    Description: Pertussis toxin is produced by the causative agent of whooping cough, Bordetella pertussis, and is an adenosine diphosphate (ADP)-ribosyltransferase capable of covalently modifying and thereby inactivating many eukaryotic G proteins involved in cellular metabolism. The toxin is a principal determinant of virulence in whooping cough and is a primary candidate for an acellular pertussis vaccine, yet it is unclear whether the ADP-ribosyltransferase activity is required for both pathogenic and immunoprotective activities. A B. pertussis strain that produced an assembled pertussis holotoxin with only 1 percent of the ADP-ribosyltransferase activity of the native toxin was constructed and was found to be deficient in pathogenic activities associated with B. pertussis including induction of leukocytosis, potentiation of anaphylaxis, and stimulation of histamine sensitivity. Moreover, this mutant strain failed to function as an adjuvant and was less effective in protecting mice from intracerebral challenge infection. These data suggest that the ADP-ribosyltransferase activity is necessary for both pathogenicity and optimum immunoprotection. These findings bear directly on the design of a nontoxic pertussis vaccine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Black, W J -- Munoz, J J -- Peacock, M G -- Schad, P A -- Cowell, J L -- Burchall, J J -- Lim, M -- Kent, A -- Steinman, L -- Falkow, S -- AI-22462/AI/NIAID NIH HHS/ -- AI-23945/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1988 Apr 29;240(4852):656-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Microbiology, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2896387" target="_blank"〉PubMed〈/a〉

    Description: Interleukin-1 alpha and -1 beta (IL-1 alpha and IL-1 beta) are cytokines that participate in the regulation of immune responses, inflammatory reactions, and hematopoiesis. A direct expression strategy was used to clone the receptor for IL-1 from mouse T cells. The product of the cloned complementary DNA binds both IL-1 alpha and IL-1 beta in a manner indistinguishable from that of the native T cell IL-1 receptor. The extracellular, IL-1 binding portion of the receptor is 319 amino acids in length and is composed of three immunoglobulin-like domains. The cytoplasmic portion of the receptor is 217 amino acids long.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sims, J E -- March, C J -- Cosman, D -- Widmer, M B -- MacDonald, H R -- McMahan, C J -- Grubin, C E -- Wignall, J M -- Jackson, J L -- Call, S M -- New York, N.Y. -- Science. 1988 Jul 29;241(4865):585-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immunex Corporation, Seattle, WA 98101.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2969618" target="_blank"〉PubMed〈/a〉

    Description: Alpha particles are energetic short-range ions whose higher linear energy transfer produces extreme cytotoxicity. An alpha-particle-emitting radioimmunoconjugate consisting of a bismuth-212-labeled monoclonal immunoglobulin M specific for the murine T cell/neuroectodermal surface antigen Thy 1.2 was prepared. Analysis in vitro showed that the radioimmunoconjugate was selectively cytotoxic to a Thy 1.2+ EL-4 murine tumor cell line. Approximately three bismuth-212-labeled immunoconjugates per target cell reduced the uptake of [3H]thymidine by the EL-4 target cells to background levels. Mice inoculated intraperitoneally with EL-4 cells were cured of their ascites after intraperitoneal injection of 150 microcuries of the antigen-specific radioimmunoconjugate, suggesting a possible role for such conjugates in intracavitary cancer therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Macklis, R M -- Kinsey, B M -- Kassis, A I -- Ferrara, J L -- Atcher, R W -- Hines, J J -- Coleman, C N -- Adelstein, S J -- Burakoff, S J -- 5 PO1-CA39542-03/CA/NCI NIH HHS/ -- 5T32 CA 09536-01/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 May 20;240(4855):1024-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Joint Center for Radiation Therapy, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2897133" target="_blank"〉PubMed〈/a〉

    Description: Rat atrial natriuretic factor (ANF) is translated as a 152-amino acid precursor preproANF. PreproANF is converted to the 126-amino acid proANF, the storage form of ANF in the atria. ANF isolated from the blood is approximately 25 amino acids long. It is demonstrated here that rat cardiocytes in culture store and secrete proANF. Incubation of proANF with serum produced a smaller ANF peptide. PreproANF seems to be processed to proANF in the atria, and proANF appears to be released into the blood, where it is converted by a protease to a smaller peptide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bloch, K D -- Scott, J A -- Zisfein, J B -- Fallon, J T -- Margolies, M N -- Seidman, C E -- Matsueda, G R -- Homcy, C J -- Graham, R M -- Seidman, J G -- 1R23CA33570/CA/NCI NIH HHS/ -- HL07208/HL/NHLBI NIH HHS/ -- HL26215/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1985 Dec 6;230(4730):1168-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2933808" target="_blank"〉PubMed〈/a〉

    Description: Cachectin (tumor necrosis factor), a protein produced in large quantities by endotoxin-activated macrophages, has been implicated as an important mediator of the lethal effect of endotoxin. Recombinant human cachectin was infused into rats in an effort to determine whether cachectin, by itself, can elicit the derangements of host physiology caused by administration of endotoxin. When administered in quantities similar to those produced endogenously in response to endotoxin, cachectin causes hypotension, metabolic acidosis, hemoconcentration, and death within minutes to hours, as a result of respiratory arrest. Hyperglycemia and hyperkalemia were also observed after infusion. At necropsy, diffuse pulmonary inflammation and hemorrhage were apparent on gross and histopathologic examination, along with ischemic and hemorrhagic lesions of the gastrointestinal tract, and acute renal tubular necrosis. Thus, it appears that a single protein mediator (cachectin) is capable of inducing many of the deleterious effects of endotoxin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tracey, K J -- Beutler, B -- Lowry, S F -- Merryweather, J -- Wolpe, S -- Milsark, I W -- Hariri, R J -- Fahey, T J 3rd -- Zentella, A -- Albert, J D -- New York, N.Y. -- Science. 1986 Oct 24;234(4775):470-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3764421" target="_blank"〉PubMed〈/a〉

    Description: The clathrin light chains fall into two major classes, LCA and LCB. In an intact clathrin triskelion, one light chain, of either class, is bound to the proximal segment of a heavy chain leg. Analysis of rat brain and liver complementary DNA clones for LCA and LCB shows that the two light chain classes are closely related. There appear to be several members of each class having deletions of varying length aligned at the same position. A set of ten heptad elements, characteristic of alpha-helical coiled coils, is a striking feature of the central part of each derived amino acid sequence. These observations suggest a model in which the alpha-helical segment mediates binding to clathrin heavy chains and the amino- and carboxyl-terminal segments mediate interactions with other proteins. They also suggest an explanation for the observed tissue-dependent size variation for members of each class.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kirchhausen, T -- Scarmato, P -- Harrison, S C -- Monroe, J J -- Chow, E P -- Mattaliano, R J -- Ramachandran, K L -- Smart, J E -- Ahn, A H -- Brosius, J -- MH 38819/MH/NIMH NIH HHS/ -- R01 GM 36548-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Apr 17;236(4799):320-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3563513" target="_blank"〉PubMed〈/a〉

    Description: Growth cones are specialized structures that form the distal tips of growing axons. During both normal development of the nervous system and regeneration of injured nerves, growth cones are essential for elongation and guidance of growing axons. Developmental and regenerative axon growth is frequently accompanied by elevated synthesis of a protein designated GAP-43. GAP-43 has now been found to be a major component of growth-cone membranes in developing rat brains. Relative to total protein, GAP-43 is approximately 12 times as abundant in growth-cone membranes as in synaptic membranes from adult brains. Immunohistochemical localization of GAP-43 in frozen sections of developing brain indicates that the protein is specifically associated with neuropil areas containing growth cones and immature synaptic terminals. The results support the proposal that GAP-43 plays a role in axon growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Skene, J H -- Jacobson, R D -- Snipes, G J -- McGuire, C B -- Norden, J J -- Freeman, J A -- EY01117/EY/NEI NIH HHS/ -- EY03718/EY/NEI NIH HHS/ -- NS18103/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Aug 15;233(4765):783-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3738509" target="_blank"〉PubMed〈/a〉

    Description: Ozone and temperature profiles were measured in 50 balloon flights at McMurdo Station (78 deg S) during the spring of 1987. Compared to similar data obtained in 1986, stratospheric temperatures were lower and the spring time Antarctic ozone reduction was greater in magnitude, extended to higher altitude, and proceeded at a higher rate in 1987. Ozone partial pressures reached values as low as 3 nbar (as compared to about 10 nbar in 1986) in the 16- to 18-km region in early and late October, down from about 150 nbar in late August. These low values suggest essentially complete removal of ozone in this region. The upper boundary of the depletion region was observed to be 2-3 km higher than in 1986, extending to altitudes as high as 24 km in mid-September. When averaged over September, the ozone mixing ratio at 18 km decayed with a half-life of only 12.4 days, as compared to about 28 days in 1986. Adiabatic vertical motions over 1- to 2-km intervals between 12 and 20 km with consequent ozone reductions were observed in association with the formation of nacreous clouds, indicating these to be rare events on a local scale probably associated with mountain lee waves.

    Description: Global monthly mean charts for both hemispheres are given for four mid-season months, and for the pressure levels 30, 10, 1, and 0.1 mbar for temperature and 0.4 mbar for ozone. Charts of total ozone are provided separately. This set of charts shows clearly the very close coupling between the temperature and ozone distributions and demonstrates the influence of the large-scale planetary waves which give rise to very large longitudinal variations. The regular and interannual variability of temperature and ozone are discussed.
