Increased circulating levels of CD14+HLA-DRneg/low monocytes in patients with AMI.

Time course analysis of subset-frequencies and circulating levels of monocytes in patients with unstable angina (UA; n=11), non-ST-elevation MI (NSTEMI, n=16), and ST-elevation MI (STEMI, n=44).

Monocyte subset-frequencies.

CD14+HLA-DRneg/low monocytes from patients with AMI are not immunosuppressive but exhibit an inflammatory phenotype.

Expression of genes dysregulated in circulating monocytes and infarct macrophages in a mouse model of reperfused AMI.

Circulating normal-density CD10neg neutrophils increase in patients with AMI.

Increased frequency of CD10negneutrophils in patients with AMI.

Immature CD10neg neutrophils from patients with AMI express high amounts of MMP-9 and S100A9 and display resistance to apoptosis.

Expression of genes regulated in circulating neutrophils and infarct neutrophils in a mouse model of reperfused AMI.

Immature CD101neg neutrophils are rapidly released into the bloodstream after reperfusion in a mouse model of AMI.

Interactions between CD10negneutrophils and CD14+HLA-DRneg/lowmonocytes.

Multiple intercorrelations among CD10neg neutrophils, HLA-DRneg/low monocytes and immune-inflammation markers.

Immature CD101neg neutrophils are rapidly recruited to ischemic sites, are a major source of MMP-9 and IL-1ß in the reperfused myocardium and exhibit resistance to apoptosis.

Immature CD101neg neutrophils are present in mediastinal lymph nodes draining the heart after acute MI.

Elevated IFN-γ levels in patients with expanded CD10neg neutrophils and increased frequency of CD4+CD28null T-cells.

Relationship among the peripheral expansion of immature CD10neg neutrophils, CMV IgG titers, CD4+CD28null T-cells, and circulating levels of IFN-γ and IL-12 in patients with AMI.

CD10neg neutrophils enhance IFN-γ production by CD4+ T-cells via induction of interleukin-12.

IFN-γ production by CD4+ T-cells from CMV-seropositive AMI patients stimulated with anti-CD3/CD28 beads and cultured for 24 hr in absence (CD4+) or presence of cell-free supernatants derived from CD10pos neutrophils (csf-CD10pos+CD4+) or CD10neg neutrophils (csf-CD10neg+CD4+).

Immature CD10neg neutrophils and HLA-DRneg/low monocytes inducing proinflammatory and adaptive immune responses emerge in patients with large acute myocardial infarction.

General traits.

Leukocyte count and monocyte subsets.

Immune inflammation markers.
