BACKGROUND Platelet-derived microparticles (PDMP), selectins, and adiponectin play an important role in the development of atherosclerosis in diabetes. Miglitol has been shown to have a beneficial effect on postprandial hyperglycemia in diabetic patients. However, its influence on platelet activation markers (PDMP and soluble CD40 ligand [sCD40L]), selectins, and adiponectin in these patients i...

Introduction: Women with polycystic ovary syndrome (PCOS) are at increased risk of developing cardiovascular diseases. Exercise is a therapeutic strategy to improve vascular function and reduce patient mortality. Thus, this study aimed to evaluate the effect of eight weeks of high-intensity interval training (HIIT) on serum levels of VCAM-1 and E-selectins in women with PCOS. Materials and Meth...

In chronic myelogenous (CML) and chronic eosinophilic leukemia (CEL), neoplastic cells spread via the circulation into various extramedullary organs. As E- and P-selectin constitute the starting point for the leucocyte adhesion/invasion cascade, and CEL and CML cells share many properties with normal granulocytes, we investigated the role of these selectins in CEL and CML cell expansion and org...

Less than a decade ago, the cloning of three seemingly disparate vascular cell surface molecules uncovered the selectin family of receptors that are now known to mediate critical cell-cell interactions in processes such as leukocyte trafficking, thrombosis, acute and chronic inflammation, and ischemia-reperfusion injury (1–15). L-, E-, and P-selectin are type-1 membrane glycoproteins sharing a ...

Chronic contact hypersensitivity (CH) models induced by repeated hapten exposure exhibit chronic dermatitis and immunological abnormalities resembling atopic dermatitis. To assess the contribution of endothelial selectins (P- and E-selectins) to cutaneous chronic inflammation, chronic CH responses were assessed in mice lacking P- or E-selectin. Elicitation with oxazolone on the ears of P-select...

P- and E-selectin mediate CD4+ Th1 cell migration into the inflamed skin in a murine contact hypersensitivity model. In this model, not only CD4+ T cells but also CD8+ T cells infiltrate the inflamed skin, and the role of CD8+ type 1 cytotoxic T (Tc1) cells as effector cells has been demonstrated. Here we show that in mice deficient in both P- and E-selectin, the infiltration of CD8+ T cells in...

Selectin interactions with glycolipids have been examined previously under static conditions, whereas physiologic interactions mediated by selectins take place under flow. We find that under physiologic flow conditions, sialyl Lewis(x) (sLe(x)) glycolipid and sialyl Lewisa (sLe(a)) neoglycolipid support tethering and rolling adhesions of Chinese hamster ovary (CHO) cells expressing E-selectin a...

The first step of leukocyte extravasation, leukocyte rolling, is mediated by E-, P-, and L-selectins. Mice deficient for alpha-1,3-fucosyltransferase VII (FucTVII)(-/-) are characterized by deficiency of E-, P-, and L-selectin ligand activity. This model system was used to evaluate the role of the interactions of selectins with their ligands in T and B cell responses. In the present study, FucT...

New evidence confirms the multi-step model for leukocyte migration through endothelia, but with a twist. The selectins are not always required, and some lymphocyte subsets rely heavily on integrins for their migration to tissues.

Immune dysfunction has been implicated in the pathophysiology of schizophrenia. Leukocyte migration to the site of inflammation is a fundamental step of immune response which involves P-, E-, and L-selectins. Elevated selectin levels have been reported in un-medicated first-episode patients with schizophrenia but not in medicated patients with multi-episode schizophrenia. We measured fasting pl...
