The body is unable to tell the difference between pathogens and normal body cells when attacked by an autoimmune disease.

In autoimmune diseases, the immune system mistakenly identifies the body's own cells as foreign invaders, leading to an inappropriate immune response. This confusion can result in inflammation and damage to various tissues and organs. Examples of autoimmune diseases include rheumatoid arthritis, lupus, and multiple sclerosis. In each case, the immune system targets healthy cells, thinking they are harmful pathogens, which disrupts normal bodily functions and can lead to a variety of health complications. Understanding autoimmune diseases is crucial for developing effective treatments and managing symptoms effectively.
