Anti-microbial peptide gene expression during oral vaccination: analysis of a randomized controlled trial.

ABSTRACT: We have observed previously that micronutrient supplementation ameliorated suppression of α-defensin expression during diarrhoea. However, how interactions between anti-microbial peptide (AMP) expression and diarrhoeal disease are altered by micronutrient supplementation remain unclear. Using oral vaccination as a model of intestinal infection, we measured changes in AMP expression during multiple micronutrient supplementation. In the first part, volunteers underwent duodenal jejunal biopsy before and at 1, 2, 4 or 7 days after administration of one of three live, attenuated oral vaccines against rotavirus, typhoid and enterotoxigenic Escherichia coli. In the second part, participants were randomized to receive a multiple micronutrient supplement or placebo for 6 weeks before undergoing in
