The postinjury inflammatory response in the CNS leads to neuronal excitotoxicity. Our previous studies show that a major component of this response, the inflammatory cytokine tumor necrosis factor alpha (TNFalpha), causes a rapid increase in AMPA glutamate receptors (AMPARs) on the plasma membrane

Monocyte/macrophage infiltration to the subendothelial space of arterial wall is a critical initial step in atherogenesis, in which CC chemokine ligand 2 (CCL2)/monocyte chemoattractant protein-1 (MCP-1) is thought to play a key role. This study investigated the effectiveness of phosphodiesterase

Tumour necrosis factor-alpha (TNF-alpha) is a mediator with a likely role in chronic airway inflammation and airway hyperresponsiveness. In the present study, mouse tracheal segments were cultured for 1, 4 or 8 days in the absence and presence of TNF-alpha. Contractile response of cultured segments

Sodium 4-phenylbutyrate (4-PBA) has attracted a great deal of attention in cystic fibrosis (CF) pathology due to its capacity to traffic DeltaF508-cystic fibrosis transmembrane conductance regulator (CFTR) to the cell membrane and restore CFTR chloride function at the plasma membrane of CF lung

Gap junction channels form the basis of intercellular communication in the heart. In the working myocardium, the connexin43 (Cx43) is most abundantly found, whereas connexin40 (Cx40) is expressed in the atria and in the conduction system [together with low levels of connexin45 (Cx45)]. However,

Endothelial progenitor cells (EPCs) dysfunction is closely correlated with the coronary artery injury induced by Kawasaki disease (KD). The level of tumor necrosis factor-α (TNF-α) elevated significantly in acute phase of KD which can damage the functions of EPCs. The aim of this study was to

The flavonoids, baicalin (5,6-dihydroxy-2-phenyl-4H-1-benzopyran-4-one-7-O-d-β-glucuronic acid) 1 and its aglycone, baicalein 2 are found in edible medicinal plants, Scutellaria baicalensis Georgi and Oroxylum indicum (L.) Kurz in abundant quantities. The antioxidant and anti-inflammatory effects of

Bacterial lipopolysaccharide and other immunostimulants induce gene expression of an isoform of nitric oxide synthase (iNOS) in vascular smooth muscle cells. This process is dependent on nuclear factor-kappa B (NF-kappa B) activation. The aim of this study was to investigate whether the NF-kappa B

We have found previously that phosphatidic acid (PA) can induce inflammatory mediators such as cytokines, which implies that PA plays a role in inflammatory response. In the present study, we provide evidence of the PA-mediated activation of the Janus tyrosine kinase (JAK)-signal transducer and

Macrophages release cytokines that may contribute to the chronic inflammation observed in pulmonary conditions such as asthma and chronic obstructive pulmonary disease. Thus, inhibition of macrophage cytokine production may have a therapeutic benefit. Human lung macrophages are a rich source of the
