Implications of lipid microdomains for membrane curvature, budding and fission

Current Opinion in Cell Biology, 2001
Recent studies have highlighted the importance of monolayer and bilayer curvature for the budding and fission of biological membranes. Other lines of research, addressing the structure of planar biological membranes, have revealed the existence of cholesterol-based membrane microdomains.

Budding Dynamics of the Lipid Membrane

Journal of Nanoscience and Nanotechnology, 2011
Liposomes are widely used in industrial engineering systems including cosmetics and pharmaceutical and biotechnological applications. A fundamental understanding of the dynamics of lipid bud formation is required to efficiently produce various high-technological liposomes with well-controlled sizes and shapes.

Zinc localization in taste bud membranes

Biological Trace Element Research, 1983
Zinc was measured by flame aspiration atomic absorption spectrophotometry in homogenates and in enriched fractions and subfractions from bovine taste bud membranes and from surrounding control tissues that contained no taste buds. Zinc was found in significantly higher concentrations in tissues containing taste buds and increased in concentration as ...

Budded membrane microdomains as tension regulators

Physical Review E, 2006
We propose a mechanism by which changes of the mechanical tension of a composite lipid membrane are buffered by the invagination of membrane domains. We show that domain invagination, driven by differences in chemical composition, is a first-order transition controlled by membrane tension.

Domain-induced budding in buckling membranes

The European Physical Journal E, 2007
We present a phase field model on buckling membranes to analyze phase separation and budding on soft membranes. By numerically integrating dynamic equations, it turns out that the formation of caps is greatly influenced by the presence of a little excess area due to the surface area constraint. When cap-shaped domains are created, domain coalescence is

Endocytosis: clathrin-mediated membrane budding

Current Opinion in Cell Biology, 2007
Clathrin-dependent endocytosis is the major pathway for the uptake of nutrients and signaling molecules in higher eukaryotic cells. The long-held tenet that clathrin-coated vesicles are created from flat coated plasma membrane patches by a sequential process of invagination, bud formation and fission recently received strong support from the results of

Radiation Effects on Bovine Taste Bud Membranes

Radiation Research, 1982
In order to investigate the mechanisms of radiation-induced taste loss, the effects of radiation on preparations of enriched bovine taste bud membranes were studied. Taste buds containing circumvallate papillae, and surrounding control epithelial tissue devoid of taste buds, were obtained from steers and given radiation doses of 0-7000 cGy (rad ...

On the role of anisotropy of membrane constituents in formation of a membrane neck during budding of a multicomponent membrane

Journal of Biomechanics, 2007
The expression for the isotropic membrane bending energy was generalized for the case of a multicomponent membrane where the membrane constituents (single molecules or small complexes of molecules-membrane inclusions) were assumed to be anisotropic.

Mechanosensitivity of Membrane Budding and Trafficking

2018
Intracellular compartments continually exchange material transported by small vesicles or tubules, which are formed in the membrane of the donor compartments and eventually fuse with the membrane of the receptor compartments. The formation and fission of a membrane bud giving rise to a new object and the fusion are controlled to some extent by the ...

Membrane Traffic: Vesicle Budding and Fusion

2006
Tight control of the flux of membrane components through vesicle budding and fusion is essential to cellular organization, giving rise to subcellular compartments with distinct functions. Cargo is generally selected for inclusion into vesicles by specific sorting signals, which are recognized by adaptor proteins, that link to protein components of ...
