The leukotriene products of the 5-LOX pathway, are important in the inflammation process as they are well-known for the recruitment of infiltrating inflammatory species such as neutrophils and leukocytes (Serhan, Jain et al. 2003, Sadik, Sezin et al. 2013).
The 5-LOX enzyme requires the FLAP protein to be active in the cell, to produce 5-HETE and LTA4.
