How do autoimmune disorders primarily develop?

Autoimmune disorders primarily develop when the immune system mistakenly identifies the body's own tissues as foreign and mounts an attack against them. This can occur due to a combination of genetic predisposition, environmental triggers, and other factors that lead to a breakdown in the immune system's ability to distinguish between self and non-self. In autoimmune disorders, the immune response is misdirected, resulting in inflammation and damage to healthy tissues, which can affect various organs and systems in the body.

The focus on the immune system attacking body tissues highlights the fundamental mechanism underlying autoimmune conditions, such as lupus, rheumatoid arthritis, and multiple sclerosis. These disorders exemplify how the immune response can become self-destructive, leading to a range of symptoms and complications that can significantly impact a person's health and quality of life.

Other options may touch on relevant factors related to immune system dysfunction but do not accurately capture the primary mechanism by which autoimmune disorders develop. For instance, while genetic mutations can play a role, they are not the sole factor; it is the aberrant immune response that is central to autoimmune pathology.
