Which is part of the immune system does HIV infect?
The HIV lifecycle. HIV infects a type of white blood cell in the body’s immune system called a T-helper cell (also called a CD4 cell).
Which is the most common opportunistic infection associated with AIDS?
In resource-limited nations, TB is the most common opportunistic infection associated with HIV. It’s a leading cause of death among people with AIDS. Cytomegalovirus.
How are HIV particles produced in the body?
The infected T-helper cell then produces more HIV proteins that are used to produce more HIV particles inside the cell. 4. Assembly, budding and maturation The new HIV particles are then released from the T-helper cell into the bloodstream which infect other cells; and so the process begins again. Protease inhibitor drugs stop this happening.

How is HIV spread in the human body?
About HIV/AIDS. HIV is a virus spread through certain body fluids that attacks the body’s immune system, specifically the CD4 cells, often called T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These special cells help the immune system fight off infections.
