Now these also release cytokines and the cytokines essentially call upon other cells. For example macrophages, neutrophils and other cells as we'll discuss in just a moment. Now let's move on to this other cell found within a tissue known as aridandritic cell. Now dendritic cells are also capable of taking these antigens but they engulf those antigens into that cell. Inside the cell they can digest or break down those antigens into smaller antigens and they take a small portion of the antigen known as an epitope and they place it on a special membrane known as the major historicompatibility complex that is found on that membrane. So once these antigens showed in red are on the membrane protein.
