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)
A 76-year-old man was treated with bilateral orchiectomy, estramustine phosphate and pelvic irradiation for prostate cancer. Osteogenic sarcoma of the prostate developed 18 months after the treatment. Postmortem examination revealed that the tumor was 8 cm in diameter and had infiltrated into the bladder and rectal walls and had resulted in peritoneal(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)
Cluster of differentiation 69 (CD69) has been identified as a lymphocyte early activation marker, and recent studies have indicated that CD69 mediates intracellular signals and plays an important role in various inflammatory diseases. Cigarette smoke (CS) is a strong proinflammatory stimulus that induces the release of proinflammatory mediators by(More)
Excessive apoptosis and prolonged inflammation of alveolar cells are associated with the pathogenesis of pulmonary emphysema. We aimed to determine whether CD40 affects alveolar epithelial cells and endothelial cells, with regard to evoking apoptosis and inflammation. Mice were repeatedly treated with agonistic-anti CD40 antibody (Ab), with or without(More)
Objective Pulmonary nocardiosis frequently develops as an opportunistic infection in patients with malignant tumor and is treated with steroids. This study was performed to clarify the clinical features of pulmonary nocardiosis in Japan. Methods The patients definitively diagnosed with pulmonary nocardiosis at our hospital between January 1995 and December(More)
