Lipoxin and resolvin biosynthesis is dependent on 5‐lipoxygenase activating protein

Abstract: Resolution of acute inflammation is an active process coordinated by proresolving lipid mediators (SPMs) such as lipoxins (LXs) and resolvins (Rvs), which are formed by the concerted action of 2 lipoxygenases (LOs). Because the exact molecular mechanisms of SPM biosynthesis are not completely understood, we aimed to investigate LX and D-type Rv formation in human leukocytes and HEK293T cells overexpressing leukotriene (LT) pathway enzymes. Activity assays in precursor (15-hydroxyeicosatetraenoic acids, 17-HDoH… Show more

“…The literature on 5-LO in M1 and M2 Mfs is controversial. Higher 5-LO and FLAP protein expression has been reported for M1 (23), whereas other reports showed that ALOX5 mRNA was higher in M2 compared with M1 (5, 24). CLP, the other 5-LO accessory protein that also binds to F-actin, was slightly higher in M-CSF Mfs, whereas LTA 4 hydrolase was equally expressed in both cell types.…”

“…LTC4, LTD4 and LTE4 are known collectively as the cysteinyl leukotrienes and are reported to have a role in inflammatory cell recruitment, smooth muscle contraction, vessel dilation and permeability [53] (Figure 2). 5-LO is also involved in the synthesis of another type of AA-derived metabolite called Lipoxins, such as LXA4 and LXB4 which have anti-inflammatory and pro-resolving properties [54,55]. …”
