The relationship between allergic inflammation and gut microbiota has been elucidated, and the effect of probiotics on immune disorders has been studied as well. Identifying the role of probiotics in individual diseases and immune responses and selecting and applying specific microorganisms based on these findings can be an effective strategy for using probiotics. Herein, lactobacilli isolated from kimchi were investigated in depth, focusing on their immune regulatory effects and the mechanisms involved. Lactic acid bacteria (LAB) effectively diminished the increased secretion of T helper 2 cytokines, such as IL‐4, IL‐5, and IL‐13, from ovalbumin (OVA)‐sensitized mouse splenocytes. The gene expression of GATA3, IL‐4, IL‐5, IL‐9, and IL‐13 was confirmed to be regulated by LAB. LAB also suppressed IL‐2 production and STAT5 phosphorylation. An IL‐10‐neutralizing antibody attenuated these effects, indicating that LAB‐induced upregulation of IL‐10 in antigen‐presenting cells was responsible at least partially for the increased IL‐2 production and STAT5 phosphorylation in CD4+ T cells. In conclusion, the current study identified one immunomodulatory mechanism that allows LAB to regulate allergic immune reactions and the potential of LAB from kimchi to modulate various immune reactions.
