HIV / AIDS Control the Natural Way
June 2010
Summary (4-5 sentences)
HIV is a strong pathogen that attacks the immune system by kill all if not most of the white blood cells in a body. Once HIV kills all or most of the white blood cells it becomes AIDs. HIV can be transmitted by sexual intercorse if proper protection is used or through less intimate contact like shaking hands. HIV is usually transmitted through two different liquids in the body, semen and blood.
· Background Information (from BC Science 8 Textbook)
o Explain the difference between AIDS and HIV.
Once the HIV attaches to the white blood cells and kills all/most of the white blood cells it becomes AIDS
After the HIV has attached to the white blood cells and most of them are dead it becomes AIDS
o People infected with HIV may die from other causes. Why?
People who have HIV can die from other causes because, HIV atachs the immune system. So when other pathogens vome to attach the immune system it is too weak to defend itself because it’s unable to call apon the Killer T cells or the B cells. A the person with HIV could die from a less serious disease like pneumonia.
o How is HIV transmitted?
HIV is usually transmitted through two different liquids in the body, semen and blood. It is usually transmitted when people are hasty and make poor decisions. For example when two people have intercorse and don’t use protection or sharing needles contaminated with infected blood. HIV also is transmitted through other type of contact like a handshake or a hug.
· Questions specific to Articleo What is the role of the CD8 + T cell?
They have to recognize and destroy the rogue cells, which is a cell that is contagious or cancerous.
o What occurs for T cells in the thymus? Where is the thymus located?
The thymus is were T cells are created. The thymus constantly creates and trains T Cells. It is located next to the heart.
o Does the HLA-B57 protein bind to more or fewer peptides than other HLA proteins?
The HLA-B57 binds a lot fewer peptides than HLA protenis.
o Why do the scientists think this is beneficial?
T cells trained by a HLA-B57 like protein are more likely to recognize mutated forms of viral peptides
