  1. 1. T-cell responses to Helicobacter pylori in humans and a possible role of regulatory T cells

    Författare :Anna Lundgren; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; T cells; regulatory T cells; dendritic cells; T-cell recruitment;

    Sammanfattning : Helicobacter pylori colonize the stomach and areas of gastric metaplasia in the duodenum. The bacteria induce both local and systemic immune responses, but despite this, the infection normally persists for life and causes chronic gastritis in all infected subjects and peptic ulcers or gastric cancer in 10-20% of infected individuals.

  3. 2. Human embryonic stem cells for bone engineering applications

    Författare :Giuseppe Maria de Peppo; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human skeleton; bone; bone defects; bone regeneration; regenerative medicine; tissue engineering; biomaterials; scaffold; biocoral; titanium; osseointegration bioreactor; human stem cells; embryonic stem cells; mesenchymal stem cells; embryonic-derived progenitors; osteogenic differentiation; mineralization; immune response; in vitro; in vivo;

    Sammanfattning : The human skeleton represents the supporting structure of the organism and accounts for about 20 percent of the total body mass. Despite its intrinsic capacity to regenerate and self-repair, this ability is limited and repair therapies are needed in a large number of clinical cases. LÄS MER

  4. 3. Roles of PDGF for Neural Stem Cells

    Författare :Mia Enarsson; Karin Nilsson; Bengt Westermark; Peter Eriksson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; CNS; stem cells; neuron; PDGF; proliferation; differentiation; ERK; microarray; transgenic mouse; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : Stem cells are endowed with unique qualities: they can both self-renew and give rise to new mature cell types. Central nervous system (CNS) stem cells can give rise to neurons and glia. LÄS MER

  5. 4. Mechanisms in Tendon Healing : Pain, Biomarkers and the Role of Mast Cells

    Författare :Abdul Alim; Magnus Peterson; Gunnar Pejler; Per Kristiansson; Paul W. Ackermann; Gustav Andersson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tendon Healing; Pain; Biomarkers; Mast Cells; Inflammation; Microdialysis; Neurotransmitters; Glutamate Receptors; Procollagen; Transcriptional factors; Biology with specialization in Molecular Immunology; Biologi med inriktning mot molekylär immunologi; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Neuroscience; Neurovetenskap;

    Sammanfattning : Tendon injuries and tendinopathy are common disorders, but the underlying mechanisms are not well understood. The overall aim of this thesis was to better understand the mechanisms underlying tendon healing, pain, and inflammation. LÄS MER

  7. 5. T cells and chemokines in rheumatoid arthritis

    Författare :Jonathan Aldridge; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; CD4 T cells; chemokines; disease activity; biomarker; CTLA-4Ig;

    Sammanfattning : In this thesis, we investigated if circulating proportions of specific CD4+ T cell subsets and blood chemokine levels were associated with disease activity and/or could predict remission in patients with early rheumatoid arthritis (eRA). We also compared the effect of different biological treatments on both T cell subset proportions and chemokine levels. LÄS MER
