It is well known that tsunamis can produce gravity waves that propagate up to the ionosphere generating disturbed electron densities in the E and F regions. These ionospheric disturbances can be studied in detail using ionospheric total electron content (TEC) measurements collected by continuously operating ground-based receivers from the Global Navigation Satellite Systems (GNSS). Here, we pre...

We previously reported that precursors within the keratin (K) 8+5+ thymic epithelial cell (TEC) subset generate the major cortical K8+5- TEC population in a process dependent on T lineage commitment. This report demonstrates that expression of a cyclin D1 transgene in K8+5+ TECs expands this subset and promotes TEC and thymocyte development. Cyclin D1 transgene expression is not sufficient to i...

The Tec cytoplasmic tyrosine kinase is a member of a family of src-like proteins that are thought to play important roles in hematopoiesis. Here we describe the temporal and spatial expression of the Tec gene during embryogenesis and in the adult. Our data demonstrate that embryonic Tec expression is restricted to distinct hematopoietic cells as well as structures and cell types that share a co...

introduction respiratory distress syndrome (rds) is a current cause of morbidity in premature infants resulted from surfactant deficiency. the primary aim of this randomized study was to describe the feasibility of early administration of surfactant via a thin catheter during spontaneous breathing (tec) and compare its outcomes with the insure (intubate, surfactant, extubate) procedure material...

The generation of Th17 cells has to be tightly controlled during an immune response. In this study, we report an increase in a CD44(high)CD62L(-) Th17 subset in mice deficient for the protein tyrosine kinase Tec. CD44(high)CD62L(-) Tec(-/-) CD4(+) T cells produced enhanced IL-17 upon activation, showed increased expression levels of IL-23R and RORγt, and IL-23-mediated expansion of Tec(-/-) CD4...

Death receptor 3 (DR3), a member of the TNF receptor (TNFR) superfamily, is induced in human renal tubular epithelial cells (TEC) in response to injury. This study examined the expression and actions of TL1A, the principal ligand for DR3. In histologically normal tissue from biopsy or nephrectomy specimens of renal allografts, TL1A mRNA and protein were expressed in vascular endothelial cells b...

Tumor blood vessels are essential for tumor growth. Therefore, these blood vessels are potential targets for anti-cancer therapy. The purpose of this study is to develop anti-tumor endothelial cell (TEC) antibodies for delivering anti-cancer agents or drugs. To achieve this goal, we utilized the phage antibody display library method to create monoclonal antibodies in vitro. Accordingly, we deve...

The cytoplasmic protein tyrosine kinase Tec has been proposed to have important functions in hematopoiesis and lymphocyte signal transduction. Here we show that Tec-deficient mice developed normally and had no major phenotypic alterations of the immune system. To reveal potential compensatory roles of other Tec kinases such as Bruton's tyrosine kinase (Btk), Tec/Btk double-deficient mice were g...

BACKGROUND Activated infiltrating T cells play a crucial role in nephritic inflammation via the direct interaction with proximal tubular epithelial cells (TEC). Under inflammatory conditions, major histocompatibility complex class I and II molecules are upregulated on the surface of renal TEC, enabling them to function as "non-professional" antigen-presenting cells (APC) to activate T cells, an...
