In two separate studies, researchers have identified how peripheral nerve injury can lead to increased pain sensitivity. The studies were published on May 25, 2022, in Nature and May 26, 2022, in Science, respectively. The mechanisms they identify could lead to new therapeutic approaches to chronic pain and/or pain hypersensitivity.

A new study is shedding further light on the link between aging and neurodegenerative disease, after researchers found that protein turnover occurs about 20% slower in the brains of older mice compared with younger mice, affecting distinct pathways linked to these diseases.
