The goal of the present study was to determine whether the kappa-opioid receptor agonist (ORA) U50,488 attenuates behavioral and primary afferent nerve responses to noxious colorectal distension (CRD) by sodium channel blockade. We tested the analgesic kappa-ORA (+/-)-trans U50,488, its enantiomers (-)-trans (1S,2S)-U50,488 and non kappa-ORA (+)-trans (1R,2R)-U50,488, and/or its diastereomer (-...

Glucagon-like peptide-2 (GLP-2) is a nutrient-responsive neuropeptide that exerts diverse actions in the gastrointestinal tract, including enhancing mucosal cell survival and proliferation. GLP-2 stimulates mucosal growth in vivo with an increased rate of protein synthesis. However, it was unclear whether GLP-2 can directly stimulate protein synthesis. The objective was to test critically wheth...

A hemodialysis patient with tuberculous peritonitis with hypercalcemia and high serum soluble interleukin-2 receptor (sIL-2R) and CA-125 levels is reported. An 82-year-old woman who had been on hemodialysis therapy for 6 years was admitted to our hospital for evaluation and treatment of hypercalcemia. Laboratory examination and radiologic studies revealed markedly increased serum sIL-2R and CA-...

By using mAb and flow cytometry, a constitutive expression of the p75 IL-2R was revealed in human peripheral blood CD8+ T cells and TCR delta-1+ T cells as well as in CD16+ NK cells. Anti-p75 IL-2R mAb almost completely inhibited the induction of cytolytic activity in these T cells by brief exposure to IL-2, as estimated by anti-TCR/CD3 mAb-targeted cytotoxicity. While anti-p55 IL-2R mAb alone ...

The recently cloned cytokine interleukin-15 (IL-15) shares several functional activities with IL-2 in different cell systems. Although IL-15 does not show sequence homology with IL-2, it uses components of the IL-2 receptor (IL-2R) for binding and signal transduction, namely, p75 (beta) and the p64 (gamma) chains of IL-2R. To evaluate whether IL-15 is involved in the activation of granular lymp...

OBJECTIVE In humans, multiple genes in the interleukin (IL)-2/IL-2 receptor (IL-2R) pathway are associated with type 1 diabetes. However, no link between IL-2 responsiveness and CD4(+)CD25(+)FOXP3(+) regulatory T-cells (Tregs) has been demonstrated in type 1 diabetic subjects despite the role of these IL-2-dependent cells in controlling autoimmunity. Here, we address whether altered IL-2 respon...

OBJECTIVE To validate the Person-Centered Dermatology Self-Care Index (PeDeSI) as a tool for clinical assessment and for potential use in research evaluation. DESIGN To date, no validated assessment measures exist to identify the education and support needs of patients living with long-term dermatological conditions and to enable them to self-manage as effectively as possible. The PeDeSI asse...

Brevinin-2R is a novel non-hemolytic defensin that was isolated from the skin of the frog Rana ridibunda. It exhibits preferential cytotoxicity towards malignant cells, including Jurkat (T-cell leukemia), BJAB (B-cell lymphoma), HT29/219, SW742 (colon carcinomas), L929 (fibrosarcoma), MCF-7 (breast adenocarcinoma), A549 (lung carcinoma), as compared to primary cells including peripheral blood m...

Glucagon-like peptide-2 (GLP-2) regulates energy homeostasis via effects on nutrient absorption and maintenance of gut mucosal epithelial integrity. The biological actions of GLP-2 in the central nervous system (CNS) remain poorly understood. We studied the sites of endogenous GLP-2 receptor (GLP-2R) expression, the localization of transgenic LacZ expression under the control of the mouse GLP-2...

IL-15 is critical for natural killer (NK)–cell development and function and for memory CD8 T-cell homeostasis. The IL-15 receptor consists of IL-15R , IL-2R , and the common cytokine receptor chain ( c). IL-15R is known to “trans-present” IL-15 to an IL-2R / c heterodimeric receptor on responding cells to initiate signaling. To investigate the importance of the IL-15R cytoplasmic domain, we gen...
