What is immunological surveillance mechanism?
c | Tertiary immune surveillance represents a mechanism by which the immune system can hedge its bets, providing enhanced adaptive immune responses to antigens encountered in tissues distinct from those in which they were previously encountered.

Which cell type is involved in immune surveillance?
These include antigen non-specific leukocytes, such as neutrophils and natural killer cells, as well as key components of the adaptive immune system, such as effector T cells (Fig. 3).
