  1. 11. Feeding state modulates nociception in C. elegans

    Författare :Marina Ezcurra; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : An important function of the nervous system is to respond to changes in the environment. The nematode C. elegans chemotaxes towards attractants and escapes noxious stimuli. Chemotaxis to salts requires the two ASE neurons ASEL and ASER, and escape responses require the nociceptive ASH neurons. LÄS MER

  3. 12. Understanding ageing : the role of mitochondria in determination of caenorhabditis elegans life span

    Författare :Ivana Bratic Hench; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :C. elegans;

    Sammanfattning : Mitochondria are organelles found in eukaryotic cells. They are involved in many vital cellular functions. Consequently, mitochondrial dysfunction leads to a variety of human disorders. Many studies of the last 50 years showed that mitochondria are involved in the regulation of physiological ageing.

  4. 13. Influence of gut microbiota on xenobiotic toxicity in a Caenorhabditis elegans model with a focus on arsenic and PFAS

    Författare :Jagadish Mangu; Jana Jass; Abul Mandal; Nektarios Tavernarakis; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C. elegans; physiological responses; gut microbe models; arse-nite; arsenate; PFAS; PFOS;

    Sammanfattning : Exposure to environmental toxins presents a hazard to humans. Inorganic metalloid- arsenic (As), organic chemicals- per and poly-fluoroalkyl substances (PFAS) are frequently detected in the environment. Exposure to As and PFAS is associated with multiple adverse effects in humans and animals. LÄS MER

  5. 14. C. elegans PAQR-2 ‒ A Regulator of Membrane Homeostasis

    Författare :Emma Svensk; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAQR; LRRIG; glucose; membrane fluidity; desaturase; homeoviscous adaptation;

    Sammanfattning : The progestin and adipoQ receptor (PAQR) protein family is characterized by a 7-transmembrane domain, and a topology reversed that of G-protein coupled receptors, i.e. the N-terminus resides in the cytoplasm. LÄS MER

  7. 15. Membrane Fluidity Regulation: From C. elegans to mammalian cells

    Författare :Ranjan Devkota; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAQR-2; adiponectin receptors; IGLR-2; saturated fats; membrane fluidity; fatty acid desaturation; unsaturated fatty acid; membrane homeostasis;

    Sammanfattning : Biological membranes are primarily an assembly of lipids and proteins. Collectively, these constituents within a phospholipid bilayer determine the physical membrane properties such as fluidity, viscosity, thickness, packing and permeability. Maintenance of membrane properties within acceptable margins, i.e. LÄS MER
