  2. 21. Recognition requirements and regulatory events directing T cell responses

    Author : Martin Gullberg; Eva-Lotta Larsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T cell growth factor production; Lyt-2-positive T suppressor cell; Lyt-2-positive cytotoxic T lymphocytes; activation requirements of T lymphocytes; blocking of T cell functions;

    Abstract : The present study has considered cellular and molecular requirements in T cell responses. The central role of T cell growth factors (TCGF) in T cell responses prompted us to study the regulatory events directing TCGF production in lectin stimulated cultures. READ MORE

  4. 22. Affinity Biosensors for Carbahydrate-Protein Interactions using Surface Plasmon Resonance

    Author : Christina Jungar; Bengt Danielsson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : There is an increasing need for fast, accurate, and easy-to-use biosensors for applications in environmental, food, and pharmaceutical industry. In these thesis the interactions between immunoglobulins and lectins with their corresponding carbohydrate antigens are studied using surface plasmon resonance (SPR). READ MORE

  5. 23. Structural insights into glycoprotein transport and viral escape

    Author : Lucas Malard Velloso; Karolinska Institutet; Karolinska Institutet; []
    Keywords : X-ray crystallography; glycoprotein transport; endoplasmic reticulum; p58 ERGIC-53; MHC class I molecules; viral escape;

    Abstract : The correct trafficking of proteins through the secretory pathway is essential for the maintenance of cellular functions. Increasing evidence suggests that at least for some glycoproteins, export from the endoplasmic reticulum (ER) is mediated by interaction with cargo receptors. READ MORE

  6. 24. Identification of Virulence Factors in Nematode-Trapping Fungi - Insights from Genomics, Transcriptomics and Proteomics

    Author : Karl-Magnus Andersson; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nematode-trapping fungi; comparative genomics; comparative transcriptomics; proteomics; virulence factors; parasitism;

    Abstract : Nematode-trapping fungi are soil-living organisms with the unique ability to capture and infect free-living nematodes. The interest in studying these fungi arises from their potential use as biological control agents for plant- and animal-parasitic nematodes. READ MORE

  7. 25. Glycosylation in cancer and infection : the role of sialic acid

    Author : Yuecheng Zhang; Anette Wingren; Maria Stollenwerk; Lars Ohlsson; Martin Dufva; Malmö universitet; []
    Keywords : 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;

    Abstract : 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.
