Purpose:
Deficient CD3-zeta chain expression in T cells of patients with idiopathic SLE is associated with T cell receptor/ /CD3 complex (TCR/CD3)-mediated signaling defect. Hydralazine (HYD) inhibits expression of DNA methyltransferase 1 (DNMT1) and may cause a lupus-like disease in man.
Material And Methods:
To explain the HYD effect on intracellular level of CD3-zeta chain in Jurkat T leukemia cells clone E6-1, we employed the flow cytometric analysis.
Results:
We observed a dose-dependent increase in cellular content of CD3-zeta chain in Jurkat T cells treated with HYD. Our results suggest that HYD may result in T cells dysfunction different from this observed in idiopathic SLE T cells.
Conclusions:
This difference may partially explain distinct disease course in patients with HYD induced and idiopathic SLE.
