AB - Probiotics, regarded as live microorganisms, play important
roles in regulating intestinal inflammatory responses and innate immunity. Although,
intestinal immunmodulation of probiotics have been enormously conducted into
data, the effects of Lact. delbrueckii on jejunum innate immunity are
rarely reported. This study aimed to investigate the effects of Lact. delbrueckii
on serum profiles, jejunum inflammatory cytokines and innate immune-related
genes expression in mouse. A total of 32 Kunming male mice were randomly divided
into four groups and each group were orally administrated with saline normal,
living Lact. delbrueckii, heat-killed Lact. delbrueckii and Spent
Culture Supernatant (SCS). Serum profiles (IL-2, IgG) and jejunum immune-related
gene expression were detected including inflammatory cytokines (INF-γ,
TNF-α, IL-17, IL-13) peneth cell-sepcific gene (cryptdin 1, 4, 5, lysozyme
C, CRS-1C, CRS-4C and sPLA2) and goblet cell-specific gene (mucin-2 and mucin-4).
Compared with control group, orally administrated SCS significantly decreased
(p<0.05) ADG of mice. Orally administrated living and heat-killed Lact.
delbrueckii group significantly increased (p<0.05) serum IL-2 level and
while SCS remarkably decreased (p<0.05) serum IgG level. Meanwhile, oral
administration of living Lact. delbrueckii significantly enhanced (p<0.05)
jejunum inflammatory cytokines (INF-γ, TNF-α, IL-17) expression. SCS
significantly increased (p<0.05) peneth cell-sepcific gene (cryptdin 1, 4,
5 and sPLA2) gene expression. In conclusion, oral administration of Lact.
delbrueckii affects serum profiles and jejunum innate immune-related gene
expression and thereby modulates jejunum innate immunity.
