Furthermore, it is likely that another key peptidase, Nln is also affected in COVID‐19 patients, since it is the only other enzyme that inactivates all three peptides (bradykinin, substance P, and neurotensin) and has been associated with stroke, brain edema formation, increased brain microvascular permeability and neurogenic inflammation (part of COVID‐19‐associated outcomes). Here, NTS is linked to stroke disorder.
