Abstract

Chronic obstructive pulmonary disease (COPD) is characterized by a progressive airway obstruction that is not completely reversible and is mainly caused by smoking tobacco. COPD is a major cause of morbidity and mortality worldwide and there are currently no proven effective treatments. The pathogenesis of COPD involves several factors such as chronic inflammation, oxidative stress, and apoptosis. Cytokines play important roles in chronic inflammation. Thalidomide (Thal) has been used to treat multiple myeloma due to its inhibitory effects on IL-6-induced cell growth. We recently demonstrated that thalidomide (Thal) played important roles in cytokine-induced lung damage in a bleomycin-induced pulmonary fibrosis model in mice. We herein examined the preventative effects of Thal on cigarette smoke extract (CSE)-induced emphysematous changes in mice. We performed histological examinations and quantitative measurements of the expression of IL-1β and IL-6 mRNA, as well as apoptosis in CSE-induced mouse lung tissues treated with or without Thal. The results of the histological examination showed that Thal ameliorated CSE-induced emphysema in mice. It also inhibited the expression of IL-1β and IL-6 mRNA in mouse lung tissues. Thal dec...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Castleman Disease

Castleman disease is a rare disorder that involves an overgrowth of cells in the lymph nodes. Unicentric Castleman disease affects one lymph node, usually in the chest or abdomen. Multicentric Castleman disease affects multiple lymph nodes, commonly located in the neck, collarbone, underarm and groin areas. Discover the latest research on Castleman disease here.
