B lymphocytes in humans express ZAP-70 when activatedin vivo

ZAP-70 Restoration in Mice by In Vivo Thymic Electroporation

Viral and non-viral vectors have been developed for gene therapy, but their use is associated with unresolved problems of efficacy and safety. Efficient and safe methods of DNA delivery need to be found for medical application. Here we report a new monopolar system of non-viral electro-gene transfer into the thymus in vivo that consists of the local application of electrical pulses after the in...

Peripheral blood lymphocyte phenotype of ZAP-70⁺ and ZAP-70⁻ patients with B-cell chronic lymphocytic leukaemia.

BACKGROUND Up to now, the immune status of chronic lymphocytic leukemia (CLL) patients in association with the expression of zeta-chain-associated protein kinase 70 (ZAP-70) in leukemic cells has not been evaluated. AIM The aim of this work was the study of the peripheral blood (PB) T-lymphocyte phenotypes in ZAP-70-positive (ZAP-70(+)) and ZAP-70-negative (ZAP-70(-)) untreated patients with ...

ZAP-70 methylation status is associated with ZAP-70 expression status in chronic lymphocytic leukemia.

BACKGROUND AND OBJECTIVES ZAP-70 expression is a recognized prognostic marker in chronic lymphocytic leukemia (CLL). The aim of this study was to analyze whether the methylation status of the ZAP-70 gene is associated with expression of the ZAP-70 protein. DESIGN AND METHODS Patients with CLL (n=87), acute lymphoblastic leukemia (n=13), mantle cell leukemia (n=13) and splenic marginal zone ly...
