Researchers have discovered that a particular molecular signaling pathway plays an important role in producing osteoarthritis (OA) pain. Using a mouse model of painful osteoarthritis, they show that ...

Scientists have re-created a pain pathway in the brain by growing four key clusters of human nerve cells in a dish. This laboratory model could be used to help explain certain pain syndromes, and ...

In a new discovery, chronic pain has been shown to be physiologically different from acute pain and now scientists have the roadmap for how to target it. Researchers from the University of Aberdeen, ...

Rheumatoid arthritis is a chronic autoimmune disease that affects millions of people worldwide. This disease prompts the immune system to mistakenly attack body tissues, particularly joints, leading ...

Scientists created a model of the human pain pathway in a dish by connecting four separate brain organoids. The feat should help them understand sensory disorders like those affecting pain perception.

Pain isn't just a physical sensation—it also carries emotional weight. That distress, anguish, and anxiety can turn a fleeting injury into long-term suffering. Subscribe to our newsletter for the ...

A newly identified brain pathway in mice could explain why placebos, or interventions designed to have no therapeutic effect, still relieve pain. Developing drugs that target this pathway may lead to ...

Researchers at UC Santa Barbara identified a pain pathway in fruit flies that reduces the sensation of pain from heat. The researchers discovered that just a single neuron on each side of the animal’s ...

Salk scientists uncover a key neural circuit in mice that gives pain its emotional punch, opening new doors for treating fibromyalgia, migraine, and PTSD LA JOLLA (July 9, 2025)—Pain isn’t just a ...
