Dr. Stephen O'Brien of the National Cancer Institute discovers a 700-year-old mutation that makes a person resistant to HIV infection. From Evolution: "Evolutionary Arms Race."
The application of Cas9-fusion proteins creates a greater cellular toolbox beyond gene disruption.
Although repeatedly exposed to HIV, Steve Crohn's blood cells were never infected. Dr. David Ho investigates in this video segment from NOVA: "Surviving AIDS."

Watch a discussion of health in Indian country including HIV/AIDS, diabetes, and other health care issues. [6:09]
This interactive introduces how HIV enters the host cell and uses its resources to
reproduce.
Understand the HIV virus that causes AIDS.
A free CK-12 account is required to view all materials.
Online presentations on more than 150 health topics, diseases, and conditions, from acne to viruses. Each plays as a slide presentation, with sound, that you can control or set to autoplay. Time varies from 5-20 minutes. Available in both Spanish and English.
Explore the body's immune system to understand how a virus enters the body and how the human body fights against the viruses like the mumps virus and HIV.
This pathway makes aware of scientific misconduct and introduces how it can be countered by research integrity.
In this video from Science City, meet Romiya Glover, a chemist who develops products for HIV/AIDS testing. She describes the multidisciplinary nature of her job, how she decided to go into science, and how her work benefits others.
Immune cell genes are sequenced after gene editing with CRISPR-Cas9. The goal is to identify a disrupted CCR5 gene in edited macrophages. Macrophages that don’t express CCR5 are resistant to HIV infection.
A GFP reporter gene is used to test CRISPR-Cas9 edited macrophages for HIV resistance.
Students simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups has already be tainted with the "virus" (sodium carbonate). After all the students have shared their liquids, the contents of the cups are tested for the virus with phenolphthalein, a chemical that causes a striking color change in the presence of sodium carbonate. Students then set about trying to determine which of their classmates were the ones originally infected with the virus.
UNICEF's youth section provides information on how to help this famous non-profit with its mission, a forum, real-life stories from people in less-developed countries, educational games and "what do you think" questions, and materials to help young people raise awareness about issues affecting youth around the world. The site is available in English, French and Spanish.
Students learn how viruses invade host cells and hijack the hosts' cell-reproduction mechanisms in order to make new viruses, which can in turn attack additional host cells. Students also learn how the immune system responds to a viral invasion, eventually defeating the viruses -- if all goes well. Finally, they consider the special case of HIV, in which the virus' host cell is a key component of the immune system itself, severely crippling it and ultimately leading to AIDS. The associated activity, Tracking a Virus, sets the stage for this lesson with a dramatic simulation that allows students to see for themselves how quickly a virus can spread through a population, and then challenges students to determine who the initial bearers of the virus were.
