Immunological Tolerance and Autoimmunity

This topic covers the critical concepts of immunological tolerance—the immune system's ability to distinguish self from non-self—and its breakdown, leading to autoimmunity. It includes mechanisms of central and peripheral tolerance, the role of regulatory T cells (Tregs), and the induction of autoimmune diseases through molecular mimicry, sequestered antigens, and other pathways. For Zambian university and college students in Immunology, Biomedical Sciences, or Medical programs, this material is fundamental to understanding immune regulation and dysregulation. It is a core component of tertiary-level immunology curricula, such as that at the University of Zambia, and is frequently examined. Mastery of this topic is essential for diagnosing and managing autoimmune conditions, which are prevalent globally and in Zambia. It also provides a foundation for understanding transplantation immunology and developing tolerance-inducing therapies, crucial for advancing healthcare in the region.
