[c-fos Gene expression during emotional stress in rats: blocking by delta sleep-inducing peptide].
An emotional stress induces an obvious immediate early gene c-fos expression in the brain limbic structures in the rats predisposed to emotional stress. Administration of the delta-sleep-inducing peptide (DSIP) was shown to inhibit the c-fos expression. It led to an obvious inhibition of the c-fos expression in paraventricular nuclei of the hypothalamus, medial and lateral parts of the septum of rats predisposed to emotional stress. This mechanism seems to play an important role in the DSIP anti-stress effects.
