Chronic stress? Limiting inflammatory signaling to specific brain circuits
Chronic stress is associated with the pathogenesis of psychological disorders such as depression. A study is the first to identify the role of a neuronal receptor that straddles the intersection between social stress, inflammation, and anxiety in rodent models of stress. Findings suggest the possibility of developing better medications to treat the consequences of chronic stress by limiting inflammatory signaling not just generally, which may not be beneficial in the long run, but to specific brain circuits.
