Project description:The study evaluates the effect of Lactiplantibacillus plantarum IMC 510® supplementation on anthropometric and biochemical parameters, GM composition and gastrointestinal and general symptoms of overweight/obese subjects.
Project description:We report the whole-genome sequence of Lactobacillus plantarum SPC-SNU 72-2, a probiotic starter for sourdough. Genome sequencing was completed using the Pacific Biosciences RS II and Illumina platforms. This study will facilitate the understanding of microbial characteristics of L. plantarum SPC-SNU 72-2 and its roles during sourdough fermentation.
Project description:This study was conducted to analyze phenotypic and proteomic differences of two Lactiplantibacillus plantarum strains (WCFS1, model strain from human saliva, and CIP104448, stool isolate) when a biofilm was produced under static conditions (well researched), or with the addition of flow (novel).
Project description:Probiotics have been suggested to ameliorate the function of the intestinal epithelial barrier and so have several mediators and receptors of the expanded endocannabinoid system, the endocannabinoidome (eCBome). Here we cocultured three live strains of Lactiplantibacillus plantarum with intestinal epithelial organoids to study their effects on the gut barrier function and the possible involvement of the eCBome in this effect. All three L.plantarum strains variously reduced the trans-epithelial permeability of intestinal organoids and promoted increased mRNA expression of several tight junction proteins and intestinal barrier proteins. Concomitantly, the three strains upregulated the expression of genes encoding biosynthetic enzymes (i.e., NapePLD, Abdh4, Gde1, Daglb) and receptors (i.e., Cnr1, Cnr2, Gpr55, and Ppara), while concurrently downregulating the expression of two essential catabolic enzymes (i.e. Faah and Naaa), involved in the signaling of several eCBome mediators known for their role in regulating the intestinal epithelial barrier. Selective inhibitors of eCBome mediator degrading enzymes FAAH and MAGL, i.e., URB597 and JZL184, increased N-acyl-ethanolamine (NAE) and 2-monoacylglycerol (2-MAG) levels, respectively, enhanced the expression of intestinal epithelial barrier genes and reduced the trans-epithelial permeability of organoids, as for L. plantarum strains. Interestingly, inflammation-induced trans-epithelial permeability in organoids was also reversed by both FAAH and MAGL inhibitors. We surmise that elevated endogenous levels of either NAEs or 2-MAGs promote improvement in small intestine trans-epithelial permeability and that L. plantarum strains may exploit this mechanism to promote these beneficial effects.
