Study reveals a new gut-brain connection in amyotrophic lateral sclerosis (ALS). The gut microbiome could influence the severity of the neurodegenerative disease. Altering the bacteria in the gut may prevent or improve symptoms of ALS.
Researchers have honed in on a link between genetics, the gut microbiome, and memory. A new study identified a lactate as a key memory-boosting molecular messenger in mouse models. Mice fed Lactobacillus microbes had increased levels of GABA in their brains.
Enteric neurons appear to play a key role in the development of Parkinson's disease. The findings support the hypothesis and previous studies that the neurodegenerative disease may start in the gut before spreading to the brain. Researchers also found oligodendrocytes were affected during the early stages of Parkinson's, even before the loss of dopaminergic neurons.
Sweet tasting foods don't only trigger the taste buds, they also switch on a neurological pathway that begins in the gut. In the intestines, signals of sugar ingestion travel to the brain, sparking an appetite for more sweet foods. However, this pathway only responds to sugars, not artificial sweeteners.
Study reveals a novel learning process orchestrated between the digestive system and brain that compels animals to seek out novel foods.
Microbiota-derived short-chain fatty acids (SCFA) modulate stroke recovery. The effect was mediated by circulating lymphocytes on microglia activation. The study reports SCFAs could be a potential therapeutic to improve post-stroke recovery.
Short-chain fatty acid supplementation improves stroke recovery in mouse models.
Increased levels of Smad7 in T-cells is linked to multiple sclerosis-like symptoms in mice. In the intestines, the T-cells were more frequently activated and migrated to the central nervous system, where they triggered inflammation. Similar activation was seen in human patients with multiple sclerosis. The findings provide further evidence that multiple sclerosis may start in the intestines and spread via the CNS.
