Leukotriene B4 is essential for lung host defence and alpha-defensin-1 production during Achromobacter xylosoxidans infection

Abstract: Leukotriene B4 (LTB4) is essential for host immune defence. It increases neutrophil recruitment, phagocytosis and pathogen clearance, and decreases oedema and inflammasome activation. The host response and the role of LTB4 during Achromobacter xylosoxidans infection remain unexplored. Wild-type (129sv) and LTB4 deficient (Alox5 −/−) mice were intratracheally infected with A. xylosoxidans. Wild-type 129sv infected mice survived beyond the 8th day post-infection, exhibited increased levels of LTB4 in the lung on… Show more

“…Importantly, LTB 4 production is not dependent on transcriptional regulation (29). Therefore, LTB 4 is produced more rapidly than other chemoattractants, such as IL-8, and it is pivotal in mounting a swift inflammatory response (26,28,(30)(31)(32). Moreover, release of LTB 4 is independent of degranulation (33), suggesting that regulation of LTB 4 release also differs from degranulation.…”

“…Resultados prévios do nosso grupo demonstraram que a infecção por A. xylosoxidans induz produção PGE 2 no sétimo dia após a infecção, e LTB 4 no primeiro dia após a infecção nos pulmões. LTB 4 é essencial para a síntese de alfa-defensina, peptídeo antimicrobiano que auxilia no clearance do bacilo nos pulmões [55]. Em nosso trabalho, observamos que animais deficientes de CD14 ou TLR4 produzem menos LTB 4 nos pulmões, quando comparados com camundongos selvagens.…”
