The modified vaccination technique designed to prevent and cure acute and chronic disorders.

In spite of enormous efforts there have been no solutions to date for preventing/terminating certain acute and chronic disorders of humans by vaccination or drugs. Yet it is well understood that if the target antigen (ag) could be presented appropriately to the cells of the immune system then solutions could be found. Recently, the Barabas research group has introduced and described the third vaccination method - called modified vaccination technique (MVT) - which has the ability to provide a corrective immune response in experimental animals with an autoimmune kidney disease.

Tolerance, loss of tolerance and regaining tolerance to self by immune-mediated events.

Autoimmunity has both beneficial and harmful aspects. Beneficial aspects include: (1) removal of released intracytoplasmic antigens (ags) (cells at the end of their life span or damaged by outside agents) by specific nonpathogenic IgM autoantibodies and mononuclear cells and (2) recognition and elimination of cancerous cells. In contrast, harmful aspects include: (1) mounting a pathogenic autoimmune response against a tissue-derived ag, a 'modified self,' resulting in autoimmune disease and (2) inability to recognize and eliminate a cancerous clone.

Regaining tolerance to a self-antigen by the modified vaccination technique.

Autoimmune diseases are initiated and maintained by complex immunopathological processes in environmental and genetic factor predisposed patients. In certain autoimmune diseases, the etiologies and pathogenesis of the conditions are quite well understood; yet in others, controversy surrounds as to why and how auto-injurious processes start. Clinical and laboratory examinations reasonably well define the state of progression/remission of an autoimmune disease and allow treatment according to observed findings.

Immunopathological events initiated and maintained by pathogenic IgG autoantibodies in an experimental autoimmune kidney disease.

The experimental models of Heymann nephritis (HN) and slowly progressive Heymann nephritis (SPHN) give us rare opportunities to investigate the etiologies and pathogenesis of two immunopathological processes in rats leading to: (1) autoimmune disease, where the autoimmune disease HN and SPHN is initiated and maintained by cross-reactive pathogenic IgG autoantibodies (aabs) directed against the renal proximal convoluted tubules' brush border (BB) cells - where the nephritogenic antigen (ag) is produced and localized - damaging and releasing BB associated nephritogenic ag into the circulation which in turn contributes to continuation of the autoimmune disease; and (2) immune complex glomerulonephritis, where the glomerular injury is initiated, proceeding into a chronic progressive disease by depositing immune complexes (ICs) - made up of a glomerular epithelial cell produced endogenous nephritogenic ag and the developing pathogenic IgG aab directed against the nephritogenic ag, and complement components - on the epithelial side of the glomerular basement membrane. We also observed how the normally functioning immune system is able to avert autoimmune disease developments by circulating specific non-pathogenic IgM aabs clearing the system of intracytoplasmic ags released from cells at the end of their life spans or following damage by toxic agents. We also described how an autoimmune disease SPHN can be prevented and when present terminated by the implementation of a new vaccination technique we have developed and call modified vaccination technique.

The role of autoimmunologists in investigating and treating autoimmune disorders.

The role of an autoimmunologist is to investigate and cultivate knowledge of normal and abnormal immune responses against self, which includes developing practical know-how to manipulate autoimmune activity and direct positive autoimmune outcomes. Where a subject develops an abnormal immune response directed against normal self, resulting in an autoimmune disease, the specialist should be able to diagnose the problem and institute an appropriate treatment. Obversely, where a subject lacks an immune response against cells bearing antigens that are abnormal or not quite self, i.

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.

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.
