Here is what I'd call a "smoking gun," and not just for "HIV/AIDS," but for the arachidonic acid/"chronic inflammation" view of "disease:"
QUOTE: "...During both HIV infection in humans and SIV infection in macaques, the host immune system becomes highly activated, experiences increased destruction and decreased production of key immune effector cells and progressively fails as a result. In contrast, natural hosts for SIV infection, like sooty mangabeys, do not exhibit aberrant immune activation and do not develop AIDS despite high levels of ongoing SIV replication. Our studies sought to understand the basis for the very different responses to AIDS virus infections in different species," says Mark Feinberg, MD, PhD, the paper's senior author. Feinberg is a former investigator at the Emory Vaccine Center and the Yerkes Research Center and a professor of medicine at the Emory University School of Medicine. He currently serves as vice president of medical affairs and policy for vaccines and infectious diseases at Merck & Co., Inc.
The reasons are found in significant differences in immune signaling in a specific type of dendritic cells in AIDS-susceptible or resistant host species. Dendritic cells are part of the immune system that play a key role in alerting the body to the presence of invading viruses or bacteria, and in initiating immune responses that enable clearance of these infections. They detect the invaders using molecules called Toll-like receptors.
Feinberg's team found that in sooty mangabeys, dendritic cells produce much less interferon alpha--an alarm signal to the rest of the immune system--in response to SIV. As a result, the dendritic cells are not activated during the initial or chronic stages of SIV infection, and mangabeys fail to mount a significant immune response to the virus. In contrast to mangabeys, dendritic cells from humans and macaques that are susceptible to developing AIDS are readily activated by HIV and SIV.
The difference in whether or not dendritic cells become activated upon AIDS virus exposure in specific primate hosts appears to result from species-specific differences in patterns of Toll-like-receptor signaling. Because host immune responses are unable to clear AIDS virus infections, ongoing virus replication leads to unrelenting activation of the immune system in humans and macaques.
Unfortunately, rather than promoting clearance of the infection, chronic dendritic cell stimulation may result in chronic immune activation and significant unintended damage to the immune system in AIDS-susceptible species. Such chronic immune activation is now recognized to be a major driving force for the development of AIDS.
The observation that mangabey dendritic cells are less susceptible to activation by SIV may explain why mangabeys do not exhibit abnormal immune activation and do not develop AIDS. Thus, in mangabeys, the generation of a less vigorous immune response to SIV may represent an effective evolutionary response to a virus that is so resistant to clearance by antiviral immune responses...

Of course, it's crucial to determine if the more resistant animals have no AA or less AA in their cells than the ones that die of "AIDS," but these "scientists" are not pursuing their investigation objectively, nor with full knowledge of how chronic inflammatory issues can be controlled or lessened significantly. Instead, as is often the case today, very useful findings are filtered through lenses that don't allow the light of truth to come through. Rather, they see what they want to see, and this results in ridiculous explanations about what "HIV" does, in this particular case
The kind of problem they describe here is not uncommon, and can be replicated by doing things to organisms that do not involve "infectious disease," such as drug abuse. And in science, one needs to control all possible variables before one posits a formal hypothesis. Moreover, a virus can't do what they are arguing here, unless the conditions that allow it are present, such as a great deal of "oxidative stress" (which can occur with drug abuse). Thus, even if one believes "HIV" exists and can cause some amount of cell death, it could be controlled by altering the conditions that make it so active that it causes dangerous cell death and/or chronic inflammation. The claims often made by these folks, such as that "HIV" is "wiley," "mysterious," or possesses some sort of incredible cunning, are beyond ludicrous, and makes one think that such people have been watching too many science fiction movies. |
