Membranes are an important signalling platform in plants. The plasma membrane is the point where information about the external environment must be converted into intracellular signals, while endomembranes are important sites of protein trafficking, organization, compartmentalization, and intracellular signalling. This requires co-ordinating the spatial distribution of proteins, their activatio...

To investigate how dopamine influences the subcellular localization of the dopamine receptors in the striatal dopaminoceptive neurons, we have used immunohistochemistry to detect D1 dopamine receptors (D1R) after modifications of the dopamine environment. In normal rats, D1R are located mostly extrasynaptically at the plasma membrane of the cell bodies, dendrites, and spines. The intrastriatal ...

Modification caused in cellophane matrix (a highly hydrophilic natural polymer) by -irradiation was studied by determining changes in different electrochemical parameters obtained from measurements carried out with the membranes in contact with NaCl and MgCl2 solutions. Three different irradiation doses (10 Gy, 30 Gy and 80 Gy) were used in order to consider its possible effect in membrane modi...
