The Immune System
Anti-Bodies
Germ goes here
Specific anti-bodies are
produced against specific
antigens
Made by B-Cells
They neutralize and
inactivate germs.

The Immune System
Innate Immunity Acquired Immunity
Resistance of skin Destruction of organisms
by the acids in the
stomach
Chemical compounds in
the blood
Cells called
Macrophages that
ingest foreign objects
B-Cell Immunity T-Cell Immunity
Consist of B-cells
Produce Anti-Bodies
involved with
Primary and
Secondary response
Consists of T-Cells
T-Cells are:
T helper cells
T killer cells

HIV
The Life cycle of HIV
Fusion Binding to the host cell
Reverse Transcription incorporate HIVs genetic
material into DNAIntegration integrate the DNA of HIV with the DNA of
the host cell
Transcription a new strand of HIV genetic material is
made
Translation All the building blocks for a new virus are
gatheredAssembly The blocks are put together to form a new
HIV

HIV
CD4+ Count:
When your CD4+ count drops below
350 CD4+ cells/mm, they start with
ARV therapy
To measure the total CD4+ cells/mm in your blood.
It is an indicator of the strength of your immune system.
A normal man has between 500-1200CD4+ cells/mm
A low CD4+ count means a high viral
load in the blood
