Cell-mediated and humoral immune responses are attenuated with aging. Intracellular glutathione (GSH) levels also decrease with aging. Previously, we have reported that combined administration of (L)-cystine and (L)-theanine enhances antigen-specific IgG production, partly through augmentation of GSH levels and T helper 2-mediated responses in 12-week-old mice. These findings suggest that combined administration of (L)-cystine and (L)-theanine to aged mice improves immune responses via increase… CONTINUE READING
