  1. 1. Melanophore signaling : regulation and application

    Författare :Tony P. M. Andersson; Ethan Lerner; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Melanophores are pigment-containing cells responsible for quick physiological color changes in lower vertebrates due to redistribution of melanosomes, pigment granules. We have studied melanophores from African clawed frog, Xenopus laevis. LÄS MER

  3. 2. The Interleukin-1 family of proteins in the brain and adrenal gland : regulation in response to bacterial LPS

    Författare :Susanne Tingsborg; Fred J.H. Tilders; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

    Sammanfattning : Interleukin-1 (IL-1) is mediating diverse physiological conditions as inflammatory response, fever and sickness behaviour but also, via activation of the hypothalamus-pituitary-adrenal (HPA)-axis, the release of the anti-inflammatory adrenocorticoids. The neuroendocrine system as well as the central nervous system (CNS) is involved in the regulation of these conditions in the body. LÄS MER

  4. 3. Characterization of the DNA-Binding Properties of the Cyanobacterial Transcription Factor NtcA

    Författare :Susanne Wisén; Bengt Mannervik; Enrique Flores; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; NtcA; transcription regulation; cyanobacteria; redox regulation; DNA binding; nitrogen fixation; Anabaena PCC 7120; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Nitrogen is an essential building block of proteins and nucleic acids and, therefore, crucial for the biosphere. Nearly 79 % of the air consists of nitrogen, but in the form of nitrogen gas (N2), which cannot be utilized by most organisms. LÄS MER

  5. 4. Genetic regulation of autoimmune neuroinflammation

    Författare :Kristina Becanovic; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MS; EAE; QTL; gene regulation; linkage analysis;

    Sammanfattning : Multiple sclerosis (MS) is a complex disease characterized by inflammation and demyelination in the central nervous system (CNS), causing neurological deficits. Although there is an increased familial aggregation rate and evidence for a genetic influence on disease susceptibility, environmental factors are also of importance. LÄS MER

  7. 5. Molecular Mechanisms in Vascular Endothelin B Receptor Up-Regulation

    Författare :Erik Uddman; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; reverse; in vitro pharmacology; organ culture; Endothelin receptors; up-regulation;

    Sammanfattning : Cardiovascular diseases are characterized by changes in morphology and function of the blood vessels. Different signalling molecules are involved in these changes. Endothelin-1 (ET-1) is one of the most potent signalling molecules found in man. Its actions are mediated by two receptors, the ETA and the ETB receptors. LÄS MER
