The most commonly used drug delivery systems rely on diffusion to regulate release of target factors.
Steroid hormones are a group of lipophilic hormones that are believed to enter cells by simple diffusion to regulate diverse physiological processes through intracellular nuclear receptors.
This raises the general question of how α7-nAChRs lateral membrane diffusion is regulated.
Thus, Na+ diffusion may regulate CaTs in cells adjacent to acidified myocytes.
In summary, these data highlight the dynamic nature of CD81 and demonstrate a role for CD81 lateral diffusion to regulate HCV infection in a polarization-dependent manner.
TJs encircle cells at the apical end of the lateral membrane to form a paracellular diffusion barrier that regulates epithelial permeability, and an intramembrane diffusion barrier which restricts the apico-basolateral diffusion of membrane components.
The categorization of these branching patterns with respect to the TZ is important, because the TZ is considered to function as a diffusion barrier that regulates movement of membrane proteins into and out of the cilium (Nachury et al., 2010; Czarnecki and Shah, 2012; Reiter et al., 2012; Szymanska and Johnson, 2012).
Inter-bubble diffusion did not regulate bubble size in our apparatus because residence time in the fracture is relatively short.
For that reason, a ciliary 'gatekeeper' function has been postulated for CEP290 to maintain the integrity of the ciliary diffusion barrier and regulate the entry and exit of ciliary proteins16,23,24,25.
The hydrophobicity of the gas diffusion electrode was regulated by changing either the amount of Teflon (PTFE) content in the catalyst layer or baking temperature of the electrode.
Here, we study a large class of connections and reveal the role of curvature in the spine-neck connection in regulating diffusion flux through narrow necks.
