Abstract:IntroductionAmong human cancers, B-cell lymphomas appear among the most susceptible to immunotherapeutic strategies, because of their high rate of response to monoclonal antibodies (mAbs) targeting the B-cell differentiation antigen CD20 and encouraging results from early phase clinical trials of tumor-specific therapeutic vaccines. 1 The availability of both passive and active immunotherapeutic agents against B-cell lymphomas has made them an important testing ground for the development of clinically effectiv… Show more
“…6 In this context, it is noteworthy that the chimeric mouse/rat Fc portion binds not or only marginally to the inhibitory low-affinity receptor FcγRIIb (CD32b), e.g., on B lymphocytes and platelets. 4 As the issue of abrogating the inhibitory FcγRIIb-engagement is central for improving effector mechanisms induced by mAbs such trastuzumab (anti-HER2/neu) or rituximab (anti-CD20), this feature of Triomab…”

“…Moreover, anti-idiotypic antibodies can mimic either non-protein or protein antigens. The two possible vaccinating antibodies whether it's Ab1 or Ab2 the end result will be the anti-anti-idiotypic response (Ab3) produced because of the host from the tumors that need antibody-dependent cell mediated cytotoxicity (ADCC), and further cell-mediated cytotoxic pathways including natural killer cells and cytotoxic T cells [36]. Once immunization is performed against TAA with antibodies that provoke internal mage antibodies they resulted in the clonal development of cells that play in the antitumor activity.…”

The foreign antigen that enters into the body is detected by the immune system through antigen presenting cells leading to the production of antibodies. The use of anti-idiotype antibodies is a new way to excite the immune response that identifies and eliminates the foreign antigens entered into the body. These Anti-idiotype antibodies have the ability to decrease the non-specific binding of the antigenic protein epitopes because of high specificity for the antigenic determinants. The anti-idiotype antibodies attach to the paratope of idiotype antibody and stimulate a precise immune reaction same as that of external antigen. The anti-idiotype antibodies are the peerless therapeutic candidate as they mimic the antigenic structure and potentiate antibody and cell-mediated immunity. Even in the absence of foreign antigen, these anti-idiotype antibodies have the potential to provide long-lasting immunity. The present review is about immune regulations by anti-idiotype antibodies with some success therapeutic stories. The previous research analysis is evidence of anti-idiotype antibodies as an excellent candidate for the development of both human and animal vaccines although it has some gaps that are needed to be addressed.
“…As with LDRT, rituximab induces apoptosis (65), and it is currently suspected that this apoptosis contributes to the induction of a specific antilymphoma immune response in mice (66). The ability of rituximab to enhance radiationtriggered apoptosis in lymphoma cells (67,68) has also been described.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
