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.
However, it also performs as a paracrine factor in a number of its physiological activities, including its important role in normal placental function ( Bajoria et al. 2002), its expression by myofibroblasts, keratinocytes, and s.c. adipocytes at sites of wound healing, where it contributes to the repair process by exerting paracrine stimulation of angiogenesis ( Murad et al. 2003), and its local production in the anterior pituitary gland where it modulates thyrotropin secretion ( Jin et al ...
