It has been 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 the Institut Pasteur and CNRS have elucidated the role of a molecule in the blood (Gdf11) in anti-aging In a mouse model, they showed that the molecule (Gdf11) 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 The scientists of I nstitut Pasteur / CNRS put forward the theory that because both heat restriction and young blood supplement can effectively revitalize organs, they are likely to have some common mechanisms The researchers studied the Gdf11 protein, which belongs to the GDF (growth differentiation factor) protein family and is involved in embryonic development Gdf11 is well known for its ability to rejuvenate the aging brain Next, researchers will confirm this theory by studying adiponectin, a hormone secreted by fat 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.
