Title Heat-treated Lactobacillus crispatus KT strains reduce allergic symptoms in mice.
Journal J. Agric. Food Chem.
Abstract In the current study, we investigated the effects of heat-treated Lactobacillus crispatus KT strains on allergic response in mice. We found that the number of interferon (IFN)-gamma(+)CD4(+) cells was higher in C3H/HeN mouse spleen cultures incubated with L. crispatus KT strains than in those cultured with Lactobacillus JCM type cultures. The serum immunoglobulin E levels in NC/Nga mice that were administered KT strains were lower than those in the mice that were not given any bacterium. The ratio of spleen IFN-gamma(+)CD4(+)/interleukin-4(+)CD4(+) was highest in mice given L. crispatus KT-11. L. crispatus KT-11 also increased the expression of Toll-like receptor (TLR) 2, nucleotide-binding oligomerization domain (NOD) 1, and NOD2 in C3H/HeN mouse Peyer's patch cells. These results suggest that the L. crispatus KT-11 strain reduces allergic symptoms in NC/Nga mice via the adjustment of the type 1 helper T cell and type 2 helper T cell balance via TLR2, NOD1, and NOD2.
