Abstract
Secretory component (SC) is the receptor that facilitates transcytosis of polymeric IgA and polymeric IgM through secretory epithelial cells and into exocrine fluids. The present study showed that rTNF-alpha enhanced the cellular pool, membrane expression, and secretion of functionally SC in a human colonic carcinoma cell line (HT-29m2) which is known to express and process SC like normal glandular cells. TNF-alpha also up-regulated membrane expression of the constitutive HLA class I molecules, whereas the cells remained HLA class II-negative.Entities:
