Tec family kinases have important roles in lymphocytes; however, little is known about their function in monocytes/macrophages. In this study we report that Tec family kinases are essential for M-CSF (M-CSF)-induced signaling pathways that regulate macrophage survival. Compared with wild-type bone marrow-derived macrophage (BMM) cultures, Tec(-/-)Btk(-/-) BMM cultures displayed increased cell d...

The time from admission to reperfusion in patients with acute myocardial infarction (AMI) was compared according to the type of hospital and treatment strategy. A total of 164 patients with a first AMI within 12h of onset were enrolled at one tertiary emergency center (TEC) and 6 community hospitals (CHs). The subjects were randomly assigned to receive either primary percutaneous transluminal c...

Studies of HIV-1-infected individuals on anti-retroviral therapies and of patients receiving lymphoablating treatments indicate that the thymus retains restorative capacity even in adults. The contributions of the thymic epithelial cells (TECs) to the regeneration of the thymus and the identity of epithelial cell progenitors were evaluated in murine models of transient thymic atrophy followed b...

There are many types of tyrosine kinase involved in intracellular mitogenic mechanism, particularly, Tec tyrosine kinase are involved in apoptosis pathway. Tec tyrosine kinases do not have any transmembrane domain so it is known as non receptor tyrosine kinase. There are various types of Tec tyrosine kinase like Txk, Btk, Itk, Rik and Bmx. These kinases have different protein or domain structur...

Previous analysis on the thymus of erythropoietin-producing hepatocyte kinases (Eph) B knockout mice and chimeras revealed that Eph-Eph receptor-interacting proteins (ephrins) are expressed both on T cells and thymic epithelial cells (TECs) and play a role in defining the thymus microenvironments. In the current study, we have used the Cre-LoxP system to selectively delete ephrin-B1 and/or ephr...

Human EMCs (extraskeletal myxoid chondrosarcomas) are soft tissue tumours characterized by specific chromosomal abnormalities. Recently, a proportion of EMCs were found to harbour a characteristic translocation, t(3;9)(q11-12;q22), involving the TFG (TRK-fused gene) at 3q11-12 and the TEC (translocated in extraskeletal chondrosarcoma) gene at 9q22. The present study used both in vitro and in vi...

Oxytocin (OT) has been shown to be the dominant peptide of the neurohypophysial family expressed by thymic epithelial and nurse cells (TEC/TNC) in various species. Thymic OT is not secreted but, after translocation of a hybrid neurophysin/MHC class I protein, is integrated within the plasma membrane of TEC, thus allowing its presentation to pre-T cells. In order to further demonstrate that thym...

abstract prediction of input flow into water resources is regarded as one of the most important issues in optimum planning and management in producing electro-water energy and optimum allocation of water into different consumption sources. different parameters affect on input discharge into dams. climate variables including temperature and rainfall have the most effect on input runoff rate to w...
