1

Stage of HIV infection with the following clinical manifestations: high viral load, decreased CD4+, and a high transmission potential.

acute retroviral syndrome

2

A deadly, sexually transmitted disease caused by the human immunodeficiency virus, a retrovirus

AIDS

3

Cells of the immune system that are targeted by the HIV virus

CD4+ helper T cells

4

A coreceptor that allows the HIV virus to attack microphages

chemokine receptor

5

The stage if HIV infection that occurs after the brief early infection episode, in which the individual may remain asymptomatic for months and years and the virus continues replicating, but not as fast as during the acute phase.

clinical latency or chronic HIV infection stage

6

The virus GP120 must attach to this receptor in order to attach to the T cells

CXCR4

7

The second part of the life cycle: the joining of the virus protein and the CD4+ membrane which then allows entry

fusion

8

Substance on the outer surface of the HIV virus that binds to the CD4+ on dendritic cells

glycoprotein 120

9

Vaccines that are made from whole or fractions of viruses or bacterial antigens or the toxin produced by the bacteria antigens or the toxin produced by the bacteria

inactivated

10

A viral enzyme that allows the viral DNA to become integrated into the CD4+ cells own DNA

integrase

11

Vaccines created from weakened wild viruses or bacteria that can replicate without causing disease. They can create an almost identical immune response as active infection.

live

12

The enzyme that converts the viral RNA to DNA

reverse transcriptase

13

Immune complex mediated type of hypersensitivity, in which circulating antigen-antibody complexes accumulate and are deposited in the tissue. This accumulation triggers the complement system, causing local inflammation and increased vascular permeability, so more complexes accumulate

type 3 hypersensitivity

14

Cell mediated hypersensitivity, which involves a delayed processing of the antigen by the macrophages. Once processed, the antigen is presented to the T cells, resulting in releasing in the release of lymphokines that cause inflammation and antigen destruction

Type 4 hypersensitivity
