  2. 1. Lineage stability and effector function of CD4+FOXP3+ regulatory T cells

    Author : Christina Seitz; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This work focuses on regulatory T (Treg) cell biology in the context of defining the role of forkhead box protein 3 (FOXP3) isoform expression and Treg mediated suppression via CTLA-4 (cytotoxic T-lymphocyte-associated protein 4). Treg cells are crucial in maintaining immunological tolerance and they in part act by suppressing dendritic cells (DCs). READ MORE

  4. 2. Ions colliding with Polycyclic Aromatic Hydrocarbons and Fullerenes

    Author : Fabian Seitz; Henning Schmidt; John Tanis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : In this thesis a series of experiments on collisions between atomic projectile ions at keV energies and target vapors of either isolated molecules or van der Waals clusters is presented and analyzed. The atomic ions are produced in an Electron Cyclotron Resonance (ECR) ion source, accelerated and guided into the target volume. READ MORE

  5. 3. Exploring molecular interactions between polypeptide conjugates and protein targets : Manipulating affinity by chemical modifications

    Author : Aleksandra Balliu; Lars Baltzer; Oliver Seitz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polypeptide conjugates; protein targets; molecular recognition; affinity enhancement; conjugation;

    Abstract : In this thesis molecular interactions between polypeptide conjugates and protein targets were investigated. Polypeptides were derivatized with small organic molecules, peptides and oligonucleotides. New strategies were developed with the aim to increase affinities for proteins of biological interest.

  6. 4. Describing Interstitials in Close-packed Lattices: First-principles Study

    Author : Noura Al-Zoubi; Levente Vitos; Se Kyun Kwon; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Describing interstitial atoms in intermetallics or simple mono-atomic close-packed metals is a straightforward procedure in common full-potential calculations. One establishes a sufficiently large supercell, introduces the interstitial impurity and performs the electronic structure and total energy calculation. READ MORE
