View Full Version : Is this guy just an idiot ?

This may actually be an important finding, which likely will strengthen the Perth Group's "oxidative stress" idea (because there's a good chance it's not a "germ" but oxidative or nitrosative stress that causes the loss of IL-21), but whoever put this together doesn't seem to understand that "HIV" is supposed to knock out the CD4 cells, not the CD8 ones. Is there any way these passages make sense?

QUOTE: The reason deadly infections like human immunodeficiency virus (HIV) and hepatitis C never go away is because these viruses disarm the body's defense system. Researchers at the University of Alabama at Birmingham (UAB) have discovered that a key immunity protein must be present for this defense system to have a chance against chronic infection.

Research up to now has tried but failed to decipher the cross-talk between 'killer T-cells' and 'helper T-cells' in the fight against viruses. The new UAB study finds this cross-talk can only happen in the presence of interleukin-21, a powerful immune system protein. If interleukin-21 is missing for whatever reason, then the immune system's anti-viral efforts fail, said Allan Zajac, Ph.D...

"Adding interleukin-21 back in stimulates the immune response and controls the infection," Zajac said. "We demonstrate that the loss of this protein prevents the control of the infection and diminishes the function of the killer T-cells, specifically CD8 T-cells..." UNQUOTE.

UAB sure is proud of their "AIDS Science".
