The acute inflammatory response has been triggered in rat lungs by deposition of IgG immune complexes. The inflammatory reaction triggered is highly tissue damaging and requires activation of NF-κB with ensuing generation of chemokines and cytokines. Endogenous generation of IL-10 and IL-13 as well as secretory leukocyte protease inhibitor (SLPI), significantly regulates this inflammatory response. IL-10 and IL-13 attenuate NF-κB activation by interfering with breakdown of IκBα, while SLPI likewise suppresses NF-κB activation, but by interfering with breakdown of IκBβ. Antibody induced blockade of IL-10, IL-13 or SLPI enhances NF-κB activation in lung and exacerbates the lung inflammatory response and injury. These data indicate that endogenous IL-10, IL-13 and SLPI are important regulators of the inflammatory response by reducing gene activation with resultant generation of peptide mediators/cytokines and chemokines.
