摘 要:Sensitization of central pain and inflammatory pathways play essential roles in migraine,a primary neurobiological headache disorder.Since hypoxia-inducible factor-1α(HIF-1α)is implicated in neuroprotection and inflammation inhibition,herein we investigated the role of HIF-1αin migraine.A chronic migraine model was established in mice by repeated injection of nitroglycerin(10 mg/kg,i.p.)every other day for 5 total injections.In the prevention and acute experiments,roxadustat,a HIF-1αstabilizer,was orally administered starting before or after nitroglycerin injection,respectively.Pressure application measurement,and tail flick and light-aversive behaviour tests were performed to determine the pressure pain threshold,thermal nociceptive sensitivity and migraine-related light sensitivity.At the end of experiments,mouse serum samples and brain tissues were collected for analyses.We showed that roxadustat administration significantly attenuated nitroglycerin-induced basal hypersensitivity and acute hyperalgesia by improving central sensitization.Roxadustat administration also decreased inflammatory cytokine levels in serum and trigeminal nucleus caudalis(TNC)through NF-κB pathway.Consistent with the in vivo results showing that roxadustat inhibited microglia activation,roxadustat(2,10,and 20μM)dose-dependently reduced ROS generation and inflammation in LPS-stimulated BV-2 cells,a mouse microglia cell line,by inhibiting HIF-1α/NF-κB pathway.Taken together,this study demonstrates that roxadustat administration ameliorates migraine-like behaviours and inhibits central pain sensitization in nitroglycerin-injected mice,which is mainly mediated by HIF-1α/NF-κB/inflammation pathway,suggesting the potential of HIF-1αactivators as therapeutics for migraine.
