Summary Introduction
Introduction: HIV refers to the human immunodeficiency virus that causesacquired immunodeficiency syndrome(AIDS) in humans. This virus attacks the immune system of the body and interferes with the body’s ability to fight against infections.

Prior to entry, the _________ glycoprotein of the HIV virus recognizes the ______ receptor on the surface of the macrophage.
a. CCR5; gp120
b. CXCR4; CCR5
c. CD4; CCR5
d. gp120; CD4
We are confronted with a new RNA virus that uses x-proteins to attach to host cells and primarily infects liver cells. Based on this we would expect: (2 answers only)
a. possible latent infections
b. viral susceptibility to valacyclovir
c. viral suspeptibility to RNA->RNA pol inhibitor
d. symptoms of hepatits
Identify the statement that does not provide accurate evidence as to why HIV is so lethal.
a.
During the course of infection, HIV increases immune activation by altering intestinal physiology to let more microbes into the blood supply.
b.
Immune evasion increases in many infections due to HIV virions evolving new and unrecognizable epitopes (antigens).
c.
In many individuals the virus population evolves to use different receptors to gain access to a greater diversity of host immune cells.
d.
HIV causes enhanced replication and proliferation of T cells, which allows the immune system to work better at defending against pathogens.
