on SARS-CoV-2 proteins using proximity labeling

A team of Canadian scientists has recently discovered a wide-range interaction between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and host proteins using proximity-dependent biotinylation approaches.

Existing drug masitinib identified as potential inhibitor of SARS-CoV-2

Researchers in the United States have demonstrated that a drug originally developed as a treatment for cancer exhibits antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

COVID-19 patients may experience long-term cardiovascular complications

Researchers at the University of Washington in Seattle have conducted a study suggesting that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can directly infect heart tissue and contribute to whole-organ cardiac dysfunction.

Targeting a key gateway can help treat chronic pain, shows study

Something like a quarter of the world's population suffers from chronic pain at some point. As opposed to acute pain – for example, that feeling after hitting your finger with a hammer – chronic pain may not even have a clear cause, and it can linger for years or lifetimes.

New approach to chronic pain treatment could bring relief

Something like a quarter of the world's population suffers from chronic pain at some point in their lives. As opposed to acute pain - for example, the feeling after hitting your finger with a hammer - chronic pain may not even have a clear cause, and it can linger for years or lifetimes.

New technique enables real-time observation of influenza A hemagglutinin during viral entry

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses.

Membrane nanoparticles acts as a bait to trap SARS-CoV-2

In an exciting new bioRxiv preprint research paper, Chinese researchers describe the development of membrane nanoparticles from ACE2-rich cells with a potent capacity to block the adherence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

SARS-CoV-2 a "swarm" of mutant viruses

In this new study, the virus was serially passaged in independent cell types in a controlled environment. The researchers found that the virus rapidly adapts to the changing conditions in culture by selecting for pre-existing species.

DHODH inhibitor PTC299 shows potential as a COVID-19 therapeutic

As COVID-19 continues to take a heavy toll on human health and life in many parts of the world, there is still no effective antiviral drug or vaccine. This has fueled an intensive search for small molecules and proteins that can inhibit viral entry and replication.

Coronavirus-specific structure in cells may lead to new antiviral strategies

By visualizing coronavirus replication in an infected host cell, researchers may have answered a long-standing question about how newly synthesized coronavirus components are able to be incorporated into fully infectious viruses.

Avidity of binding responsible for cross-neutralization of SARS-CoV-1 and SARS-CoV-2

In a new study published on the preprint server bioRxiv researchers characterized the crystal structure of the antibody-SARS-CoV-2 RBD complex in an attempt to find the epitope and the mechanism that enables cross-neutralization.

Biomedical engineers create artificial organelles to control biological function in cells

Biomedical engineers at Duke University have demonstrated a method for controlling the phase separation of an emerging class of proteins to create artificial membrane-less organelles within human cells.

Study finds synthetic neutralizing/enhancing antibodies to SARS-CoV-2

A new study published on the preprint server bioRxiv in July 2020 reports the discovery of some antibody molecules that have powerful enhancing or neutralizing activity against the virus, in a library of synthetic antibodies. These hold the promise of being useful for the prevention or treatment of this illness.

Vesigen Therapeutics to develop and commercialize novel drug-delivery technologies

Harvard University's Office of Technology Development (OTD) and the Harvard T.H. Chan School of Public Health today announced the launch of Vesigen Therapeutics, a startup company that aims to overcome the challenge of delivering next-generation therapeutics, such as gene-editing complexes, RNA molecules, and other large proteins, to intracellular targets in specific tissues of interest.

Advanced cryo-EM imaging reveals high-resolution structure of viral RNA replication complex

For the first time, scientists at the Morgridge Institute for Research have generated near atomic resolution images of a major viral protein complex responsible for replicating the RNA genome of a member of the positive-strand RNA viruses, the large class of viruses that includes coronaviruses and many other pathogens.

Novel nanospectroscopy measures biomolecular changes induced by drugs in human cells

Synchrotron InfraRed Nanospectroscopy has been used for the first time to measure biomolecular changes induced by a drug (amiodarone) within human cells (macrophages) and localized at 100 nanometre scale, i.e. two orders of magnitude smaller than the IR wavelength used as probe.

Nanotechnology plays major role in COVID-19 vaccine development

From mRNA vaccines entering clinical trials, to peptide-based vaccines and using molecular farming to scale vaccine production, the COVID-19 pandemic is pushing new and emerging nanotechnologies into the frontlines and the headlines.
