A Subset of CD4 + Thymocytes Selected by MHC Class I Molecules

Bendelac, Albert, Killeen, Nigel, Littman, Dan R., Schwartz, Ronald H.·1994·Science

Abstract

To complete their maturation, most immature thymocytes depend on the simultaneous engagement of their antigen receptor [αβ T cell receptor (TCR)] and their CD4 or CD8 coreceptors with major histocompatibility complex class II or I ligands, respectively. However, a normal subset of mature αβ TCR+ thymocytes did not follow these rules. These thymocytes expressed NK1.1 and a restricted set of αβ TCRs that are intrinsically class I-reactive because their positive selection was class I-dependent but CD8-independent. These cells were CD4 + and CD4 - 8 - but never CD8 + , because the presence of CD8 caused negative selection. Thus, neither CD4 nor CD8 contributes signals that direct their maturation into the CD4 + and CD4 - 8 - lineages.

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.
