Effect of the oral administration of Lactobacillus brevis subsp. coagulans on interferon-alpha producing capacity in humans.

Abstract

Oral administration of live Labre significantly increased IFN-alpha production in a dose-dependent manner. Labre intake tended to be most beneficial in subjects with initially low levels of IFN-alpha production. Heat-treated Labre did not elicit a response similar to that of the live bacteria.
