The Pl(A2) Polymorphism Of Integrin Beta(3) Enhances Outside-In Signaling And Adhesive Functions., K Vinod Vijayan, Pascal J. Goldschmidt-Clermont, Christine Roos, Paul F. Bray

Cardeza Foundation for Hematologic Research

Genetic factors are believed to influence the development of arterial thromboses. Because integrin alpha(IIb)beta(3) plays a crucial role in thrombus formation, we analyzed receptor adhesive properties using Chinese hamster ovary and human kidney embryonal 293 cells overexpressing the Pl(A1) or Pl(A2) polymorphic forms of alpha(IIb)beta(3). Soluble fibrinogen binding was no different between Pl(A1) and Pl(A2) cells, either in a resting state or when alpha(IIb)beta(3) was activated with anti-LIBS6. Pl(A1) and Pl(A2) cells bound equivalently to immobilized fibronectin. In contrast, significantly more Pl(A2) cells bound to immobilized fibrinogen in an alpha(IIb)beta(3)-dependent manner than did Pl(A1) cells. Disruption of the actin cytoskeleton …

The Optimal Fontan Connection: A Growing Extracardiac Lateral Tunnel With Pedicled Pericardium., S R. Gundry, A J. Razzouk, M J. Del Rio, Girish S. Shirali, L L. Bailey

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: The concept of a lateral tunnel for the Fontan operation is now widely accepted. Most lateral tunnels are constructed intraatrially with the use of aortic crossclamping. Construction of extracardiac lateral tunnels with the use of homografts or other nonviable tubes eliminates aortic crossclamping but lacks growth potential in length or width. The native pericardium, which is "sealed" posteriorly along the pulmonary artery, atrium, and inferior vena cava, could be turned down onto the right atrium to form a viable extracardiac lateral tunnel.

METHODS: We designed and successfully constructed extracardiac lateral tunnels using viable autologous pericardium, pedicled on its lateral …

Extraskeletal Mesenchymal Chondrosarcoma Of The Rectus Sheath., D B Johnson, W Breidahl, J S Newman, K Devaney, Alan M. Yahanda Md, Facs

PCI Publications and Projects

Mesenchymal chondrosarcomas (MSCs) are a rare form of chondrosarcoma which usually arise in bone. Extraskeletal chondrosarcomas constitute a minority (14-25%) of MSCs. We describe the imaging features of an extraskeletal mesenchymal chondrosarcoma that arose from the rectus abdominus muscle.

F(C)Gammari-Targeted Fusion Proteins Result In Efficient Presentation By Human Monocytes Of Antigenic And Antagonist T Cell Epitopes, Chunlei Liu, Joel Goldstein, Robert F. Graziano, Jia He, Jeremiah K. O'Shea, Yashwant Deo, Paul M. Guyre

Dartmouth Scholarship

A major challenge for using native or modified T cell epitopes to induce or suppress immunity relates to poor localization of peptides to antigen presenting cells (APCs) in vivo. In this study, we demonstrate enhanced presentation of antigenic and antagonistic peptides by targeting them to the type I Fc receptor for IgG (F(c)gammaRI, CD64) on human monocytes. A Th epitope of tetanus toxoid, TT830, and the antagonistic peptide for TT830, TT833S, were genetically grafted into the constant region of the heavy chain of the humanized anti-CD64 mAb 22 and expressed as monovalent fusion proteins, Fab22-TT830 and Fab22-TT833S. These CD64-targeted peptides …

Glanzmann Thrombasthenia. Cooperation Between Sequence Variants In Cis During Splice Site Selection., Ying Jin, Harry C. Dietz, Robert A. Montgomery, William R. Bell, Iain Mcintosh, Barry Coller, Paul F. Bray

Cardeza Foundation for Hematologic Research

Glanzmann thrombasthenia (GT), an autosomal recessive bleeding disorder, results from abnormalities in the platelet fibrinogen receptor, GP(IIb)-IIIa (integrin alpha(IIb)beta3). A patient with GT was identified as homozygous for a G-->A mutation 6 bp upstream of the GP(IIIa) exon 9 splice donor site. Patient platelet GP(IIIa) transcripts lacked exon 9 despite normal DNA sequence in all of the cis-acting sequences known to regulate splice site selection. In vitro analysis of transcripts generated from mini-gene constructs demonstrated that exon skipping occurred only when the G-->A mutation was cis to a polymorphism 116 bp upstream, providing precedence that two sequence variations …

Perception And Control Of Locomotion, John M. Flach

Psychology Faculty Publications

Over the past four years we have been studying problems of control and coordination with funds from AFOSR. Work over the first three years has been reviewed in the final report for the original AFOSR award (Flach, 1996). This report reviews work for the last year of the ASSERT grant. This work has focused on perception and control of low altitude flight. Experimental work from two synthetic task environments is described in this report. The first environment involved descent to low altitude. The key independent variables were speed of forward motion and optical texture (dot, grid, splay, depression). Results showed …

Pancreatic Expression Of Interleukin-4 Abrogates Insulitis And Autoimmune Diabetes In Nonobese Diabetic (Nod) Mice., Regula Mueller, Troy Krahl, Nora Sarvetnick

Journal Articles: Regenerative Medicine

Diabetes in nonobese diabetic (NOD) mice is a T cell-dependent autoimmune disease. The destructive activities of autoreactive T cells have been shown to be tightly regulated by effector molecules. In particular, T helper (Th) 1 cytokines have been linked to diabetes pathogenesis, whereas Th2 cytokines and the cells that release them have been postulated to be protective from disease. To test this hypothesis, we generated transgenic NOD mice that express interleukin (IL) 4 in their pancreatic beta cells under the control of the human insulin promoter. We found that transgenic NOD-IL-4 mice, both females and males, were completely protected from …

Efficient Vasoactive Intestinal Polypeptide Hydrolyzing Autoantibody Light Chains Selected By Phage Display, Sonia Tyutyulkova, Qing-Sheng Gao, Austin Thompson, Stephen I. Rennard, Sudhir Paul

Journal Articles: Pulmonary & Critical Care Med

An immunoglobulin light chain (L chain) library derived from the peripheral blood lymphocytes of a patient with asthma was cloned into a phagemid vector. Phage particles displaying L chains capable of binding vasoactive intestinal polypeptide (VIP) were isolated by affinity chromatography. Two VIP binding L chains were expressed in Escherichia coli in soluble form and purified to electrophoretic homogeneity by metal chelating and protein L affinity chromatography. Both L chains catalyzed the hydrolysis of [tyr10-125I]VIP substrate. The catalytic activity eluted at the molecular mass of the monomer form of the L chain (28 kDa) from a gel filtration column. The …

A Novel Iron-Regulated Metal Transporter From Plants Identified By Functional Expression In Yeast., David Eide, Margaret Broderius, Jeanette Fett, Mary Lou Guerinot

Dartmouth Scholarship

Iron is an essential nutrient for virtually all organisms. The IRT1 (iron-regulated transporter) gene of the plant Arabidopsis thaliana, encoding a probable Fe(II) transporter, was cloned by functional expression in a yeast strain defective for iron uptake. Yeast expressing IRT1 possess a novel Fe(II) uptake activity that is strongly inhibited by Cd. IRT1 is predicted to be an integral membrane protein with a metal-binding domain. Data base comparisons and Southern blot analysis indicated that IRT1 is a member of a gene family in Arabidopsis. Related sequences were also found in the genomes of rice, yeast, nematodes, and humans. In Arabidopsis, …

Myasthenia Gravis-Like Syndrome Induced By Expression Of Interferon Gamma In The Neuromuscular Junction., Danling Gu, Lise Wogensen, Nigel A. Calcutt, Chunyao Xia, Simin Zhu, John P. Merlie, Howard S. Fox, Jon Lindstrom, Henry C. Powell, Nora Sarvetnick

Journal Articles: Regenerative Medicine

Abnormal humoral responses toward motor end plate constituents in muscle induce myasthenia gravis (MG). To study the etiology of this disease, and whether it could be induced by host defense molecules, we examined the consequences of interferon (IFN) gamma production within the neuromuscular junction of transgenic mice. The transgenic mice exhibited gradually increasing muscular weakness, flaccid paralysis, and functional disruption of the neuromuscular junction that was reversed after administration of an inhibitor of acetylcholinesterase, features which are strikingly similar to human MG. Furthermore, histological examination revealed infiltration of mononuclear cells and autoantibody deposition at motor end plates. Immunoprecipitation analysis indicated …
