ABSTRACT

A feature of the adaptive immune response is its ability to “remember” its encounters with antigens to achieve a faster response when the same antigen is confronted at a later time. However, the mechanisms involved in this behavior are not fully understood. Th ere are several theories in the literature about how this behavior is achieved (Burnet, 1959; Celada and Seiden, 1996; Matzinger, 2002; Oprea and Perelson, 1997; Varela and Stewart, 1990).
