Innate non-lymphoid cells While the integrity of junctions between epithelial cells and the differentiation of some of these cells into mucus-secreting goblet cells are vitally important for the cleulas of the intestinal mucosa, the fact that enterocytes play a much more complex role in the immune response than merely by regulating permeability is now increasingly clear 4.

Several ILC subpopulations have been identified in human tissues, both healthy and with various conditions, including secondary lymphoid organs, peripheral blood, lungs, and gut 26,52, Humoral immunity and intraepithelial lymphocytes.
