Historic firsts in whey protein, glutathione, and the immune system
2008: Gustavo Bounous, Wulf Dröge and colleagues were the first to show in a placebo controlled clinical trial the health benefits of an undenatured whey protein isolate in cancer patients.
"The patients treated with the cysteine-rich protein had a mean increase of 2.5% body weight, whereas casein-treated patients lost 2.6%."
1998: Wulf Dröge and colleagues were the first to discover the age-related decrease in the plasma concentration of cysteine, the limiting precursor of glutathione.
"Our study showed a decrease in the plasma thiol level indicative of an age-dependent shift to a more oxidized condition."
1989: Gustavo Bounous and colleagues were the first to discover that glutathione plays a role in the effect of whey protein on the immune system.
"Enhancement of host humoral immune response is associated with sustained production of splenic glutathione in whey protein fed mice."
1989: Wulf Dröge and colleagues were the first to discover that HIV-infected patients have abnormally low cysteine and glutathione levels.
"Blood plasma from HIV-1-infected persons contains decreased cysteine concentrations. The intracellular glutathione concentration in peripheral blood-mononuclear cells (PBMC) and monocytes from HIV positive persons are also significantly decreased."
1986: Wulf Dröge and colleagues were the first to discover the effect of glutathione on the immune system in a living organism.
"The activation of T lymphocytes in vivo was found to be augmented by glutathione." (Cytotoxic T cells eliminate virus-infected cells in the body, and T cells help B cells to produce a humoral immune response).
1981/1988: Gustavo Bounous and colleagues were the first to discover the effect of a whey protein on the immune system.
"The plaque-forming cell response to sheep red blood cells was found to be enhanced in mice fed a formula diet containing 20g lactalbumin/100 g diet." (The humoral immune response eliminates bacteria in the body).
