hrombospondin (TSP)-1 has been reported to modulate T cell behavior both positively and negatively. We found that these opposing responses arise from interactions of TSP1 with two different T cell receptors. The integrin ␣ 4 ␤ 1 recognizes an LDVP sequence in the NH 2-terminal domain of TSP1 and was required for stimulation of T cell adhesion, chemotaxis,(More)
PURPOSE High-temperature requirement serine protease (HTRA1) was identified as a candidate age-related macular degeneration gene in multiple genetic studies in humans. To date, no functional studies have shown a mechanism for HTRA1 to instigate ocular tissue abnormalities. In the present study, the authors focused on a substrate of HTRA1, fibronectin,(More)
PURPOSE The glucocorticoid-induced TNF-related receptor (GITR) plays a pivotal role in regulating the suppressive function of CD4+CD25+ regulatory T cells. GITR is also involved in the inhibition of T-cell receptor-induced apoptosis and the upregulation of inducible nitric oxide synthase (iNOS). GITR expression on CD4+ T cells has been shown to correlate(More)
Due to the dynamic, heterogeneous and interorganizational nature, different web services and different ports or operations in the same service, even the same services at different times may have their different security requirements because of their different security domains and different business backgrounds. How to design a flexible, fine-grained and(More)
PURPOSE To evaluate the safety and efficacy of treating macular edema, secondary to noninfectious uveitis, with a humanized anti-CD11a antibody. METHODS Six patients received weekly subcutaneous treatments for 16 weeks according to this open-label, prospective, noncomparative phase I/II trial. Best corrected visual acuity (BCVA) and central macular(More)
PURPOSE To test the therapeutic effectiveness of voclosporin against experimental autoimmune uveoretinitis (EAU) in rats and to evaluate its effect on human T cells. METHODS EAU was induced by immunization with a uveitogenic protein. Voclosporin administration, by subcutaneous injection, began on day (d) 0 or d7 after immunization. Treatment effectiveness(More)
PURPOSE To examine whether human T-cell leukemia virus type 1 (HTLV-1) could infect a human retinal pigment epithelial (RPE) cell line, ARPE-19, in vitro and to investigate its regulation. METHODS A coculture system with ARPE-19 and irradiated cells of an HTLV-1-producing T-cell line, MT2 was used to determine the permissivity of RPE to HTLV-1 infection(More)
