    Description: Severe combined immunodeficient (SCID) mice reconstituted with human peripheral blood leukocytes (hu-PBL-SCID mice) have inducible human immune function and may be useful as a small animal model for acquired immunodeficiency syndrome (AIDS) research. Hu-PBL-SCID mice infected with human immunodeficiency virus-1 (HIV-1) contained virus that was recoverable by culture from the peritoneal cavity, spleen, peripheral blood, and lymph nodes for up to 16 weeks after infection; viral sequences were also detected by in situ hybridization and by amplification with the polymerase chain reaction (PCR). Mice could be infected with multiple strains of HIV-1, including LAV-1/Bru, IIIB, MN, SF2, and SF13. HIV-1 infection affected the concentration of human immunoglobulin and the number of CD4+ T cells in the mice. These results support the use of the hu-PBL-SCID mouse for studies of the pathogenesis and treatment of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mosier, D E -- Gulizia, R J -- Baird, S M -- Wilson, D B -- Spector, D H -- Spector, S A -- AI-27703/AI/NIAID NIH HHS/ -- AI-29182/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1991 Feb 15;251(4995):791-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Immunology, Medical Biology Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1990441" target="_blank"〉PubMed〈/a〉

    Description: Three spatially distant surface loops were found to mediate the interaction of the coagulation protein factor X with the leukocyte integrin Mac-1. This interacting region, which by computational modeling defines a three-dimensional macromotif in the catalytic domain, was also recognized by glycoprotein C (gC), a factor X receptor expressed on herpes simplex virus (HSV)-infected endothelial cells. Peptidyl mimicry of each loop inhibited factor X binding to Mac-1 and gC, blocked monocyte generation of thrombin, and prevented monocyte adhesion to HSV-infected endothelium. These data link the ligand recognition of Mac-1 to established mechanisms of receptor-mediated vascular injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altieri, D C -- Etingin, O R -- Fair, D S -- Brunck, T K -- Geltosky, J E -- Hajjar, D P -- Edgington, T S -- HL 46408/HL/NHLBI NIH HHS/ -- P01 HL 16411/HL/NHLBI NIH HHS/ -- R01 HL 43773/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Nov 22;254(5035):1200-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1957171" target="_blank"〉PubMed〈/a〉

    Description: Neurotransmitter receptors are generally clustered in the postsynaptic membrane. The mechanism of clustering was analyzed with fibroblast cell lines that were stably transfected with the four subunits for fetal (alpha, beta, gamma, delta) or adult (alpha, beta, epsilon, delta) type mouse muscle nicotinic acetylcholine receptors (AChRs). Immunofluorescent staining indicated that AChRs were dispersed on the surface of these cells. When transiently transfected with an expression construct encoding a 43-kilodalton protein that is normally concentrated under the postsynaptic membrane, AChRs expressed in these cells became aggregated in large cell-surface clusters, colocalized with the 43-kilodalton protein. This suggests that 43-kilodalton protein can induce AChR clustering and that cluster induction involves direct contact between AChR and 43-kilodalton protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phillips, W D -- Kopta, C -- Blount, P -- Gardner, P D -- Steinbach, J H -- Merlie, J P -- R01 NS022356/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Feb 1;251(4993):568-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1703661" target="_blank"〉PubMed〈/a〉

    Description: An expression cloning strategy was devised to isolate the keratinocyte growth factor (KGF) receptor complementary DNA. NIH/3T3 fibroblasts, which secrete this epithelial cell-specific mitogen, were transfected with a keratinocyte expression complementary DNA library. Among several transformed foci identified, one demonstrated the acquisition of specific high-affinity KGF binding sites. The pattern of binding competition by related fibroblast growth factors (FGFs) indicated that this receptor had high affinity for acidic FGF as well as KGF. The rescued 4.2-kilobase complementary DNA was shown to encode a predicted membrane-spanning tyrosine kinase related to but distinct from the basic FGF receptor. This expression cloning approach may be generally applicable to the isolation of genes that constitute limiting steps in mitogenic signaling pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miki, T -- Fleming, T P -- Bottaro, D P -- Rubin, J S -- Ron, D -- Aaronson, S A -- New York, N.Y. -- Science. 1991 Jan 4;251(4989):72-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cellular and Molecular Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1846048" target="_blank"〉PubMed〈/a〉

    Description: The three-dimensional structure of an active, disulfide cross-linked dimer of the ligand-binding domain of the Salmonella typhimurium aspartate receptor and that of an aspartate complex have been determined by x-ray crystallographic methods at 2.4 and 2.0 angstrom (A) resolution, respectively. A single subunit is a four-alpha-helix bundle with two long amino-terminal and carboxyl-terminal helices and two shorter helices that form a cylinder 20 A in diameter and more than 70 A long. The two subunits in the disulfide-bonded dimer are related by a crystallographic twofold axis in the apo structure, but by a noncrystallographic twofold axis in the aspartate complex structure. The latter structure reveals that the ligand binding site is located more than 60 A from the presumed membrane surface and is at the interface of the two subunits. Aspartate binds between two alpha helices from one subunit and one alpha helix from the other in a highly charged pocket formed by three arginines. The comparison of the apo and aspartate complex structures shows only small structural changes in the individual subunits, except for one loop region that is disordered, but the subunits appear to change orientation relative to each other. The structures of the two forms of this protein provide a step toward understanding the mechanisms of transmembrane signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Milburn, M V -- Prive, G G -- Milligan, D L -- Scott, W G -- Yeh, J -- Jancarik, J -- Koshland, D E Jr -- Kim, S H -- AI 30725/AI/NIAID NIH HHS/ -- DK09765/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 29;254(5036):1342-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1660187" target="_blank"〉PubMed〈/a〉

    Description: Humoral immunity is important for protection against viral infection and neutralization of extracellular virus, but clearance of virus from infected tissues is thought to be mediated solely by cellular immunity. However, in a SCID mouse model of persistent alphavirus encephalomyelitis, adoptive transfer of hyperimmune serum resulted in clearance of infectious virus and viral RNA from the nervous system, whereas adoptive transfer of sensitized T lymphocytes had no effect on viral replication. Three monoclonal antibodies to two different epitopes on the E2 envelope glycoprotein mediated viral clearance. Treatment of alphavirus-infected primary cultured rat neurons with these monoclonal antibodies to E2 resulted in decreased viral protein synthesis, followed by gradual termination of mature infectious virion production. Thus, antibody can mediate clearance of alphavirus infection from neurons by restricting viral gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levine, B -- Hardwick, J M -- Trapp, B D -- Crawford, T O -- Bollinger, R C -- Griffin, D E -- NS29234/NS/NINDS NIH HHS/ -- T32-NS-07000/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 8;254(5033):856-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1658936" target="_blank"〉PubMed〈/a〉

    Description: The trk proto-oncogene encodes a 140-kilodalton, membrane-spanning protein tyrosine kinase (p140prototrk) that is expressed only in neural tissues. Nerve growth factor (NGF) stimulates phosphorylation of p140prototrk in neural cell lines and in embryonic dorsal root ganglia. Affinity cross-linking and equilibrium binding experiments with 125I-labeled NGF indicate that p140prototrk binds NGF specifically in cultured cells with a dissociation constant of 10(-9) molar. The identification of p140prototrk as an NGF receptor indicates that this protein participates in the primary signal transduction mechanism of NGF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaplan, D R -- Hempstead, B L -- Martin-Zanca, D -- Chao, M V -- Parada, L F -- N01-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Apr 26;252(5005):554-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Eukaryotic Signal Transduction Group, National Cancer Institute-Frederick Cancer Research and Development Center, MD 21702.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1850549" target="_blank"〉PubMed〈/a〉

    Description: The 2.05 angstrom (A) resolution crystal structure of a dodecasaccharide-Fab complex revealed an unusual carbohydrate recognition site, defined by aromatic amino acids and a structured water molecule, rather than the carboxylic acid and amide side chains and a structured water molecule, rather than the carboxylic acid and amide side chains that are features of transport and other carbohydrate binding proteins. A trisaccharide epitope of a branched bacterial lipopolysaccharide fills this hydrophobic pocket (8 A deep by 7 A wide) in an entropy-assisted association (association constant = 2.05 x 10(5) liters per mole, enthalpy = -20.5 +/- 1.7 kilojoules per mole, and temperature times entropy = +10.0 +/- 2.9 kilojoules per mole). The requirement for the complementarity of van der Waals surfaces and the requirements of saccharide-saccharide and protein-saccharide hydrogen-bonding networks determine the antigen conformation adopted in the bound state.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cygler, M -- Rose, D R -- Bundle, D R -- New York, N.Y. -- Science. 1991 Jul 26;253(5018):442-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biotechnology Research Institute, National Research Council of Canada, Montreal, Quebec.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1713710" target="_blank"〉PubMed〈/a〉

    Description: The Rel-associated protein pp40 is functionally related to I kappa B, an inhibitor of the transcription factor NF-kappa B. Purified pp40 inhibits the DNA binding activity of the NF-kappa B protein complex (p50:p65 heterodimers), p50:c-Rel heteromers, and c-Rel homodimers. The sequence of the complementary DNA encoding pp40 revealed similarity to the gene encoding MAD-3, a protein with mammalian I kappa B-like activity. Protein sequencing of I kappa B purified from rabbit lung confirmed that MAD-3 encodes a protein similar to I kappa B. The sequence similarity between MAD-3 and pp40 includes a casein kinase II and consensus tyrosine phosphorylation site, as well as five repeats of a sequence found in the human erythrocyte protein ankyrin. These results suggest that rel-related transcription factors, which are capable of cytosolic to nuclear translocation, may be held in the cytosol by interaction with related cytoplasmic anchor molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, N -- Ghosh, S -- Simmons, D L -- Tempst, P -- Liou, H C -- Baltimore, D -- Bose, H R Jr -- CA09583/CA/NCI NIH HHS/ -- CA2616/CA/NCI NIH HHS/ -- CA33192/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Sep 13;253(5025):1268-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Texas, Austin 78712.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1891714" target="_blank"〉PubMed〈/a〉

    Description: Microbial enzyme systems may be used in the biodegradation of persistent environmental pollutants. The three polypeptide components of one such system, the 4-chlorobenzoate dehalogenase system, have been isolated, and the chemical steps of the 4-hydroxybenzoate-forming reaction that they catalyze have been identified. The genes contained within a 4.5-kilobase Pseudomonas sp. strain CBS3 chromosomal DNA fragment that encode dehalogenase activity were selectively expressed in transformed Escherichia coli. Oligonucleotide sequencing revealed a stretch of homology between the 57-kilodalton (kD) polypeptide and several magnesium adenosine triphosphate (MgATP)-cleaving enzymes that allowed MgATP and coenzyme A (CoA) to be identified as the dehalogenase cosubstrate and cofactor, respectively. The dehalogenase activity arises from two components, a 4-chlorobenzoate:CoA ligase-dehalogenase (an alpha beta dimer of the 57- and 30-kD polypeptides) and a thioesterase (the 16-kD polypeptide).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scholten, J D -- Chang, K H -- Babbitt, P C -- Charest, H -- Sylvestre, M -- Dunaway-Mariano, D -- GM 28688/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 12;253(5016):182-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of Maryland, College Park 20742.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1853203" target="_blank"〉PubMed〈/a〉
