Correcting autoimmune anomalies in autoimmune disorders by immunological means, employing the modified vaccination technique.

Our research group has developed a new vaccination technique in experimental animals that has the potential of correcting autoimmune anomalies in humans such as autoimmune disorders, cancer, and chronic infections, both prophylactically and therapeutically. The vaccination method is called Modified Vaccination Technique (MVT). The MVT necessitates the introduction of a purified target antigen (ag) and a specific antibody (ab) against the target ag in the form of immune complex (IC) to evoke the desired immune response outcome by ab information transfer in the injected recipient. The injected IC produces the same class of ab in the host, with the same specificity against the target ag, as resides in the inoculum. The MVT promises to provide a means of upregulating beneficial immune events and downregulating undesirable immune responses in individuals, thereby re-establishing normalcy/tolerance to self.

Preventing and treating chronic disorders using the modified vaccination technique.

It is anticipated that the ultimate solution for the prevention and termination of autoimmune disorders will be based on somehow manipulating the cells of the immune system to attain antigen (ag) specific downregulation and termination. In the last few years we have developed a new vaccination technique that we call "modified vaccination technique" (MVT). It has with equal effectiveness both prevented and terminated autoimmune disease causing events in an experimental autoimmune kidney disease model. We expect that our technique will be similarly applicable to the specific treatment and cure of numerous other chronic disorders presently treated only by drugs. The vaccine is composed of two components, an ag and a specific antibody against it. When these are combined at slight ag excess they constitute a vaccine which is capable of treating chronic ailments by redirecting immune response outcomes in the vaccinated host. Both components, like drugs, will have to be produced ex vivo in order to maintain uniformity, safety, efficacy, and specificity.

New vaccination technology for endogenous antigen-derived ailments.

Neither autoimmune disorders nor cancer can be prevented with treatment modalities that are currently available. These diseases are generally treated with immunosuppressive agents and cytotoxic drugs, both of which can cause numerous side effects. However, scientific evidence now exists to suggest that such endogenous antigen-derived ailments can be controlled and even terminated by immunological approaches. Both autoimmune disorders and cancer can progress into chronic, irreversible conditions because of the abnormal presentation of endogenous antigens to the cells of the immune system. By appropriate regulation of the autoimmune system, both types of ailments could be curable. This feature review describes various autoimmune events that may occur both to the benefit and the detriment of the host, and highlights a new vaccination technique against slowly progressive Heymann nephritis. This modified vaccination technique holds promise in the prevention and cure of autoimmune system-related disorders. The vaccination has been employed both against endogenous antigen-induced diseases (autoimmune disorders and cancer) and against exogenous antigens. In each study performed to date, the technique has been demonstrated to induce specific, predetermined immune response outcomes.

A modified vaccination technique for the prevention and treatment of an experimental autoimmune kidney disease.

The main purpose of this article is to introduce a promising new vaccination technique and to outline its efficacy and safety as demonstrated in an experimental autoimmune kidney disease. We have found that antigen (AG)-specific downregulation and/or upregulation of immune responses can be achieved by injections of immune complexes (ICs) which contain prepackaged information. This result is attained with the new vaccination method, a method developed in our laboratory which we have called "modified vaccination technique" (MVT). This MVT not only enables the prevention of pathogenic autoimmune events leading to the development of an experimental autoimmune kidney disease; it also allows, with equal effectiveness, therapeutic intervention to terminate the disease. With an injected IC containing predetermined immune response-inducing components, the process effectuates a specific antibody information transfer conferring advantages that go beyond its prophylactic and therapeutic applicability. Its specificity can induce a precise immune response to correct mishaps, for example, in conditions where the immune system overreacts to an autologous antigen or fails to recognize unwanted self (as in autoimmune disorders, cancer, etc.) Preformed ICs are nontoxic and nonirritant, evoke a predetermined antibody response without the use of adjuvants, cause no disturbance in the overall regulatory function of the immune system, and produce no side effects. We firmly believe that proper implementation of the MVT will be able to induce and maintain specific preventive and/or curative responses in a way that is both natural and more effective in patients with chronic ailments presently treatable only with drugs.

Effect of rat kidney fraction 3 (rKF3) antigen and specific IgM antibody against rKF3 on the progression of slowly progressive Heymann nephritis.

The aim of the present study was to find out if specific IgM (M) antibody (directed against rat kidney fraction 3 (rKF3)) or rKF3 antigen were able to influence disease progression in an experimental autoimmune kidney disease called slowly progressive Heymann nephritis (SPHN). The level of circulating autoantibodies (aabs) and the morphological and functional changes to the kidney were studied in six groups of rats. All of the treatment components (except post-treatment with M) used in the SPHN pre- and post-treated rats and post-treated-only rats had measurable beneficial effects (even during restimulation with the chemically modified renal antigen, 22 weeks after the induction of the disease) as demonstrated by diminished pathogenic IgG aab production, less severe kidney lesions, and proteinuria reductions. The injected rKF3 minimized progression best in this experiment, especially when administered in a pre- and post-treatment regimen. It is thought that the effect of rKF3 in the reduced progression of SPHN was due to increased production of specific IgM aabs, which in turn limited pathogenic aab production and continuous buildup of immune complexes in the glomeruli by facilitating removal or blockage of nephritogenic autoantigens from the circulation.

Downregulation of a pathogenic autoantibody response by IgM autoantibodies directed against the nephritogenic antigen in slowly progressive Heymann nephritis.

The purpose of the study was to find out if a new modified vaccination technique would be effective in downregulating immunopathological events during the course of an experimental autoimmune kidney disease (which is morphologically and functionally similar to Heymann nephritis) called 'slowly progressive Heymann nephritis' (SPHN). We have shown that the pathogenic IgG autoantibody (aab)-induced experimental autoimmune kidney disease process can be downregulated early on as well as during the chronic progressive phase, when rats were restimulated. The IgM aab, resulting from stimulation by immune complexes made up of rat kidney fraction 3 (rKF3) antigen and rat anti-rKF3 IgM antibody in antigen excess (MIC), can greatly diminish pathogenic aab production by removing or blocking nephritogenic antigens. Reduced IgG aab production limits the formation of damaging immune complexes (IC) in the glomeruli and development of proteinuria. At the end of the experiment 60% and 80% of the MIC-treated groups had no pathogenic IgG aab in their circulation, while all the untreated SPHN rats had high levels of IgG aab associated with disease progression manifesting in increased proteinuria and severe immune complex glomerulonephritis.
