Upregulation of AK7 in ACC-VTA glutamatergic projections contributes to chronic inflammation pain in male mice.

Upregulation of AK7 in ACC glutamatergic neurons drives chronic inflammation pain via the ACC-VTA circuit in male mice.

• Why it matters: Understanding the neural and molecular mechanisms underlying chronic pain is crucial for developing targeted treatments, as current knowledge of specific circuits and targets remains limited.
• What they did: Researchers used male mice to investigate the role of AK7 in the ACC, employing methods to manipulate its expression and measure neuronal activity and pain behaviors, focusing on the ACC and VTA regions.
• The result: Elevating AK7 levels increased neuronal activity and pain, while reducing AK7 alleviated pain, highlighting AK7 as a potential molecular target for managing chronic inflammation pain.
