What is the Origin of Immune Tolerance?

The term originates directly from the field of immunology, with the concept of self-tolerance being established as a core principle in the mid-20th century, notably by Nobel laureates Frank Macfarlane Burnet and Peter Medawar. "Tolerance" is derived from the Latin tolerantia, meaning "endurance" or "patience," reflecting the immune system's controlled non-response.

What is the Mechanism of Immune Tolerance?

Tolerance is maintained through two primary, overlapping mechanisms: central tolerance, where developing lymphocytes that react strongly to self-antigens are eliminated in the thymus and bone marrow, and peripheral tolerance. Peripheral tolerance relies critically on regulatory T cells and the induction of anergy, a state of functional unresponsiveness in mature lymphocytes that encounter self-antigens without adequate co-stimulation. This active suppression mechanism prevents effector T cells from mounting an inflammatory attack on healthy tissue.

Immune Tolerance

Meaning

Immune Tolerance is the fundamental physiological state where the immune system is non-reactive to specific antigens, particularly those derived from the body’s own tissues, known as self-antigens, or harmless environmental substances. This crucial regulatory process prevents the development of autoimmune diseases and inappropriate inflammatory responses, maintaining a necessary state of systemic peace. In the context of hormonal health and wellness, supporting robust immune tolerance is key to mitigating chronic, low-grade inflammation often associated with age-related decline and endocrine disruption.

How Do Genetic Factors Influence Individual Immunological Responses to Injected Hormones?

Genetic factors modulate individual immunological responses to injected hormones by shaping antigen presentation, cytokine signaling, and immune cell receptor sensitivity.
