Our body produces antibodies in response to foreign antigens. These antbodies are then themself very potent immunogens. Since these molecules are new to the body they should not be recognised as self.Thus the body should mount an immune response against these primary antibodies(i.e. produce antibody against this antibody. Further more similarily this secondary antibody should again elicit a further immune response.And this chain should continue.Which is an unending and impossible task.Why does it not happen.
Re: Why does our body not mount an immune response against our own antbodies.
