Idiotypic regulation of the immune system by the induction of antibodies against anti-idiotypic antibodies.
Anticarbohydrate antibodies (Ab1) were isolated from a rabbit hyperimmunized with Micrococcus lysodeikticus and injected into allotype-matched rabbits in order to obtain specific anti-iodiotypic antibodies (Ab2). Ab2 was isolated by means of a Sepharose column coupled to the anticarbohydrate antibodies and was injected into two allotype-matched rabbits. These latter rabbits produced specific an...
متن کامل1110 Immunization with Anti - Idiotypic Antibodies
Treatment with anti-idiotypic (anti-Id) a antibodies can, under certain experimental conditions, induce lymphocytes and antibodies of complementary specificity. Injection of minute amounts of anti-Id antibodies has been shown in several experimental systems to induce antigen-specific helper T cells (1-4) and to enhance the expression of the corresponding Id in subsequent antibody responses (5-9...
متن کاملTailored Immunogens Direct Affinity Maturation toward HIV Neutralizing Antibodies
Induction of broadly neutralizing antibodies (bnAbs) is a primary goal of HIV vaccine development. VRC01-class bnAbs are important vaccine leads because their precursor B cells targeted by an engineered priming immunogen are relatively common among humans. This priming immunogen has demonstrated the ability to initiate a bnAb response in animal models, but recall and maturation toward bnAb deve...
متن کاملAnti-idiotypic antibodies induce neutralizing antibodies to rabies virus glycoprotein.
Rabbit anti-idiotypic antibodies (alpha Id Ab) were prepared against five murine monoclonal antibodies (mAb) specific for the rabies virus glycoprotein. Four of the mAb were directed against three known, type-specific, neutralizing sites on the glycoprotein, and the other mAb was directed against a topographically uncharacterized, nonneutralizing epitope. An absence of significant cross-reactiv...
متن کاملAnti-idiotypic antibodies to anti-HLA receptors induced by pregnancy.
We have previously shown that lymphoblasts alloactivated in vitro acquire the capacity of stimulating the autologous mixed lymphocyte response. This response is anti-idiotypic in nature because lymphocytes so primed display accelerated memory responses only when restimulated by autologous lymphoblasts that have been alloactivated against the same HLA-DR antigen. Based on this observation we hav...
