Project description:The human microbiota is believed to influence health. Microbiome dysbiosis may be linked to neurological conditions like Alzheimer’s disease (AD), amyotrophic lateral sclerosis (ALS) and Huntington’s disease (HD). We report the ability of a probiotic bacterial strain in halting neurodegeneration phenotypes. We show that Lacticaseibacillus rhamnosus HA-114 is neuroprotective in C. elegans models of ALS and HD. Our results show that neuroprotection from L. rhamnosus HA-114 is unique from other L. rhamnosus strains, and resides in its fatty acid content. Neuroprotection by L. rhamnosus HA-114 requires acdh-1/ACADSB, kat-1/ACAT1 and elo-6/ELOVL3/6, which are key fatty acid metabolism and mitochondrial b-oxidation genes. Our data suggest that disrupted lipid metabolism contributes to neurodegeneration and that dietary intervention with L. rhamnosus HA-114 restores lipid homeostasis and energy balance through mitochondrial b-oxidation. L. rhamnosus HA-114 is suitable for human consumption opening the possibility of modifying disease progression by dietary intervention.

Food-associated Lactiplantibacillus plantarum C9O4 reverts inflammation and apoptosis in intestinal epithelial cells: a proteomic insight

Project description:Nowadays, Western diets and lifestyle lead to an increasing occurrence of chronic gut inflammation, that represents an emerging health concern with still a lack of successful therapies. Fermented foods, and their associated Lactic Acid Bacteria, have recently regained popularity for their probiotic potential including the maintenance of gut homeostasis by modulating the immune and inflammatory response. Our study aims to investigate the cross-talk between the food-borne strain Lactiplantibacillus plantarum C9O4 and intestinal epithelial cells in an in vitro inflammation model. Cytokines profile shows the ability of C9O4 to significantly reduce levels of IL-2, IL-5, IL-6, and IFN-γ. Proteomic functional analysis reveals an active host-microbe interaction that highlights an immunoregulatory role of C9O4, able to revert both the detrimental effects of IFN-γ through the JAK/STAT pathway and the apoptosis process in inflamed cells. These results suggest a promising therapeutic role of fermented food-associated microbes for the management of gastrointestinal inflammatory diseases.
