Abstract
Article Highlights: Different components of the renin-angiotensin system are expressed by vascular cells in human pancreatic islets. The islet microvasculature is responsive to vasoactive angiotensin peptides. This pancreatic renin-angiotensin system is targeted upon incubation with a SARS-CoV-2 spike recombinant protein. SARS-CoV-2 spike activates pericytes and constricts capillaries in human islets. Islet vascular dysfunction could contribute to dysglycemia in some patients with COVID-19.
