The small size of the coronavirus often makes it difficult to capture its particles in images. However, using an electron microscope and coloring the images, the US National Institute of Allergy and Infectious Diseases (NIAID) managed to show them from a new perspective.
These images show what the virus looks like when it invades and interacts with human cells, forcing them to reproduce their genetic material within the human body. In particular, you can see the precise moment in which the SARS-CoV-2 particles surround the cells of a patient infected by the virus and start the apoptosis process: this consists of the self-destruction to which the virus forces the virus to the cells.
In this way, the virus, after adhering to the cells thanks to the spike-shaped proteins that cover its particles, achieves alter natural function that human cells have so that they are dedicated to helping the virus to multiply, creating copies of its ribonucleic acid constantly.
In the words of Vanderbilt University doctor of infectious diseases specialist William Schaffner, the genetic material “hijacks the metabolism of the cell and effectively says, ‘Don’t do your usual job. Your job now is to help me multiply.'” just like appointment The New York Times.
Previously, in addition to NIAID itself, Russian and Chinese scientists also obtained photographs of the virus, thanks to which it can already be determined that the microorganism has the ability to change its shape based on environmental conditions.
