BACKGROUND Macrophages can differentiate into pro-inflammatory (M1) or anti-inflammatory (M2) phenotypes upon exposure to a pathogen or a cytokine microenvironment. However, M1/M2 macrophage polarization in polymicrobial sepsis has not been fully characterized. METHODS The polarity of peritoneal exudate (PE) cells from mice that had undergone cecal ligation and puncture (CLP) and the response...
OBJECTIVE To elucidate a possible role of cAMP responsive element binding protein (CREB) in rheumatoid arthritis (RA) synovial cell function, we have studied CREB expression of synovial cells and the effects of an inhibitor of the cAMP/CREB signal pathway on synovial cell function in patients with RA. METHODS We examined CREB expression by immunohistochemical staining, immunocytochemical stai...
OBJECTIVE Anti-tumor immunity and cytokine profiles have important roles in the development of cancer. Norepinephrine (NE) release due to sympathetic activation leads to a Th2 deviation via the beta-2 adrenergic receptor Beta-2 adrenergic receptor (β-2AR) and could increase cancer progression. This study intends to determine the effects of isoproterenol (ISO; beta-agonist) and propranolol (PRO;...
BACKGROUND Clonorchis sinensis (C. sinensis) is considered to be an important parasitic zoonosis because it infects approximately 35 million people, while approximately 15 million were distributed in China. Hepatitis B virus (HBV) infection is a major public health issue. Two types of pathogens have the potential to cause human liver disease and eventually hepatocellular carcinoma. Concurrent i...
The protective effect of pregnancy on putative Th1-mediated autoimmune diseases, such as multiple sclerosis and rheumatoid arthritis, is associated with a Th1 to Th2 immune shift during pregnancy. The hormone estriol increases during pregnancy and has been shown to ameliorate experimental autoimmune encephalomyelitis and collagen-induced arthritis. In addition, estrogens induce cytokine changes...
Leading hypotheses to explain helminth-mediated protection against autoimmunity postulate that type 2 or regulatory immune responses induced by helminth infections in the host limit pathogenic Th1-driven autoimmune responses. We tested these hypotheses by investigating whether infection with the filarial nematode Litomosoides sigmodontis prevents diabetes onset in IL-4-deficient NOD mice and wh...
Background & Aims: Shift work is programmed in various schedules, each has its own advantages and disadvantages. The main purposes of this study were: a) to determine common shift schedules used in petrochemical industries, b) to compare shift work health-related problems among employees working in different shift schedules and c) to recommend appropriate shift schedule. Methods: This cross...
