brefeldin a/inflammation

Keratinocytes may play an important role in the pathogenesis of inflammatory skin diseases. Brefeldin A has been shown to attenuate the production and secretion of chemical mediators involved in inflammation and immune responses. However, the effect of brefeldin A on the TNF-α-stimulated production

Cardiovascular disease (CVD) is the leading cause of death in the United States. Diet influences risk factors associated with CVD and atherosclerosis, a major vascular disease that arises from inflammation. Lunasin, a peptide derived from plant foods such as soybeans, contains a unique Arg-Gly-Asp

Staphylococcus aureus, one of the most important pathogens, is heavily associated with allergy. S. aureus and its toxins interact with eosinophils through CD48, a GPI-anchored receptor important in allergy mainly as expressed by the eosinophils (mCD48). CD48 can exist in a soluble form (sCD48). Our

OBJECTIVE Brefeldin A, an antibiotic with effects on certain intracellular compartments, was tested on murine secondary AA amyloidosis. Effects on splenic proteoglycan metabolism were analyzed along with plasma serum amyloid A (SAA) levels. METHODS Brefeldin A was administered daily to mice

IL-6 and IL-23 are both pleiotropic cytokines involved in the regulation of the immune response, inflammation, and hematopoeisis. They also could mediate effector cells and tolerance mediated by cells with regulatory function. Inflammatory bowel disease (IBD) is associated with a reduced ratio of

Regulatory B cells (Breg) are a distinct B cell subset, which contribute to the pathogenesis of autoimmune disorders. Interleukin-10 (IL-10) plays a pivotal function to Breg. It is well described in adults but little is known in a pediatric population. This study was to investigate the role of

Extracorporeal photopheresis (ECP) has been shown to be clinically effective in the treatment of many T cell-mediated conditions. ECP's mechanism of action includes the induction of apoptosis and the release of pro-inflammatory cytokines. Recently, we have observed early lymphoid apoptosis,

We identified the presence of AIF-1 (allograft inflammatory factor-1) in human peripheral blood mononuclear cells (PBMCs) from normal subjects by immunocytological methods. After isolation of different types of mononuclear cells by FACS (Fluorescence-activated cell sorting) with >95% purity, we

Multiparameter flow cytometry was used to examine the cytokine responses of antigen-specific T lymphocytes isolated from the lungs of antigen-sensitized mice which developed pulmonary inflammation after aerosol challenge with ovalbumin (OA) (OA/OA). Lung T cells were stimulated in vitro with OA and

We have recently demonstrated that primary cultured rat pneumocytes produce macrophage inflammatory protein-2 (MIP-2) in response to lipopolysaccharide (LPS) stimulation. In this study, we found that brefeldin A, by blocking anterograde transport from the endoplasmic reticulum (ER) to the Golgi

We compared the patterns of the pro-inflammatory cytokines, interferon-gamma (IFN-gamma), interleukin-2 (IL-2) and tumor necrosis factor-alpha (TNF-alpha), and the anti-inflammatory cytokines, interleukin-10 (IL-10) and tumor growth factor-beta (TGF-beta) from peripheral blood of male and female

BACKGROUND Angiopoietin-1 (Ang-1) and Ang-2 act selectively on endothelial cells by engaging the Tunica interna endothelial cell kinase-2 (Tie2) receptor. A soluble form of Tie2 (sTie2) blocks angiopoietin bioactivity. OBJECTIVE The aim of the study was to characterize changes and expression

Sepsis is caused by a dysregulated host inflammatory response to serious infections resulting in life-threatening organ dysfunction. The high morbidity and mortality make sepsis still a major clinical problem. Here, we investigated the roles of Brefeldin A-inhibited guanine nucleotide-exchange

Persistence of intracellular infection depends on the exploitation of factors that negatively regulate the host immune response. In this study, we elucidated the role of macrophage PGE2, an immunoregulatory lipid, in successful survival of Leishmania donovani, causative agent of the fatal visceral

Obesity is accompanied by dyslipidemia, hypoxia, endoplasmic reticulum (ER) stress, and inflammation, representing the major risk factor for the development of insulin resistance (IR) and type 2 diabetes. We modeled these conditions in cultured 3T3-L1 adipocytes and studied their effect on insulin
