Previous studies have suggested that CCR4 is particularly important in the selective recruitment of various subsets of leucocytes in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). In this study, we examined the percentage of CD4(+)/CCR4(+) T cells within circulating lymphocytes in active ankylosing spondylitis (AS), RA and SLE patients.(More)
We investigated the changes in percentages of leukocyte subpopulations, natural killer (NK) cells, CD69-expressing lymphocytes, and psychological aspects in 10 subjects who participated in a 10-day confinement study. Suppression of lymphocyte proliferative reaction and changes in leukocyte distribution are known to occur in space. These responses are(More)
The acetylesterase (AE) activity of DVIM (diarrhea virus of infant mice) was assigned to the haemagglutinin-esterase (HE) protein. The substrate specificity was examined using the natural substrate bovine submaxillary mucin (BSM) and/or synthetic substrates p-nitrophenylacetate (p-NiA) and α-naphthylacetate (α-NA) and compared with several strains of MHV(More)
Microglia survey the brain environment by sensing several types of diffusible molecules, among which extracellular nucleotides released/leaked from damaged cells have central roles. Microglia sense ATP or other nucleotides by multiple P2 receptors, after which they change into several different phenotypes. However, so far, it is largely unknown whether(More)
Interleukin-12 (IL-12) is a monocyte/macrophage-derived cytokine that plays a prominent role in the development of T helper type 1 (Th1) cell-mediated immune responses. Glycyrrhizin (GL), an aqueous extract of liquorice root, used as Chinese medicine, is known to have various immunomodulating activities. In this study, GL showed a dose-dependent priming(More)
IL-7 plays a critical role in B cell fate decision by regulating early B cell factor (EBF) expression. However, it was not clear when IL-7 stimulation is necessary in hemato-/lymphopoiesis in adult mice. Here we show that pre-proB cells derived from IL-7-/- mice have lost B cell potential, despite up-regulation of EBF expression following IL-7 stimulation.(More)
We analyzed the characteristics of seven monoclonal antibodies (mAbs) raised against purified HE (hemagglutinin-esterase) glycoprotein of the murine coronavirus DVIM (diarrhea virus of infant mice). Immunocrossreaction of these mAbs with JHM and/or MHV-S suggest that antigenic epitopes of HE of DVIM are similar to those of JHM and/or MHV-S. Four mAbs (1b4,(More)
We examined the effects of hemicellulase-treated Agaricus blazei (AB fraction H, ABH) on growth of several tumor cell lines. ABH inhibited the proliferation of some cell lines without cytotoxic effects. It markedly prolonged the S phase of the cell cycle. ABH also induced mitochondria-mediated apoptosis in different cell lines. However, it had no impact on(More)
Tricho-rhino-phalangeal syndrome Type III (TRPS III) is a newly defined genetic entity. Only 9 patients in a family and one sporadic patient have been reported. We add another family in which 4 individuals in 3 generations are affected with this autosomal dominant trait. Although they manifested short stature, sparse hair, "pear-shaped" nose, and(More)
