  1. 1. Functionalization of spider silk with affinity and bioactive domains via genetic engineering for in vitro disease diagnosis and tissue engineering

    Författare :Naresh Thatikonda; My Hedhammar; Hanna Dams Kozlowska; KTH; []
    Nyckelord :affinity domains; artificial ECM; basic fibroblast growth factor; functionalization; mammalian cell culture; micro-and nano arrays; partial spider silk; single chain variable fragments; Bioteknologi; Biotechnology;

    Sammanfattning : In the recent past, spider silk has drawn significant attention from researchers mainly due to its distinguished mechanical strength, elasticity, biocompatibility and biodegradability. Technological advancements in genetic engineering have resulted in methods for creation of partial spider silk proteins. LÄS MER

  3. 2. Vascular remodelling and circulating basement membrane fragments in abdominal aortic aneurysm

    Författare :Mari Holsti; Malin Sund; Anders Wanhainen; Joakim Nordanstig; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AAA; extracellular matrix; vascular remodelling; collagen; inflammation; Surgery; kirurgi;

    Sammanfattning : An abdominal aortic aneurysm (AAA) is a degenerative disease, characterized by advanced inflammation and extracellular matrix (ECM) remodelling. Enhanced protease activity mediated by cytokines results in the degradation of ECM proteins, leading to the generation of different bioactive fragments. LÄS MER

  4. 3. The Impact of the Neuropeptide Substance P (SP) Fragment SP1-7 on Chronic Neuropathic Pain

    Författare :Anna Jonsson; Fred Nyberg; Mathias Hallberg; James Zadina; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropathic pain; substance P SP ; SP1-7; bioactive fragments; spared nerve injury; spinal cord injury; streptozotocin-induced diabetes; allodynia; hyperalgesia; peptidomimetics; cerebrospinal fluid; spinal cord stimulation; radioimmunoassay; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : There is an unmet medical need for the efficient treatment of neuropathic pain, a condition that affects approximately 10% of the population worldwide. Current therapies need to be improved due to the associated side effects and lack of response in many patients. LÄS MER

  5. 4. Proteolytic processing of the Alzheimer APP protein family during neuronal differentiation

    Författare :Sofia Holback; Kerstin Iverfeldt; Nigel Hooper; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APP; APLP1; APLP2; differentiation; processing; retinoic acid; secretase; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : Increased amyloid-β (Aβ) load in the brain, neurite degeneration, neuronal loss, and decreased levels of several neurotrophins are among the characteristics of Alzheimer’s disease (AD). Generation of Aβ occurs when the amyloid precursor protein (APP) is proteolytically processed by β- and γ-secretases in the amyloidogenic pathway. LÄS MER

  7. 5. Galanin receptor ligands : Design, synthesis, characterization and biological effects

    Författare :Kristin Webling; Ülo Langel; Tore Bengtsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Galanin is a 29/30 amino acid long bioactive peptide discovered over 30 years ago when C-terminally amidated peptides were isolated from porcine intestines. The name galanin originates from a combination of the first and last amino acids - G from glycine and the rest from alanine. LÄS MER
