Implication

Experimental findings demonstrate that GPR35 activation alleviates pain and emotional disturbances, indicating its therapeutic potential.

Key Points

This research investigates the role of GPR35 in neuropathic pain and associated depression in the anterior cingulate cortex.
Measured GPR35 expression in blood samples from neuropathic pain patients and healthy controls.
Utilized chronic constriction injury (CCI) in mice to model neuropathic pain.
Performed lentiviral knockdown and overexpression of GPR35 in ACC cells.
Conducted behavioral assays to assess pain sensitivity, cognitive abilities, and depressive behaviors.
Carried out molecular analyses including western blotting and RNA sequencing.
Higher GPR35 levels correlated positively with pain intensity in neuropathic pain patients.
CCI in mice led to increased GPR35 expression and behavioral impairments.
GPR35 knockdown worsened pain sensitivity and depressive behaviors, while overexpression improved both.
Identification of Nr4a1 as a key regulator by GPR35, crucial for its protective effects.
L-Kyna treatment reduced pain hypersensitivity and improved mood in CCI mice.
