Gastrointestinal Tract Wall Stretch Receptor (N/A)

Gastrointestinal tract wall stretch receptors are mechanosensitive neurons located within the muscular layers of the gut. They detect physical distension during digestion, primarily through IGLEs expressing GLP1R and potentially IMAs. Activation leads to vagal afferent signaling to the brainstem, regulating satiety, gastrointestinal motility, and digestive reflexes. Understanding these receptors may offer insights into appetite regulation and gastrointestinal disorders.

Activation by mechanical stretch of the gut wall, leading to increased firing of vagal afferent neurons and downstream signaling in the brainstem to modulate appetite and gastrointestinal motility.
