“Absolutely yes, I think a major component of Long Covid is neurological, and by neurological I don’t mean only central neurological, peripheral neurological….”

“They found that the strongest signal was coming from serotonin. Peripheral serotonin levels were very similar between those who are acutely active with Covid and those who had Long Covid and much lower than those who had recovered from Covid and did not have persistent symptoms.”

“So the hypothesis that I had here was that Long Covid patients seem to have this constellation of symptoms that were resembling some kind of immune disturbance. So I thought that if we actually looked at underlying T cell responses to the virus, we could find a pattern that differentiated these patients from those who completely recovered after. As an immunologist, it kind of screamed let's look at the T cell response.”
