HIV replication in white blood cells requires seven steps- entry, reverse transcription, integration, transcription, translation, assembly, release and maturation.
The replication process starts with the entry of the virus into a cell. After entering the cell reverse transcriptase enzyme converts viral RNA to DNA. It is transferred through the nucleus then; it is inserted into human DNA by HIV integrase enzyme. After insertion, this DNA is called as provirus.
Replication in detail- once integrated into the CD4 cell DNA, HIV begins to use the machinery of the CD4 cells to make long chains of HIV proteins which are the building blocks of more virus particles. Inside the CD4 cell nucleus, HIV releases integrase which is used to insert viral DNA into the CD4 DNA. Now this stage is provirus.

(Case 7) "THE HIV" Aja is a 24-year-old seeking prenatal care as she is one month pregnant with her first child. Her prenatal HIV antibody screen results positive for Human Immunodeficiency Virus-1. Aja reveals that she has a history of multiple sexual partners and no former antiviral therapy. Aja's bloodwork shows that her CD4 helper T-cell lymphocyte levels are normal, however, treatment with the antiviral drug AZT (also known as Zidovudine) is prescribed to aid in prevention of passing the...

Read the following scenario: K.D. is a 56-year-old professional man who has been human immunodeficiency virus (HIV) infected for 6 years. He had been on antiretroviral therapy (ART) with Combivir (zidovudine and lamivudine) and nelfinavir (Viracept). He stopped taking his medications 6 months ago because of depression. The appearance of purplish spots on his neck and arms persuaded him to make an appointment with his physician. At the physician's office, K.D. stated he had been feeling fatigued for several months...

A) HIV functions by infecting healthy CD4+T cells, a type of white blood cell, that are necessary to fight infection. As the virus embeds in a T cell and the immune system produces more of these cells to fight the infection, the virus propagates in an opportunistic manner. Normally, T cells are produced at a rate s and die at a rate d. The virus, when present in the bloodstream as free virus, infect health T cells at a rate...
