  2. 1. Exploring the Interplay of Lipids and Membrane Proteins

    Author : Candan Ariöz; Åke Wieslander; Daniel O. Daley; Malcolm East; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane lipids; membrane proteins; anionic lipids; membrane remodeling; intracellular vesicles; model membrane systems; glycosyltransferase; Escherichia coli; lipid composition; fatty acid modification; membrane curvature; bacterial homeoviscous adaptation; Biochemistry; biokemi;

    Abstract : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. READ MORE

  4. 2. Interaction of Calcium Ions with Lipid Membranes

    Author : Baharan Ali Doosti; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phospholipid bilayer membrane; membrane dynamics; micromanipulation; calcium ions; cell migration.; membrane nanotube; membrane tubular protrusions; calcium ion concentration gradient; membrane bending; giant unilamellar vesicle;

    Abstract : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

  5. 3. Non-canonical ATG8 conjugation in ESCRT-driven membrane remodeling processes

    Author : Anastasia Knyazeva; Yao-Wen Wu; Richard Lundmark; Sascha Martens; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATG8 conjugation; Endosomal Sorting Complex Required for Transport; membrane remodeling; chemical genetics;

    Abstract : ATG8 family proteins have the unique ability to conjugate to membrane lipids. Initially identified as a hallmark of autophagy, ATG8 lipidation is emerging as an important regulator of a growing list of non-degradative cellular functions. READ MORE

  6. 4. Molecular and structural patterns of guided bone regeneration (GBR). Experimental studies on the role of GBR membrane and bone substitute materials

    Author : Ibrahim Elgali; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regenerative medicine; biomaterials; bone substitute; calcium phosphate; guided bone regeneration; membrane; strontium; bone defect; bone remodeling; inflammation; cytokines; chemokines; growth factors; gene expression; histomorphometry; in vivo;

    Abstract : The mechanisms of guided bone regeneration (GBR) and bone healing with calcium phosphate (CaP) bone substitutes are not fully understood. The major aim of this thesis was to determine the relationship between the bone formation in bone defects and the cellular distribution and activities in association with CaP materials and/or with GBR membrane.

  7. 5. Cellular remodeling in response to nutrient exhaustion : From membrane contact sites to autophagy

    Author : Mahsa Ebrahimi; Sabrina Büttner; Cristina Mazzoni; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aging and longevity; yeast; phosphate restriction; interorganellar communication; autophagy; MVB pathway; NVJs; lipid droplets; nutritional regimes; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Adaptation to fluctuating environments is critical for cellular fitness and survival. Cells need to sense changes in their surroundings and quickly adjust cellular homeostasis and metabolism accordingly. READ MORE
