Angiotensin Peptides and SARS-CoV-2 Spike Binding
2026-08-17
A 2025 study found that naturally occurring angiotensin fragments can increase SARS-CoV-2 spike protein binding to host receptors, with the strongest enhancement associated with specific N-terminal deletions and angiotensin IV. The work connects renin–angiotensin system peptide processing with viral receptor recognition while emphasizing that binding data alone do not establish effects on infection or disease severity.

Cx43/NF-κB Signaling in AngII Macrophages
2026-08-13
The reference study shows that angiotensin II drives RAW264.7 macrophages toward an M1-like inflammatory phenotype through a connexin 43–NF-κB p65 signaling axis. By combining Cx43 inhibition with molecular, cytokine, and phenotypic assays, the work positions Cx43 as a mechanistic regulator of macrophage activation rather than a passive marker of cardiovascular inflammation.

Cx43/NF-κB Signaling in AngII Macrophage Polarization
2026-08-12
The reference study identifies connexin 43 and NF-κB p65 as a linked signaling axis through which angiotensin II drives RAW264.7 macrophages toward a pro-inflammatory M1 phenotype. By combining inflammatory-marker profiling with pharmacological inhibition, it provides a mechanistic framework for studying Cx43-dependent macrophage activation while also highlighting the need to distinguish hemichannel effects from broader connexin biology.
