Few viruses use 'clever decoy' strategy to evade immune system: Study

While coronavirus continues to spre across globe, New Zealand scientists recently discovered more about how viruses operate and can eve immune system. According to a study published in journal mBio, research team said that y used same technique to investigate changes in cells infected with SARS-CoV-2 in a bid to learn more about dely virus which has claimed over 775,000 lives globally. 

researches looked specifically at Oryctes rhiceros nudivirus (OrNV) virus, which is an important biocontrol nt against coconut rhiceros beetle. team said that it is a devastating pest for coconut and oil palm trees in Souast Asia and Pacific Islands. As per study, researchers found that virus used a ‘decoy’ strategy to eve immune system. y also explained that recent findings are a small step in bid to better understand infectious diseases like COVID-19.

scientist used electron microscopy to investigate cellular changes occurring during nudivirus infection. y found a unique mechanism for how virus work, team ted that disease acquires a membrane inside nucleus of infected cell and it gets fully equipped to infect new cells at precise location. 

study revealed that process is in contrast with or enveloped viruses, including coronavirus, which is also an enveloped virus. team said that viruses derive ir enveloped membrane from or cellular compartments. Dr Mihnea Bostina, study author, said that virus gets fully assembled, it used a ‘clever tactic’ of passing through different environments, packed inside various membrane structures until it gets released at cellular membrane.

‘Clever strategy’ 

Ar study researcher, Sai Velamoor, said that aforementioned strategy implies that many of viruses released by infected cells will be enclosed in a cellular membrane while travelling inside infected organism. 

Velamoor ted, “This means y will be missed by immune system and y can use this membrane decoy to penetrate any or of cells, without need of a virus-specific receptor”.

She furr ded, ”It shows for very first time a clever strategy available to insect viruses. It will be interesting to find in what measure or s of viruses - like ones infecting humans - are also capable of carrying out a similar process”. 

recent research demonstrated ar manner in which viruses are capable of hijacking infected cells. team revealed that it alerts scientists to vel mechanism of viral transmission. Furrmore, authors said that viruses will never cease to amaze researchers with ir ‘indefatigable arsenal of tricks’. y also ded that only by studying viruses, researchers can be prepared to equately respond when y infect.
