  1. 16. Peptide-Liposome Model Systems for Triggered Release

    Författare :Camilla Skyttner; Daniel Aili; Karin Enander; Fredrik Höök; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Liposomes are widely used in drug delivery to improve drug efficacy and to reduce side effects. For liposome-encapsulated drugs to become bioavailable and provide a therapeutic effect they must be released, which typically is a slow process that primarily relies on passive diffusion, liposome rupture or endocytotic uptake.

  3. 17. Glycosylation in cancer and infection : the role of sialic acid

    Författare :Yuecheng Zhang; Anette Wingren; Maria Stollenwerk; Lars Ohlsson; Martin Dufva; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer; sialic acids; receptor; molecularly imprinted polymers; SARS-CoV-2; fluorescence; Health and society; Hälsa och samhälle;

    Sammanfattning : Sialic acids (SA), a group of nine-carbon backbone monosaccharides are abundantly expressed in vertebrates. They are usually linked to the terminal of glycan chains and play crucial roles in many biological processes, including cell adhesion, cell-cell interactions, immune modulation, cancer cell migration and invasion, as well as viral infections.

  4. 18. Engineering the extracellular matrix to model diseases and orchestrate regeneration

    Författare :Zackarias Söderlund; Lungbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The extracellular matrix is not only a scaffold to which cells attach, but it is also a matrix that communicates cell signals. Because of the interplay between cells and the extracellular matrix, changes in the extracellular matrix can steer cell fate. LÄS MER

  5. 19. Biochemical and functional properties of mammalian bone alkaline phosphatase isoforms during osteogenesis

    Författare :Cecilia Halling Linder; Per Magnusson; Elvar Theodorsson; Göran Andersson; Torgny Stigbrand; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The human skeleton is a living and dynamic tissue that constantly is being renewed in a process called bone remodeling. Old bone is resorbed by osteoclasts and new bone is formed by osteoblasts. LÄS MER

  7. 20. Microgels as Carriers for Antimicrobial Peptides : Surface-bound microgels, and factors affecting peptide interactions

    Författare :Lina Nyström; Martin Malmsten; Per Hansson; L. Andrew Lyon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antimicrobial peptides; Biomaterial coating; Drug delivery; Host defence peptides; Microgels; pH-responsive; Surface-bound; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    Sammanfattning : With a growing number of multi-resistant bacteria against conventional antibiotics, there is an urgent need to identify new antimicrobial therapeutics. One example that has gained considerable interest is antimicrobial peptides (AMPs). LÄS MER
