After six years of work, an International Association for the Study of Pain (IASP) Working Group led by Rolf-Detlef Treede, Heidelberg University, Mannheim, Germany, and co-chair Winfried Rief, Philipps-Universität…

Past experiences shape our expectations about the future, and those expectations can simultaneously affect how we experience new events. Sometimes this can result in a self-fulfilling prophecy where people…

Botulinum toxin, a neurotoxin made by the bacterium Clostridium botulinum, inhibits neuronal signaling by blocking neurotransmitter release, leading to paralysis. Researchers from University College London (UCL), UK; the University…

Non-peptide opioid drugs like morphine and fentanyl bind to opioid receptors (ORs) on the neuronal cell membrane, just as naturally occurring peptide OR ligands do, to bring about analgesia.…

Patients who take opioids for chronic pain typically develop tolerance to these drugs. Now, researchers led by Taka-aki Koshimizu, Jichi Medical University, Shimotsuke, Japan, and Yukio Takano, Fukuoka University,…

Pain researchers and advocates are cheering the announcement of the HEAL (Helping to End Addiction Long-term) Initiative, which promises to roughly double US National Institutes of Health (NIH) funding…

Survival is the prime directive of every animal, and it takes work. Animals are under constant threat from starvation, thirst, extreme temperatures, and life-threatening injury and illness. But when…

For decades, researchers have looked for the molecular sensors tuned to potentially harmful heat. Now, a team led by Joris Vriens and Thomas Voets, University of Leuven, Belgium, has…

Opioids provide rapid and potent pain relief, but these drugs are associated with numerous side effects, including respiratory depression, tolerance, dependence, and addiction. Now, a new study led by…

Animals, including humans, can sense mechanical force in a myriad of forms―as light touch, vibration, and even muscle tension, among others. Yet all of these seem to be detected…

The following is a report on two nanosymposiums on pain held at the 2017 Society for Neuroscience annual meeting, which took place November 11-15 in Washington, DC. See other…

Editor's note: This is Part 1 of PRF’s coverage of selected talks from a pre-conference workshop on pain and aging held at the 2017 International Association of Gerontology and…

Developing safer opioids remains a long-held goal of pain researchers, who have especially set their sights on the mu opioid receptor (MOR). Agonists that bind MORs can activate multiple…
