Dr. Alexander Niculescu and his team at the University of Arizona created a blood test to enhance diagnosis and treatment for chronic pain, which affects 20% of U.S. adults.
Their study identified 56 blood biomarkers associated with pain, including CD55 and ANXA1, and emphasized the link between chronic pain and mental health disorders.
Researchers from Stanford and NYU found that the gut microbe Bacteroides fragilis activates pain pathways related to inflammatory bowel disease (IBD) and developed nanoparticles to deliver a drug targeting pain receptors.
