Force Barriers for Membrane Tube Formation

open access: yesPhysical Review Letters, 2005
We used optical tweezers to measure the force-extension curve for the formation of tubes from giant vesicles. We show that a significant force barrier exists for the formation of tubes, which increases linearly with the radius of the area on which the pulling force is exerted. The tubes form through a first-order transition with accompanying hysteresis.

The glomerular basement membrane as a barrier to albumin [PDF]

open access: yesNature Reviews Nephrology, 2013
The glomerular basement membrane (GBM) is the central, non-cellular layer of the glomerular filtration barrier that is situated between the two cellular components--fenestrated endothelial cells and interdigitated podocyte foot processes. The GBM is composed primarily of four types of extracellular matrix macromolecule--laminin-521, type IV collagen ...

TOPOLOGY AND BARRIER FUNCTION OF MEMBRANES IN THE LUNG [PDF]

open access: yesPediatric Research, 1981
The alveolo-capillary air-blood barrier of the lung is made of two thin cell layers, epithelium and endothelium, that limit the flow of solutes and fluid from blood plasma into the narrow interstitial space and into the very thin alveolar fluid lining associated with surfactant. The conditions for maintaining a thin dry air-blood barrier are discussed.
