To assess the impact of vagotomy on the IgA-response, male BALB/c mice underwent anterior vagotomy or a sham procedure were sacrificed on day 14 post-operation and the proximal and distal small-gut segments were dissected. In intestinal lavages IgA/IgM antibodies were analysed by ELISA; in Peyer's-patches and lamina-propria cell suspensions the intracellular IgA-associated interleukins (ILs) and pro-inflammatory cytokines in CD4+ T cells were analysed by cytofluorometry. Vagotomy reduced the IgA or increased the IgM antibody concentration in both segments and reduced or increased the lamina- propria CD4+ T cell pro-inflammatory cytokine responses in the distal or proximal segments, respectively. Data show the role of the vagus nerve on the IgA response.
