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):Figure 4 and table 1
Annotation description:The paper examines the localization of kappa-type opioid receptor in dopaminergic terminals at the nucleus Accumbens using electron microscopic immunocytochemistry.
Fig. 4 shows a DAT-containing terminal in contact with kappa-type immunoreactive dendritic spines. The dendritic spine shows kappa-type opioid receptor labeling at the postsynaptic density and along extrasynaptic portions of the plasma membrane. The fraction of kappa-type opioid receptor immunoreactivities which opposes DAT labeling is quantified in table 1.
