 AB    Previous studies have shown that morphine stimulates simian
       immunodeficiency virus (SIV) replication in SIV-infected human CEM x174
       cells as well as in monkey lymphocytes through a mechanism of delaying
       the lysis of infected cells (Biochem. Biophys. Res. Commun.
       195:1165-1173, 1993). The present study describes the identification of
       brain-like opioid receptor sequences in RNA transcripts of both CEM x174
       cells and monkey lymphocytes. Study of the gene sequence of a lymphocyte
       opioid receptor encompassing the third transmembrane domain and the
       third cytoplasmic loop indicates a 96% homology in amino acid
       composition to the delta opioid receptor in brain cells. Expression of
       such an opioid receptor sequence in lymphocytic cells is constitutive,
       since it could be detected in both saline-treated and morphine-treated
       monkeys as well as in morphine-treated monkeys after detoxification.
