An AIDS-free generation would mean that virtually no child is born with HIV; that, as those children grow up, their risk of becoming infected is far lower than it is today; and that those who become infected can access treatment to help prevent them from developing AIDS and from passing the virus on to others.

The bodys immune system is like any other system of the body. Each of them have their vital function for the human host.

The immune systems goal is to protect the body against invaders either from without, such as microbes, or from within, such as cancers and different types of neoplastic transformation.

Exposures, if they are mild, in the sense of barely just a small concentration, it's mostly an irritant, particularly the peroxides, that in that smoke would irritate the skin or even irritate the lungs. So, for the most time, it could be either just a little bit of a nuisance irritant, or if you get a really big whiff of it, particularly people who have, for example, reversible airways disease, like asthma or different types of hypersensitivity diseases, you could get a serious problem.

I believe I have a personal responsibility to make a positive impact on society.

The nature of a protective immune response to HIV is still unclear. Because in a very, very unique manner, unlike virtually any other microbe with which we're familiar, the HIV virus has evolved in a way that the immune system finds it very difficult, if not impossible, to deal with the virus.

Investigating rare diseases gives researchers more clues about how the healthy immune system functions.
