Description:
Leukocyte adhesion deficiency (LAD) is an inherited disorder of leukocyte function caused by derangements in CD18 expression. The genetic and functional abnormalities in a lymphocyte cell line from a patient with LAD have been corrected by retrovirus-mediated transduction of a functional CD18 gene. Lymphocytes from patients with LAD were exposed to CD18-expressing retrovirus and enriched for cells that express CD11a and CD18 (LFA-1) on the cell surface. Molecular and functional analyses of these cells revealed (i) one copy of proviral sequence per cell, (ii) viral-directed CD18 RNA that exceeded normal endogenous levels, (iii) normal quantities of CD11a and CD18 protein on the cell surface, and (iv) reconstitution of LFA-1-dependent adhesive function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, J M -- Ping, A J -- Krauss, J C -- Mayo-Bond, L -- Rogers, C E -- Anderson, D C -- Todd, R F -- R01 AI19031/AI/NIAID NIH HHS/ -- R01 AI23521/AI/NIAID NIH HHS/ -- R01 CA39064/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1990 Jun 15;248(4961):1413-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Internal Medicine, Ann Arbor, MI.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1972597" target="_blank"〉PubMed〈/a〉
