  2. 1. Zinc-enriched neurons in the spinal cord, cerebellum and peripheral sympathetic system

    Author : Zhan-You Wang; Göteborgs universitet; []
    Keywords : autometallography; axonal transport; confocal laser scanning microscopy; immuno-electron microscopy; immunofluorescence; inhibitory neurons; sympathetic neurons; synaptic vesicles; zinc ions; zinc transporter;

    Abstract : Zinc ions are abundant in the nervous system and are involved in many biological functions. Most zinc is tightly bound to macromolecules, whereas a small fraction of zinc exists in synaptic vesicles of the zinc-enriched (ZEN) neurons, and can be visualized using various histochemical techniques, including autometallography (AMG).

  4. 2. Oxidative stress, macrophages, iron, and atherosclerosis

    Author : Wei Li; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Macrophages have a great capacity to take up exogenous material, such as oxidatively modified low density lipoproteins (oxLDL) and different sources of iron containing structures. OxLDL is taken up into macrophage lysosomes by receptor-mediated endocytosis, but poorly degraded, resulting in foam-cell formation. READ MORE

  5. 3. Insulin-Producing Cells, Iron, Oxidative Stress, and Lysosomal Pathology

    Author : Beata Teresa Olejnicka; Enrique Cadenas; Linköpings universitet; []
    Keywords : Insulin-producing cells; redox-active iron; oxidative stress; lysosomes; desfenioxamine; MEDICINE; MEDICIN;

    Abstract : Accumulating evidence suggests that injnries caused by oxygen-derived radicals contribute to the destruction of pancreatic islet ß-cells in autoinnnune diabetes mellitus (diabetes type I, or IDDM). Oxidative stress may be caused by an enhanced production of oxygen-derived radicals, or by a decreased scavenging of such molecules. READ MORE

  6. 4. Iron and macrophages in atherogenesis

    Author : Xi Ming Yuan; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Oxidation of low density lipoprotein (LDL) may result in its uptake by macrophages and ensuing foam cell formation. Thus, oxidised LDL may play an important role in atherogenesis. Extensive in vitro evidences are in favour of the notion that LDL oxidation by cells present in atherosclerotic plaques requires the presence of transition metals. READ MORE
