Urease-based mucosal immunization against Helicobacter heilmannii infection induces corpus atrophy in mice

Infect Immun. 1999 Nov;67(11):6206-9. doi: 10.1128/IAI.67.11.6206-6209.1999.

Abstract

Mucosal immunization with Helicobacter heilmannii urease B or Helicobacter pylori urease, given nasally with cholera toxin, protects BALB/c mice against H. heilmannii infection and significantly reduces a preexisting infection. However, immunization aggravates gastric corpus atrophy. Our results underline the necessity of defining immunization regimens that do not enhance mucosal damage.
