Your immune system might recognize COVID-19

Recommended Posts

Still Waters

Eight months ago, the new coronavirus was unknown. But to some of our immune cells, the virus was already something of a familiar foe.

A flurry of recent studies has revealed that a large proportion of the population — 20% to 50% of people in some places — might harbor immunity assassins called T cells that recognize the new coronavirus despite having never encountered it before.

The presence of these T cells has intrigued experts, who said it was too soon to tell whether the cells would play a helpful, harmful or entirely negligible role in the world’s fight against the current coronavirus. But should these so-called cross-reactive T cells exert even a modest influence on the body’s immune response to the new coronavirus, they might make the disease milder — and perhaps partly explain why some people who catch the germ become very sick, while others are dealt only a glancing blow.

What is a T Cell:

"Groups of specific, differentiated T cells have an important role in controlling and shaping the immune response by providing a variety of immune-related functions."

https://en.wikipedia.org/wiki/T_cell

I think the yahoo article is misleading as knowing about T cells and how they work is NOT New.  Even the premise the article writes about is not new.

Yahoo have sourced The New York Times for this article. I didn't use their link because it's a subscription. Other news sites have also reported this sourcing The New York times.

Researchers are eager to understand the history of these T cells, because that might help reveal who is more likely to have them. A growing body of evidence, including data published this week in Science by Dr. Sette and his colleagues, points to common-cold coronaviruses as a potential source.

Still doesn't solve the mystery about what it is that makes SARS-CoV-2 that makes it so problematic in comparison with other SARS-CoV strains...
