Aim T0901317 is a synthetic liver X receptor (LXR) agonist. This study was to investigate the effects and potential mechanisms of T0901317 on proinflammatory cytokine release from lipopolysaccharide (LPS)-induced THP-1 macrophages. Methods Human THP-1 macrophages were induced using phorbol-12-myristate acetate (PMA, 160 nmol/L) for 24 h, then cells were divided into four groups: control group, LPS group, T0901317 group and LPS+T0901317 group. Secretion of proinflammatory cytokines, including tumor necrosis factor-α (TNF-α), interleu...
