The vagus nerve as a modulator of intestinal inflammation.
The cholinergic nervous system attenuates the production of pro-inflammatory cytokines and inhibits inflammatory processes. Hence, in animal models of intestinal inflammation, such as postoperative ileus and dextran sulfate sodium-induced colitis, vagus nerve stimulation ameliorates disease activity. On the other hand, in infectious models of microbial peritonitis, vagus nerve activation seemin...
متن کاملVagus Nerve as Modulator of the Brain–Gut Axis in Psychiatric and Inflammatory Disorders
The vagus nerve represents the main component of the parasympathetic nervous system, which oversees a vast array of crucial bodily functions, including control of mood, immune response, digestion, and heart rate. It establishes one of the connections between the brain and the gastrointestinal tract and sends information about the state of the inner organs to the brain via afferent fibers. In th...
متن کاملModulation of the Innate Immune Response through the Vagus Nerve.
The innate immune system is a defense mechanism that is of vital importance to our survival. However, excessive or unwanted activation of the innate immune system, which can occur in major surgery, sepsis, trauma, ischemia-reperfusion injury and autoimmune diseases, can lead to damage of the kidneys and other organs. Therefore, therapeutic approaches aimed at attenuating the innate immune respo...
متن کاملIntestinal microbiota impact sepsis associated encephalopathy via the vagus nerve
OBJECTIVE The pathogenesis of sepsis associated encephalopathy (SAE) remains poorly understood. Vagus nerve plays an important role in gut-microbiota-brain axis. This study aimed to investigate whether vague nerve is a key mediator of the impact of intestinal microbiota on SAE. METHODS Male rats were randomly divided into four groups (n=20): SHAM (SH) group, lipopolysaccharide (LPS) group, fe...
متن کاملInnate Immune Activation in Intestinal Homeostasis
Loss of intestinal immune regulation leading to aberrant immune responses to the commensal microbiota are believed to precipitate the chronic inflammation observed in the gastrointestinal tract of patients with inflammatory bowel diseases (IBD), Crohn’s disease and ulcerative colitis. Innate immune receptors that recognize conserved components derived from the microbiota are widely expressed by...
