Figure 3. SDS page analysis of secreted Bacillus cereus proteins after 1 or 13(SP) or Substance P reverse (SPrev) (10⁻⁶ M).

Bacteria exposed for 1 h to SP showed an increase in the production of the collagenase (ColT) and of superoxide dismutase (SOD). Bacteria treated for 13 h with SP presented in contrast an increase in the S-layer crystal protein (SL). Results are representative of three independent experiments.
