Memory is a key feature of the central nervous system that enables an organism to adapt and respond appropriately to a stimulus-rich environment. In the same way, the ability of the adaptive immune system to 'remember' past encounters with pathogens allows the host to survive in an antigenically hostile environment. This month's focus features a series of specially commissioned reviews of the cellular and molecular bases of immunological memory (http://www.nature.com/ni/focus/immunologicalmemory/).

    Naive lymphocytes have a finite lifespan and are continually replaced by input from generative organs. In contrast, memory cells or their progeny can last a lifetime. The expanded populations of memory cells and their more widespread distribution provide protection against recurrent infection.
