Combinations of cereal β-glucans and probiotics can enhance the anti-inflammatory activity on host cells by a synergistic effect / M.P. Arena, P. Russo, V. Capozzi, A. Rascón, G.E. Felis, G. Spano, D. Fiocco. - In: JOURNAL OF FUNCTIONAL FOODS. - ISSN 1756-4646. - 23:(2016 May), pp. 12-23. [10.1016/j.jff.2016.02.015]
Abstract:
The influence of oat and barley β-glucans on some features of diverse probiotic strains was investigated. Neither barley nor oat β-glucans supported the growth of any of the investigated strains when used as the sole carbon source in fermentation media. No protective effect by β-glucans was observed on bacterial survival to in vitro simulation of the human digestive tract. Moreover, the presence of β-glucans did not enhance the ability of probiotic bacteria to adhere on human intestinal cells. The immunomodulatory activities of probiotics, β-glucans, and their combinations were studied and compared in vitro by transcriptional analysis of immune-related genes on LPS-stimulated THP-1 macrophages. Immune modulating properties were evidenced. In particular, mixtures of probiotic microorganisms and barley β-glucans exhibited synergistic effects in modulating the transcriptional level of several immune-related genes, leading to an overall enhanced anti-inflammatory effect. Together, these findings suggest a promising application of probiotic bacteria and β-glucans in the preparation of dietary mixtures presenting health-promoting features such as immunomodulatory properties.
