Résumé
Organs and tissues are subjected to numerous alterations during aging, as a result of complex biochemical changes. Aging is certainly associated with the accumulation of "antiaging" and "proaging" factors in the systemic circulation. The effects of young blood on rejuvenation of regenerative capacity suggest the existence of multiple "proyouthful" factors, such as growth differentiation factor 11 (GDF11), in the young blood of animals. GDF11 is a member of the transforming growth factor beta (TGFβ) superfamily of cytokines, and appears to be a critical rejuvenation factor in aging organs. In the context of aging, GDF11 promotes vascular and neural plasticity of the central nervous system. Parabiosis, the surgical linking of circulations between old and young mice, was employed to identify GDF11 as an antihypertrophic factor that appears to rejuvenate the aging murine heart. Current theories suggest that GDF11 in young blood has beneficial effects on cognitive and cardiovascular functions and wound healing. The cellular mechanisms of GDF11 in cardiovascular, neurological, skin and skeletal muscle diseases are not clearly defined, but evidence indicates that it may function as a proneurogenic and proangiogenic drug. GDF11 binds and activates specific receptor complexes, which transmit signals by two procedures: the TGFβ-Smad pathway and the bone morphogenic protein (BMP)-Smad pathway. GDF11 is perhaps only the first in a series of circulating molecules that will be found to influence the aging of different tissues, and it may be a potential candidate for therapeutic intervention against angiogenesis-related disorders.
