Luteolin attenuates RA-associated chronic pain by targeting the LDHA/H3K9la/NFATC2 axis to suppress Th17 cell differentiation and central infiltration

T dynamics. Biophysical validation through molecular docking, surface plasmon resonance (SPR), and molecular dynamics (MD) simulations established LUT's direct binding to LDHA with high affinity. Collectively, these findings delineate a novel therapeutic paradigm wherein LUT alleviates RA-associated chronic pain by orchestrating Th17 differentiation and migratory capacity through coordinated blockade of the LDHA-H3K9la-NFATC2 signaling network, highlighting its potential as a disease-modifying agent for chronic pain management in RA.
