Tumour growth depends on angiogenesis, which is closely associated with vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs). Extracellular MMP inducer (EMMPRIN) was reported to involve in the progression of malignancies by regulating expression of VEGF and MMPs in stromal cells. To clarify the role of EMMPRIN in progression and(More)
To evaluate the probiotic, Bifidobacterium breve strain Yakult (BBG-01), for safety and enhancement of immunogenicity in an oral inactivated cholera vaccine, a randomized double-blind placebo-controlled study was performed. Bangladeshi children under 5-year-old received BBG-01 or placebo for 4 weeks with two doses of oral cholera vaccine. Serum/fecal(More)
An oxytocin-vasopressin-related peptide, Cys-Phe-Val-Arg-Asn-Cys-Pro-Thr-Gly-NH2, was isolated from the lumbricid earthworm, Eisenia foetida and termed annectocin. Annetocin potentiated not only spontaneous contractions of the gut but also pulsatory contractions and bladder-shaking movement of the nephridia. Annetocin may be involved in osmoregulation of(More)
Two novel neuropeptides, urechistachykinin I (H-Leu-Arg-Gln-Ser-Gln-Phe-Val-Gly-Ser-Arg-NH2) and urechistachykinin II (H-Ala-Ala-Gly-Met-Gly-Phe-Phe-Gly-Ala-Arg-NH2), were isolated from the ventral nerve cords of the echiuroid worm, Urechis unicinctus. These peptides showed a contractile action on the inner circular body-wall muscle of the animal. Their(More)
In order to expand tumor-infiltrating lymphocytes (TIL) efficiently and in order to use them for immunotherapy, we utilized lipopolysaccharide-activated B cells (LPS blasts) as costimulatory-signal-providing cells in an in vitro culture system. TIL, prepared from subcutaneously inoculated B16 melanoma, failed to expand when cultured with anti-CD3 monoclonal(More)
It is known that Legionella pneumophila proliferates in peritoneal macrophage cultures derived from A/J mice but not in macrophage cultures derived from many other strains, including C57BL/6 mice. To analyze the genetic control of this trait and the location of the Legionella resistance-susceptibility gene, we prepared segregating progeny of A/J and C57BL/6(More)
BACKGROUND The impact of perioperative synbiotics on bacterial translocation and subsequent bacteraemia after oesophagectomy is unclear. This study investigated the effect of perioperative synbiotic administration on the incidence of bacterial translocation to mesenteric lymph nodes (MLNs) and the occurrence of postoperative bacteraemia. METHODS Patients(More)
In a previous study (Y. Koga, M. Sasaki, H. Yoshida, H. Wigzell, G. Kimura, and K. Nomoto, J. Immunol. 144:94-102, 1990), we demonstrated that the expression of gp160, a precursor form of envelope glycoprotein of human immunodeficiency virus type 1, in CD4+ cells causes the downregulation of surface CD4 and single-cell killing by forming intracellular(More)
BACKGROUND Although an immunomodulatory role for estrogens has long been demonstrated by experimental and clinical observations, the mechanism by which estrogens exert their effect on T cells has not been clearly defined. METHODS In this study we analyzed the effects of beta-estradiol (E2), at its contraceptive dose, on the delayed-type hypersensitivity(More)
Fulicin (Phe-D-Asn-Glu-Phe-Val-NH2) is a neuropeptide from ganglia of the African giant snail (Achatina fulica). Previously, the sequences of nine fulicin gene-related peptides (FGRP-1 to -9) have been predicted from the cDNA encoding the ganglia fulicin precursor and the transcripts have been detectable in the heart. We synthesized twenty peptides related(More)
