Statement of the Problem: We have earlier by TUNEL staining established that overexpression of Wnt7a which is a ligand of the Vangl2 receptor increases apoptosis of Jurkat T-cells compared to control. The purpose of this study is to see how overexpression of Vangl2 affects apoptosis and inflammation. Methods: Jurkat T-cells were cultured on coverslips in 6-well plates until they became 80% confluent. They were transfected with a commercially bought Vangl2-GFP construct for 24 or 48 hours while the controls were transfected with green fluorescent protein (GFP). Results: The frequency of TUNEL stained cells were higher among the Jurkat T-cells that were transfected with Vangl2 compared to control cells. We could also see a rearrangement of p53 and Th17 expression which are important in inflammation. Conclusion: We conclude that Vangl2 overexpression affects apoptosis and hypothesize that this is done via caspase-8 signaling. We also suggest that the rearrangement of p53 and Th17 expression is a result of actin translocation from the cytoplasm into the nucleus and might be mediated by exosomes.
