      Aim: 5-Lipoxygenase (5-LO)-leukotriene B4 (LTB4) signalling axis plays an important role in vascular inflammation, however, the cellular source of LTB4 in the injured vasculatures is unclear. To determine the hypothesis that vascular smooth muscle cells (VSMC) might be an active player in the secretion of LTB4 in the injured vasculatures, we examined LTB4 production and related signaling mechanisms in VSMC stimulated with HMGB1, a damage-associated molecular pattern.
