摘要：We monitored the impact of selected probiotic strains on the human immune system. 13 strains of lactic acid bacteria ( Lactobacillus acidophilus , Lactobacillus helveticus, Enterococcus faecium , Streptococcus thermophilus , and Propionibacterium freudenreichii subsp . shermanii ), used in the production of functional foods, were tested from the point of view of their ability to stimulate a range of cytokines. The selected cytokines have regulatory properties; they affect the progression of inflammation and the inhibition of inflammatory response, and they play a role in humoral immunity, allergies, and cell-mediated immunity. The tested strains showed a specific interaction with the immune system. It was found that the P. freudenreichii strain showed significant levels of IFN gamma cytokine.
