Ontogeny State of the Art Reportieving the appropriate numbers of different types of glial cells and their correct proportion to neurons, the deployment of glia and neurons to their proper destinations in the central (CNS) and peripheral nervous systems (PNS), the induction of glial process outgrowth, axonal ensheathment, and theseparate 发表于 2025-3-28 22:28:32
Cellular and Non-Cellular Influences on Myelin-Forming Cellsation are unknown. In many experimental demyelinating conditions of the central nervous system substantial remyelination by oligodendrocytes is observed, in others Schwann cells may provide myelin of the peripheral type within central neural tissues. The precise environmental requirements for the pr昆虫 发表于 2025-3-29 00:10:31
Cell Interactions and the Cytoskeletonperformed by a transmembrane connection, linking the cell surface and the cytoskeleton. The structural and molecular bases for that connection are not known. Recent studies of the cytoskeleton itself, concentrating on in situ analysis, have provided new approaches to this problem. They have alteredesoteric 发表于 2025-3-29 04:00:27
Signalling Between Neuronal and Glial Cellsa. Many possible mechanisms exist for the transfer of information between the two cell types which are separated only by narrow, 200Å wide, extracellular clefts. There is increasing evidence that several of these are used. These include: 1) Activity in one cell varies the ionic composition of the ex延期 发表于 2025-3-29 08:52:57

Distribution and Functional Significance of Sodium and Potassium Channels in Normal and Acutely Demyast, there are few if any potassium channels. However, experiments in which the myelin is acutely removed show that the internodal axonal membrane, which lacks sodium channels, is rich in potassium channels. This complementary distribution may, it is speculated, be related to the fact that the functemulsify 发表于 2025-3-30 01:51:57
t mechanisme van antimicrobiële activiteit kent grote verschillen. Zo komen antibacteriële speekseleiwitten voor die alleen een bacterieaggregerende functie hebben, bijvoorbeeld mucinen, agglutinine en prolinerijk glycoproteïne (PRG). Andere eiwitten remmen microbiële enzymsystemen, bijvoorbeeld cys纠缠 发表于 2025-3-30 04:36:59
T. A. SearsG-2) mucine. MUC5. is afkomstig uit alle (sero)muceuze speekselklieren. MUC7 lijkt niet in alle personen aanwezig te zijn in palatinaal speeksel. Beide soorten mucinen verschillen in biochemische eigenschappen en hebben waarschijnlijk verschillende functies..MUC5. is verantwoordelijk voor de visco-e
