Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by loss of tolerance toward self-nucleic acids, autoantibody production, interferon expression and signaling, defect in the regulatory T (T reg ) cell compartment. In this work, we identified that platelets from patients with active SLE preferentially interacted cells via P-selectin/P-selectin glycoprotein ligand-...

Two mechanisms have been proposed for regulating rolling velocities on selectins. These are (a) the intrinsic kinetics of bond dissociation, and (b) the reactive compliance, i.e., the susceptibility of the bond dissociation reaction to applied force. To determine which of these mechanisms explains the 7.5-11.5-fold faster rolling of leukocytes on L-selectin than on E- and P-selectins, we have c...

Both P-selectin glycoprotein ligand-1 (PSGL-1) and L-selectin are localized on the microvilli of neutrophils and have been implicated in the attachment of neutrophils to P-selectin or E-selectin. We directly compared the attachment and rolling of neutrophils on P-selectin and E-selectin under flow, with emphasis on the functions of PSGL-1 and L-selectin. Flowing neutrophils attached more avidly...

Abstract Background Myeloid cells express microparticles that could increase the expression of adhesion molecules including P-selectin. We aimed to evaluate level soluble P-selectin (sP-selectin) and prothrombin fragment 1 + 2 (F1 2), determine correlation sP-selectin with leukocyte count F1 levels in acute myeloid leukemia (AML) chronic (CML) patients. Methods Patients newly diagnosed AML ( n ...

Introduction: Psoriasis is an inflammatory skin disease in which abnormal individual immune reactivity plays an important role. Eselectin and P-selectin are adhesion molecules expressed on vascular endothelial cells in several inflammatory skin diseases, including psoriasis. The aim of the present study was to describe selected immunological changes, concerning adhesion molecules status (sEsele...
