Goblet cells deliver small intestinal luminal material to the lamina propria dendritic cells of the tolerogenic CD103 . Then, why are there more goblet cells in the large intestine? It helps in the absorption of \(B12\) in the ileum. SMs that line the stomach lumen and the GPs have a columnar shape and secrete an alkaline, highly viscous mucous substance rich in bicarbonate ions that helps to protect the stomach mucosa from abrasive food particles and erosive gastric acid. The enteroendocrine cells secrete hormones, which regulate intestinal functioning, controlling peristalsis, appetite, secretory function of other glands, and other physiological processes. Goblet cells are distributed individually in the mucous membranes of the intestine, air passages, efferent ducts of the pancreas and parotid glands .

Single cell RNAseq data has revealed that goblet cells have high expression of Myosin 5b (Myo5b), a molecular motor that regulates vesicle trafficking in epithelial cells. Goblet cells produce small amounts of mucus continually, which is known as basal (constitutive) secretion. 1 answer. The perspective regarding goblet cells and mucus has changed, with current evidence suggesting that they are not passive but play a positive role in maintaining intestinal tract immunity and mucosal homeostasis. GCs can also participate in the immune response through nonspecific endocytosis and goblet cell-associated antigen passages (GAPs).
