Abstract
T cells require costimulatory signals for optimal proliferation, differentiation, and survival and thus to induce protective immune responses. Recent data, however, show that during chronic lymphocyte choriomeningitis virus (LCMV) infection, triggering of the costimulatory receptor CD27 by its ligand CD70 impedes neutralizing antibody production and leads to viral persistence. Thus, while being crucial for the induction of some adaptive effector pathways, costimulation may block the development of others. Pathogens may exploit this Achilles' heal to achieve persistence.Keywords
