Can Peptides Protect the Brain From Vascular Damage?

Can peptide biology protect the brain from vascular damage? John follows a question that started with Vesugen into the biology of vascular cognitive impairment—endothelial dysfunction, hypoperfusion, blood-brain-barrier injury, mitochondrial stress, inflammation and neuronal damage. The episode maps Cerebrolysin, SS-31/elamipretide, ARA-290/cibinetide, Semax, Vesugen and GLP-1 receptor agonists onto different points in that cascade, then asks the question that matters: what does the human evidence actually support? Cerebrolysin provides the biggest surprise, with randomized vascular-dementia trials—but still low-certainty evidence. Educational only; not medical advice.
