Electron-microscopic examination of rat or ferritin conjugated to nonspecific rabbit reticulocytes and normoblasts incubated lgG. These observations support the conwith transferrin conjugated to ferritin or cept that transferrin binds to a surface ferritin-labeled antitransferrin revealed membrane receptor and is subsequently binding of ferritin conjugates to the surinternalized by the developi...

Methyl parathion induced alterations in the level of monoamines, viz. norepinephrine, dopamine and serotonin were studied in discrete regions of developing central nervous system of rat pups. A significant decrease in the level of monoamines noticed in methyl parathion toxicosis may be related to the altered neuronal activity and inefficiency, leading to depression and impairment in various beh...

The class VI intermediate filament protein nestin has been generally considered as a specific marker for neural precursor cells or developing muscles. In the prenatal developing rat central nervous system (CNS), we localized immunoreactivity for the nestin in blood vessels. Although the widespread nestin expression in cerebral blood vessels persisted in early postnatal periods, it was down-regu...

Electron-microscopic examination of rat reticulocytes and normoblasts incubated with transferrin conjugated to ferritin or ferritin-labeled antitransferrin revealed binding of ferritin conjugates to the surface membrane, and uptake of ferritin conjugates in micropinocytotic vesicles. No binding or endocytosis of ferritin was visualized when rat reticulocytes or normoblasts were incubated with f...
