New Research Shed Light On Strange, Giant Viruses

Recently, giant viruses have been discovered in lots of the world’s oddest regions, from unknown areas below the Antarctic ice to the thawing permafrost of Siberia. But, we should not worry yet, according to scientists, because now it’s all SF. How did such strange yet captivating enormous microbes emerge? In new research, scientists might finally get close to the truth and set a new ground of study.

New Research on Giant Viruses

A team of scientists from the Michigan State University enrolled in what seems one of the most challenging missions so far: finding more information about the giant viruses. They analyzed current data and realized a model for studying the viruses. Their work is the first to discover and characterize lots of vital proteins responsible for the appearance of infections.

Giant viruses are more than 300 nanometers in size, and they can last for millennia. The rhinovirus (common cold), for example, is almost 30 nanometers, making those gargantuan viruses exceedingly terrible. Scientists found in Siberia that the viruses are so dangerous, having the ability to infect even after 30,000 years in permafrost. How could such a thing be possible?

The exterior layers (capsids) are rugged and can resist harsh environments and conditions, shielding the viral genome inside. The capsids of the species examined in this research, the mimivirus, Samba virus, Antarctica virus, and Tupanviruses, are icosahedral, similar to a twenty-sided die. These species also posses a unique mechanism for launching their viral genome. During the research, lots of roadblocks required to be discussed. First, due to their size, the monstrous viruses are challenging to image. Other studies relied on discovering the “one-in-a-million” virus in the accurate state of infection.

Simulating the Action of Viruses

To find some answers, researchers developed a new way of mimicking infection phases. Utilizing the university’s new Cryo-Electron Microscopy and the Scanning Electron Microscope, the team analyzed different species to an array of severe chemical and environmental treatments made to simulate conditions a virus might encounter during the infection stage.

The results unveiled three environmental states that successfully produced the stargate opening: high temperature, high salt, and low pH. Moreover, each state produced a distinct phase of infection. “We identified key proteins released during the initial stages of infection responsible for helping mediate the process and complete the viral takeover,” stated Kristin Parent, associate professor of Biochemistry and Molecular Biology at MSU.

With the ability to consistently redevelop different phases of infection, the scientists analyzed the proteins discharged by giant viruses during the first stage. Proteins act as mechanics, managing the many biological conditions needed for a virus to infect and destroy a cell’s conceptive skills to make copies of itself.
