Toxic products produced by macrophages
Webproduced by activated CD4+ T helper (Th) 1 cells, CD8+ T cytotoxic 1 cells, and natural killer cells, and converts rest-ing macrophages into potent cells with enhanced antigen– … WebLeukotrienes are perhaps the best studied macrophage-produced mediators involved in the pathogenesis of asthma. The role of macrophage-derived leukotrienes remains uncertain. Cysteinyl leukotrienes (LTC4, D4, and E4) are minor products of AMs when compared to LTB4 production [51, 53, 113]. This metabolic profile argues against a role for AMs in ...
