Unfortunately there’s no cure, but ever since the outbreak 30 years ago in the United states, there have been many advances in drugs.5 The death of HIV has decreased, as well as the amount of people getting diagnosed. All in all, HIV has a unique life cycle with stages that it advances to, and has caused unwanted stigma and discrimination throughout the United States.
HIV follows specific steps in order to infect the host. In the first step of the HIV life cycle, binding occurs. In this step, HIV attaches itself to a specific white blood cell known as CD4.1 These cells are responsible for sending signals to activate the immune system response in helping detect harmful pathogens.2 Fusion of the HIV and CD4 envelope then allows HIV to enter the CD4 cell.1 Once in the cell, reverse transcriptase is released in order to convert HIV RNA into HIV DNA.1 Because of that, HIV is now able to enter the CD4 nucleus. HIV then uses another enzyme integrase which allows HIV DNA to combine with CD4 DNA.1 Soon after, HIV proteins are made from the machinery of CD4; those proteins are the blueprints in making more HIV.1 The new HIV proteins and RNA assemble into new immature HIV once in the surface of the cell.1The last step is budding, in this step the new HIV goes outside of…
