Abstract
Objective
To elucidate the relationship between leukocyte-associated Ig-like receptor-1 (LAIR-1) and the pathogenesis of Kawasaki disease (KD) and coronary artery aneurysms(CAA).
Methods
The study cohort comprises children who were diagnosed with KD and were categorized into two groups: KD patients with CAA (KD-CAA) and KD without CAA (KD-NCAA), with healthy children serving as control group (HC). LAIR-1 on leukocytes was examined via flow cytometry, while serum LAIR-1 (sLAIR-1) was quantified using ELISA. IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17A, IFN-α, IFN-γ and TNF-α were examined by Immunofluorescence assay.
Results
sLAIR-1 levels were elevated in the KD and KD-CAA groups compared with those in the HC and KD-NCAA groups (P < 0.05). sLAIR-1 exhibited an area under the curve value of 0.858 for predicting KD (P < 0.001) and 0.628 for predicting CAA (P = 0.055, borderline significance). LAIR-1 was increased on the neutrophils in KD group, whereas it was lower in KD-CAA than that in KD-NCAA, and decreased in KD after IVIG treatment. In contrast, LAIR-1 was reduced on CD4+ and CD8+ T lymphocyte in KD group, and increased in KD after IVIG treatment (all P < 0.05). LAIR-1 on neutrophils showed a positive correlation with IL-5, while on CD4+ T cells, it was negatively correlated with IL-2, IL-6, IL-10, IFN-γ, and IL-8. On CD8+ T cells, LAIR-1 was negatively correlated with IL-2 and IFN-γ.
Conclusion
sLAIR-1 may serve as a potential biomarker for KD and CAAs, while LAIR-1 might be implicated in KD pathogenesis and CAA.
期刊介绍:
Immunology Letters provides a vehicle for the speedy publication of experimental papers, (mini)Reviews and Letters to the Editor addressing all aspects of molecular and cellular immunology. The essential criteria for publication will be clarity, experimental soundness and novelty. Results contradictory to current accepted thinking or ideas divergent from actual dogmas will be considered for publication provided that they are based on solid experimental findings.
Preference will be given to papers of immediate importance to other investigators, either by their experimental data, new ideas or new methodology. Scientific correspondence to the Editor-in-Chief related to the published papers may also be accepted provided that they are short and scientifically relevant to the papers mentioned, in order to provide a continuing forum for discussion.
