Pathophysiology of HIV
DEFINITION 4
Virus binds to CD4 receptor sites and enters the cell. Virus gets
genetic material from the host. Reverse Transcriptase takes HIV's
RNA and converts it to DNA HIV must get its DNA into T-cell and
place it within human DNA HIV makes an enzyme called Integrase
Integrase allows the viral DNA to be inserted into the host DNA
which completes the infection of the CD4 T-cell
TERM 5
Consequences
DEFINITION 5
All daughter cells from infected cells are infected Genetic
codes can direct the cell to make HIV The CD4 T-cell
becomes an HIV factory
