Abstract |
Lactobacillus plantarum is a well-documented probiotic that
has been used in clinical trials for the regulation of the immune
system and treatment of gastrointestinal diseases. In
this study, we evaluated the effects of L. plantarum cell lysates
on the immune regulation through the in vitro and in vivo
studies. L. plantarum lysates were prepared by sonication
method, and we observed that the repetition of disruption
step increased indicator components within the bacterial
lysates. Indicator components might affect TNF-α production.
L. plantarum lysates did not induce TNF-α production,
while LPS-induced TNF-α production was dramatically inhibited
in a sonication-dependent manner in THP-1 cells.
Oral administration of L. plantarum lysates effectively attenuated
the horny layer formation and decreased epidermal
thickening in NC/Nga mice skin. The damage to barrier function
after the 8 weeks oral administration was reduced by L.
plantarum lysates as compared to that in the atopic dermatitis
(AD) mice. Further study revealed that L. plantarum lysates
polarized Th1 response via induction of IL-12 and IFN-γ
production and inhibition of IL-4 and IgE production in
NC/Nga mice. Together, our results suggest that L. plantarum
lysates are remarkable material for host homeostasis and it
could be used for the treatment of inflammatory diseases. |
