Opioids are powerful analgesics but carry many contingencies that can lead to opioid-use disorder. Significant energy has been invested in understanding the molecular actions of the opioid alkaloids, particularly their relationship with the opioid receptors at the cell surface. However, there is gro...

Effects of HIV infection and opioids on gut microbiota
Opioid use is associated with worse outcome in HIV-infected patients. The exacerbated disease progression by opioids is mainly driven by increased epithelial damage and less regenerative response. The present study investigates how opioids potentiate HIV disease progression by impairing intestinal e...

Effect of short-term prescription opioids on DNA methylation of the OPRM1 promoter
Opioid analgesics are frequently prescribed in the United States and worldwide. However, serious side effects such as addiction, immunosuppression and gastrointestinal symptoms limit long term use. In the current study using a chronic morphine-murine model a longitudinal approach was undertaken to i...

Opioids such as morphine have many beneficial properties as analgesics, however, opioids may induce multiple adverse gastrointestinal symptoms. We have recently demonstrated that morphine treatment results in significant disruption in gut barrier function leading to increased translocation of gut co...
