title: Proteomics analysis by two-dimensional differential gel electrophoresis reveals the lack of a broad response of Neisseria meningitidis to in vitro-produced AI-2.
abstract: To investigate the effect of the autoinducer AI-2 on protein expression in Neisseria meningitidis, a luxS mutant of strain MC58 was grown in the presence and absence of in vitro-produced AI-2, and differential protein expression was assessed by two-dimensional differential gel electrophoresis. N. meningitidis did not show a global response to AI-2 signaling activity.
