NewsTiny antibody has big impact on deadly viruses
Researchers have discovered a strategy to neutralise two lethal viruses for which there is currently no approved vaccine or cure. The team identified the first ever nanobody to work against Nipah and Hendra, henipaviruses which have jumped from animals to people.

NewsResearchers find compound that inhibits cutaneous HPVs
Researchers have identified a promising new compound that inhibits cutaneous HPV. In lab studies, the compound inhibited viral replication genes in cutaneous HPVs without damaging host cells.

NewsLow dose of hydroxychloroquine is associated with reduced COVID-19 mortality: study
A new study provides observational evidence that low-dose hydroxychloroquine is associated with reduced COVID-19 mortality in hospitalized patients, particularly those with severe illness, when administered within the first week of symptoms.

NewsScientists find flawed data in recent study relevant to coronavirus antiviral development
A new study shows why scientists still don’t know how the NiRAN domain works. The findings could have sweeping implications for drug developers already working to design antivirals based on flawed assumptions, and underscore the importance of rigorous validation.

NewsT cells take aim at Chikungunya virus
A new study offers the first-ever map of which parts of Chikungunya virus trigger the strongest response from the body’s T cells, bringing researchers closer to developing Chikungunya vaccines or therapies that harness T cells to strike specific targets to halt infection.

NewsHep E virus can live out entire life cycle in kidney cells
Scientists have succeeded in proving in cell culture that hepatitis E viruses can infect kidney cells and can multiply with their help. The entire replication cycle of the virus takes place in kidney cells in the same way as in liver cells, their study shows.

NewsThe gut’s secret weapon: viruses that heal
A comprehensive new review reveals how gut viruses interact with gut bacteria and host immunity, highlighting their roles in conditions like inflammatory bowel disease, colorectal cancer, and C. difficile infection. The findings offer a compelling case for harnessing the virome in novel therapies to reshape gut ecology and restore health.

NewsNovel flu vaccine adjuvant improves protection against influenza viruses, study finds
Influenza hemagglutinin subunit vaccines are more effective and offer better cross protection against various influenza virus challenges when combined with a mucosal adjuvant that enhances the body’s immune response, according to a study.
-
NewsResearch suppresses coronavirus by targeting Mac1
A new study details the vulnerability of coronaviruses to inhibitors of a small protein domain called Mac1, or the “macrodomain,” found in all coronaviruses such as SARS-CoV-2 and MERS-CoV.

NewsWith AI, researchers find increasing immune evasion in H5N1
A new analysis suggests that the H5N1 avian influenza virus is evolving clever strategies. Using artificial intelligence tools, researchers analyzed thousands of viral proteins and found that their bonds to protective antibodies have weakened over time.

NewsStudy links influenza A viral infection to microbiome, brain gene expression changes
Infection with influenza A is found to be associated with disruptions in newborn piglets’ nasal and gut microbiomes and with potentially detrimental changes in gene activity in the hippocampus, a brain structure that plays a central role in learning and memory.
-
NewsSupercharged HIV vaccine could offer strong protection with just one dose
Researchers have shown that they can generate a strong immune response to HIV with just one vaccine dose, by adding two powerful adjuvants — materials that help stimulate the immune system.
-
NewsVaccine disguised as a virus tricks the body into stronger immunity
A simple addition to mRNA vaccines can significantly enhance their effectiveness. Scientists have shown that mice develop a stronger and longer-lasting immune response when the mRNA vaccine is disguised as virus-like particles.
-
NewsHerpes virus plays interior designer with human DNA
Researchers have discovered the cold sore virus reshapes the human genome’s architecture, rearranging its shape in three-dimensional space so that HSV-1 can access host genes most useful for its ability to reproduce.
