The Renin-Angiotensin-Aldosterone System (RAAS) #peptides #podcast

About this video

This short clip expands the renin-angiotensin-aldosterone system beyond blood pressure. Seeds argues RAAS receptors are present in many tissues, including fibroblasts where they influence fibrous tissue accumulation, and that the system is deeply involved in metabolism, immunity and neurocognition. He contrasts ARBs with ACE inhibitors, claiming some ARBs cross the blood-brain barrier and can act on receptors on microglia in the brain while ACE inhibitors do not in the same way. The point of the clip is educational: understanding these pathways, Seeds argues, explains why two pressure drug classes can have different wider effects.

Key takeaways

• RAAS should be understood as a body-wide signaling system, not only a pressure system
• Seeds claims tissue RAAS receptors help explain fibrosis, metabolic and immune effects
• Brain penetration is presented as a meaningful difference between some ARBs and ACE inhibitors
• Pathway knowledge is framed as the basis for smarter drug selection
• Cognition is treated as part of cardiovascular physiology, not separate from it
