Oxford scientists reveal how viruses self-assemble without a blueprint

Scientists at the University of Oxford have directly observed virus-like particles assembling themselves one molecule at a time, revealing a simple yet precise process behind the formation of complex viral structures, ScienceDaily Health reported.

The researchers found that viral assembly involves proteins forming weak, reversible connections initially, allowing trial and error until stable closed structures emerge. These stable arrangements act as checkpoints that guide the assembly along successful pathways.

A critical milestone in this process is the formation of a closed pentagonal ring made of five larger protein building blocks. This structure is the first to achieve high stability and accelerates subsequent growth stages of the viral particle.

Understanding these assembly steps could lead to new antiviral drugs and improved vaccines by targeting and disrupting the formation of protective viral shells, the study published in Nature suggests.

The discovery offers a detailed look at a process that had been difficult to observe directly and may open avenues for medical treatments that interfere with virus construction.
