A cDNA sequence coding for a unique mouse interleukin that expresses B-cell-, T-cell, and mast-cell-stimulating activities has been isolated from helper T-cell library. The library, constructed in the pcD expression vector, was screened by transfecting COS monkey cells with DNA pools to express products encoded full-length inserts. By assaying transfected cell supernatants, we identified clones encoding factor stimulates mast lines. This also induces Ia on resting B enhances IgG1 IgE...

A cDNA sequence coding for a human interleukin has been isolated from concanavalin A-activated T-cell library based on homology with mouse that expresses B-cell stimulatory factor 1 (BSF-1) activity and T-cell- mast-cell-stimulating activities. The contains single open reading frame encoding protein of 153 amino acid residues including putative signal peptide. Amino sequences the polypeptides, deduced their cDNAs, share extensive exception about 40 near middle portion, which little homology....

A cDNA sequence coding for a human granulocyte-macrophage colony-stimulating factor has been isolated from libraries prepared mRNA derived concanavalin A-activated T-cell clones. The constructed in the pcD vector system were screened by transfecting COS-7 monkey cells with DNA pools to express products encoded full-length inserts. By assaying cell supernatants, we identified clones encoding that stimulates formation of granulocyte and macrophage colonies progenitor cells. These results...

Objective. Systemic lupus erythematosus (SLE) in a multisystem autoimmune disorder characterized by multiorgan pathology and autoantibodies against variety of autoantigens. The CD28 CTLA‐4 genes might be candidate for SLE, because costimulation signals from CD80/CD86 to CD28/CTLA‐4 have been suggested play an important role the activation or inactivation T lymphocytes. Methods. We investigated three polymorphic regions within gene, C/T base exchange promoter region −318 (CTLA‐4 −318C/T), A/G...

Objectives. The possible link between LEF and interstitial lung disease (ILD) has evoked increasing concern. aim of the present study was to elucidate prevalence risk factors for newly developed and/or exacerbated ILD, based on post-marketing surveillance data, in which all RA patients receiving were pre-registered monitored 24 weeks Japan. Methods. We analysed data from a cohort 5054 who prescribed since its launch September 2003 Multivariable logistic analysis performed identify...

We have isolated cDNA clones encoding human IL-3 from libraries constructed in a modified pcD mammalian expression vector by using mRNA prepared activated T cell clones. Amino acid sequence of deduced DNA these agrees with that predicted genomic except at amino position 27. Northern blotting analysis and S1 nuclease show almost all express kinetics similar to observed mouse However, striking difference was found the level granulocyte-macrophage-CSF expressed cells. In contrast clones, is...

The complete nucleotide sequences of the 5.8S and 26S rRNA genes Physarum polycephalum transcribed spacer between them were determined. Comparison with those Escherichia coli 23S yeast showed that there are 16 highly homologous regions in E. eukaryotes have some eukaryote-specific extra sequences. sequence immediately following 5.8S-like region was found to be 5' terminus rRNA, indicating gene is derived from 5'-terminal prokaryote large gene.

Monocyte chemoattractant protein-1 (MCP-1) is up-regulated and recruits activates inflammatory cells in human diffuse proliferative lupus nephritis (DPLN) of model MRL/lpr mice. The aim this study was to examine whether anti-MCP-1 gene therapy inhibits the progression mice.An NH(2)-terminal deletion mutant MCP-1 gene, 7ND, injected into skeletal muscles mice with advanced stage blockade its receptor (CCR2) signalling pathway.Histological findings kidneys treated mice, which received more...

Since IL-10 has recently been shown to exhibit pleiotropic effects on human monocytes, it was of interest determine the effect this cytokine prostaglandin E2 (PGE2) production by monocytes. Recombinant (rIL-10) did not significantly affect PGE2 lipopolysaccharide (LPS)-unstimulated but efficiently inhibited LPS-stimulated The inhibition rIL-10 achieved in a dose-dependent manner. IL-4 also at same degree as rIL-10. Viral monocytes similar fashion Endogenously produced inhibit Kinetic studies...

The background and clinical laboratory features were examined compared between who died recovered from it. Results. Among 22 developed injury, 9 13 tended to have pre-existing interstitial pneumonia (8/9 vs 6/13, P = 0.07). loading maintenance doses, serum concentration LEF metabolite A771726 administration period did not differ groups.

Using the urinary 8-hydroxydeoxyguanosine (8-OHdG) concentration, effects of participation in a two-day ultramarathon race period on oxidative DNA damage were investigated Japanese nonprofessional runners. Before first day (baseline), after (mid-race) 40-km running, and second (post-race) 90 km biomaterials successfully sampled from 95 participants (males, 79; females, 16) who completed full race. We analyzed urine for 8-OHdG blood aspartate aminotransferase (AST), creatine phosphokinase...

Donor-specific antibodies (DSAs) are the main cause of graft loss over time. The direct pathway alloantigen recognition is important in pathogenesis acute rejection. Recent studies have suggested that also contributes to chronic injury. Nevertheless, there no reports on T-cell response via kidney recipients with DSAs. We analyzed DSAs (DSA+) or without (DSA−). A mixed lymphocyte reaction assay was implemented assess response. DSA+ patients showed significantly higher CD8 + and CD4 T cell...

Human immune response can be classified into 2 different subsets of T helper cells (Th1 and Th2) based on the pattern cytokine production. In modern immunology, Th1/Th2 paradigm helps to explain inflammatory effector pathways outcomes in human diseases. The present study was designed determine type immunological that influences anti-neutrophil cytoplasmic antibody-(ANCA) associated glomerulonephritis (GN) using analysis peripheral diseased kidney tissues.We analyzed blood ratio 91 patients...

Abstract We introduce a microrubbing process using small hot stylus to create liquid crystalline (LC) polymer possessing microscale thread-like structure with good molecular orientation properties. In this process, the spin-coated thin film was rubbed apply lateral shear force and induce LC phase. The effects of line thickness (or created thread spacing) on processing temperature vertical load were studied construct formation model threads. Furthermore, regular arrangement threads, which can...
