Cerebellar cortex immunostained for glial fibrillary acidic protein (GFAP) a marker of astrocytes that are located in the granular layer. In the molecular layer, the parallel radial processes that reach the pial surface belong to Bergmann glia or Golgi epithelial cells.
DNA Helix - 3d rendered image. Genetic research concept. Complex spiral structure illustration. Medical, science, genetic biotechnology, gene cell, chromosome idea. DNA strands on dark background . Science nanotechnology.
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
