Angiotensin III and SARS-CoV-2 Receptor Binding
2026-09-17
The 2025 study by Oliveira and colleagues shows that naturally occurring angiotensin peptides can increase SARS-CoV-2 spike-protein binding to host receptors, with particularly strong effects from N-terminally truncated peptides such as Angiotensin III and Angiotensin IV. Its antibody-based binding experiments provide a mechanistic link between renin–angiotensin signaling and viral receptor engagement, while also emphasizing that the findings require validation in cellular and physiological infection models.
