Pretreatment with HTS01037 attenuates PA-induced iNOS expression in BV2 microglia (p<0.001 PA vs. C, HTS, HTS+PA). In UCP2kd microglia, PA increases iNOS expression, however, HTS01037 is no longer able to attenuate PA-induced iNOS upregulation (p<0.05 C vs. HTS+PA, p<0.001 C vs. HTS, p<0.0001 C vs. PA, p<0.0001 PA vs. HTS, HTS+PA). Letters indicate significant differences between treatment groups.
