  • CANINE NARCOLEPSY IS ASSOCIATED WITH AN ELEVATED NUMBER OF ALPHA-2-RECEPTORS IN THE LOCUS COERULEUS BRAIN RESEARCH Fruhstorfer, B., Mignot, E., Bowersox, S., Nishino, S., Dement, W. C., Guilleminault, C. 1989; 500 (1-2): 209-214

    Abstract:

    alpha 2-Receptors in the canine brain were pharmacologically characterized using [3H]yohimbine binding. Competition studies revealed a single class of binding sites in frontal cortex but two distinct subtypes in nucleus caudatus. The role of central alpha 2-receptors in narcolepsy was investigated in 5 normal and 5 narcoleptic Doberman pinschers. Scatchard analysis of [3H]yohimbine binding in different brain areas revealed an increase in the number of alpha 2-binding sites limited to the locus coeruleus. This suggests that altered autoinhibition of norepinephrine release may be associated with the narcoleptic symptomatology.
