A single enzyme shown to be a primary predictor of COVID-19 severity
Scientists from the University of Arizona, Stony Brook University, and Wake Forest University School of Medicine have reported findings that the enzyme phospholipase A2 group IIA, referred to as sPLA2-IIA, may be the most important factor in predicting which patients with severe COVID-19 eventually succumb to the virus.
The sPLA2-IIA enzyme is similar to one contained in rattlesnake neurotoxin as it can destroy cell membranes and is usually found in low concentrations in healthy individuals since it is a key defense against bacterial infection.
At high levels, the activated enzyme can shred membranes of vital organs, as Floyd Chilton, senior author on the paper and director of the University of Arizona Precision Nutrition and Wellness Initiative describes:
It's a bell-shaped curve of disease resistance versus host tolerance. In other words, this enzyme is trying to kill the virus, but at a certain point it is released in such high amounts that things head in a really bad direction, destroying the patient's cell membranes and thereby contributing to multiple organ failures and death."

The sPLA2-IIA enzyme is very similar to an enzyme in rattlesnake venom.

Because it is a neurotoxin?

Or is it similar in other ways as well? Because there are quite a few neurotoxic enzymes and they really aren't all the same. But maybe one that works for snakebite would work for them all.
But who knows? It could happen. Maybe you could look into the actual enzymes involved rather than relying on a media article. Because, in general, the media are not very good at science. Would you agree?

This is very interesting …. I drink Greek mountain tea regularly …. Sideritis syriaca . I have given this tea to several friends of mine in the past 2 years who have been really sick . Not sure if with covid or not , but bed ridden sick . And in 2 days of drinking the tea a few cups a day , they were fine . …I’m not saying this will kill corona virus or keep you from getting it , but it seems to be a very beneficial tea .

UArizona researchers said they found an enzyme which may help drive COVID-19 severe illnesses and death and it's similar to an enzyme found in rattlesnake venom.
The study made a big discovery of two changing molecule patterns in severely ill COVID-19 patients and those dying from the disease, and that has changed things for researchers. "One we expected, which was energy dysfunction, but a second we didn't expect. And the second we didn't expect were products of this enzyme," said University of Arizona professor Floyd Chilton.
Chilton is part of a study by multiple universities just published in the Journal of Clinical Investigation that found in extremely ill COVID-19 patients, a very similar enzyme that's found in rattlesnake venom was found in these patients, and at astronomical levels that could be causing the death.
"We saw the highest levels of this enzyme we've ever seen in humans and those patients died from the disease," Chilton said. "It's very similar to the rattlesnake and it has many similar properties and much of the biology is the same."
Chilton said normally in humans, this enzyme actually fights off infection, but over their year and a half long study, they found in the second half of the COVID-19 infection in severely ill people, the enzyme was doing a 180 and attacking the body instead. "It's wiping the organs out, participating in multiple organ failure," Chilton said.
This insight could save lives because there are inhibitors for rattlesnake bites that stop the venom from continuing a chemical reaction in the body. In theory, that could be applied to this enzyme with COVID-19 too.
