Abstract

Interaction between neutrophils and other leukocytes plays a variety of important roles in regulating innate and adaptive immune responses. Recently, we have shown that neutrophils amplify NK cell/6-sulfo LacNAc+ dendritic cells (slanDC)-mediated cytokine production, by potentiating IL- 12p70 release by slanDC via CD18/ICAM-1 and directly costimulating IFNγ production by NK cells via ICAM-3. Herein, we have identified additional molecules involved in the interactions among neutrophils, NK cells and slanDC. More specifically, we provide evidence that: i) the cross-talk between neutrophils and NK cells is mediated by ICAM-3 and CD11d/CD18, respectively; ii) slanDC potentiate the production of IFNγ by NK cells via CD11a/CD18. Altogether, our studies shed more light on the role that adhesion molecules play within the neutrophil/NK cell/slanDC network. Our data also have potential implications in the pathogenesis of diseases driven by hyperactivated leukocytes, such as Sweet's syndrome, in which a neutrophil/NK cell co-localization is frequently observed.
