A patient is demonstrating signs of a delayed immunological response to a virus. Which of the following is responsible for beginning this response?
1. Intact functioning T cells
2. Intact functioning B cells
3. Complement
4. Functioning human leukocyte antigens
Intact functioning T cells
Rationale: T lymphocytes are the regulatory cells of the immune system whose function is to start and stop the immune process. When these cells are not functioning correctly, they will not chemically bind to an offending organism or cell and present the cell or organism to the B cells. The B cells are responsible for making antibodies to attach to the antigen. Complement is a protein made in the liver that coats an offending organism or cell to stimulate phagocytic cells to digest the cell or organism. Human leukocyte antigens are protein markers on the cell wall of white blood cells that inform the immune system if a cell belongs to the system or should be removed.
