SARS-CoV-2 and other enveloped viruses are in fact extracellular vesicles. They borrow the host cell's machinery to wrap themselves in a lipid membrane, which protects them in circulation and hides them to an extent from the immune system.
It does have proteins in its surface, though, which interact with proteins on the surface of target cells and allow it to get in. Fighting off Covid-19 involves the immune system recognizing those surface proteins and making antibodies to block them. And then the immune system can kill the viruses tagged with those antibodies.
This is not a very informative presentation.what interests people is, if the analysis e.g. of the RNA contained in such vescicles can reveal the presence of a determinate genetic disease or of determinated cancer cells, and if those markers appear long before the patient notices particular symptomes suspect of cancer origin.
You might want to take a look at these other webinars from the series. They address, for particular diseases, research to identify exRNA in vesicles that act as early biomarkers of disease. ruclips.net/video/mJJKTp5NEbQ/видео.html ruclips.net/video/tmkEB8YBHBQ/видео.html ruclips.net/video/EA1gV9iTQto/видео.html ruclips.net/video/-VJj1tkJOsE/видео.html

Is covid-19 one in the same as an exosome? Asking for a friend.
Is it??

(SARS-CoV-2 is the virus and Covid-19 is the disease it causes, like HIV causes AIDS.)
@@extracellularrnacommunicat5827 That sounds interesting. Can you do an informative video to that specific topic please?
“Ejaculate from a person who has given birth to children” what?
🤪
