Viral subversion of host cell membrane trafficking
Enveloped viruses acquire their membrane coat from the plasma membrane or intracellular organelles and rely on cellular machinery to facilitate envelopment and egress of virus progeny. This thesis examines egress-related interactions between host cell factors and proteins of two different enveloped …

Probing cell membrane dynamics using plasmon coupling microscopy
The plasma membrane of mammalian cells is depicted as a two-dimensional hybrid material which is compartmentalized into submicron-sized domains. These membrane domains play a pivotal role in cellular signaling processes due to selective recruitment of specific cell surface receptors. The structural …

Rotational motion and organization studies of cell membrane proteins
Cell membranes are dynamic structures with complex organization. The complexity of the cell membrane arises from intrinsic membrane structure, membrane microdomains within the plasma membrane and the membrane cytoskeleton. Plasma membrane receptors are integral membrane proteins with diverse …

Specificity of Interaction of Antimicrobial Peptide with Cell Membrane
… development. AMPs primarily target bacterial cell membranes. Their hydrophobic side chains contribute both to membrane interaction and to peptide stability. This study investigates the interactions of a series of small AMPs with liposomes mimicking bacterial membranes (DOPC/DOPG, 7:3 molar …

Molecular Basis of Cell Membrane Adaption Against Daptomycin in Enterococcus faecalis
… last-resort lipopeptide antibiotic that disrupts cell membrane (CM) and peptidoglycan homeostasis (Grein et al., 2020a; Müller et al., 2016a). Enterococcus faecalis has developed a sophisticated mechanism to avoid daptomycin killing by redistributing CM anionic phospholipids away from the septum. …

The missing dimension of cell membrane organization. Study on cubic membrane structure and function
Membranes are of fundamental importance for biological systems. They provide for cellular compartmentalization and control of the internal cell environment. The biophysical properties of the membrane lipids and proteins play a key role in determining the membrane morphology and geometry. Far from …

Development of an Experimentally Validated Non-linear Viscoelastic Viscoplastic Model for a Novel Fuel Cell Membrane Material
The proton exchange membrane (PEM) is a key component in proton exchange membrane fuel cells (PEMFCs). During standard fuel cell operation, the PEM degrades due to cyclic hygrothermal loads, resulting in performance loss or total failure. Improvement of current PEM materials and development of …

Studies on the nature of red blood cell hemolysis on storage and the nature of the red blood cell membrane acetylcholinesterase
… the acetylcholinesterase (AChE) of the red blood cells (RBC) is concerned with the maintenance of the integrity of the cells Anderson and Pethica (9) have reported that in stored citrated blood, the release of RBC ^ChE seemed to coincide with the onset of hemolysis. In vivo (10, 11) and in vitro …
