Cell Biological Studies on the Surface Carbohydrate of Plant Cell.

Cell surface glycoproteins: biochemical, immunological and molecular biological studies.

This article briefly summarizes the author's contribution to the study of cell surface glycoproteins. At first, much effort was devoted to developing analytical methods, especially exoglycosidases and endoglycosidases. An endo-beta-N-acetylglucosaminidase found in Streptococcus pneumoniae was the first example of an endoglycosidase acting on glycoproteins. A combination of radioactive labeling,...

Dual Effects of Plant Antioxidants on Neuron Cell Viability

  Background : Many studies have focused on oxidative stress induced damage and hence, the protective effects conferred by antioxidants. An example is neurodegenerative diseases which is thought to occur due to neuronal loss associated with oxidative stress. However, some antioxidants such as vitamin E have been shown to also exert pro-oxidative effects at high concentration.   Objective : In t...

Cell biological studies of the prion protein.

Studying PrPC and PrPSc in cell culture systems is advantageous because such systems contain all the organelles, membranes, and molecular cofactors that are likely to play an important role in the biology of the proteins. Using cultured cells expressing PrPC, we have discovered that this isoform constitutively cycles between the cell surface and an endocytic compartment, a process that is media...
