IL-6-deficient mice exhibit normal mucosal IgA responses to local immunizations and Helicobacter felis infection.

Abstract

Using IL-6-deficient (IL-6 -/-) or wild-type mice, we investigated whether IL-6 is involved in the intestinal adjuvant activity of cholera toxin (CT) and to what extent IL-6 is required for mucosal IgA responses against soluble protein Ags or live Helicobacter felis infection. In naive IL-6 -/- mice we found normal total IgA levels in serum, bronchial and… (More)
