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.

Effect of Lacticaseibacillus rhamnosus 0030 on nucleus accumbens gene expression in high-fat diet fed mice

Project description:To investigate the effect of Lacticaseibacillus rhamnosus 0030 (LR) on nucleus accumbens gene expression in a mouse model of established diet-induced obesity, we treated high-fat diet fed male mice with 1x10^8 CFU LR using daily peroral gavage. Vehicle (here: PBS)-treated mice fed with a low-fat diet or high-fat diet served as controls. We then performed gene expression profiling analysis using data obtained from RNA-seq of those three groups (LFD vehicle, HFD vehicle, HFD LR).
