HIV protein: Tat
Interaction type: upregulates
Description: Morphine treatment in the presence of Tat significantly increases intracellular expression of opioid receptors (mu, delta, and kappa) and prevents morphine-induced cell surface opioid receptor down-regulation in microglia

HIV protein: Tat
Interaction type: interacts with
Description: The synergistic upregulation of CXCL10 expression by HIV-1 Tat and IFN-gamma is inhibited by mu-opioid receptor (MOR) antagonist beta-funaltrexamine in human astrocytes

HIV protein: Envelope surface glycoprotein gp120
Interaction type: upregulates
Description: HIV-1 gp120 upregulates mu opiate receptor expression in human vascular endothelium; in contrast, morphine decreases mu opioid receptor expression

HIV protein: Envelope surface glycoprotein gp120
Interaction type: upregulates
Description: HIV-1 gp120 upregulates mu opioid receptor (MOR) expression in TPA-differentiated HL-60 cells; treatment with TNF-alpha neutralizing antibody as well as anti-TNF-alpha receptor type II (TNFR-II) antibody, inhibits gp120-induced upregulation of MOR
