Electron Microscope Observations on Tingible Body Macrophages in Mouse Spleen
It is generally accepted that the tingible bodies (Körper) of Flemming (7) found in lymphatic tissue germinal centers represent phagocytized nuclear debris of small lymphocytes (1, 2, 6, 7, 11, and others) or both lymphocyte and erythrocyte debris (15) . Several ideas about the significance of tingible bodies assume that they are small lymphocytes . The "graveyard theory" emphasizes the phagocy...
متن کاملConcanavalin A (ConA) isolated from jack bean (Can-
avalia ensiformis) belongs to the legume lectin family. Among the monosaccharides, methyl a-D-mannopyranoside (Me a-Man, see Chart) exhibits the most potent inhibitory effect on formation of the complex of ConA with dextran, and the mannotriose 3,6-di-O-(a-D-mannosyl)-a-D-mannoside was found to be the most potent oligosaccharide, being more potent than Me a-Man. Shinohara et al. examined the bi...
متن کاملEffects of Concanavalin a on Mouse Peritoneal Macrophages
Concanavalin A (Con A) binds to saccharide residues on the mouse peritoneal macrophage plasma membrane and stimulates extensive pinocytic interiorization of the membrane. The overall pinocytic rate is increased 3.5-4.5 times by the addition of Con A, and the surface marker enzyme adenosine triphosphatase can be identified histochemically in association with the cytoplasmic vesicles generated af...
متن کاملThe Macromolecular Paracrystalline Lattice of Insect Viral Polyhedral Bodies Demonstrated in Ultrathin Sections Examined in the Electron Microscope
Thin sections of polyhedra obtained from gipsy moth larvae infected with P. dispar virus and from silkworm larvae infected with B. mori virus revealed viral particles contained within a pseudohexagonal, macromolecular, paracrystalline lattice. The gipsy moth virus occurs in bundles of one to eight rods enclosed by a limiting membrane. The particles of the silkworm virus, although generally occu...
متن کاملIsotope analysis in the transmission electron microscope
The Ångström-sized probe of the scanning transmission electron microscope can visualize and collect spectra from single atoms. This can unambiguously resolve the chemical structure of materials, but not their isotopic composition. Here we differentiate between two isotopes of the same element by quantifying how likely the energetic imaging electrons are to eject atoms. First, we measure the dis...
