    Sammanfattning : Amyloidoses comprise a group of gain-of-toxic function protein misfolding diseases, in which normally soluble proteins in their functional state undergo conformational changes into highly organized and generally intractable thread-like aggregates, termed amyloid fibrils. These structures accumulate predominantly in the extracellular space but growing evidence suggests that amyloids may start to form intracellularly. LÄS MER

  2. 2. Hereditary transthyretin amyloidosis (ATTR V30M) from genes to genealogy

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Nina Norgren; Ole Suhr; Alda Sousa; [2014]

    Sammanfattning : Background: Hereditary transthyretin amyloidosis is an autosomal dominant disease with a reduced penetrance. The most common mutation in Sweden is the V30M mutation in the transthyretin gene. Clustering areas of the disease can be found in Northern Sweden, Portugal, Brazil and Japan, although sporadic cases exist worldwide. LÄS MER

  3. 3. The heart in hereditary transthyretin amyloidosis clinical studies on the impact of amyloid fibril composition

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Björn Pilebro; Ole Suhr; Henning Mölgaard; []

    Sammanfattning : Background Hereditary transthyretin amyloid (ATTRm) amyloidosis is a systemic disease mainly affecting the peripheral nervous system and the heart. The disease is inherited in an autosomal dominant manner with a varying penetrance. It is caused by mutations in the transthyretin (TTR) gene. Today more than 100 disease causing mutations are known.

  4. 4. Transthyretin and the transthyretin-related protein: A structural study

    Detta är en avhandling från Umeå : Umeå centrum för molekylär patogenes (UCMP) (Teknisk-naturvetenskaplig fakultet)

    Författare :Erik Lundberg; A. Elisabeth Sauer-Eriksson; Lennart Sjölin; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transthyretin; Transthyretin-related protein; X-ray crystallography; Protein structure; Amyloidosis; NATURAL SCIENCES Chemistry Biochemistry Structural biology; NATURVETENSKAP Kemi Biokemi Strukturbiologi;

    Sammanfattning : Transthyretin (TTR) is one of several proteins involved in amyloid disease in humans. Unknown conformational changes of the native state of TTR result in aggregation of TTR molecules into amyloid fibrils, which accumulate in extracellular tissues. This may result in different clinical symptoms, e.g. LÄS MER

  5. 5. Heparan Sulfate Dependent Mechanisms of Amyloidosis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Fredrik Noborn; Jin-ping Li; Ulf Lindahl; Giampaolo Merlini; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amyloidosis; Heparan sulfate; Transthyretin; Serum amyloid A; Amyloid-beta; lipoproteins; Medical Biochemistry; Medicinsk biokemi;

    Sammanfattning : A common theme in amyloid disorders is the deposition of disease-specific protein aggregates in tissues. Amyloid proteins bind to heparan sulfate (HS), a sulfated glycosaminoglycan, and HS has been found to promote the aggregation process. LÄS MER
