The gut–brain axis, a bidirectional neurohumoral communication system, is important for maintaining homeostasis and is regulated through the central and enteric nervous systems and the neural, endocrine, immune, and metabolic pathways, and especially including the hypothalamic–pituitary–adrenal axis (HPA axis). [2]
The gut–memory connection is the relation between the gastrointestinal tract and memory performance. The phenomenon of the gut–memory connection is based on and part of the idea of the gut-brain axis, a complex communication network, linking the central nervous system to the gut.
The brain-gut axis influences the entire body through a variety of pathways; it regulates sensory, motor, endocrine, autonomic, immune, and inflammatory reactions. Within the physical and psychological interactions of FGIDs specifically, psychiatric disorders such as anxiety, depression, and even autism are well-linked to GI dysfunction.
The gut microbiota contributes to digestion and immune modulation, as it plays a role in the gut-brain axis, where microbial metabolites such as short-chain fatty acids and neurotransmitters influence brain function and behavior. The gut–brain axis is the biochemical signaling that takes place between the gastrointestinal tract and the ...
[11] [3] Gut dysbiosis occurs when there is an alteration in the composition of the gut microbiota that leads to a dysfunction and an unhealthy state. [11] An overgrowth of bacteria in the small intestine can metabolize levodopa into dopamine, preventing it from reaching the brain. [17]
The key cellular components of the neuroimmune system are glial cells, including astrocytes, microglia, and oligodendrocytes. [1] [2] [5] Unlike other hematopoietic cells of the peripheral immune system, mast cells naturally occur in the brain where they mediate interactions between gut microbes, the immune system, and the central nervous system as part of the microbiota–gut–brain axis.
On the left side of the cell has microvilli extending into the gut lumen and the right side has a neuropod extending into the basal lamina propria. [ 1 ] A neuropod cell is a specialized enteroendocrine cell (i.e., sensory epithelial cell) within the gut that is capable of synapsing with afferent nerves.
Neural top–down control of physiology concerns the direct regulation by the brain of physiological functions (in addition to smooth muscle and glandular ones). Cellular functions include the immune system’s production of T-lymphocytes and antibodies, and nonimmune related homeostatic functions such as liver gluconeogenesis, sodium reabsorption, osmoregulation, and brown adipose tissue ...
