We examined the dynamics of removal from circulation, tissue distribution, and persistence of phosphorothioate oligodeoxynucleotides (S-ODN) anti-tumor-necrosis-factor and a control of random sequence (randomer) in mice. After intravenous injection, the majority (96%) of S-ODN cleared rapidly from the circulation in the first two phases. In the first phase,(More)
Human immunoglobulin (Ig)A exists in blood as two isotypes, IgA1 and IgA2, with IgA2 present as three allotypes: IgA2m(1), IgA2m(2), and IgA2m(n). We now demonstrate that recombinant, chimeric IgA1 and IgA2 differ in their pharmacokinetic properties. The major pathway for the clearance of all IgA2 allotypes is the liver. Liver-mediated uptake is through the(More)
BACKGROUND Profiling of gene expression in healthy and diseased renal tissue is important for elucidating the pathogenesis of renal diseases. Comprehensive information about the genes expressed in renal tissue is unavailable. The recently developed cDNA array hybridization methodology allows simultaneous monitoring of thousands of genes expressed renal(More)
To identify the cytokines that play a relevant role in the pathogenesis of IgA nephropathy, we analyzed and compared the gene expression of proinflammatory cytokines, immuno-regulatory cytokines, and growth factors in peripheral blood mononuclear cells (PBMC). Expression of IL-1 alpha, IL-1 beta, IL-2, IL-4, IL-6, IL-10, IL-12, IFN-gamma, TGF-beta,(More)
Clinical episodes of IgA nephropathy coincide recurrently with microbial infections. Cytokines produced during such infections may play a role in the pathogenesis of IgA-associated glomerulonephritis. To test this hypothesis, we examined the influence of passively administered proinflammatory cytokines (IL-1, IFN-gamma and IL-6) on the development of(More)
Leukotrienes (LT) of the 5-lipoxygenase pathway constitute a class of potent biological lipid mediators of inflammation implicated in the pathogenesis of different models of experimental glomerulonephritis. The key enzyme, 5-lipoxygenase (5-LO), catalyses oxygenation of arachidonic acid to generate the primary leukotriene LTA4. This LT, in turn, serves as a(More)
BACKGROUND/AIMS A comprehensive profile of genes expressed at the mRNA level (transcriptome) in human liver tissue is important for elucidating the pathogenesis and treatment of hepatic diseases. The recent development of cDNA array hybridization allows the parallel monitoring of thousands of genes expressed in a single organ. METHODS High-density(More)
1a,25-Dihydroxyvitamin D3 [1,25(OH)2D3], the hormonal form of vitamin D3, has been shown to play a role in the regulation of growth of the regenerating adult rat liver following partial hepatectomy. In addition, a recent study implicated the neonatal liver as a possible extrarenal site of 1,25(OH)2D3 synthesis. Therefore, in our present study we used(More)
