Neurotrophic factors in enteric physiology and pathophysiology

Area of Science:

• Neuroscience
• Gastroenterology
• Cell Biology

Background:

• Neurotrophic factors are vital for nervous system development and neuronal survival.
• In the adult gut, they regulate sensation, motility, and barrier function.
• Emerging roles in gut pathophysiology are increasingly recognized.

Purpose of the Study:

• To review recent advances in understanding neurotrophic factor functions in the adult gut.
• To highlight the role of brain-derived neurotrophic factor in bowel obstruction-induced pain.

Main Methods:

• Literature review of neurotrophic factor roles in the gastrointestinal tract.
• Analysis of studies investigating neurotrophic factors in gut physiology and pathology.

Main Results:

• Neurotrophic factors are essential for enteric nervous system development and function.
• In adults, they modulate gut sensation, motility, and epithelial integrity.
• Brain-derived neurotrophic factor is implicated in distention-induced abdominal pain in bowel obstruction.

Conclusions:

• Neurotrophic factors have critical physiological and pathophysiological roles in the adult gut.
• Further research into their involvement in gastrointestinal disorders is warranted.
