  • Title: Decreased levels of preprotachykinin-A and tachykinin NK1 receptor mRNA in specific region of the rat striatum after electroconvulsive stimuli.
    Author: Zachrisson O, Mathé AA, Lindefors N.
    Journal: Eur J Pharmacol; 1997 Jan 29; 319(2-3):191-5. PubMed ID: 9042590.
    Abstract:
    The effects of electroconvulsive stimuli on the expression of mRNAs coding for preprotachykinin-A and the substance P-sensitive tachykinin NK1 receptor were examined in subregions of the rat striatum. In the electroconvulsive stimuli-treated animals, a 43% decrease in preprotachykinin-A mRNA was detected in the dorso-lateral caudate-putamen as compared to sham electroconvulsive stimuli treated animals. A 75% decrease in numerical density of tachykinin NK1 receptor mRNA positive neurons was found in the caudal part of the nucleus accumbens core. These findings provide new evidence for selective effects of electroconvulsive stimuli on specific populations of neurons in the rat striatum.
