Interleukin-1 induces mucus secretion from mouse intestinal explants.

Abstract

Secretion of goblet cell (GC) mucus occurs during immune reactions in the gut. As human macrophages produce a substance that induces mucus secretion from lung explants, we tested the effect of macrophage-derived factor(s) on mucus secretion from intestinal explants. Fragments of mouse duodenum were incubated with macrophage culture supernatants and purified interleukin-1 (IL-1) preparations, and the amount of mucus released was estimated by an enzyme-linked lectin assay. Both the culture supernatants and the IL-1 preparations induced dose- and time-dependent mucus release. Lipopolysaccharide-induced culture fluids were shown to contain IL-1. Thus, stimulation of mucus secretion from GC can be added to the list of biological activities attributable to IL-1.
