Definition and Classification
Autoimmune diseases are characterized by a malfunction in the immune system. The body’s defense mechanism, which typically protects against pathogens, turns on itself, leading to tissue damage. There are two main categories of autoimmune diseases: organ-specific and systemic disorders. Organ-specific diseases, such as Hashimoto's thyroiditis, affect a single organ. Systemic diseases, like systemic lupus erythematosus, can impact multiple systems in the body.
Key Points in Classification:
- Organ-specific autoimmune diseases: Target a particular organ.
- Systemic autoimmune diseases: Affect multiple areas, leading to widespread complications.
Immune System Functionality
The immune system functions as the body’s defense against diseases. It comprises various cells, tissues, and organs. White blood cells, antibodies, and lymphatic organs play prominent roles in identifying and eradicating pathogens. A well-functioning immune system is able to distinguish foreign particles from the body’s cells. However, in autoimmune diseases, this functionality fails.
"The interplay between immune system components is intricate, and disruptions can lead to autoimmunity."
Understanding how these components work together provides insights into why the immune system may become hyperactive against self-tissues. Factors such as genetic predisposition and environmental influences can alter the immune response.
How Autoimmune Diseases Develop
The development of autoimmune diseases often involves a blend of genetic and environmental factors. Certain individuals inherit genes that increase their susceptibility to autoimmunity. This genetic predisposition can be exacerbated by triggers such as infections, exposure to toxins, or hormonal changes. The pathway from a healthy immune response to an autoimmune reaction is complex and not yet fully understood.
Factors Influencing Disease Development:
- Genetic inheritance: Specific genes linked to autoimmunity.
- Environmental triggers: Infections and toxins that can initiate the immune attack.
