Retroviruses, apoptosis and autogenes

Area of Science:

• Immunology
• Genetics
• Aging Research

Background:

• Autoimmunity is a natural aspect of aging, potentially reversible and physiological.
• Autoimmune diseases arise from complex interactions including genetic, viral, hormonal, and psychoneuroimmunological factors.
• While immune response genes are understood, other genetic influences on autoimmunity remain largely unknown.

Purpose of the Study:

• To differentiate between natural autoimmunity and autoimmune disease.
• To introduce and define the concept of 'autogenes' as non-MHC genes influencing immune regulation.
• To explore the genetic basis of immune dysregulation leading to autoimmunity.

Main Methods:

• Conceptual proposal of 'autogenes' based on existing knowledge of genetic and immunologic factors.
• Analysis of genetic alterations (mutations, retrotransposon insertion) affecting immunoregulatory genes.
• Review of factors contributing to immune dysregulation, lymphoproliferation, and autoimmunity.

Main Results:

• Proposed the term 'autogene' for non-MHC genes impacting immune regulatory actions.
• Identified that genetic alterations in autogenes can lead to immune dysregulation.
• Linked these genetic alterations to predispositions for lymphoproliferation and autoimmune diseases.

Conclusions:

• Autoimmunity and autoimmune disease are distinct phenomena.
• Autogenes represent a critical class of non-MHC genes involved in immune regulation.
• Genetic alterations in autogenes are key contributors to the development of autoimmune diseases.
