Amacrine Cells. Amacrine cells are interneurons found in the retina [1]. They are part of the inner plexiform layer, a section of the retina in which bipolar neurons communicate with amacrine cells and ganglion cells [2].Amacrine cells serve to integrate for ganglion cells the signals coming from bipolar neurons [1].verview. Amacrine cells perform where the second synaptic retianl layer where ganglion cells and bipolar cells form a synapse. There are close to 50 types of amacrine cells, many of which do not have axons.An amacrine cell is a horizontal cell and it works laterally to interact with the output of the bipolar cell.
The macrophage is just one cell type that may present antigens in the MHCII complex; other cells, including B cells and dendritic cells, may also act as antigen-presenting cells (APC). Only a few helper T cells in the immune system will recognize the specific antigen presented by the APC.One helper T cell must become thousands of T cells to mount the immune response against the foreign invader. The animation illustrates the passage of signals through the cell that results in T-cell proliferation.he macrophage is just one cell type that may present antigens in the MHCII complex; other cells, including B cells and dendritic cells, may also act as antigen-presenting cells (APC).
