Brain Pathway Amplifies Pain After Injury

Mouse Study Could Aid Development of Treatments for Chronic Pain

Tuesday, January 30, 2024

patient with shoulder injury talks with doctor

Getting hurt or sick is bad enough, but millions of patients around the world continue to experience pain or hypersensitivity even after their ailment resolves itself. Despite the prevalence of chronic pain, few effective treatments are available, especially ones without the potential for addiction that opioid medications carry. However, new IRP research has shown that suppressing the electrical firing of neurons in a certain brain area can alleviate injury-induced hypersensitivity in mice, providing a promising new target for treatments aimed at relieving chronic pain.

NIH Scientists Redesign Neurons to Enable Targeted Therapies

New Receptors and Radioactively Labeled Molecules Could Provide Useful Tools for Research and Medicine

Wednesday, March 17, 2021

neurons firing

Genetically modifying neurons to enable scientists and clinicians to influence brain activity probably sounds like the stuff of science fiction. However, the technology has existed for more than a decade, allowing scientists to make important leaps in understanding how neurons communicate with one another in healthy individuals and those with psychological and neurological conditions. What’s more, recent improvements to these tools developed by researchers led by IRP investigator Mike Michaelides, Ph.D., may allow neurologists to use them to deliver drugs to just the right brain cells to treat those ailments effectively without the side effects caused by current treatments.
