CD14, a high-affinity receptor for lipopolysaccharide (LPS), is a glycoprotein expressed on the surface membranes of monocytes/macrophages. We have identified a previously unknown form of soluble CD14, named soluble CD14 subtype (sCD14-ST), that is increased in patients with sepsis. To measure sCD14-ST concentrations in plasma, we prepared anti-sCD14-ST(More)
We previously reported an orally active anti-allergic agent, M50367, modulated Th1/Th2 balance to down-regulate Th2 response in a murine model of atopic asthma. In this study, we examined the effect of M50354, the active metabolite of M50367, on the differentiation of naïve Th cells into Th1/Th2 cells. M50354 at 3 microM decreased the generation of Th2(More)
A cell line designated RMG-II was established from the ascites of a patient with ovarian clear cell carcinoma. The chromosomal analysis revealed aneuploidy with a hypertetraploid modal number and 8 marker chromosomes. Radioimmunoassay and immunocytochemical staining showed that RMG-II cells produced some tumor markers such as CA125 and TPA. Two monoclonal(More)
We examined a relationship between p21WAF1/CIP1/SDI1 and cell-cycle-related proteins in 12 human liver tumor cell lines (JHH-1, -2, -4, -5, -6, -7; HLE; HuH-7; Hep3B; PLC/PRF/5; HuH-6; HepG2). Seven (JHH-1, -2, -5, -6, -7; Hep3B; HepG2) out of eight cell lines having p21WAF1/CIP1/SDI1 protein overexpressed cyclin E protein, although one of them (JHH-5)(More)
An orally active antiallergic agent, M50367, skews the Th1/Th2 balance toward Th1 dominance by suppressing naive Th cell differentiation into Th2 cells in vitro. Administration results in the suppression of IgE synthesis and peritoneal eosinophilia in vivo. In this report, we determined that M50354 (an active metabolite of M50367) was a ligand for the aryl(More)
Platelet adhesion to vascular subendothelium, mediated in part by interactions between collagen and glycoprotein VI (GPVI) complexed with Fc receptor gamma-chain, is crucial for thrombus formation. Antiplatelet therapy benefits patients with various thrombotic and ischemic diseases, but the safety and efficacy of existing treatments are limited. Recent data(More)
Sepsis occurs when microbes activate toll-like receptors (TLRs) stimulating widespread inflammation and activating coagulation cascades. TLR4 signal transduction has been recognized as a key pathway for lipopolysaccharide (LPS)-induced activation of various cells and an attractive target for treatment of sepsis. We found a new benzisothiazole derivative,(More)
Glycoprotein VI (GPVI) plays a critical role in the platelet response to collagen. Clinical studies suggest that the plasma level of soluble GPVI (sGPVI) is a highly specific and useful platelet activation marker. However, many properties of sGPVI have not been fully characterized, such as its sensitivity in detecting platelet activation and its elimination(More)
