It is found that a molecule (Gdf11) in the blood plays a role in delaying aging

Recently, published in the latest issue of aging cell in 2019, researchers from Pasteur Institute and CNRS have clarified the role of a molecule in the blood (Gdf11) in anti-aging In a mouse model, they showed that the molecule had similar benefits to calorie restriction In previous studies using mouse models, scientists have observed that injecting blood into the brain of young mice can rejuvenate the blood vessels in the brain of the old mice, thus improving cerebral blood flow, as well as neurogenesis and cognitive ability Scientists from Institut Pasteur / CNRS have proposed the theory that since both heat restriction and replenishment of young blood can effectively rejuvenate organs, they are likely to have some common mechanisms Scientists focused on the study of Gdf11 protein, which belongs to the GDF (growth differentiation factor) protein family and participates in the process of embryonic development Gdf11 is well known for its ability to rejuvenate the aging brain The authors will confirm this theory by studying adiponectin, a hormone secreted by adipose tissue that causes weight loss without affecting appetite In calorie restricted animals, the hormone has a high blood level The findings of this study suggest that Gdf11 may contribute to the creation of new neurons in the brain by inducing phenomena similar to reported calorie restriction leading to stimulation of adiponectin and neurogenesis.
