  2. 11. The role of nuclear envelope proteins in chromatin organization, differentiation and disease

    Author : Cecilia Bergqvist; Einar Hallberg; Philippe Collas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear envelope proteins; chromatin organization; epigenetics; differentiation; quantitative image analysis; Samp1; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : In eukaryotes the genetic material is separated from the cytoplasm by the nuclear envelope (NE), consisting of the outer and inner nuclear membrane, the nuclear lamina and the nuclear pores. The genetic material is highly structured with transcriptionally inactive heterochromatin enriched at the nuclear periphery and transcriptionally active euchromatin in the nuclear interior.

  4. 12. Lipid Nanotube Networks: Shape Transitions and Insights into the Dynamics of Self-Organization

    Author : Tatsiana Lobovkina; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular nanotube; shape transition; enzymatic reaction; nanotube knot; self-organization; liposome; lipid nanotube; lipid vesicle; nanotube-vesicle network;

    Abstract : Nanotube-vesicle networks (NVNs) are simplified models of cell membrane tubular systems which are dynamic transportation routs for molecular cargoes in biological cells. The presented work describes dynamic properties of NVNs such as self-organization, shape and topology transformations; moreover, specific geometric properties of the networks are used for controlling enzymatic reactions.

  5. 13. The influence of adhesion molecules on binding and protein organization in cell contacts

    Author : Tommy Dam; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; T cell; SLBs; Calcium Signaling; TIRF microscopy; Two-Dimensional affinity; Protein Segregation; Protein Organization; Protein Height;

    Abstract : Interactions between immune cells such as T cells and antigen-presenting cells (APCs) are integral for mounting an adaptive immune response. The interaction between the T cell receptor (TCR) and the antigen-presenting major histocompatibility complex (pMHC) on a contacting T cell and APC, is widely accepted to be the key interaction.

  6. 14. 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

  7. 15. RICH-1, a Multifunctional RhoGAP Domain-containing Protein, Involved in Regulation of the Actin Filament System and Membrane-trafficking

    Author : Ninna Richnau; Pontus Aspenström; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Rho GTPase; RhoGAP; actin; BAR domain; membrane-trafficking; formin homology proteins; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : The Rho GTPases, which are related to the Ras family of proto-oncogenes, have been found to have important roles in regulating the morphogenic and migratory properties of eukaryotic cells. In addition, these proteins have been shown to regulate aspects of cell signaling, cell growth, cell division and cell survival. READ MORE
