  • Title: Postnatal changes in the activity ratio of specific and nonspecific cholinesterases from neuronal perikarya.
    Author: Ochoa EL, Brusco A, Idoyaga-Vargas VP, Carminatti H.
    Journal: J Neurochem; 1982 May; 38(5):1236-40. PubMed ID: 7062049.
    Abstract:
    A soluble fraction from rat brain neuronal perikarya was shown to contain both the specific and nonspecific forms of the enzyme acetylcholinesterase (EC's 3.1.1.7. and 3.1.1.8., respectively). The ratio of the enzyme activities varied along the course of brain development: the nonspecific form being predominant from 1 to 15 days of age and the specific one showing the pattern of rising activity from day 15 onward. We suggest a possible relationship between this changing in cholinesterase activities and the establishment of synapses within the rat cerebral cortex.
