  2. 11. Phospholipase A2 in nerve injury and axonal outgrowth

    Author : Marie Hornfelt; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neurology; cell death; apoptosis; leukotrienes; arachidonic acid; M-type receptor; secretory phospholipase A2; cytosolic phospholipase A2; sciatic nerve; dorsal root ganglia; growth cone; axonal outgrowth; nerve injury; peripheral nerve regeneration; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Animal physiology; Djurfysiologi;

    Abstract : This thesis deals with processes coupled to injury in the peripheral nervous system (PNS), with a general aim to investigate the role of phospholipase A2 (PLA2) enzymes in axonal outgrowth. The axonal outgrowth of dorsal root ganglia (DRG) neurons in vitro was reduced by several different inhibitors of PLA2 activity and enhanced by an activator of this enzyme. READ MORE

  4. 12. Novel Immunotherapies and Immunoregulation in a Chronic Inflammatory Disease of the Central Nervous System

    Author : Shahram Lavasani; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neurologi; neurophysiology; neuropsychology; Neurology; Djurfysiologi; Animal physiology; probiotics; immunotherapy; CD1; T-cell; CNS; inflammation; EAE; MS; neuropsykologi; neurofysiologi;

    Abstract : Multiple sclerosis (MS) is a chronic inflammatory disease of central nervous system (CNS) which is thought to arise from a breakdown of immunological tolerance in CD4 cells. The aim of this thesis is to improve our understanding of regulation mechanisms of T cell-dependent chronic inflammation in the CNS and explore ways to overcome the onset and progression of the disease, which can be an important step forward in the treatment of MS.

  5. 13. Induced Growth and Precocious Maturation of the Digestive System in Suckling Rats and Pigs after Exposure to Red Kidney Bean Lectin

    Author : Ann Linderoth; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neuropsykologi; neurofysiologi; Neurologi; neurophysiology; neuropsychology; Neurology; Fysiologi; Physiology; Djurfysiologi; Animal physiology; sucrase; lactase; amylase; trypsin; weaning; small intestine; glucocorticoids; endocytosis; dissacchridases; intestinal permeability; PHA; pancreas; Development; phytohaemagglutinin;

    Abstract : The timing of the postnatal development of the gastrointestinal (GI) tract in mammals is influenced by dietary and hormonal factors. It was hypothesized that accelerated GI cell turnover during maturation would result in a precoucios conversion to more mature digestive functions. READ MORE

  6. 14. JNK/c-Jun Signaling and Peripheral Nerve Regeneration

    Author : Charlotta Lindwall; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neuropsykologi; neurofysiologi; neurophysiology; Neurologi; neuropsychology; Neurology; Djurfysiologi; Animal physiology; JNK; signal transduction; nerve regeneration;

    Abstract : The events associated with axonal injury in the peripheral nervous system (PNS) have been described in detail. However, the molecular mechanisms underlying the regenerative response, or neuronal cell death, following axonal injury are poorly understood. READ MORE

  7. 15. Intestinal permeability : a parameter of mucosal dysfunction

    Author : Pål Lundin; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptide; N-acetylcysteine; Medium-chain glyceride; Mannitol; Macromolecules; Lipid; Kinetics; In vivo; In vitro; In situ; Intestine; Injury; Inflammation; HLA-B27; HCl; Epithelium; Enhancer; dDAVP; 51Cr-EDTA; BSA; Absorption; Albumin; Permeability; Animal physiology; Djurfysiologi;

    Abstract : The gastrointestinal tract has two opposing functions; to absorb nutrients and electrolytes, and to act as a barrier towards hazardous and non-nutritional substances. In the present thesis the barrier function of the gastrointestinal tract was studied in animal models in vivo, in situ and in vitro. READ MORE
