Black Death causes our body to ave turmors. Also it causes bloody vomit fever and tumors.
Tolerance exists when the immune system does not respond to a particular antigen. All cells and tissues in the body contain antigens that normally do not stimulate an immune response. The immune system is said to exhibit tolerance toward such antigens.
An allergy.
Food allergies occur when the immune system mounts an attack on certain proteins in certain foods. The substances in the food that trigger this immune-system response are called allergens. The immune system is a complex network of cells and molecules that help defend the body against foreign substances. When a properly functioning immune system detects a foreign substance, it responds to this threat by producing proteins called antibodies against the invaders. The antibodies will recognize and attack this foreign substance when they next encounter it. This "battle" is what causes the allergy symptoms.
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).

The definition of an immune system disease is a disease that causes over- or underactivity of the immune system. When the immune system is overactive, this is called an autoimmune disease.

An overreaction of the immune system to an otherwise harmless substance is called an allergic reaction. In allergies, the immune system mistakenly identifies the harmless substance as a threat and produces an exaggerated response, leading to symptoms such as sneezing, itching, or hives.
An antigen is a substance that triggers an immune response in the body, by stimulating the production of antibodies. This response helps the body to recognize and destroy harmful pathogens such as bacteria, viruses, or foreign substances.
Epilepsy is not an infection or a virus or anything like that, so the immune system is not relevant to it. You cannot "catch" epilepsy from someone. So the immune system does not respond to epilepsy. There is nothing that it can do.
Pathogens such as bacteria, viruses, fungi, and parasites can respond to antibodies produced by the immune system. Antibodies work by binding to specific antigens on the surface of pathogens, marking them for destruction by other immune cells. This antibody response is a key component of the adaptive immune system's defense mechanism against infections.
