In the search for a rapid, easy way to identify drugs to fight SARS-CoV-2, researchers from across the US came together to develop and apply a high-throughput ADP-ribosylhydrolase assay, ADPr-Glo. Here, Dr Veronica Busa and Dr Anthony Leung from Johns Hopkins University describe the ADPr-Glo assay and how it can be…
Dr Pushpanathan Muthuirulan explores why messenger RNA (mRNA) is advantageous for vaccine development and how the COVID-19 pandemic has accelerated its progress within the pharmaceutical industry.
Neutralisation resistance generated by Spike (S) protein mutations in Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) poses a challenge to antibody therapies for COVID-19. Antibody cocktails targeting the S protein receptor binding domain (RBD) are one way to avoid viral neutralisation escape, however only certain antibody combinations are currently effective.…
Researchers have found that a metabolite of remdesivir potentially targets a SARS-CoV-2 protein involved in suppressing the host cell's defence response.
Researchers have used cryo-EM to show that a new nanobody cocktail can bind to the S protein of SARS-CoV-2, neutralising the coronavirus.
A candidate vaccine has shown potential against MERS in non-human primates, when administered intradermally.
Recent years have seen an increase in the development of biomaterial and nanoparticle-based vaccine formulations. Sushma Kumari, Sonal Asthana and Kaushik Chatterjee from the Department of Materials Engineering at the Indian Institute of Science discuss why these materials have such high potential in the fight against infectious diseases.
The length of time between the administration of a COVID-19 vaccine and evidence of a robust immune response to Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) means that treatments are still required. In this article, Sheraz Gul and Alp Tegin Sahin explore the various therapeutic targets that have been identified…
A new study has shown that previous coronavirus infection may contribute to the immune response of patients infected with SARS-CoV-2.
Scientists shows targeting cholesterol or phosphatidylinositol phosphate (PIP) could be a promising strategy to combat multiple coronaviruses.
Results of a recent study by researchers at the University of Bristol indicate neuropilin-1 is an important host factor for SARS-CoV-2 infection. The team suggests that blocking neuropilin-1 may be a valuable therapeutic intervention in the treatment of COVID-19. Nikki Withers spoke to one of the study’s lead investigators, Dr…
Using atomistic simulations, a team has demonstrated how coronavirus Spike proteins move and vibrate to let the virus through cell walls.
A specific furin cleavage motif on the SARS-CoV-2 Spike protein, not present on other coronaviruses (CoVs), could be targeted by novel COVID-19 therapies.
Researchers studying the PLpro binding site of three coronaviruses, including SARS-CoV-2, say the BL2 loop could be targeted by antiviral drugs.
The global network of centers will investigate where pathogens emerge and how they adapt to cause disease in humans, in the hopes of increasing our preparedness for future disease outbreaks.
