  1. 36. Apoptosis And Excitotoxicity In The Death of Cultured And Grafted Dopaminergic Neurones

    Författare :Gabriele Schierle; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ac-YVAD-cmk; MK-801; flunarizine; N-methyl-D-aspartate; voltage-dependent calcium channels; Bcl-2; caspase; excitotoxicity; apoptosis; tyrosine hydroxylase; dopamine; Parkinson s disease; intracerebral transplantation; Poly ADP-ribose polymerase; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Over the past two decades, grafting of embryonic nigral tissue has developed into a feasible therapeutic strategy for Parkinson's disease (PD). It has become apparent that the degree of restoration of dopaminergic neurotransmission by the transplanted cells is highly correlated to the symptomatic relief. LÄS MER

  3. 37. Regulation of Apoptosis in Hematopoietic Progenitor Cells: Involvement of Different Signaling Pathways

    Författare :Maria Kraft; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytokines; apoptosis; cell cycle; c-Kit; Flt3; Flt3-ITD; Akt; Bcl-2; FoxO3; mouse; hematopoiesis; progenitor;

    Sammanfattning : Proliferation, differentiation, and survival of hematopoietic stem cells and multipotent progenitor cells are regulated by cytokines and cell-cell interactions. Kit ligand (KL) and Flt3 ligand (FL) have pleiotropic effects, promotes survival, but are nonredundant. LÄS MER

  4. 38. On the Role of Polyamines in Apoptosis

    Författare :Cecilia Hegardt; Bröstcancer-genetik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SSAT; DENSPM; spermine; polyamines; mitochondrial membrane potential; cytochrome c; caspase; flow cytometry; Jurkat cells; mouse thymocytes; thymus in vivo; programmed cell death; Dexamethasone-induced apoptosis; Fas-induced apoptosis; AdoMetDC; Cytology; oncology; cancerology; Cytologi; onkologi; cancer; Clinical biology; Klinisk biologi; Animal physiology; Djurfysiologi;

    Sammanfattning : Apoptosis is a kind of death that is best described as cellular suicide and it is important for normal tissue homeostasis. The process can be induced by a number of different stimuli and the dying cell goes through a defined pathway terminating in typical biochemical and morphological alterations of the cell. LÄS MER

  5. 39. Mechanisms for TGF-β-Mediated Regulation of the Actin Filament System and Apoptosis

    Författare :Sofia Edlund; Pontus Aspenström; Maréne Landström; Tommy Andersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; TGF-beta; cytoskeleton; GTPases; mitogen-activated protein kinase kinase 3; TGF-beta-activated kinase 1; Apoptosis; Smad7; beta-catenin; p38 MAPK; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Transforming growth factor-β (TGF-β) is a member of a large superfamily of cytokines which participate in many different types of cellular processes, such as growth inhibition, cell migration, differentiation, cell adhesion, wound healing and immunosuppression. Alterations of TGF-β superfamily signalling results in several different disorders, including bone disease, vascular disease and cancer. LÄS MER

  7. 40. Neonatal Exposure to Anaesthesia and Adjuvants : Acute Effects on Cerebral Apoptosis and Neuroproteins, and Late  Behavioural Aberrations in Mice

    Författare :Emma Pontén; Anders Fredriksson; Torsten Gordh; Steen Henneberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; neonatal; apoptosis; bahaviour; clonidine; ketamine; propofol; theophyllamine; Medicin; Medicine;

    Sammanfattning : During a finite developmental phase – the brain growth spurt – the brain grows and matures at an accelerated rate. During this period the brain is more sensitive to harmful substances such as ethanol and environmental toxins than before or after. LÄS MER
