What is the main function of clones in the immune system?
To fight infections by dividing and producing the same antigen receptor
What is the purpose of regulatory T cells in the immune system?

What is the process called when a B cell that attaches to a 'self' antigen is signaled for apoptosis and destroyed?
Peripheral tolerance
What is the function of IgM antibodies?
To be the largest antibody and the first produced during a primary immune response, great at binding to antigens and the complement system

To kill virus-infected cells
What is the purpose of seroconversion in the immune system?
To measure the reciprocal relationship between virus and antibody levels in the blood
How do antibodies help to fight viruses?
By coating the virus and preventing it from entering cells
What is the most severe form of immunodeficiency disease?

How do pathogens evolve to evade the immune system?
All of the above
What is the main treatment for Severe Combined Immunodeficiency Disease (SCID)?
Bone marrow transplant
What is the primary function of helper T cells in relation to HIV?

Which of the following is NOT a factor that has been implicated in the development of autoimmune diseases?
Viral infections
What is the role of the MHC (Major Histocompatibility Complex) molecule in organ transplantation?
It facilitates the recognition of foreign antigens by the immune system
What is the role of cancer vaccines in the context of cancer immunotherapy?
