Removing Harmful Factors in Old Blood Has Age Reversing Effect

Our data demonstrate that a single NBE suffices to meet or exceed the rejuvenative effects of enhancing muscle repair, reducing liver adiposity and fibrosis, and increasing hippocampal neurogenesis in old mice, all the key outcomes seen after blood heterochronicity.

Aging Journal – Rejuvenation of three germ layers tissues by exchanging old blood plasma with saline-albumin Abstract Heterochronic blood sharing rejuvenates old tissues, and most of the studies on how this works focus on young plasma, its fractions, and a few youthful systemic candidates.

Researchers have found that age-reversing effects can be achieved by simply diluting the blood plasma of old mice — no young blood needed.

Comparative proteomic analysis on serum from NBE, and from a similar human clinical procedure of therapeutic plasma exchange (TPE), revealed a molecular re-setting of the systemic signaling milieu, interestingly, elevating the levels of some proteins, which broadly coordinate tissue maintenance and repair and promote immune responses.
