We propose a novel role for interleukin (IL) 6 in inducing rapid spontaneous proliferation (SP) of naive CD8(+) T cells, which is a crucial step in the differentiation of colitogenic CD8(+) T cells. Homeostasis of T cells is regulated by two distinct modes of cell proliferation: major histocompatibility complex/antigen-driven rapid SP and(More)
Sensitivity of neurons to estrogen in down-regulation of estrogen receptor alpha (ERalpha) can be thought to make a sex difference in regulatory system of reproductive activities. In this study, to investigate the sex difference of expression of ERalpha in the hypothalamus and midbrain, the number of ERalpha immunoreactive (-ir) cells was counted in(More)
Prior studies have shown that transfer of ovalbumin (OVA)-specific T helper type 1 (Th1) cells into mice bearing MHC class II+ OVA-expressing tumor cells (A20-OVA) causes complete tumor rejection. Here we show that, although Th1 cell therapy alone was not effective against MHC class II- OVA-expressing tumor cells (EG-7), treatment of mice bearing(More)
This paper introduces the TORISHIKI-KAI project, which aims to construct a million-word-scale semantic network from the Web using state of the art knowledge acquisition methods. The resulting network can be browsed as a Web search directory, and we show that the directory is useful for finding “unknown unknowns” — in the infamous words of D.H. Rumsfeld:(More)
Trials on transmitting olfactory information together with audio/visual information are currently being conducted in the field of multimedia. However, continuous emission of scents creates problems of olfactory adaptations and scents lingering in the air. To overcome these problems, we developed an ink-jet olfactory display. This display has high emission(More)
www.eg.org diglib.eg.org Abstract Studies aiming at increasing the sense of reality by using scents with the picture medium, such as movies, have lately attracted much attention. In the picture medium, multiple objects with different scents are seen at the same time. Therefore, it is thought that by controlling the presentation of scent in accordance with(More)
Cancer-testis (CT) antigens were identified as a group of highly attractive targets for cancer immunotherapy because of their expression in a variety of malignant tumors but solely in the testis among the normal adult tissues. To evaluate the potential of two members of this family, MAGE-A4 and NY-ESO-1 antigens, for cancer vaccine in non-small cell lung(More)
Naive CD4(+) T cells rapidly proliferate to generate effector cells after encountering an antigen and small numbers survive as memory T cells in preparation for future immunological events. In the present work, adoptive transfer of naive CD4(+) T cells into RAG2(-/-) mice caused the generation of memory-type effector T cells including T(h)1, T(h)2, T(h)17(More)
Peptide-MHC tetramers have been engineered to allow accurate detection of antigen-specific cytotoxic C lymphocytes (CTL) by flow cytometry. Here, we propose a novel use for peptide-MHC tetramers in the specific and sensitive analysis of the cytotoxic function of antigen-specific CTL by blocking MHC-restricted antigen-specific cytotoxicity. We found that(More)
We have evaluated the capacity of a novel, nanoparticle-based tumor vaccine to eradicate established tumors in mice. C57BL/6 mice were intradermally (i.d.) inoculated with ovalbumin (OVA)-expressing EG-7 tumor cells. When the tumor size reached 7-8 mm, the tumor-bearing mice were i.d. injected near the tumor-draining lymph node (DLN) with liposomes(More)
