Anti-inflammatory and anti-osteoporotic potential of Lactobacillus plantarum A41 and L. fermentum SRK414 as probiotics

Lee, Chul Sang, Kim, Sae Hun·2020·Probiotics and Antimicrobial Proteins

Abstract

This study involves an investigation on the probiotic properties of lactic acid bacteria and their potential applications in an in vitro model of lipopolysaccharide (LPS)-stimulated inflammation and dexamethasone-induced osteoporosis. Nine strains were pre-screened from 485 lactic acid bacteria based on their survival at a low pH and in a solution containing bile salts. All candidates were capable of surviving in an environment with low pH and with bile salts and could successfully colonize the intestine. Furthermore, their functional properties, such as anti-oxidation and anti-inflammation, were evaluated. Of the nine probiotic candidates, Lactobacillus plantarum A41 and L. fermentum SRK414 exhibited the highest anti-oxidative capacity. Moreover, only L. plantarum A41 and L. fermentum SRK414 could increase gut barrier function by upregulating the mRNA expression of tight junction proteins and inhibit the expression of inflammatory mediators induced by LPS-stimulated inflammation. Interestingly, these two strains were also capable of regulating several bone metabolism-related markers playing a role in bone homeostasis and osteoblast differentiation. In brief, L. plantarum A41 and L. fermentum SRK414 exhibited high probiotic potential and potentially impact immune-related bone health by modulating pro-inflammatory cytokines and bone metabolism-related markers.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
