Persistence of Memory CD8 T Cells in MHC Class I-Deficient Mice

Murali-Krishna, Kaja, Lau, Lisa L., Sambhara, Suryaprakash, Lemonnier, Francois, Altman, John, Ahmed, Rafi·1999·Science

Abstract

An understanding of how T cell memory is maintained is crucial for the rational design of vaccines. Memory T cells were shown to persist indefinitely in major histocompatibility complex (MHC) class I–deficient mice and retained the ability to make rapid cytokine responses upon reencounter with antigen. In addition, memory CD8 T cells, unlike naı̈ve cells, divided without MHC–T cell receptor interactions. This “homeostatic” proliferation is likely to be important in maintaining memory T cell numbers in the periphery. Thus, after naı̈ve CD8 T cells differentiate into memory cells, they evolve an MHC class I–independent “life-style” and do not require further stimulation with specific or cross-reactive antigen for their maintenance.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
