This occurs through binding to FcRs on APCs that leads to activation of T helper Cells and subsequent enhancement of immune responses. Idiotype Network Antigen triggers antibody production. The antibody produced (Ab-1) not only react against the antigen, but they also serve as antigen themselves. This triggers the production of a second level of antibodies (Ab-2). In turn, these antibodies react against Ab-1 but serve to induce the anti-Ab-3 antibodies, and the process continues. At each step, the concentration of antibody available to provoke formation of an antibody is less than in the preceding step. As a result, a level is eventually reached at which there is insufficient antibody produced to provide and antigenic signal
