Abstract
We describe a novel antigen recognized by mAb 2E3 selectively expressed in the periphery by a subset of porcine CD4+ T cells. Both, CD4+CD8alpha- and CD4+CD8alphalow T cell subpopulations express this antigen. CD4+2E3+ T cells show phenotypical and functional characteristics of nai;ve cells. The majority of them are CD29low, CD45RAhigh, CD49dlow, CD11alow, CD18low, and SLA-II-. After mitogen activation CD4+2E3+ T cells express high levels of IL-2 mRNA, but only traces of IFN-gamma or IL-4 mRNA. Indeed a minor percentage of cells stained positive for IFN-gamma when assessed by flow cytometry. Moreover, CD4+2E3+ T cells did not proliferate in response to the recall antigen lysozyme, although they did efficiently to the mitogen ConA. By contrast, CD4+2E3- T cells show phenotypical and functional characteristics of primed cells. They express markers associated to a memory phenotype, respond to the recall antigen lysozyme, and produce high amounts of IFN-gamma and IL-4.

Abstract
Abstract
P-selectin plays an important role in leukocyte adherence to microvascular endothelium and is expressed in synovial tissue from patients with rheumatoid arthritis (RA). However, the contribution of P-selectin to the initiation and chronicity of joint inflammation is not well understood. In these studies, collagen-induced arthritis (CIA) was induced in P-selectin mutant (−/−) mice to explore the role of P-selectin in the development of joint inflammation. Surprisingly, CIA onset was accelerated and severity was increased in P-selectin mutant mice, compared with wild-type mice (+/+). Increased levels of anti-type II collagen IgG were detected in both nonarthritic and arthritic P-selectin mutant mice from days 14–91. In addition, splenocytes isolated from immunized and nonimmunized P-selectin mutant mice produced significantly less IL-2 and IL-4, but significantly higher levels of IL-10 and IL-5 than splenocytes from wild-type mice. These observations show that P-selectin-mediated leukocyte rolling is not required for the development of murine CIA and that P-selectin expression exerts a controlling effect on the development of Ag-driven inflammatory joint disease, possibly by mediating the recruitment and/or trafficking of specific leukocyte subtypes into lymphoid tissue or inflammatory foci.

Abstract
Abstract
Selective recruitment of eosinophils to sites of allergic and parasitic inflammation involves specific adhesion and activation signals expressed on or presented by stimulated endothelial cells. Here we examined leukocyte recruitment on cytokine-activated HUVEC under flow conditions. We perfused whole blood through a flow chamber to examine mechanisms of selective leukocyte recruitment. Although there was substantial recruitment of leukocytes on TNF-α-stimulated HUVEC, we found no selective accumulation of any particular leukocyte subpopulations. In contrast, fewer leukocytes were recruited to IL-4-stimulated HUVEC, but the recruitment was selective for eosinophils. We examined the role of adhesion molecules in these interactions and found that eosinophil recruitment was completely blocked with an α4 integrin mAb at the shear rates examined. A significant number of neutrophils were also recruited to IL-4-stimulated HUVEC, and these interactions required P-selectin and P-selectin glycoprotein ligand-1. Thus, whole blood perfusion over cytokine-activated endothelium revealed that IL-4-stimulated HUVEC support selective recruitment of eosinophils, whereas TNF-α-stimulated HUVEC lack selectivity for any leukocyte subclass.

Abstract
Abstract
Immune responses may be qualitatively distinct depending on whether Th1 or Th2 cells predominate at the site of Ag exposure. T cell subset-specific expression of ligands for vascular selectins may underlie the distinct patterns of recruitment of Th1 or Th2 cells to peripheral inflammatory sites. Here we examine the regulation of selectin ligand expression during murine T helper cell differentiation. Large numbers of Th1 cells interacted with E- and P-selectin under defined flow conditions, while few Th2 and no naive T cells interacted. Th1 cells also expressed more fucosyltransferase VII mRNA than naive or Th2 cells. IL-12 induced expression of P-selectin ligands on Ag-activated naive T cells, even in the presence of IL-4, and on established Th2 cells restimulated in the presence of IL-12 and IFN-γ. In contrast, Ag stimulation alone induced only E-selectin ligand. Interestingly, restimulation of established Th2 cells in the presence of IL-12 and IFN-γ induced expression of P-selectin ligands but not E-selectin ligands; IFN-γ alone did not enhance expression of either selectin ligand. In summary, functional P- and E-selectin ligands are expressed on most Th1 cells, few Th2 cells, but not naive T cells. Furthermore, selectin ligand expression is regulated by the cytokine milieu during T cell differentiation. IL-12 induces P-selectin ligand, while IL-4 plays a dominant role in down-regulating E-selectin ligand.

Abstract
Abstract
In this study, an in vitro flow model and a blocking mAb to P-selectin glycoprotein ligand-1 (PSGL-1) were used to define the role of PSGL-1 in monocyte attachment and rolling on E- and P-selectin and in attachment and accumulation on 6-h TNF-α-activated HUVEC. KPL1, an adhesion-blocking mAb directed against the tyrosine sulfate motif of PSGL-1, abolished monocyte-adhesive interactions with P-selectin, but only partially blocked monocyte interaction with E-selectin. Further analysis showed that on E-selectin, KPL1 blocked only secondary (i.e., monocyte/monocyte) interactions, but did not block primary (i.e., monocyte/E-selectin) interactions, with secondary adhesion accounting for 90% of the total adhesive interactions on either E- or P-selectin. On cytokine-activated HUVEC, monocytes initially attached and formed linear strings of adherent cells, which involved both primary and secondary adhesion. PSGL-1 or L-selectin mAb reduced string formation, and the combination of PSGL-1 and L-selectin mAb prevented monocyte strings and inhibited 86% of accumulation. Monocyte attachment and rolling on purified adherent monocytes were also critically dependent on PSGL-1 on the adherent monocytes. These studies document that secondary interactions between monocytes, mediated by PSGL-1, are crucial for monocyte initial attachment, rolling, and accumulation on activated endothelium under laminar shear flow.

Abstract
Abstract
This study examined the adhesive interactions of peripheral blood NK cells with P- and E-selectin and analyzed the effect of IL-12 on the binding of NK cells to these selectins. P-selectin glycoprotein ligand-1 (PSGL-1) is expressed on most resting and IL-12-activated NK cells. However, the percentage of resting NK cells bound to P-selectin-IgG was 15%, and that of activated NK cells bound to P-selectin-IgG was 65%. Furthermore, the number of IL-12-activated NK cells bound to P-selectin-transfected Chinese hamster ovary cells was significantly higher than that of resting NK cells under flow conditions. These interactions were abolished by the incubation of these NK cells with anti-PSGL-1 (PL-1) mAb. Thus, PSGL-1/P-selectin interaction is important in the binding of resting and activated NK cells to P-selectin. NK cells express sialyl-Lewisx (sLex) structure recognized by anti-sLex mAb (KM-93), and IL-12 activation of NK cells increased the mean fluorescence intensity of KM-93-reactive NK cells. Adhesion of IL-12-activated NK cells to E-selectin-transfected Chinese hamster ovary cells was stronger than that of resting NK cells under flow conditions. These interactions were reduced markedly by incubation with anti-sLex mAb. Thus, sLex is the major ligand of resting and activated NK cells for E-selectin. These findings indicate that IL-12 stimulation of NK cells promotes their adhesion activity to endothelial selectins.

Abstract
Abstract
Lymphocyte binding to high endothelial venules (HEV) in noninflamed peripheral lymph nodes (PLN) relies heavily on two endothelial adhesion molecules called vascular adhesion protein-1 (VAP-1) defined by mAb 1B2 and the peripheral lymph node addressins (PNAd) defined by mAb MECA-79. Data from several different groups indicate that these two molecules share several characteristics in expression, biochemical structure, and function, raising the possibility that VAP-1 may be identical to the 170- and 90-kDa species of PNAd glycoproteins. In this study, we show that many PLN HEV coexpress these two molecules. In parallel SDS-PAGE analyses, the m.w. of the 90- and 170-kDa forms of these molecules are indistinguishable. Nevertheless, we show by different metabolic labelings, by reciprocal cross-precipitations, and by immunofluorescence stainings of newly established VAP-1 transfectants that the 90- and 170-kDa species of PNAd and VAP-1 are distinct molecules. In functional terms, VAP-1 is strikingly selective in mediating PLN HEV adhesion of CD8-positive, but not of CD4-positive T cells. In contrast, PNAd contributes to the adhesion of both CD4-positive and CD8-positive cells to these vessels. Together, these data show that initial adhesion of CD8-positive lymphocytes to PLN HEV requires a PNAd- and a VAP-1-dependent step that are both essential and may occur simultaneously or sequentially.

Abstract
Abstract
Immunity to genital tract infection with Chlamydia trachomatis is mediated by type 1 CD4+ T lymphocytes. To define the signals that govern lymphocyte trafficking to the genital mucosa, integrins expressed by infiltrating T cells and endothelial addressins displayed on local vasculature were characterized during the course of infection. All T cells expressed the αLβ2 heterodimer that binds vascular ICAM-1, and most displayed enhanced levels of the α4β1 integrin that interacts with VCAM-1. αE and β7low integrin chains were detected on approximately 15 and 30% of infiltrating T cells, respectively. Lymphocytes derived from the spleen or draining lymph nodes expressed this same integrin profile, suggesting that cells are recruited to the genital mucosa from the systemic circulation without significant selection pressure for these markers. Immunofluorescent staining for the corresponding vascular addressins revealed intense expression of VCAM-1 on small vessels within Chlamydia-infected genital tracts and up-regulation of ICAM-1 on endothelial, stromal, and epithelial cells. Mucosal addressin cell adhesion molecule-1 was not detected within genital tissues. These results indicate that T lymphocyte homing to the genital mucosa requires the interaction of αLβ2 and α4β1 with endothelial ICAM-1 and VCAM-1, respectively, which is the same pathway that directs lymphocytes to systemic sites of inflammation. Homing pathways defined for the intestinal mucosa and assumed to be relevant to all mucosal sites are not well represented in the genital tract. The identification of T lymphocyte trafficking pathways shared between systemic and mucosal tissues should facilitate vaccine strategies aimed at maximizing immune responses against Chlamydia and other pathogens of the urogenital tract.
