Question

What is an autoimmune response?

Options

• An immune reaction that targets only foreign pathogens and harmful agents

• A protective mechanism that strengthens self-tissues against disease

• An immune reaction in which antibodies or immune cells are produced against the body's own antigens

• A response where the immune system becomes dormant and inactive

Answer 1

An autoimmune response is an immune reaction in which antibodies or immune cells are produced against the body's own antigens. This means the body's protective system begins to act against self-antigens rather than only against harmful foreign agents, representing a misdirection of immune activity.
