  2. 1. Mechanisms involved in amyloid induced cytotoxicity

    Author : Johan Östman; Lars Lannfelt; Umeå universitet; []
    Keywords : amyloid; transthyretin; cytotoxicity; apoptosis; caspases; aggregation; molekylärbiologi; Molecular Biology;

    Abstract : Amyloidoses comprise a group of diseases where normal or mutated protein precipitates into amyloid fibrils. The deposition of fibrils causes dysfunction of organs and toxicity to nervous tissue. Up to date, 24 different proteins and peptides are known to be able to form amyloid fibrils. READ MORE

  4. 2. Effects of the host defense peptide LL-37 on human cells : Immunomodulation and cytotoxicity

    Author : Sara Bodahl; Kärlfysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LL-37; Host defense peptides; Cathelicidin; Inflammation; Cytotoxicity; TLR3; Poly I:C;

    Abstract : The human host defense peptide LL-37 has an essential role in the first line of defense against invading pathogens. This cathelicidin is mainly produced by immune cells and epithelial cells aligning the mucosal areas and is normally upregulated upon infection and inflammation. READ MORE

  5. 3. Structural studies of heterogeneous amyloid species of lysozymes and de novo protein albebetin and their cytotoxicity

    Author : Vladimir Zamotin; Ludmilla Morozova-Roche; Daniel Otzen; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; amyloid; cytotoxicity; atomic force microscopy; Biophysics; Biofysik;

    Abstract : A number of diseases are linked to protein folding problems which lead to the deposition of insoluble protein plaques in the brain or other organs. These diseases include prion diseases such as Creutzfeld-Jakob disease, Alzheimer's disease, Parkinson's disease and type II (non-insulin dependent) diabetes. READ MORE

  6. 4. Selenium cytotoxicity in cancer

    Author : Marita Wallenberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Selenium is an essential trace element, present in the 21st amino acid selenocysteine, which is specifically incorporated into selenoproteins. Today, there are 25 identified selenoproteins in humans, whereof many comprises redox active functions to uphold the intracellular redox balance. READ MORE

  7. 5. Cytotoxic Compounds of Plant Origin – Biological and Chemical Diversity

    Author : Petra Lindholm; Anders Backlund; Lars Bohlin; Kristín Ingólfsdóttir; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacognosy; pharmacognosy; cytotoxicity; antitumour; Nuphar alkaloid; cyclotide; thionin; cardiac glycoside; Farmakognosi; Pharmacognosy; Farmakognosi;

    Abstract : The development of resistance by tumour cells to chemotherapeutic agents is a major problem in cancer treatments. One way to counter this is to find compounds with cytotoxic mechanisms other than those of drugs in clinical use today. READ MORE
