Prevention of encephalomyocarditis virus-induced diabetes in mice by inhibition of the tyrosine kinase signalling pathway and subsequent suppression of nitric oxide production in macrophages.

Nitric Oxide Production in Macrophages Pathway and Subsequent Suppression of Inhibition of the Tyrosine Kinase Signalling Virus-Induced Diabetes in Mice by Prevention of Encephalomyocarditis

Role of Hck in the pathogenesis of encephalomyocarditis virus-induced diabetes in mice.

Soluble mediators such as interleukin-1beta, tumor necrosis factor alpha (TNF-alpha), and inducible nitric oxide synthase (iNOS) produced from activated macrophages play an important role in the destruction of pancreatic beta cells in mice infected with a low dose of the D variant of encephalomyocarditis (EMC-D) virus. The tyrosine kinase signaling pathway was shown to be involved in EMC-D viru...

Src family kinases participate in the regulation of encephalomyocarditis virus-induced cyclooxygenase-2 expression by macrophages

Src family kinases (SFKs) are non-receptor tyrosine kinases that have been implicated as regulators of the inflammatory response. In this study, the role of SFK activation in the inflammatory response of macrophages to encephalomyocarditis virus (EMCV) infection was examined. Virus infection of macrophages stimulates the expression of cyclooxygenase-2 (COX-2), interleukin (IL)-1beta and inducib...

Kinetics of Nitric Oxide Production and MTT Reduction by HSV-1 Infected Macrophages

Background: Macrophages have important role in defense against Herpes Simplex Virus type-1 (HSV-1). The present study was performed to determine the viability and nitric oxide (NO) production by HSV-1 infected mouse peritoneal macrophages (HIM). Method: The viability of macrophages was evaluated using MTT reduction assay and the production of nitrite using Griess method. Results: The ability of...

Thiazolidinedione Derivative Suppresses LPS-induced COX-2 Expression and NO Production in RAW 264.7 Macrophages

The present study was designed to investigate the inhibitory effect of 2,4 bis-[(4-ethoxyphenyl)azo] 5-(3-hydroxybenzylidene) thiazolidine-2,4-dione (TZD-OCH2CH3) on the cyclo-oxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in RAW 264.7 cells. The effects of TZD-OCH2CH3 on COX-2 and iNOS mRNA expression in LPS-activated RAW 264.7 cells ...
