Abstract

The inflammatory infiltrate in atherosclerotic plaque is composed of T cells and macrophages. CD4 + T cells with a unique phenotype, CD4 + CD28 null , are preferentially recruited into culprit lesions. These T cells are distinct from classic CD4 + CD28 + T cells in gene expression and function, including their ability to mediate cytolysis. In this study, we have investigated the regulation of CD4 + CD28 null T-cell cytolytic function. In patients with acute coronary syndromes (ACS), CD4 + CD28 null T cells express killer immunoglobulin-like receptors (KIRs). KIRs encompass a polymorphic family of receptors that recognize HLA class I molecules and have been implicated in self-tolerance. CD4 + CD28 null T-cell clones from patients with ACS and age-matched controls were compared for their KIR-expression profile. T-cell clones derived from the patients expressed a broader spectrum of KIRs ( P <0.001) with preference for the stimulatory variant, CD158j. Additionally, CD4 + T-cell clones from patients but not those from controls acquired de novo expression of the DAP12 molecule, an adapter chain that transmits CD158j-derived signals. Cumulative expression of CD158j and DAP12 endowed cytolytic competence on CD4 + CD28 null T cells, allowing them to kill in the absence of T-cell receptor triggering. Our data demonstrate that CD4 + CD28 null T cells in ACS are characterized by a unique gene expression profile. Consequently, these T cells acquire cytolytic capability that can bypass the need for T-cell receptor triggering and, thus, impose a threat to self-tolerance.

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.
