Varying susceptibility of pulmonary cytokine production to lipopolysaccharide in mice.

Abstract

Objectives: The lipopolysaccharide (LPS)-induced acute lung injury (ALI) model has been widely applied for pathophysiological and pharmacological research. The aim of present study is to understand the variation of acute pulmonary inflammation between mouse strains. Methods: The present study investigated the susceptibility of acute production of inflammatory mediators, e.g. cytokines, chemokines and others, to LPS in C57BL/6J, Balb/cJ, DBA/1J, CD-1, NMRI, DBA/2J, A/J, and C3H/HeN mice. Results: The susceptibility to intra-tracheal challenge with LPS varied between measured variables, durations and strains. General lung hyper-reactive susceptibility to LPS-induced pulmonary production of 6-8 inflammatory mediators followed the order NMRI, Balb/cJ, C3H/HeN, A/J, C57BL/6J, DBA/1J, DBA/2J and CD-1 mice at 4h, and A/J, C3H/HeN, CD-1, NMRI, C57BL/6J, Balb/cJ, DBA/2J and DBA/1J mice at 24h. Conclusions: Our data provide information for scientists to consider the proper strain of mice for the measurement of specific inflammatory mediators and to select sensitive or resistant mouse strains for understanding genetic variation in the pathogenesis and for the screening of target-oriented drug development.
