Molecular biology of transaldolase

We have shown that changes in the level of transaldolase expression alter activity of the oxidative phase of the pentose phosphate pathway, NADPH production, and consequently, regeneration of intracellular glutathione and the maintenance of mitochondrial transmembrane potential. Transaldolase activity influences susceptibility to cell death signals, including Fas- and HIV-induced pathways. TAL serves as a critical determinant of tissue and cell type-specific functioning of the PPP and sensitivity to apoptotic signals.

Involvement of the HRES-1 Human Endogenous Retrovirus in SLE

The long-term objective of this project is to understand the role of the HRES-1 locus at 1q42 in pathogenesis of SLE.

Mitochondrial dysfunction in SLE

Mitochondrial dysfunction in T lymphocytes of SLE has been identified in the PIs laboratory in 2002. This work was based on the discovery of mitochondrial hyperpolarization (MHP) as an early checkpoint of apoptosis controlled by transaldolase. The project is focused on characterizing the molecular basis of mitochondrial dysfunction and its relationship to T cell activation and cell death pathway selection in SLE.
