    Homeostasis of the antibody response: immunoregulation by NK cells (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-11-11
    Beschreibung: When injected into mice, the synthetic double-stranded polynucleotide poly(inosinic) X poly(cytidylic) acid induces high natural killer (NK) cell activity within 4 to 12 hours. Induction of NK activity in mice immunized 2 or 3 days previously, or the addition of NK cells to cultures immunized in vitro 2 or 3 days previously, promotes early termination of the ongoing primary immunoglobulin M antibody response. A target for NK cells is a population of accessory cells that has interacted with antigen and is necessary for sustaining the antibody response. The inference is strong that NK cells induced normally by immunization also terminate the usual antibody response in vivo by elimination of antigen-exposed accessory cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abruzzo, L V -- Rowley, D A -- 5-T32-CA-09267/CA/NCI NIH HHS/ -- R01-10242/PHS HHS/ -- New York, N.Y. -- Science. 1983 Nov 11;222(4624):581-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6685343" target="_blank"〉PubMed〈/a〉

    Peptide cotransmitter at a neuromuscular junction (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-07-15
    Beschreibung: The neuropeptide proctolin (H-Arg-Tyr-Leu-Pro-Thr-OH) is present in the nerve terminals of an identified slow skeletal motoneuron in the cockroach. Proctolin is released onto the target muscle, a coxal depressor, by neuron stimulation and by depolarization with potassium. The physiological action of the motoneuron suggests that proctolin acts as a cotransmitter. Proctolin and neural stimulation produce delayed and sustained contractile effects without muscle depolarization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adams, M E -- O'Shea, M -- NS-16298/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 15;221(4607):286-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6134339" target="_blank"〉PubMed〈/a〉

    Burst discharge in mammalian neuroendocrine cells involves an intrinsic regenerative mechanism (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-09-09
    Beschreibung: Intracellular recordings from mammalian neuroendocrine cells showed that steady, injected currents can modify and block periodic spike bursts previously associated with increased neurohormone release. Spike afterpotentials could sum to form plateau potentials, which generated bursts and did not depend on axonal conduction or chemical synapses. Therefore, bursting involves a spike-dependent, positive-feedback mechanism endogenous to single neuroendocrine cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andrew, R D -- Dudek, F E -- NS 16877/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1983 Sep 9;221(4615):1050-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6879204" target="_blank"〉PubMed〈/a〉

    Primary murine bone marrow cultures support continuous growth of infectious human trypanosomes (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-04-22
    Beschreibung: The human parasite Trypanosoma brucei gambiense grew continuously at 37 degrees C in primary cultures of murine bone marrow. Cultured parasites remained virulent for mice. Rapid parasite growth coincided with the appearance of adherent adipocyte-epitheloid cell aggregates that also promoted hematopoiesis. This culture system should permit studies of host cell control of trypanosome proliferation, pathogenic effects of trypanosomes on blood cell development, and the relative trypanocidal and marrow suppressive activities of drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Balber, A E -- CA 14049/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 22;220(4595):421-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836284" target="_blank"〉PubMed〈/a〉

    Morphological basis of long-term habituation and sensitization in Aplysia (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-04-01
    Beschreibung: The morphological basis of the persistent synaptic plasticity that underlies long-term habituation and sensitization of the gill withdrawal reflex in Aplysia californica was explored by examining the fine structure of sensory neuron presynaptic terminals (the critical site of plasticity for the short-term forms of both types of learning) in control animals and in animals whose behavior had been modified by training. The number, size, and vesicle complement of sensory neuron active zones were larger in animals showing long-term sensitization than in control animals and smaller in animals showing long-term habituation. These changes are likely to represent an anatomical substrate for the memory consolidation of these tasks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bailey, C H -- Chen, M -- GM23540/GM/NIGMS NIH HHS/ -- MH37134-01/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 1;220(4592):91-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828885" target="_blank"〉PubMed〈/a〉

    Natural Distribution of the Ixodes dammini spirochete (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-04-15
    Beschreibung: Spirochetes believed to be the cause of Lyme disease were isolated from white-footed mice and white-tailed deer, the preferred natural hosts of Ixodes dammini, the tick vector. Evidence suggests that deer act as a reservoir of the disease and provide an overwintering mechanism for both spirochetes and adult ticks. Some tick larvae may acquire the spirochete by transovarial passage and the nymphal stage may transmit the disease to humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bosler, E M -- Coleman, J L -- Benach, J L -- Massey, D A -- Hanrahan, J P -- Burgdorfer, W -- Barbour, A G -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):321-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836274" target="_blank"〉PubMed〈/a〉

    Regulation of carcinogen metabolism in the rat ovary by the estrous cycle and gonadotropin (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-03-25
    Beschreibung: The activity of 7,12-dimethylbenz[a]anthracene hydroxylase in the rat ovary is several times higher in the proestrous phase of the estrous cycle than in the estrous and metestrous plus diestrous phases. Administration of gonadotropin leads to a similar increase in the capacity of the ovary to metabolize xenobiotics. This variation in the activity of 7,12-dimethylbenz[a]anthracene hydroxylase during the estrous cycle may be related to the marked changes in the incidence of ovarian cancer during menopause and in women taking contraceptive pills.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bengtsson, M -- Rydstrom, J -- New York, N.Y. -- Science. 1983 Mar 25;219(4591):1437-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6681915" target="_blank"〉PubMed〈/a〉
