QUICK LINKS

Leukotriene B4-d4 is a lipid mediator that plays a role in the inflammatory response. It is involved in the activation and chemotaxis of leukocytes, particularly neutrophils, at the site of inflammation. This chemical functions by binding to specific receptors on the surface of leukocytes, triggering a signaling cascade that leads to the release of pro-inflammatory cytokines and the amplification of the immune response. Leukotriene B4-d4 also promotes the adhesion of leukocytes to the endothelium, facilitating their migration into the inflamed tissue. At the molecular level, this chemical modulates the activity of various enzymes and transcription factors involved in the regulation of inflammatory pathways. Its mechanism of action involves the activation of intracellular signaling pathways, leading to the production of reactive oxygen species and the release of inflammatory mediators.
