T-B cell collaboration where T cells recognize immunoglobulin variable region peptides (Id-peptides) on MHC II molecules on B cells. The importance of BCR (B cell receptor ligation) and T cell help in such Id-driven T-B collaboration. The relationship of chronic Id-driven T-B collaboration to development of autoimmunity and B cell lymphomas.
Studies on bystander killing effected by Id-specific CD4+ T cells. The mechanisms by which tumors can escape killing by CD4+ T cells.
Development of DNA vaccines that as proteins target fused antigen to antigen presenting cells for induction of strong immune responses against influenza virus (The Vaccibody principle).
