Abstract
Eosinophil recruitment is a pathological hallmark of many allergic and helminthic diseases. Here, we investigated chemokine receptor CCR3-induced eosinophil recruitment in sialyltransferase St3gal4-/- mice. We found a marked decrease in eosinophil extravasation into CCL11-stimulated cremaster muscles and into the inflamed peritoneal cavity of St3gal4-/- mice. Ex vivo flow chamber assays uncovered reduced adhesion of St3gal4-/- compared to wild type eosinophils. Using flow cytometry, we show reduced binding of CCL11 to St3gal4-/- eosinophils. Further, we noted reduced binding of CCL11 to its chemokine receptor CCR3 isolated from St3gal4-/- eosinophils. This was accompanied by almost absent CCR3 internalization of CCL11-stimulated St3gal4-/- eosinophils. Applying an ovalbumin-induced allergic airway disease model, we found a dramatic reduction in eosinophil numbers in bronchoalveolar lavage fluid following intratracheal challenge with ovalbumin in St3gal4-deficient mice. Finally, we also investigated tissue-resident eosinophils under homeostatic conditions and found reduced resident eosinophil numbers in the thymus and adipose tissue in the absence of ST3Gal-IV. Taken together, our results demonstrate an important role of ST3Gal-IV in CCR3-induced eosinophil recruitment in vivo rendering this enzyme an attractive target in reducing unwanted eosinophil infiltration in various disorders including allergic diseases.

Abstract
Abstract
Eotaxin is a potent eosinophil chemoattractant that plays an important role in regulating eosinophil tissue levels both in healthy individuals and in diseases associated with significant eosinophil infiltrates, such as the allergic inflammation observed in asthma. Here, we demonstrate that treatment of eosinophils with eotaxin induces the phosphorylation of the mitogen-activated protein kinases (MAPKs) p42 and p44, leading to kinase activation. Blockade of MAPK activation by the MAPK kinase inhibitor PD98059 leads to a dramatic decrease in eotaxin-induced eosinophil rolling in vivo and chemotaxis in vitro. This blockade in the leukocyte migration process is consistent with the observed inhibition of actin polymerization and rearrangement within the eosinophil following treatment with MAPK inhibitor. It is suggested, therefore, that the intrinsic mechanism of eotaxin-induced eosinophil rolling and migration involves activation of the p42/p44 MAPK, possibly through regulation of the cytoskeletal rearrangements necessary for chemotaxis.

Abstract
Abstract
The multistep model of leukocyte adhesion reveals that selectins mediate rolling interactions and that integrins mediate firm adhesion processes. In this study, the interaction between eosinophils and TNF-α-activated HUVEC (second or third passage) was studied under flow conditions (0.8 and 3.2 dynes/cm2). Especially the role of α4 integrins on eosinophils and E-selectin on HUVEC was studied. Inhibition of the integrin α4 chain on eosinophils reduced the number of firmly adhered resting eosinophils to TNF-α-stimulated endothelium by 43% whereas the percentage rolling cells increased 2.2-fold compared with untreated control eosinophils. Blocking of E-selectin on the endothelium reduced the number of adherent eosinophils by only 23% and 16%. In this situation, however, hardly any rolling adhesion was observed, and the few rolling cells showed a low rolling velocity. Blocking both α4 integrin on eosinophils and E-selectin on HUVEC reduced the number of adhered eosinophils by 95%. P-selectin did not significantly participate in eosinophil adhesion to TNF-α-activated HUVEC. Inhibition of both α4 integrins and β2 integrins on eosinophils resulted in a reduction of adhered cells by 65% and a 3-fold increase in percentage rolling cells. Taken together, these results clearly show that resting eosinophils preferentially use constitutively active α4 integrins (α4β1, α4β7) for the first attachment to TNF-α-activated HUVEC. In addition, α4 integrins and E-selectin work synergistically in eosinophil adherence to TNF-α-activated HUVEC. Although E-selectin is important for eosinophil rolling under these conditions, P-selectin plays only a minor role.

Abstract
Abstract
The comparative ability of the complement anaphylatoxins C3a and C5a to mediate leukocyte adhesion and transendothelial migration in vivo and in vitro was investigated. Superfusion of IL-1β-stimulated rabbit mesentery with C3a resulted in a rapid and stable adhesion of rolling eosinophils, but not neutrophils, to postcapillary venules. However, C3a failed to evoke subsequent transmigration of the adherent eosinophils. In contrast, C5a induced both the rapid activation-dependent firm adhesion and transmigration of eosinophils and neutrophils through venular endothelium. C3a induced selective shedding of L-selectin and an increase in αMβ2 integrin expression on eosinophils but not neutrophils, while C5a induced shedding of L-selectin and up-regulation of αMβ2 integrin on both eosinophils and neutrophils. Both C3a- and C5a-dependent adhesion to venular endothelium was blocked by ex vivo treatment of eosinophils with anti-α4 and anti-β2 integrin mAbs. In vitro, both C3a (but not C3adesArg) and C5a (including C5adesArg)-dependent transmigration of eosinophils across IL-1β-stimulated endothelial monolayer was mediated by α4β1 and αMβ2 integrins. Overall these studies suggest that C3a is eosinophil-specific chemotactic mediator that influences selectively eosinophil adhesion but not transmigration in vivo. C5a in contrast is a complete activator of integrin-dependent adhesion as well as transmigration of eosinophils and neutrophils.

Abstract
Abstract
Infection of endothelial cells by Listeria monocytogenes is an essential step in the pathogenesis of listeriosis. We recently reported that L. monocytogenes induces up-regulation of E-selectin and other endothelial adhesion molecules and subsequent polymorphonuclear leukocyte (PMN) adhesion into cultured human endothelial cells. In the present study, we characterized the mechanisms of enhanced E-selectin expression using L. monocytogenes wild type (EGD), the isogenic in-frame deletion mutants for phosphatidylcholine (PC)- and phosphatidylinositol (PI)-specific phospholipases EGDΔplcA and EGDΔplcB, as well as the nonvirulent control strain Listeria innocua. Infection of endothelial cells with EGDΔplcA or EGDΔplcB for 6 h induced, as compared with EGD wild type, intermediate levels of E-selectin mRNA and protein as well as PMN rolling and adhesion at a shear rate of 1 dyne/cm2, indicating that both bacterial phospholipases are required for a maximal effect. Similarly, ceramide content and NF-κB activity were increased in L. monocytogenes-exposed endothelial cells, but only to intermediate levels for PC- or PI-phospholipase C (PLC)-deficient listerial mutants. Phospholipase effects could be mimicked by exogenously added ceramides or bacterial sphingomyelinase. The data presented indicate that PI-PLC and PC-PLC are important virulence factors for L. monocytogenes infections that induce accumulation of ceramides that in turn may act as second messengers to control host cell signal-transduction pathways leading to persistent NF-κB activation, increased E-selectin expression, and enhanced PMN rolling/adhesion. The ability of L. monocytogenes to stimulate PMN adhesion to endothelial cells may be an important mechanism in the pathogenesis of severe listeriosis.

Abstract
Abstract
The role of endothelial selectins in mediating eosinophil recruitment was assessed using the trafficking of 111In-labeled blood eosinophils in mouse skin. An intradermal injection of chemoattractants (leukotriene B4, macrophage inflammatory protein-1α, and eotaxin) resulted in a rapid accumulation of 111In eosinophils that was reduced 49 to 91% by anti-P-selectin mAb. An anti-E-selectin mAb was ineffective, although a combined E- and P-selectin blockade resulted in >95% inhibition of all responses. The accumulation of a pulse of 111In eosinophils at sites of active cutaneous anaphylaxis (ACA) at 4 to 8 h and at 20 to 24 h after Ag challenge was completely dependent upon E- and P-selectin in combination, but not in isolation. In contrast, at 20 to 24 h after Ag challenge in a delayed-type hypersensitivity (DTH) reaction in skin, 111In eosinophil accumulation was largely independent of endothelial selectins, even when L-selectin was also blocked. An anti-α4 integrin mAb significantly reduced 111In eosinophil trafficking in both allergic reactions but was slightly more effective in the DTH reaction compared with the ACA reaction. These results show that P-selectin and to a lesser extent E-selectin mediate eosinophil recruitment in skin in acute inflammatory reactions. In allergic, late-onset inflammatory reactions, neither P- nor E-selectin alone are sufficient to mediate eosinophil accumulation; when combined, they are essential for trafficking in ACA but are less important in the DTH reaction. Whether α4 integrin-based strategies will be more effective than selectin-based strategies at inhibiting eosinophil recruitment in human disease remains to be determined.

Abstract
Abstract
E- and P-selectin are cell surface lectins that mediate leukocyte-endothelial cell adhesion and thereby participate in neutrophil recruitment into inflammatory sites. E-selectin can be induced on endothelial cells by various activators, including TNF-α, IL-1β, and PMA. Induction of E-selectin is blocked by pretreatment of endothelial cells with IL-4 or TGF-β, both of which have antiinflammatory properties in vivo. In addition to its well-known proinflammatory activities, IFN-γ also has antiinflammatory effects in vivo, one of which is inhibition of neutrophil recruitment. To determine whether IFN-γ inhibits neutrophil recruitment by inhibiting adhesion molecule expression, the effect of IFN-γ on activation-induced cell adhesion molecule expression by cultured HUVEC was evaluated. Pretreatment of endothelial cells with IFN-γ for 24 to 72 h before 6- to 24-h activation with IL-1β, TNF-α, or PMA resulted in significantly reduced levels of cell surface E-selectin, although levels of ICAM-1 and VCAM-1 were the same or increased. The reduction of cell surface E-selectin levels under these conditions was reflected in reduced levels of E-selectin mRNA, indicating an effect at the transcription level or RNA stability. Interestingly, the increase of cell surface P-selectin expression due to IL-4 treatment of HUVEC was also inhibited by IFN-γ, while constitutive levels of P-selectin were not. These results suggest that the inhibition of neutrophil recruitment by IFN-γ in vivo may be due, in part, to the ability of IFN-γ to inhibit E- and P-selectin up-regulation. Furthermore, these findings emphasize the process of leukocyte recruitment as an important step through which IFN-γ can direct the character of inflammatory reactions.
