The T cell surface molecule CD28 can provide costimulatory signals that permit the full activation of T cells. Here we demonstrate that stimulation of CD28, either by B7, its natural ligand, or by the anti-CD28 monoclonal antibody 9.3, induces an association between CD28 and phosphatidylinositol 3-kinase (PI3-K) in Jurkat T cells, raising the possibility(More)
A novel series of adenosine A(2A) receptor antagonists was identified by high-throughput screening of an encoded combinatorial compound collection. The initial hits were optimized for A(2A) binding affinity, A(1) selectivity, and in vitro microsomal stability generating orally available 2-aminoimidazo[4,5-b]pyridine-based A(2A) antagonist leads.
Monocyte infiltration is implicated in a variety of diseases including multiple myeloma, rheumatoid arthritis, and multiple sclerosis. C-C chemokine receptor 1 (CCR1) is a chemokine receptor that upon stimulation, particularly by macrophage inflammatory protein 1alpha (MIP-1alpha) and regulated on normal T-cell expressed and secreted (RANTES), mediates(More)
Peer assessment is rapidly growing in online learning, as it presents a method to address scalability challenges. However, research suggests that the benefits of peer review are obtained inconsistently. This paper explores why, introducing three ways that framing task goals significantly changes reviews. Three experiments manipulated features in the review(More)
Research suggests that online peer review can provide critical help to learners who would otherwise not be given individualized feedback on their work. However, little is known about how different characteristics of review systems impact <i>reviewers</i>. This extended abstract presents preliminary results from an online experiment examining how explicit(More)
Self-disclosure of performance information involves the balancing of instrumental, learning benefits (e.g., obtaining help) against social costs (e.g., diminished reputation). Little is known about young children's beliefs about performance self-disclosure. The present research investigates preschool- and early school-age children's expectations of(More)
This study examined gender stereotypes in peer ratings of femininity and masculinity for adolescent participants in three sports. Following a preliminary study of gender stereotyping of several sports, high school students rated unfamiliar cohorts each of whom was described in a single paragraph as either a male or female dedicated participant in one of(More)
Intuitive theories about the malleability of intellectual ability affect our motivation and achievement in life. But how are such theories shaped by the culture in which an individual is raised? We addressed this question by exploring how Indian children's and adults' attitudes toward the Hindu caste system--and its deterministic worldview--are related to(More)
A novel series of pyrrolidine heterocycles was prepared and found to show potent inhibitory activity of CCR1 binding and CCL3 mediated chemotaxis of a CCR1-expressing cell line. A potent, optimized triazole lead from this series was found to have acceptable pharmacokinetics and microsomal stability in rat and is suitable for further optimization and(More)
