Study Notes
Microbiota-Gut & Brain Axis
- Microbial communities, using metagenomic analysis, have a significant influence on the gut and the brain
- Differences in gut microbe composition are associated with many diseases, including inflammatory diseases and autoimmune conditions
- Studies show various species of bacteria in the gut and a correlation to the diversity and health in different locations
- The gut microbiome can affect brain function via the immune system, which interacts directly or indirectly with the central nervous system (CNS)
- Gut microbiota also communicates with the CNS, potentially through neural endocrine and immune pathways, influencing brain function and behavior
- A link exists between gut microbiota alterations, stress, and mood changes
- Dysbiosis (an imbalance of gut microbiota) is associated with several diseases
- Gut microbiota plays a role in the development of the central nervous system (CNS)
Gut Microbiota and Human Health
- Different bacterial and yeast species populate various anatomical locations in humans
- The most abundant bacterial phyla in the human gut microbiome are Firmicutes and Bacteroidetes
- Several factors influence the composition and diversity of the gut microbiome, such as diet, age, and environment
- Differences in gut microbiome composition have been observed in individuals with various diseases such as Alzheimer’s disease, Inflammatory bowel disease, colorectal cancer, and many others
Gut Microbiota and Neurological Function
- The gut microbiome influences neurological functions, including mood, cognition, and behavior
- Gut microbiota communicates with the CNS possibly via neural and endocrine pathways and affects neuronal functions
- Immune response plays an important role in the interaction between gut microbiota and neurological functions.
- Dysbiosis is implicated in the pathophysiology of several neurological diseases such as Parkinson's, Alzheimer's, MS, autism, and depression
- Probiotics have shown potential for modulating gut microbiome composition and improving some neurological conditions
Gut-Brain Axis and Disease
- Microbial composition alterations can lead to immunological changes that affect the CNS and affect the body's response to stress, resulting in neurological conditions
- Microbiota dysbiosis is associated with a variety of neurological diseases, including Alzheimer's and Parkinson's diseases, and other neurological conditions
- A dysbiotic gut microbiome can induce increased gut permeability, impacting systemic inflammation and affecting the CNS
- Microbial metabolites may influence different neurological functions
- There are several bidirectional interactions between the gut microbiota, the gut-brain axis, and the CNS
Gut-Brain Axis Mechanisms
- Alterations in the composition and function of gut microbiota can affect the production and turnover of neurotransmitters, impacting mood, behavior, and cognition
- Microbiota can alter mucosal immune response and inflammation, which in turn can affect the CNS
- Microbiota metabolites, such as SCFAs, affect the gut-brain axis influencing various neurological functions
- The gut microbiota can influence neurological function, particularly through the vagus nerve
