As noted here, joining the circulatory systems of an old and young mouse results in some degree of rejuvenation in the old mouse. Where brain function is improved, researchers are interested in how changes in the blood signaling environment might be involved. While research initially focused on factors in young blood that are reduced in old blood, it is increasingly thought that the important mechanism is a dilution of harmful factors carried in the old bloodstream. This has led to a few studies of plasma transfer and dilution in humans, and <a href="https://www.fightaging.org/a…
