In upper urinary tract infections, tubular epithelial cells (TEC) may play a pivotal role in the initiation of the renal inflammatory response. They exert crucial immunological functions such as processing and presentation of foreign antigen, secretion of proinflammatory cytokines (interleukin-6 [IL-6] and tumor necrosis factor alpha) and chemokines (IL-8, MCP-1, ENA-78, and RANTES). Since mono...

This paper introduces the concept of a Telecommunications Enhanced Community (TEC). The TEC is a community which has a variable mix of real and telecommunications services for reasons of community sustainability. Some telecommunications services may be dispensed with if a population increase results from successful implementation. We examine a number of theories that can support such a concept ...

Tourism English belongs to the English for Specific Purpose (ESP) and it has its own stylistic features. This paper aims at analyzing the stylistic features of tourism English. Firstly, a large amount of authentic materials are collected from official tourism websites of Britain and the U.S., and then a corpus named Tourism English Corpus (TEC) is compiled. Freiburg-LOB Corpus of British Englis...

MI: malignant intertrigo PPE: palmoplantar erythrodysesthesia SDRIFE: symmetrical drug-related intertriginous, flexural exanthema TEC: toxic erythema of chemotherapy INTRODUCTION Toxic erythema of chemotherapy (TEC) encompasses a broad spectrum of cytotoxic effects on the skin. Despite increasing awareness of TEC, such eruptions may remain unrecognized and subsequently result in unnecessary hos...

Tec is the prototypical member of the Tec tyrosine kinases family, which plays an important role in T cell signaling. We show in this study that Tec translocates to the immunological synapse when a T cell contacts a dendritic cell. Surprisingly, the presence of the pleckstrin homology (PH) domain of Tec is not required for this accumulation, and despite a strong activation of 3'-phosphorylated ...

Interleukin-6 (IL-6), leukemia inhibitory factor, oncostatin M, IL-11, and ciliary neurotrophic factor constitute the IL-6 family of cytokines and play important roles in hematopoiesis, immune response, and nervous system. The receptors for the IL-6 family of cytokines share gp130 through which signals are generated, although the cytoplasmic region of gp130 does not contain any catalytic domain...

Thymic epithelial cells (TECs) are the predominant intrathymic source of the essential thymopoietin IL-7. Whether thymocyte-TEC interactions have a role in the regulation of IL-7 expression is not known. By exploiting IL-7 reporter mice in which yellow fluorescent protein expression identifies TECs expressing high levels of IL-7 (Il7(+) TECs), we show that Il7(+) TECs segregate from emerging me...

Thymocytes differentiate in the thymic microenvironment into immunocompetent T cell through the interaction with a variety of accessory cells, including thymic epithelial cells (TEC). TEC plays an important role in the selection process presenting self antigens in association with major histocompatibility complex (MHC) molecules to the maturing T cells. The T cell receptor recognizes the self a...
