Witte, "Intrinsic optical signals in rat neocortical slices measured with near-infrared dark-field microscopy reveal changes in extracellular space
," Journal of Neuroscience, vol.
A release of S1P into the extracellular space
might demonstrate another route of disposing S1P.
It will be of particular interest to evaluate changes in the nerve fiber layer, ganglion cell density, photoreceptor abnormalities, retinal thickness, and the quantification of the extracellular space
of the retina.
Exocytosis is an evolutionary trait of eukaryotic cells that leads in a given secretory cell to a release of chemical content by a fast mechanism into the extracellular space
and thus to communication with neighboring cells.
The coincidence of measured sulfate space and our physical determination of extracellular fluid indicated an extracellular space
of about 40% in C.
This loss of body weight appears to result largely from physiologic contraction of the extracellular space
after birth [4,5].
Under necrotic condition, contents of the cytosol are dispersed into the extracellular space
due to cellular distress or damage .
Beginning with the work of Geoffrey Burnstock in the 1970s, a role for adenosine triphosphateATP (which is a ubiquitous energy source) and its metabolites (e.g., adenosine diphosphate [ADP] and adenosine) in the extracellular space
acting on cell surface receptors has now been established.
They can be found next to microfibrils or collagen fibrils, but also free in the extracellular space
[ILLUSTRATION FOR FIGURE 19 OMITTED].
For example, they take up GABA from the extracellular space
(1) through the action of a sodium-de-pendent transporter (2), and they possess functional [GABA.sub.A] receptors that activate membrane chloride channels (3).
