Rosmarinic acid (RosA) is a hydroxylated compound frequently found in herbal plants and is mostly responsible for anti-inflammatory and antioxidative activity. Previously, we observed that RosA inhibited T-cell antigen receptor (TCR)- induced interleukin 2 (IL-2) expression and subsequent T-cell proliferation in vitro. In this study, we investigated in(More)
Lck is a T cell-restricted Src family protein tyrosine kinase that plays pivotal roles in TCR-mediated signaling. We aimed to identify novel agents that could disrupt the molecular interaction of the Src homology 2-domain of Lck (Lck SH2) with its binding partners, with the expectation that this would impair TCR signaling and generate immunosuppression.(More)
BACKGROUND We previously demonstrated that rosmarinic acid (RosA) inhibits T-cell antigen receptor-induced T-cell activation and proliferation. In this study, we evaluated the ability of RosA alone and in conjunction with currently used immunosuppressive drugs to inhibit in vitro splenic T-cell proliferation and prolong skin graft survival in vivo.

Observations from nematodes to mammals indicate that insulin/insulin-like growth factor signaling (IIS) regulates lifespan. As in other organisms, IIS is conserved in mosquitoes and signaling occurs in multiple tissues. During bloodfeeding, mosquitoes ingest human insulin. This simple observation suggested that exogenous insulin could mimic the endogenous(More)
In this study, the authors isolated morphologically different capillary endothelial cells, designated as BCE-1 and BCE-2 cells, from bovine adrenal cortex. By a series of experiments involving proliferation, migration, and tubular-like structure formation assays, the authors found that the two BCE clones showed a clearly different response to basic(More)
Angiogenesis is closely associated with osteoblast differentiation. Previously, we demonstrated that bone formation can be accelerated by treatment with COMP-Angiopoietin1, a known angiogenic factor. Angiopoietin1 (Ang1) is a specific growth factor that generates stable and mature vasculature through the Tie2 receptor. In this study, we aimed to identify a(More)
The antagonists for the SH2 domain are regarded as novel therapeutic candidates for cancer, autoimmune disease, and chronic inflammatory disease. Previously, we identified rosmarinic acid (alpha-o-caffeoyl-3,4-dihydroxyphenyl-lactic acid; RosA) from Prunella vulgaris as an antagonist for the p56lck SH2 domain by screening natural products. RosA not(More)
Machine recognition of emotion has become one of the main targets for developing next-generation user interaction in computer systems. While affect recognition technology has achieved substantial progress recently, the application of user emotion recognition to software user interface is in its early stages. In this paper, we describe the development of an(More)
