Researchers designed artificial peptides that can bind to viral proteins, blocking entry into cells and causing viruses to clump together. These 'miniproteins' were found to be thermostable and safe for use in humans, with promising results in lab tests and animal models.
Researchers at Medical University of South Carolina found that blocking the enzyme polymerase reduces the virus's ability to multiply. This discovery exposes an Achilles' heel that could be targeted with a therapeutic. Polymerase is a key tool for DNA replication and repair, making the virus vulnerable to disruption.
A new research project led by Professor Edze Westra aims to uncover the mechanisms of molecular communication in viruses, which coordinate their infections and replicate in infected cells. The team will use a combination of theoretical, experimental, and observational approaches to address key questions about viral communication systems.
Researchers developed artificial Sars-CoV-2 virions to study the spike protein's interaction with host cells and its ability to evade the immune system. By understanding this mechanism, they hope to develop targeted therapies and vaccines.
A team from the Universities of York and Leeds has identified the way viruses like poliovirus and common cold virus assemble infectious copies of their genetic material. The study's findings could lead to the development of drugs that can block viral infections.
Scientists have identified the way viruses like poliovirus and common cold virus 'package' their genetic code, allowing them to infect cells. The discovery opens up possibilities for developing drugs or anti-viral agents that can stop such infections.
A study using cryoEM revealed the structural effect of a human mutation that made us immune to simian immunodeficiency virus (SIV). The mutation disrupted the ability of an SIV protein to bind human proteins, giving humans a grace period of tens to hundreds of thousands of years without the disease. This finding could provide clues for...

The sensor uses artificial intelligence to identify distinct physical features of the virus, making it suitable for point-of-care screening without specialized expertise.
Researchers have developed a novel approach to track HIV infection by identifying individual viral particles associated with infection. The new method reveals that uncoating leading to infection occurs early in the cytoplasm, around 30 minutes after cell fusion.
A new flu vaccine with reduced doses could improve production capacities and increase vaccine availability. The use of whole virion vaccines and aluminium adjuvants may enable significant dose sparing without compromising safety.
Researchers at UMass Medical School have discovered two host cell membrane proteins, SERINC5 and SERINC3, that greatly reduce the virulence of HIV-1 by blocking its ability to infect new cells. This breakthrough offers a promising new anti-retroviral strategy for treating HIV-1 and similar viruses.
Researchers have obtained the first nanometer-resolved image of individual tobacco mosaic virions using low-energy electron holography, a non-destructive single-particle imaging technique.
