Tumor necrosis factor is a potent agent possessing diverse biological functions. We investigated the effects of intravenous administration of human recombinant tumor necrosis factor (TNF) on immune cell populations in CBA/J mice. The animals developed a significant lymphopenia and neutrophilia both reaching a maximum at 4 hours post-injection with a trend towards resolution to normal values by ...

It is well known that tumor necrosis factor (TNF) can have both contrary and pleiotropic effects in anti-tumor immune response. In the present study, we prepared two different tumor cell-based immunotherapy models: MCA38 adenocarcinoma and GL261 glioma intracranial interleukin-2 (IL-2)-based. Each tumor was transfected to express IL-2 with or without expression of the soluble form of tumor necr...

background: tumor necrosis factor alpha (tnf-α) is a primary mediator of immune regulation and might be required in the early stages of dc development from cd34+ cells. however, details of optimal timing of exposure to tnf-α in dc development process in monocytes or non-purified hematopoitic cells are still lacking and clear benefits of this approach to the development of dcs remain to be valid...

The expression of Triggering Receptor Expressed on Myeloid cells ( TREM)-1 has been described as a predictive marker for anti-Tumor Necrosis Factor (TNF)-? monoclonal antibody (mAb) therapy responsiveness in patients with inflammatory bowel disease (IBD). Here we investigated TREM-1 specifically CD14+ monocytes relation to anti-TNF response. pretreatment levels Crohn’s (CD) were outcome mAb the...

Oral administration of the perilla leaf extract (PLE) to mice inhibits inflammation, allergic response, and tumor necrosis factor-alpha production. We also found that PLE suppressed the tumor necrosis factor-alpha (TNF-alpha) production in vitro. Using the inhibitory activity of TNF-alpha production in vitro as the index for isolation, we searched the active constituents from PLE and isolated l...

PURPOSE. Previous studies have suggested no role for tumor necrosis factor (TNF)-a in the modulation of apoptosis in corneal fibroblasts. However, recent investigations have demonstrated that nuclear factor (NF)-kB activation by TNF-a mediates negative apoptotic effects that must be blocked to unmask the apoptotic effects of TNF-a in vitro. The purpose of this study was to investigate the role ...

Abstract Objective Acute lung injury (ALI) is characterized by inflammation and oxidative stress. Nuclear factor-kappaB (NF-κB) mediates the expression of various inflammation-related genes, including NADPH oxidase family. This study aimed to identify potential regulatory role NF-κB on oxidases in tumor necrosis factor-α (TNF-α)-induced stress human alveolar epithelial cells. Methods A549 cells...

BP: Bullous pemphigoid TNF-a: tumor necrosis factor-alfa INTRODUCTION Ustekinumab, a monoclonal antibody that blocks interleukin-12 and interleukin-23, is a biological therapy used to treat moderate-to-severe psoriasis. Bullous pemphigoid (BP) induced by antietumor necrosis factor-alfa (TNF-a) agents has been described in the literature. No cases have been reported with ustekinumab. We report a...

TNF-alpha released from ischemic heart after acute MI increases the production of other cytokines such as interleukin-1 (IL-1), interleukin-6 (IL-6) and adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1). Activation of nuclear factor kappa B (NF-kappa B) by TNF-alpha , up-regulates the expression of molecules which are involved in inflammation and cell adhesion. For these rea...

Background: Tumor necrosis factor- a (TNF-α) is a cytokine that was identified as a factor with a wide range of proinflammatory activities. The expression of bovine TNF-α in mammary tissue during pregnancy seems to have a role in development of the corresponding glands.Objective: Single nucleotide polymorphisms (SNPs) were defined in 3′-flanking region of...
