    Description: The gp120 envelope glycoprotein of the human immunodeficiency virus (HIV), which is expressed on the surface of many HIV-infected cells, binds to the cell surface molecule CD4. Soluble derivatives of recombinant CD4 (rCD4) that bind gp120 with high affinity are attractive vehicles for targeting a cytotoxic reagent to HIV-infected cells. Soluble rCD4 was conjugated to the active subunit of the toxin ricin. This conjugate killed HIV-infected H9 cells but was 1/1000 as toxic to uninfected H9 cells (which do not express gp120) and was not toxic to Daudi cells (which express major histocompatibility class II antigens, the putative natural ligand for cell surface CD4). Specific killing of infected cells can be blocked by rgp120, rCD4, or a monoclonal antibody to the gp120 binding site on CD4.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Till, M A -- Ghetie, V -- Gregory, T -- Patzer, E J -- Porter, J P -- Uhr, J W -- Capon, D J -- Vitetta, E S -- CA-09082/CA/NCI NIH HHS/ -- CA-28149/CA/NCI NIH HHS/ -- CA-41081/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Nov 25;242(4882):1166-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Texas Southwestern Medical Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2847316" target="_blank"〉PubMed〈/a〉

    Description: Monkeys in which nerves innervating the flexor muscles of the forearm and hand (the ulnar or the median nerve) had been surgically cross-united with the nerve innervating the extensor muscles (the radial nerve), and vice versa, showed excellent (ulnar-radial crosses) to moderate (median-radial crosses) control of movement performance after regeneration. Antagonistic movement responses were seen occasionally, but these were corrected almost immediately. Stimulation of the crossed nerves showed that they had innervated the antagonistic muscle groups. The results reveal the capacity of the primate central nervous system to adapt to gross disturbances imposed on the execution of movements by changes in peripheral innervation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brinkman, C -- Porter, R -- Norman, J -- New York, N.Y. -- Science. 1983 Apr 22;220(4595):438-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836289" target="_blank"〉PubMed〈/a〉

    Description: The effects of marginal malnourishment , infections, and environmental chemicals on growth and reproductive success in Swiss-Webster white mice and wild deer mice were studied with fractional factorial designs. Interaction effects were discovered. For example, malnourished mice were more sensitive to virus exposure and environmental chemicals (a plant growth regulator or polychlorinated biphenyls). Since several commercial plant growth regulators also appear to suppress the immune system, these results cast doubt on the adequacy of current toxicity testing procedures in which factors are studied individually and not in combination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Porter, W P -- Hinsdill, R -- Fairbrother, A -- Olson, L J -- Jaeger, J -- Yuill, T -- Bisgaard, S -- Hunter, W G -- Nolan, K -- 5-T32-ES07015/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1984 Jun 1;224(4652):1014-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6426058" target="_blank"〉PubMed〈/a〉
