A Systems-Level Immune-Regenerative Response Induced by Localized Mechanical Stimulation in Humans

This is a preprint and has not been peer-reviewed. This study presents the first evidence of a latent physiological system in humans—termed the Emergency Regenerative Defense Program (ERDP)—that is rapidly activated by mild mechanical stimulation and simultaneously induces immune, regenerative, and metabolic responses. Using a specific noninvasive stimulus (RE-regenerative acupuncture), we collected peripheral blood samples before, during, and up to two hours after stimulation. Through flow cytometry, LC-MS/MS-based proteomics of plasma and exosomes, and microscopy, we observed dynamic shifts in immune cell populations, mobilization of stem cells, and the emergence or disappearance of specific plasma proteins and exosomal contents. Strikingly, several proteins appeared de novo or were lost entirely within minutes—phenomena rarely documented in human physiology. The coordinated activation of innate immunity, adaptive immunity, and regenerative pathways within two hours suggests the presence of a previously unrecognized endogenous emergency program. This systemic, nonpharmacologically induced response cannot be fully explained by current immunological or physiological models, and may offer a new framework for understanding acute human repair and defense mechanisms.
