The placebo effect has long been dismissed as purely psychological, regarded as a mental trick with no real biological basis.

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 ...

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.

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 ...

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 ...

Researchers integrated four organoids that represent the four components of the human sensory pathway, along which pain signals are conveyed to the brain. Stimulation of the sensory organoid (top) by ...
