In the present work we report the perturbations induced on multilamellar liposomes (MLVs) of different phospholipid composition (DPPC, DMPC, DMPC/DMPG) by peptides that belong to hepatitis G virus (GBV-CHGV). A differential scanning calorimetty (DSC) study was performed with MLVs in the presence of increasing amounts of the three synthetic overlapping peptides from GBV-C/HGV, namely E2(17-26), E2(12-26) and E2(7-26) sequences.
