| Leukotriene B5 is hardly detectable in human neutrophils, but is produced in the subjects fed with 5,8,11,14,17-eicosapentaenoic acid Prescott_SM et al.. | |
Corey_EJ et al.  | |
| Leukotriene B5 is produced via leukotriene A5 from 5,8,11,14,17-eicosapentaenoic acid, which is almost as active as arachidonic acid as substrate Yamamoto_S . | |
| Leukotriene B5 is about 1/30 as active as leukotriene B4 in stimulating aggregation of rat neutrophils, migration and lysosomal enzyme release of human polymorphonuclear leukocytes, and bradykinin-induced vascular permeability Terano_T et al.. Leukotriene B5 is much less active than B4 to increase intracellular calciuim level in human neutrophils Seya_A et al.. | |
