  1. 11. Saliva: a cell suspension of epithelial cells harboring the antimicrobial peptide LL-37 and the growth factor EGF

    Författare :Alexandra Aidoukovitch; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Saliva; Oral health; Innate immunity; Cathelicidin; LL-37; Host defense peptides; EGF; Saliva; Oral health; Innate immunity; Cathelicidin; LL-37; Host defence peptides; EGF;

    Sammanfattning : Saliva plays a crucial role in maintaining oral health through its physical and chemical properties that provide various protective functions. One of its essential components is the human host defense peptide LL-37, which is produced by immune cells and epithelial cells, and participates in the first line of defense against pathogens.

  3. 12. Progressive models of Parkinson's disease : behavioural and neurochemical analyses

    Författare :Alexandra Alvarsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Parkinson’s disease (PD) is a common neurodegenerative disorder diagnosed based on the presence of motor symptoms, including resting tremor, postural impairment, bradykinesia and rigidity. The pathological hallmarks are degeneration of midbrain dopaminergic neurons and the accumulation of inclusions containing the misfolded protein α-synuclein (termed “Lewy bodies”) throughout the nervous system.

  4. 13. Fluorescence microscopy studies of interactions between monomeric α-Synuclein and lipid membranes

    Författare :Alexandra Andersson; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Total internal reflection fluorescence microscopy; single vesicle imaging; single molecule imaging; protein-lipid interactions; α-Synuclein;

    Sammanfattning : α-Synuclein (α-Syn), is an intrinsically disordered protein present in the substantia nigra part of the brain. α-Syn is commonly known to associate with lipid membranes containing anionic lipids. LÄS MER

  5. 14. Hemicelluloses from Agricultural and Forestry Crops Isolation, Characterisation, and Enzymatic Hydrolysis

    Författare :Alexandra Andersson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; Physical chemistry; Fysikalisk kemi; enzymology; hydrogels; Plant biochemistry; Växtbiokemi; Proteins; a-galactosidase; b-mannanase; hemicellulase; corn fibre; barley husks; spruce; size-exclusion chromatography; arabinoxylan; microwave irradiation; steam pretreatment; membrane filtration; hemicellulose; galactoglucomannan;

    Sammanfattning : Hemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. LÄS MER

  7. 15. Influence of kynurenic acid on dopamine neurotransmission : implications for schizophrenia

    Författare :Alexandra Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Kynurenic acid (KYNA) belongs to the kynurenines, a group of metabolically related compounds derived from the amino acid tryptophan. It is an antagonist of glutamate- and α7 nicotinic acetylcholine (α7nACh) receptors. Increased levels of KYNA have been observed in the cerebrospinal fluid and postmortem brains of patients with schizophrenia. LÄS MER
