Final answer:
Paneth cells are specialized gut epithelial cells that secrete antimicrobial peptides, differing from Goblet cells which secrete mucus.
Step-by-step explanation:
Gut epithelial cells specialized in the secretion of antimicrobial peptides are called Paneth cells. These cells are found in the small intestine, particularly at the base of the intestinal crypts. While Goblet cells are responsible for mucus secretion that lubricates the digestive tract and traps incoming microorganisms, Paneth cells specifically secrete antimicrobial peptides that can help control the bacterial population in the gut, contributing to the immune defense of the gastrointestinal tract. The gut epithelial cells specialized in the secretion of antimicrobial peptides are called Paneth cells. These cells are found in the small intestine, particularly in the crypts of Lieberkuhn.
