Reconstitution of T cell receptor signaling in ZAP-70-deficient cells by retroviral transduction of the ZAP-70 gene
A variant of severe combined immunodeficiency syndrome (SCID) with a selective inability to produce CD8 single positive T cells and a signal transduction defect in peripheral CD4+ cells has recently been shown to be the result of mutations in the ZAP-70 gene. T cell receptor (TCR) signaling requires the association of the ZAP-70 protein tyrosine kinase with the TCR complex. Human T cell leukemi...
متن کاملIn vivo correction of ZAP-70 immunodeficiency by intrathymic gene transfer.
SCID patients have been successfully treated by administration of ex vivo gene-corrected stem cells. However, despite its proven efficacy, such treatment carries specific risks and difficulties. We hypothesized that some of these drawbacks may be overcome by in situ gene correction of T lymphoid progenitors in the thymus. Indeed, in vivo intrathymic transfer of a gene that provides a selective ...

15 صفحه اولZAP-70: an essential kinase in T-cell signaling.
ZAP-70 is a cytoplasmic protein tyrosine kinase that plays a critical role in the events involved in initiating T-cell responses by the antigen receptor. Here we review the structure of ZAP-70, its regulation, its role in development and in disease. We also describe a model experimental system in which ZAP-70 function can be interrupted by a small chemical inhibitor.
متن کاملLck regulates the tyrosine phosphorylation of the T cell receptor subunits and ZAP-70 in murine thymocytes
The Src-family and Syk/ZAP-70 family of protein tyrosine kinases (PTK) are required for T cell receptor (TCR) functions. We provide evidence that the Src-family PTK Lck is responsible for regulating the constitutive tyrosine phosphorylation of the TCR zeta subunit in murine thymocytes. Moreover, ligation of the TCR expressed on thymocytes from Lck-deficient mice largely failed to induce the pho...
