ACE2 and asthma: The expression of cell surface enzyme angiotensin-2 converting enzyme (ACE-2), which binds to SARS-CoV-2 spike protein promoting its internalization into target cells [4,5], was probed in the nasal epithelium among a cohort of 305 patients aged 4 to 60 years: adjusting for sex and asthma condition, ACE-2 expression was found to increase with age, offering a fertile ground for the high loads of SARS-CoV-2 virions present in the nasal cavity [6].
