5-16 T Cell Memory

Work through the following questions, checking all the correct answers. For each question there may be more than one correct answer.

Which of the following properties are shared by central memory T cells (T_CM) and effector memory T cells (T_EM)?

Which of the following statements are true?

	a)	Central memory cells decline more rapidly with time than effector memory cells.
	b)	Memory T cells are less dependent than naïve T cells on costimuation by B7 for activation.
	c)	Central memory cells give a more rapid response than naïve T cells because the starting pool of antigen-specific cells is larger.
	d)	CD8 memory T cells are important for elimination of intracellular infections.
	e)	CD8 memory T cells are important for control of intracellular infections that cannot be eliminated.
	f)	Constant restimulation of CD8 memory T cells by persistent infection leads to a decline in their numbers with time.
	g)	CD8 memory T cells can provide limited immunity to viruses that are protected by rapidly mutating surface proteins.
