Introduction to Lupus Erythematosus (LE) Lupus Erythematosus (LE) is a complex, chronic, and multi-systemic autoimmune disorder characterized by widespread inflammation, tissue damage, and a profound failure of the body’s immunological self-tolerance. Under normal physiological conditions, the immune system acts as an intricate defense network, identifying and neutralizing foreign pathogens while sparing the host’s own tissues. […]
Lupus Erythematosus: Definition, Pathophysiology, and Clinical Spectrum Lupus erythematosus (LE) is defined as a complex, chronic autoimmune disorder characterized by systemic inflammation that can affect virtually any organ or tissue in the body. Unlike localized autoimmune conditions, LE is considered a multisystemic illness, meaning its pathology spans multiple physiological systems, ranging from the skin and […]
Defining Autoimmunity: The Failure of Self-Tolerance Autoimmunity is a complex pathological condition characterized by a fundamental breakdown in the body’s ability to distinguish between its own tissues and foreign invaders. Normally, the immune system—a sophisticated network of cells, tissues, and organs—maintains a state known as immunological tolerance, ensuring that defensive reactions are strictly targeted toward […]
