This study identifies Fgr kinase as a central player in governing autophagy within spinal microglia during the development of neuropathic pain. Using a rat model of chronic constriction injury (CCI), we found that damage to peripheral nerves causes a prolonged increase in Fgr expression specifically in microglia of the spinal dorsal horn (SDH). Genetic interventions and behavioral analyses demonstrated that Fgr overexpression induced pain symptoms, whereas Fgr knockdown alleviated pain hypersensitivity. Mechanistically, Fgr directly phosphorylated STAT3, promoting its nuclear translocation and suppressing autophagic flux, evidenced by reduced LC3-II/LC3-I ratio, accumulated SQSTM1, and diminished autophagosomes. Pharmacological inhibition of Fgr by intrathecal TL02-59 (10 μg/kg) restored autophagy, attenuated STAT3 activation, and reversed CCI-induced neuropathic pain behaviors.

In ischemic cerebrovascular disease, lactylation exerts dual roles: on one hand, it can induce neuronal death, exacerbate neuroinflammation, and form a vicious metabolic cycle; on the other hand, it can influence immune cell function and gene expression, thereby exerting neuroprotective effects. Accordingly, targeting lactate metabolism or lactylation-modifying enzymes holds considerable therapeutic potential.
