  1. 1. Towards Gene Therapy of Osteopetrosis

    University dissertation from Department of Molecular Medicine and Gene Therapy, Lund University

    Author : Maria Askmyr; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Haematology; oc oc mice; osteoclast; hematopoietic stem cells; Hematologi; extracellulära vätskor;

    Abstract : The goal in this thesis is development of gene therapy for malignant infantile osteopetrosis (IMO), a rare but severe genetic bone disease. The concept of osteopetrosis implies dysfunction or lack of osteoclasts, the bone resorbing cells in our body, resulting in failure of normal bone breakdown. READ MORE

  2. 2. On the role of the retinoblastoma tumor suppressor gene in hematopoietic differentiation

    University dissertation from Gösta Bergh, Kävlingev 1, S-222 40 Lund, Sweden

    Author : Gösta Bergh; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antisense; leukemia; cell cycle; differentiation; hematopoiesis; p16; p53; tumor suppressor genes; RB; oligonucleotides; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

    Abstract : The aim of this study was to investigate the role of some tumor suppressor gene products (with emphasis on the retinoblastoma suppressor gene product) in the regulation of differentiation and proliferation in leukemic and normal hematopoietic cells. For this purpose, the expression of the tumor suppressor genes RB, p53 and p16 were artificially altered. READ MORE

  3. 3. Processing of TNF-receptors to soluble receptor forms in myeloid cells

    University dissertation from Research Department 2, University Hospital, S-221 85 LUND, SWEDEN

    Author : Flemming Björnberg; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammation cytokine TNF receptor; extracellular fluids; Haematology; Hematologi; extracellulära vätskor;

    Abstract : TNF (Tumor Necrosis Factor) is a pro-inflammatory cytokine which binds to two cell surface receptors, TNF-R55 and TNF-R75. The receptors undergo proteolytic cleavage and release a fragment (soluble TNF-receptors or TNF-Binding Protein), TNF-R55-BP and TNF-R75-BP. Soluble TNF-receptors are able to bind and inactivate TNF.

  4. 4. Hox transcription factors in hematopoiesis

    University dissertation from Dept. Mol. Med. and Gene Therapy, BMC A12, 221 84, Lund

    Author : Jon Mar Björnsson; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Hematologi; extracellulära vätskor; Haematology; hematopoies; tet; Hox; cre lox;

    Abstract : Hematopoiesis is a lifelong, dynamic process in which a small number of pluripotent hematopoietic stem cells (HSC) residing in the bone marrow (BM) give rise to billions of mature blood cells of both myeloid and lymphoid origin each day. This enormous capacity of HSC has been utilized in BM transplantations for 4 decades and is also very important for future gene therapy. READ MORE

  5. 5. Maintenance and Commitment of Hematopoietic Progenitors: Role of flt3, c-kit and c-mpl

    University dissertation from Dept. Mol. Med. and Gene Therapy, BMC A12, 221 84, Lund

    Author : Ole Johan Borge; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; KL; hematopoiesis; FL; cytokines; B-cells; commitment; flt3; differentiation; Haematology; IL-7; c-kit; progenitors; Hematologi; stem cells; thrombopoietin; viability; extracellular fluids; extracellulära vätskor;

    Abstract : The need for red blood cells to transport oxygen and CO2, blood platelets to stop bleedings, and neutrophils, macrophages, B- and T-cells for host defense, is a prerequisite for life. These mature blood cells have a limited life span and are thus constantly replenished by an enormous cell production (estimated to 1012 cells per day) which primarily takes place in the bone marrow (BM).
