摘要

Just over 20 years ago, it was reported that human cloned T cells enter a state of unre-sponsiveness when allowed to present antigen to each other1. Shortly thereafter, an analogous form of tolerance was noted in vitro and in vivo in mouse T cells exposed to antigen in the presence of 'costimulation-poor', chemically modified antigen-presenting cells2 or purified major histocompatibility complex class II molecules3. In both experimental systems, 'anergic' T cells were incapable of proliferating after rechallenge with antigen, at least in part because of their inability to produce interleukin 2 (IL-2).
