1. 1. Studies on the Bcl-2 Family of Apoptosis Regulators in the Nervous System

   Författare :Susanne Hamnér; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Bcl-2; Bcl-w; Bad; Apoptosis; Nervous system; Cerebellar granule cells; Sympathetic neurons; Neurovetenskap; Neurology; Neurologi; Developmental Neurosciences; medicinsk utvecklings- och neurobiologi;

   Sammanfattning : Apoptosis is a type of cell death with a specific morphology and molecular program, which is essential for the development of the nervous system. However, inappropriate cell death has been implicated in several neurodegenerative diseases. LÄS MER

3. 2. In vitro Studies of β-cell Death and Survival. Modulation by Adenoviral Vectors and Bcl-2 Overexpression

   Författare :Andreea Roxana Barbu; Nils Welsh; Decio Eiziric; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; β-cell; cytokine; mitochondrial membrane potential; Bcl-2; Adenoviral vector; Adenovirus; IFN-α; Diabetes; Cellbiologi; Cell biology; Cellbiologi;

   Sammanfattning : Type 1 diabetes is a multifactorial disease resulting from the selective destruction of insulin-producing β-cells within the pancreatic islets of Langerhans. The mechanisms of β-cell death are not fully understood but cytokines are important mediators of this process. LÄS MER

4. 3. Insight into the mitochondrial apoptotic pathway : The interplay of the pro-apoptotic Bax protein with oxidized phospholipids and its counterplayer, the pro-survival Bcl-2 protein

   Författare :Marcus Wallgren; Gerhard Gröbner; Marco Colombini; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; apoptosis; Bax; Bcl-2; CD; cell-free protein synthesis; DSC; membrane; mitochondria; oxidized phospholipids; reconstitution; solid state NMR; biologisk kemi; biological chemistry;

   Sammanfattning : Apoptosis plays a crucial role in multicellular organisms by preserving tissue homeostasis and removing harmful cells. The anti-apoptotic B-cell CLL/lymphoma 2 (Bcl-2) and the pro-apoptotic Bcl-2-associated X protein (Bax) act as major regulators of the mitochondrial apoptotic pathway. LÄS MER

5. 4. Aspects of pathological apoptosis in the immature brain after hypoxia-ischemia

   Författare :Ulrika Hallin; Göteborgs universitet; []
   Nyckelord :neonatal; rat; brain; hypoxia-ischemia; necrosis; apoptosis; calpain; caspase; Bcl-2; Bax; mitochondria; calcineurin.;

   Sammanfattning : The cause of mechanisms underlying perinatal brain injury is not fully known, but it results in a wide variety of neurological impairments in the affected children. When injured, neurons of the newborn brain are prone to undergo programmed cell death, apoptosis, since this genetic program is normally activated in some cells during development of the nervous system, even in the perinatal period.

7. 5. Mechanisms of survival and maintenance of Hematopoietic Stem Cells and Multipotent Progenitor Cells

   Författare :Richard Karlsson; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; Hematologi; extracellular fluids; Haematology; hypoxia.; forkhead; Akt PKB; Bcl-2; apoptosis; Flt3; FL; c-kit; KL; cytokines; Hematopoiesis; progenitor;

   Sammanfattning : Hematopoietic stem cells and progenitor cells are maintained in the bone marrow microenvironment, where factors including soluble and membrane-bound cytokines influence the processes of self-renewal, proliferation and differentiation. Two nonreduntant cytokines with effects on hematopoiesis, Kit Ligand (KL) and Flt3 Ligand (FL), signal via related tyrosine kinase receptors, c-kit and Flt3. LÄS MER
