Suppression of tumor necrosis factor-alpha-induced neutrophil adherence responses by essential oils.
BACKGROUND In aromatherapy, essential oils are used as anti-inflammatory remedies, but experimental studies on their action mechanisms are very limited. AIMS To assess their anti-inflammatory activities, effects of essential oils on neutrophil activation were examined in vitro. METHODS Neutrophil activation was measured by tumor necrosis factor-alpha (TNF-alpha)-induced adherence reaction o...
Vasoactive intestinal peptide (VIP) is an anti-inflammatory immunomodulatory neuropeptide with therapeutic potential demonstrated for collagen-induced arthritis. The aim of this study was to characterise its potential anti-arthritic effect on human monocytes, macrophages, T cells, and rheumatoid arthritis synovial membrane cells. Monocytes, macrophages, and T cells derived from human peripheral...
Tumor necrosis factor alpha (TNF-alpha) is overexpressed during human immunodeficiency virus (HIV) infection. RP 55778, a TNF-alpha synthesis inhibitor, decreases HIV replication in monocytes/macrophages. Therapeutic use of RP 55778 in vivo, like that of other biological response modifiers, would theoretically require association with dideoxynucleosides. We have evaluated here the combinatory e...
Lipopolysaccharide (LPS) stimulates peripheral mononuclear cells (PBMC) to synthesize or release pyrogenic cytokines, including interleukin-1beta (IL-1beta), IL-6, and tumor necrosis factor-alpha (TNF-alpha). Nuclear factor-kappa B (NF-kappaB) influences inflammatory responses through the regulation of genes encoding cytokines. In the present study, experiments were carried out to determine whe...
Tumor necrosis factor alpha (TNF-α) expression amplifies to excess amounts in several disorders such as rheumatoid arthritis and psoriasis. Although, Anti-TNF biologics have revolutionized the treatment of these autoimmune diseases, formation of anti-drug antibodies (ADA) has dramatically affected their use. The next generation antibodies (e.g. Fab, scFv) have not only reduced resulted immunoge...
We studied the potential role of a cytokine regulatory mechanism(s) in LPS-dependent reprogramming and modulation of TNF-alpha and nitric oxide (NO) responses in mouse peritoneal macrophages. Reciprocal regulation of TNF-alpha and NO production by LPS-primed and LPS-stimulated macrophages was found to be dependent on the presence of soluble secretory products released by the cells during the in...
OBJECTIVES This study was performed to observe the effects of conditioned media (CM) of cultured mononuclear cells (MNC) on the expression of beta 1 integrin and intercellular adhesion molecule(ICAM)-1 on mesangial cells and the modulation by TGF-beta, TNF alpha, or hydroxyl radical Also these were examined in anti-Thy mesangial proliferative GN (MsPGN) or puromycin aminonucleoside nephrosis(PA...
Epithelial ovarian cancer cells express the chemokine receptor, CXCR4, which may be associated with increased survival and metastatic potential, but the regulation of this receptor is not understood. The inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) is found in ovarian cancer biopsies and is associated with increased tumor grade. In this report, we show that CXCR4 expression on ...
BACKGROUND & AIMS Treatment with tumor necrosis factor (TNF) induces murine hepatocyte apoptosis in vitro and in vivo when sensitizing concentrations of toxins are present. The aim of this study was to investigate whether endogenously formed TNF contributes to liver failure caused by hepatotoxins. METHODS The extent of liver damage, induced by alpha-amanitin or actinomycin D (ActD), was exami...
