摘要:
Memory is a long-recognized, crucial and poorly understood property of adaptive immunity. Jacob and Baltimore1 have designed an elegant genetic approach to marking memory T cells and their precursors irreversibly and have obtained intriguing results1,2. I suggest that the particular enzyme (human placental alkaline phosphatase) chosen for irreversible marking in postnatal life contributes to certain features of this system and perturbs the homeostatic mechanisms of T-cell activation and death.
