Leukotriene B3 (LTB3) is primarily involved in inflammatory and immune responses within the body. It acts as a signaling molecule, attracting immune cells such as neutrophils to sites of inflammation or infection, thereby playing a key role in the body's defense mechanisms. LTB3 is also studied for its potential role in various inflammatory diseases, including asthma, arthritis, and psoriasis, where it may contribute to the progression of inflammation. Researchers are exploring its pathways to develop targeted therapies that can modulate its effects in these conditions. Additionally, LTB3 is of interest in lipid metabolism studies due to its relationship with fatty acids, particularly in understanding how lipid mediators influence cellular processes.
