TMPRSS2 and infection: Potential AVP therapeutic targets can befound on the virus (such as E-protein and S-protein, which preventviral binding) or on the host cell surface, such as angiotensin-convertingenzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2).11 This Review summarizes a few recent studieson peptides for their diverse application in treating infections anddiseases.
