1. We have studies showing repeated exposure alters the stress response system ." 2. They also play a role in maintaining a normal stress response cycle. 3. The stress response increases blood pressure, which can lead to a stroke. 4. The domain was originally discovered in the bacterial stress response to cadmium. 5. Decreased functioning of the MeCP2 protein thus upregulates the neuronal stress response . 6. It may be part of a metal sensing stress response system. 7. Alarming experiences, either real or imagined, can trigger a stress response . 8. Particularly, peptide sequences of some defense and stress response protein are significantly similar. 9. The ensuing physiological changes constitute a major part of the acute stress response . 10. Other observed differences include reduced stress response and increased exploration of novel environments.
