Methods for generating reagents to examine idiotype networks within antiviral immune responses

The use of anti-idiotypic antibodies to examine and/or modulate the immune response to various viral antigens has the potential to be of use in many diverse systems. This paper details the method and immunologic parameters used in our laboratory to generate and characterize anti-idiotypic antibodies (anti-Id or Ab-2) with specificity for antibodies directed against viral antigens. These anti-Id reagents have been used in our laboratory for studies involving the immune responses to hepatitis B virus and simian virus 40, which we describe here, as well as herpes simplex virus, and the human immunodeficiency virus. We have utilized these anti-Id reagents to examine the fine specificity of the idiotypes on antiviral antibodies in these systems and have attempted to modulate or induce specific antiviral immune responses. It is anticipated that the methods described herein will be helpful in analyzing the immune response in other viral systems including studies involving viral-receptor interactions.
