            — an important responsibility — definitely needs further consideration. It
            knows that the T cells defend the human body, identify the enemy and

            present the enemy it captures to the T cells for them to provide intelli-
            gence about it.
                 Why would the cell do this? According to the theory of evolution,
            this cell should be concerned only about its own well-being. However, it
            serves the system, although it receives no benefit from it.
                 What is even more interesting is that the APC are very well aware of

            the requirements of the T cells. Based on this, the APC will break down
            the enemy cell and present to the T cell only the amino acid sequence. This
