Annotated paper:Svingos AL, et al. "Major coexpression of kappa-opioid receptors and the dopamine transporter in nucleus accumbens axonal profiles" Synapse. 2001 Dec 1;42(3):185-92 PMID:11746715
Figure(s):Table 1, figures 1-3
Annotation description:The paper examines the localization of kappa-type opioid receptor in dopaminergic terminals at the nucleus Accumbens using electron microscopic immunocytochemistry.
Figure 1, 2 and 3 present immunoreactivities for kappa-type opioid receptors in axon terminals, partially localizing to DAT immunoreactivities (quantified in figure 1). The immunostaining is found at the axonal plasma membrane and at the membrane of small SVs.
