Chapter 51: The Immune System

Objective: Explain what research is taking place on the bodies own defense mechanisms against viral attack.


1.	What naturally produced molecule is being studied in this particular area of research?

		A)	Insulin
		B)	Prothrombin activator
		C)	Acetylcholine
		D)	Stat1

2.	Who are the first responders to cell viral invasion?

		A)	Antibodies
		B)	Phagocytes
		C)	Interferon proteins
		D)	T-cells

3.	How does Stat1 work?

		A)	Interferons give warning messages to Stat1 molecules at cell borders which activate the production of genes to prompt viral fighting responses.
		B)	Stat1 serves as a pyrogen causing elevated body temperature to help fight the virus infection.
		C)	It is a type of antibody which attacks the protein coat of the virus.
		D)	Phagocytes are alerted by Stat1 to come to the site of virus attack and destroy the cells which have been damaged.

4.	What method is being proposed to introduce the HyperStat1 variety of protein into a person’s body?

		A)	Oral tablet
		B)	Benign virus through the lungs
		C)	Transdermal patch
		D)	Intravenously

5.	Which of the following is not a likely response by the body to interferon/Stat1?

		A)	fever
		B)	runny nose
		C)	body aches
		D)	skin rash
