A role for antigen in the maintenance of immunological memory

David Gray. Nat Rev Immunol. 2002 Jan.

Abstract

The immune system has a memory that it exhibits in the enhanced and augmented responses the second time it meets an antigen. The memory is the result of a number of changes to the system brought about during the primary response. The most important of these changes is the formation of an expanded pool of antigen-specific memory cells. One of the enduring questions in immunology is how these memory cells are maintained for such long periods.
