Multiple pathways of capillary permeability.

Multiple pathways of capillary permeability.

Morphological and physiological studies indicate multiple routes for transport across capillary endothelium. However, the identification of the morphological counterparts of specific transport processes (or the assignment of specific transport roles to morphologically identifiable pathways) has been only partly achieved: the contribution of endothelial cell membranes to transport of water and s...

Capillary permeability to macromolecules.

Intercellular cement and capillary permeability.

The passage of materials across a membrane consisting of cells, e.g., the cap& lary wall, requires a consideration of several structural tors. Environmental effects may be mediated through the exertion of may be purely nt of material passed through in a permeability characteristics of the and environmental f acchemical action on the structure of pressure on the membrane the membrane. or they ma...

What determines glomerular capillary permeability?

There have been exciting recent advances in our understanding of the structural and molecular biology of the glomerular slit diaphragm, as described in a report in this issue of the JCI. These findings, combined with data on the permeability of the basement membrane and evidence that the endothelium may be a more important barrier than often supposed, are allowing a clearer understanding to eme...

Capillary Permeability to Plasma Proteins.

ACCORDING to the classical hypothesis of Starling (1896) the exchange of water and small lipid-insoluble molecules across the capillary membrane is largely governed by the balance between hydrostatic and colloid osmotic pressures, the existence of the latter being dependent upon relative impermeability of the capillary membrane to plasma proteins. Starling's concept has been verified by direct ...
