What is the Origin of Autoimmune Reactions?

The term is a compound of "auto," meaning self, and "immune reaction," referring to the defensive response of the body's immune system. The medical understanding of autoimmunity solidified in the mid-20th century as scientists recognized that certain chronic conditions were not due to external pathogens but rather an internal self-attack. The concept belongs fundamentally to the domain of immunology, with profound implications for endocrinology where hormonal organs are frequent targets.

What is the Mechanism of Autoimmune Reactions?

The process begins when self-reactive T cells or B cells escape the normal regulatory mechanisms of immune tolerance. These rogue lymphocytes recognize specific self-antigens as foreign, leading to the production of autoantibodies or a cytotoxic T-cell response. Genetic predisposition, environmental triggers, and hormonal fluctuations, particularly involving sex steroids and glucocorticoids, are known to influence the initiation and severity of these aberrant immune responses.

Autoimmune Reactions

Meaning

Autoimmune reactions represent a pathological state where the body’s immune system mistakenly initiates a targeted response against its own healthy tissues and cells. This immunological error results in chronic inflammation and subsequent tissue damage, which can affect nearly any organ system, including endocrine glands. Clinically, these reactions are the underlying cause of autoimmune diseases, such as Hashimoto’s thyroiditis or Type 1 diabetes. The core issue is a loss of immunological self-tolerance.
