It has been previously shown that B-cell receptor BCR repertoire expressed by clonal B-cells involved in type II MC as well as in HCV-associated NHL is constrained to a limited number of variable heavy VH - and light VL -chain genes. Among these the VK3-20 light chain idiotype has been selected as a possible target for passive as well as active immunization strategy. In the present study we describe the results of a multiparametric analysis of the innate and early adaptive immune response after ex vivo stimulation of human immune cells with the VK3-20 protein. This objective has been pursued by implementing high-throughput technologies such as multiparameter flow cytometry and multiplex analysis of cytokines and chemokines. Introduction Hepatitis C virus HCV is a Hepacivirus of the Flaviviri-dae family mainly involved in hepatic disorders including chronic hepatitis which may progress to cirrhosis in about 10-20 of cases and further to hepatocellular carcinoma in 1-5 of cirrhotic patients 1 . Subsequently the virus has been implicated as one of the major risk .
