Antiretroviral Therapy Combined With CRISPR Gene Editing Can Eliminate HIV Infection in Mice

February 2020
This study found that HIV-1 could be eliminated in mice using a combination of two antiviral technologies—long-acting viral reservoir–targeted antiretroviral therapy and CRISPR/Cas-9 gene editing. HIV was undetectable in 9 out of 23 mice that received the combination treatment. HIV was not eliminated in any of the mice that were given either treatment alone.

Novel Dopamine D3 Receptor Antagonist Reduces Opioid Addiction-Like Behaviors in Rats

January 2020
The dopamine D3 receptor antagonist VK4-116 reduced oxycodone self-administration in rats, as well as drug-seeking behaviors after oxycodone reinstatement following withdrawal. VK4-116 did not interfere with oxycodone’s pain-relieving effects

α2δ-1–NMDA Receptor Interactions Are Responsible for Increases in Pain Sensitivity Caused by Opioids

December 2019
In animal studies, α2δ-1 and its interactions with NMDA receptors in the spinal cord triggered the pain sensitivity and analgesic tolerance that occurs with chronic morphine treatment. Blocking the α2δ-1–NMDA interaction reduced opioid-induced hyperalgesia and analgesic tolerance.
