    Potential involvement of Fas and its ligand in the pathogenesis of Hashimoto's thyroiditis (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1997-02-14
    Beschreibung: The mechanisms responsible for thyrocyte destruction in Hashimoto's thyroiditis (HT) are poorly understood. Thyrocytes from HT glands, but not from nonautoimmune thyroids, expressed Fas. Interleukin-1beta (IL-1beta), abundantly produced in HT glands, induced Fas expression in normal thyrocytes, and cross-linking of Fas resulted in massive thyrocyte apoptosis. The ligand for Fas (FasL) was shown to be constitutively expressed both in normal and HT thyrocytes and was able to kill Fas-sensitive targets. Exposure to IL-1beta induced thyrocyte apoptosis, which was prevented by antibodies that block Fas, suggesting that IL-1beta-induced Fas expression serves as a limiting factor for thyrocyte destruction. Thus, Fas-FasL interactions among HT thyrocytes may contribute to clinical hypothyroidism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giordano, C -- Stassi, G -- De Maria, R -- Todaro, M -- Richiusa, P -- Papoff, G -- Ruberti, G -- Bagnasco, M -- Testi, R -- Galluzzo, A -- A.066/Telethon/Italy -- New York, N.Y. -- Science. 1997 Feb 14;275(5302):960-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, Endocrinology Section, Institute of Clinica Medica, University of Palermo, Palermo, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9020075" target="_blank"〉PubMed〈/a〉

    Requirement for CD8+ cells in T cell receptor peptide-induced clonal unresponsiveness (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1993-01-01
    Beschreibung: T cell receptor (TCR) vaccination in rats prevents the development of experimental allergic encephalomyelitis (EAE), an animal model of multiple sclerosis. The mechanism of this potential immunotherapy was examined by vaccinating mice with an immunogenic peptide fragment of the variable region of the TCR V beta 8.2 gene. Another immunogen that usually induces an immune response mediated by V beta 8.2+ T cells was subsequently inhibited because specific clonal unresponsiveness (anergy) had been induced. Depletion of CD8+ cells before TCR peptide vaccination blocked such inhibition. Thus, the clonal anergy was dependent on CD8+ T cells, and such immunoregulatory T cells may participate in the normal course of EAE.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gaur, A -- Ruberti, G -- Haspel, R -- Mayer, J P -- Fathman, C G -- AI 27989/AI/NIAID NIH HHS/ -- DK 39959/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1993 Jan 1;259(5091):91-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8418501" target="_blank"〉PubMed〈/a〉
