Ferritin as a biomarker of aging: geroprotective peptides of standardized human placental hydrolysate. A review

Ferritin, an iron transport protein, is an acute phase protein of inflammation and oxidative stress (OS), a biomarker of cytolysis and ferroptosis. Inflammation, OS and iron overload are characteristic processes of the pathophysiology of aging. Human placental hydrolysates (HPHs) are promising hepatoprotective agents for anti-aging therapy. The goal of the team of authors was to systematize data on ferritin as a marker of aging and to identify peptides that counteract the aging pathophysiology, including through the regulation of iron and ferritin metabolism, in the HPH Laennec (manufactured by Japan Bioproducts). The results of basic and clinical studies confirm the above relationships and indicate that blood ferritin levels characterize the chronological and biological aging of the human body.
