Which of the following is not a component of an autoimmune response? The body's immune system targets its own tissues. Lymphocytes are produced that cannot discriminate between self and nonself. A normally harmless substance provokes an immune response in some people. An autoimmune response may be triggered by infection by a bacterium or virus such as HIV.

Which of the following statements is true of acquired immunity? It does not involve experience and its forms include phagocytosis and inflammation. Acquired immune responses take longer to initiate than natural immune responses. An effective immune response occurs even before prior exposure to a particular antigen. It consists of a number of inborn processes that help remove foreign substances from the body.

Herpes Simplex Virus 1 (HSV-1) causes lifelong infection with potential for multiple reactivation events. Which of the following explain why the virus can cause repeat episodes of disease with reactivation in the presence of a secondary immune response? O HSV-1 requires a state of immunosuppression of HSV 1 specific memory cells to allow for reactivation O HSV-1 lacks PAMPS to be recognized by lymphocytes HSV-1 produces protein A that will inhibit IgA activity in the saliva HSV-1 interferes with IL-2 secretion HSV-1 disables MHC I and interferon alpha to suppress immune recognition
