AIMS CD69 is an early activation marker in lymphocytes and an important signal transmitter in inflammatory processes. However, its role in acute lung injury (ALI) is still unknown. We used a lipopolysaccharide (LPS)-induced mouse model of ALI to study the role of macrophage-surface CD69 in this condition. MAIN METHODS We investigated bronchoalveolar(More)
One of the mitogen-activated protein kinases, p38, has been found to play a crucial role in various inflammatory responses. In this study, we analyzed the roles of p38α in multiple sclerosis, using an animal model, experimental autoimmune encephalomyelitis (EAE). p38α(+/-) mice (p38α(-/-) showed embryonic lethality) showed less severe neurological signs(More)
CONTEXT There are few short-term mouse models of chronic obstructive pulmonary disease (COPD) mimicking the human disease. In addition, p38 is recently recognized as a target for the treatment of COPD. However, the precise mechanism how p38 contributes to the pathogenesis of COPD is still unknown. OBJECTIVE We attempted to create a new mouse model for(More)
BACKGROUND Cluster of differentiation 69 (CD69), an early activation marker antigen on T and B cells, is also expressed on activated macrophages and neutrophils, suggesting that CD69 may play a role in inflammatory diseases. To determine the effect of CD69 deficiency on bleomycin(BLM)-induced lung injury, we evaluated the inflammatory response following(More)
