Eek. I think this idea is nuts. Also, I believe there were studies
of TNF. In any event, TNF may well be part of the problem. To the
extent that a) AIDS is partly due to the death of many UNinfected CD4
cells and b) that excessive cell-death may be due in part to excessive
levels of TNF, this approach seems dangerous.
I think IL-2 might be, as Fauci suggests, a *slightly* better
approach, but that requires activation of all these quiescent,
infected cells--and unfortunately every other unnfected cell, too.
This is just not a reasonable idea and seems more likely to kill
It is wedded also to the notion that HIV disease is only successfully
fought with eradication. This may not be true--adequate viral
suppression may be sufficient to end progression to AIDS. (E.g.,
herpes viruses are often suppressed to the point of no pathological
sequelae without eradication.)
