    Sammanfattning : Virus infection is initiated by the attachment of a virion to a susceptible cell’s plasma membrane, in a highly dynamic and well-orchestrated process that encompasses various steps and engages numerous viral and cellular factors. These dynamic steps may include initial non-specific binding to ubiquitous cell-membrane ligands, diffusion across the membrane to a suitable entry site and virus engagement with various receptors and co-receptors on the cell surface.

    Sammanfattning : G protein-coupled receptors (GPCRs), also known as seven transmembrane (7TM) receptors,is the largest family of cell surface receptors. These receptors play a key role in transmittinga wide variety of signals across the cell membrane and are involved in physiologicalprocesses such as sensory transduction, cell-cell communication, neuronal transmission,and hormonal signaling.

  3. 3. Feedback in Small Systems -A Stochastic Thermodynamic Perspective

    Författare :Regina Schmitt; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2018:Schmitt;

    Sammanfattning : Recent advances in nanotechnology and the accompanying development oftechniques that operate and manipulate systems on the micro- and nanometer scale have driven the development of stochastic thermodynamics. This isa theory that can describe small systems far from equilibrium, where the fluctuations are of the same order of magnitude as the mean values. LÄS MER
