———- is the acquired inability to make an immune response against self-antigens
Homework Answers
Autoimmune disease is the acquired inability to make an immune response against self antigens.
Autoimmune disease occurs when a specific adaptive immune response is mounted against its own antigens . The normal consequence of an adaptive immune response against a foreign antigen is the clearance of the antigen from the body.

Provide two examples of how the immune response to bacterial antigens or toxins can cause severe disease and pathology. For each example, name the disease, the bacterial species, the corresponding bacterial toxin or antigen associated with the disease, and the immune response driving the pathology.

A host organism needs time, often days, to mount an immune response against a new antigen, but memory cells permit a rapid response to pathogens previously encountered. A vaccine to protect against a particular viral infection often consists of weakened or killed virus or isolated proteins from a viral protein coat. When injected into a person, the vaccine generally does not cause an infection and illness, but it effectively teaches the immune system what the viral particles look like, stimulating...

What’s the difference between a primary immune response and secondary immune response? Answer both in terms of the physiological responses and in terms of the mechanism by which it is achieved. Adaptive immunity is a response to a specific antigen. How does the adaptive immune system mount a specific response to an invading antigen? How is it possible to mount such a response to a wide array of antigens?
