Animal and insect invasions could shed light on COVID-19 transmission

Invasions by alien insect and animal species have much in common with outbreaks of infectious diseases and could tell us a great deal about how pandemics spread, according to a research paper published today.

Researchers discover the second possible effective mechanism of remdesivir

The virostatic agent remdesivir was developed to disrupt an important step in the propagation of RNA viruses, to which SARS-CoV-2 also belongs: the reproduction of the virus's own genetic material. This is present as RNA matrices with which the host cell directly produces virus proteins.

Natural products a rich source for novel antiviral compounds

In a recent review in the journal Viruses, researchers look at natural products that can be identified as potential alternative antiviral agents. The reviewers discussed the antiviral activities of several natural products towards DNA and RNA viruses with an analytical approach. The researchers detailed the cellular/viral targets of the active molecules and their impact on the infection and viral replication cycle.

Host cell transmembrane protein MARCH8 targets lysine residues to inhibit SARS-CoV-2 and other viruses

A new study deals with the inhibitory activity of a membrane protein that has broad-spectrum activity against multiple viruses, showing that this is due to its effect on cytoplasmic lysine residue incorporation into replicating virions.

U.S. Congress has clear opportunity to supercharge global health R&D, shows report

The U.S. Congress and Biden-Harris administration have a clear opportunity to supercharge global health research and development (R&D) in the wake of a pandemic that has revealed both the sector's chronic neglect and amazing potential.

New SARS-CoV-2 vaccine candidate produces strong immune response, prevents SARS-CoV-2 infection

A new SARS-CoV-2 vaccine candidate, developed by giving a key protein's gene a ride into the body while encased in a measles vaccine, has been shown to produce a strong immune response and prevent SARS-CoV-2 infection and lung disease in multiple animal studies.

A machine-learning approach to track how yellow fever mosquito moves through the environment

The yellow fever mosquito (Aedes aegypti) is a main vector of deadly diseases like dengue fever, chikungunya, and the Zika virus, which result in hundreds of thousands of deaths worldwide each year.

Researchers develop models to predict epidemics of yellow fever, other mosquito-borne diseases

Yellow fever was the first human disease to have a licensed vaccine and has long been considered important to an understanding of how epidemics happen and should be combated.

Evolution of the spike gene of SARS-CoV-2 for human adaptation

Researchers have found a 96% similarity in nucleotide sequence between bat coronavirus (RaTG13), isolated from Rhinolophus affinis bats in China in 2013, and SARS-CoV-2 and ~97% amino acid similarity with the Spike (S) protein. This S protein performs two essential roles, i.e., mediates receptor-binding and membrane fusion. Hence, spike protein is regarded as a key coronavirus determinant of host tropism.

Researchers develop prototype COVID-19 vaccine using DNA vaccine platform

It is necessary to develop additional COVID-19 vaccines, as different vaccine approaches have their advantages and disadvantages and may work synergistically.

Researchers identify key gene necessary for cells to consume and destroy viruses

A team led by UT Southwestern researchers has identified a key gene necessary for cells to consume and destroy viruses. The findings, reported online today in Nature, could lead to ways to manipulate this process to improve the immune system's ability to combat viral infections, such as those fueling the ongoing COVID-19 pandemic.

Higher risk of West Nile virus infection in low-income urban neighborhoods in Baltimore

In Baltimore, Maryland, people living in low-income urban neighborhoods are more at risk of contracting West Nile virus, a mosquito-borne disease, than people living in more affluent neighborhoods. So reports a new study published in the Journal of Medical Entomology.

Chikungunya can infect central nervous system and impair cognitive, motor functions

A study conducted by an international team of researchers with FAPESP's support shows that infection by chikungunya virus can produce even more severe manifestations than the typical symptoms of the disease, such as acute fever, headache, rash, and intense joint and muscle pain.

Antiviral inhibitor DDX42 shows broad activity against Chikungunya, HIV and SARS-CoV-2

By exploiting type 1 interferon's ability to foster an antagonistic cellular environment for viral replication, a research group from France pinpointed DEAD-box RNA helicase DDX42 as an intrinsic inhibitor of HIV, but also other pathogenic viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Chikungunya virus.
