The inhibition of 5-Lipoxygenase (5-LO) products leukotriene B4 (LTB 4 ) and cysteinyl leukotrienes (cysLTs) modulates the inflammatory response and improves cutaneous wound healing

To analyze the participation of the enzyme 5-lipoxygenase (5-LO) in skin repair, WT wounds were compared to those in 5-LO deficient mice (5-LO-/-), which presented faster closure and reduced inflammatory infiltrate in the skin, together with increased CD4 regulatory T cells markers in the draining lymph nodes. The 5-LO-/- wounds also had diminished TNF-α, CCL11, CCL7, CCL2, CXCL9, CCR1 and CXCR2 mRNA expression in the lesions, besides...
