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. What the dendritic cell does isn't actually exit. It leaves the tissue, enters our blood system and it moves to the lymph nodes of our body. And this is the cell that calls upon our adaptive immune system as we'll see in just a moment.
