As of 2026-09-13

Delta-type opioid receptor shows approved-linked disease relevance led by alcohol dependence. 5 more disease programs remain visible in the same review block. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt P41143. Start with alcohol dependence, then reuse UniProt P41143 as the stable protein anchor across project notes and exports.

Disease program
alcohol dependence

Delta-type opioid receptor shows approved-linked disease relevance led by alcohol dependence. 5 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

Start review with alcohol dependence because it currently carries approved-linked support. Linked drugs include NALMEFENE HYDROCHLORIDE DIHYDRATE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
