Amacrine cells seem to have several different functions, many of them unknown: one type of amacrine seems to play a part in specific responses to moving objects found in retinas of frogs and rabbits; another type is interposed in the path that links ganglion cells to those bipolar cells that receive rod input.e have seen that the main features of the ganglion-cell receptive fields are to be found already in the bipolar cells. This leaves open the question of what transformations of information occur between bipolars and ganglion cells.
Antibodies in Research. Antibodies are proteins made by B cells, part of the body's immune system. The normal function of antibodies is to latch onto foreign substances (antigens) and flag them for destruction, thus helping to fight infection.ntibodies have become one of the most important tools for studying protein function in cells. To see how antibodies are used, consider the challenge of determining where actin is located in a nerve cell.
