I am interested in the role of invariant Natural Killer T cells (iNKT) in the initial response to HBV infection inside hepatocytes. I have seen this cell line used in many such studies so I searched for it but I could not find the exact pathway where this is defective. To make it easier, I am interested in finding about how lipid antigens are loaded on the cell surface of these hepatocytes and using RMAS cell how can I block the pathway of transporting these molecules.
