When the immune system improperly turns against the body's own molecules the result is?

When the immune system improperly targets the body's own molecules, it leads to autoimmune diseases. In these conditions, the immune system mistakenly identifies self-tissues as foreign and attacks them, resulting in inflammation and damage. Examples include conditions like rheumatoid Arthritis, lupus, and type 1 Diabetes. This dysregulation can significantly impair organ function and overall health.
