What's the science behind Advil "kickstarting" a virus into pneumonia?

From Sauto's Wired article linked above:

The trouble over ibuprofen began March 11, when researchers at University Hospital Basel, in Switzerland, and Aristotle University of Thessaloniki, in Greece, published a letter in The Lancet Respiratory Medicine. The letter reviewed three early sets of case reports from China, covering almost 1,300 patients gravely ill with Covid-19. The letter’s authors observed that significant numbers of those patients had high blood pressure and diabetes, from 12 percent to 30 percent depending on the study, and theorized that higher rates of expression of a particular enzyme, known for short as ACE2, might be raising the risk of coronavirus infection.

ACE2 provides a place on cell surfaces for the coronavirus to attach and enter in order to replicate. High blood pressure and diabetes are treated with drugs that suppress inflammation, called ACE inhibitors; the inhibitors, paradoxically, cause ACE2 to rise. That interaction is where the authors spotted a possible connection between patients experiencing chronic diseases and then becoming infected with Covid-19.

And that’s where ibuprofen entered the unfolding story, too. The over-the-counter drug doesn’t only knock down fever. It also reduces inflammation (the class of drugs it belongs to are known as NSAIDs, non-steroidal anti-inflammatory drugs). That effect, as with the anti-inflammatory drugs given to chronic disease patients, can cause ACE2 to rise.
