Dead Cells May Help Viruses Spread, Australian Researchers Discover

Uncovering a New Viral Transmission Route

According to НВ — Техно: On July 19, 2023, scientists from La Trobe University in Australia identified a previously unknown mechanism that viruses can exploit to spread. This process relies on tiny particles called F-ApoEVs, which are left behind after cells undergo programmed death (apoptosis). These particles can then carry viruses to infect neighboring healthy cells. The team used 3D time-lapse imaging and experiments with the influenza virus to make their discovery. It is important to note that these findings are based solely on laboratory experiments.

Why This Discovery Matters

The La Trobe University researchers found that when cells die, they release F-ApoEVs, which can harbor hidden viruses. Lead author Dr. Stephanie Rutter explained:

“The team was already aware of the immune system's role in clearing dead cells from the body, which helps prevent inflammation and autoimmune diseases.” - Dr. Stephanie Rutter

However, the researchers did not anticipate that viruses could hijack this process to cause new infections. Biochemist Ivan Poon added that cell destruction during death was previously thought to be a relatively simple and random event.

This breakthrough opens up new avenues for understanding how viruses spread and could have major implications for future virology research. It highlights the need for further laboratory studies to better grasp the role of F-ApoEVs in infection processes and to explore their potential for developing new antiviral strategies.

This recent discovery sheds light on the complex interactions between viral mechanisms and cellular processes. Understanding how viruses utilize cellular debris for infection could reshape our approach to antiviral strategies.
