Cryoprotectant-induced Redistribution of Intramembranous Particles in Mouse Lymphocytes
This study demonstrates, by freeze fracture, clustering of intramembranous particles caused by cryoprotectant treatment of intact unfixed mouse lymphoid cells. Both T and B cells react in a similar fashion, while similar clustering of particles is not observed in some other cell types. The intramembranous particles can be aggregated by incubating unfixed cells in glycerol or dimethylsulfoxide (...
متن کاملIntercellular junctions, intramembranous particles and cytoskeletal elements of deep cells of the Fundulus gastrula.
The fine structure of motile deep cells of the gastrula stage of Fundulus heteroclitus was studied with transmission electron microscopy, using both thin sectioning and freeze-cleave techniques. Gastrula deep cells form extensive non-junctiona appositions with each other, in which the apposed plasma membranes are parallel and separated by a distance of 26-28 nm. They also form gap junctions. Ti...
متن کاملRelationship of aggregated intramembranous particles to water permeability in vasopressin-treated toad urinary bladder.
It has been previously demonstrated with freeze-fracture electron microscopy that vasopressin induces specific structural alterations of the luminal membrane of granular cells from toad urinary bladder in a dose-dependent fashion. These alterations consist of aggregated intramembranous particles and are observed both in the presence and absence of an osmotic gradient. We examined the effect of ...
متن کاملRelationships between intramembranous particles and surface coat carbohydrates in cells of a compact tissue.
The structural relationships between intramembranous particles (IMPs) and surface carbohydrates have been studied in cells of a compact tissue--uterine epithelial cells--using an in vivo technique. This involves introducing small amounts of glycerol into the uterine lumen of anaesthetized rats. The treatment results in extensive aggregation of IMPs in the apical plasma membrane of the epithelia...
متن کاملLipidic metabolism in parasitic platyhelminthes
This review is an account of research into the biochemistry of lipids of platyhelminth parasites. Taking as high benchmark major metabolic pathways of vertebrates we summarize catabolic and synthesis routes now thought to be characteristic of this group. We emphasize the litlle recent information that exists on intermediary metabolism in these parasites. However, new data may be challenging old...
