Mechanism of ActionThymosin Alpha-1 modulates T-cell function, enhances dendritic cell maturation, and promotes Th1 immune responses. It increases IL-2, interferon-alpha, and interferon-gamma production while reducing inflammatory cytokines.Thymalin contains peptides that regulate thymic function and T-cell development. It restores age-related immune decline, normalizes thymic hormone levels, and has demonstrated effects on longevity markers in studies.
