Abstract
BACKGROUND
Probiotics could be beneficial to health and some of them have shown to modulate immune responses.
AIM
The aim of this study is to investigate if the probiotic strains including Lactobacillus and Pediococcus strains are able to alleviate allergic reactions in an ovalbumin-induced airway allergy model.
METHODS
Lactobacillus multi-species preparation (LMP) was gavaged to BALB/c for total six weeks and BALB/c was challenged with ovalbumin in the last two weeks. A barometric whole-body plethysmography was used to assess enhanced pause (Penh) of airway hyperreactivity (AHR). Immunoglobulins (Ig) such as IgE, IgG1, IgG2a and cytokines such as IL-12, IFN-γ, IL-4, IL-5, TNF-α and IL-13 in bronchoalveolar lavage fluid were assayed using ELISA kits.
RESULTS
The results showed this LMP significantly reduced Th2 cytokines and enhanced Th1 cytokines production. OVA-specific IgE and IgG1 was lower in the probiotics-treated mice whereas IgG2a was increased. Most importantly, this murine model showed LMP supplementation significantly reduced AHR.
CONCLUSIONS
Overall, this Lactobacillus multi-species preparation seemed to suppress OVA-sensitized airway hyperreactivity, thus serving as a possible candidate for therapeutic uses for allergic airway symptoms.
