Why is the selective expression of MHC Class II molecules on professional antigen-presenting cells crucial for immune system function?
It allows all body cells to present antigens and activate immune responses indiscriminately.
It prevents the immune system from recognizing any foreign antigens, avoiding autoimmune diseases entirely.
It ensures that helper T cells are activated only when appropriate, preventing unnecessary or harmful immune responses.
