Hyperbaric oxygen reduces senescent T cells by 37%: scientific confirmation of a rejuvenation mechanism
Original title: La cámara hiperbárica reduce en un 37% las células T senescentes — estudio de replicación lo confirma
A replication study published in Aging confirms the seminal findings of Shamir et al. (2020): sixty sessions of hyperbaric oxygen therapy at 2 ATA significantly reduce CD28null senescent T cells and induce telomere lengthening in peripheral blood lymphocytes. This experimental validation closes a critical gap in understanding immune aging, demonstrating that an accessible and repeatable protocol produces quantifiable molecular changes. For longevity practitioners, the signal is unambiguous: there now exists a demonstrated mechanism to reverse one of the most robust markers of immune senescence, raising an uncomfortable question about why hyperbaric therapy remains peripheral in healthy aging protocols.
