TESTING AND

HIV PROTEINS
“...analysis of the proteins
demands mass production
and purification”
Luc Montagnier 1997
Montagnier 1983

“Purified virus”
3 proteins react with patient serum

“Confusion over the identification of these
bands has resulted in incorrect
conclusions…some clinical specimens may
been identified erroneously as
seropositive…”

MORTIMER 1992 p24 NON-SPECIFIC
SCHUPBACH 1992 p24 IN 49/60

serologically indeterminate”
and “5/5 seronegative blood
donors”

TRANSPLANT RECIPIENTS
THE “HIV” PROTEINS p32
Henderson1987 studied the p30-32 and
p34-36 of "HIV purified by double
banding" in sucrose density gradients.
Comparison with the amino-acid
sequences of these proteins with Class II
histocompatability DR proteins proved
that "the DR alpha and beta chains
appeared to be identical to the p34-36 and
p30-32 proteins respectively”
Cellular origin also acknowledged by
other HIV experts such as Arthur 1995.
THE “HIV” PROTEINS- p17/18
Stricker 1987 Sera from AIDS patients bind to a
p18 protein bind to mitogenically stimulated but
uninfected in uninfected lymphocytes
Chassagne 1986 MCA to "HIV" p18 reacts with
dendritic cells in the lymphatic tissues of a variety
of patients with a number of non-AIDS related
diseases
Parravcini 1988 the "same pattern reactivity was
present in normal tissue taken from uninfected
individuals as in those taken from HIV positive
subjects”
Faulk 1991 MCA to “HIV” proves p17 present in
normal, uninfected human placenta
HIV PROTEINS IN NORMAL HUMAN
PLACENTA p18/p24/p120
Faulk and Labarrere 1991
Immunocytochemical reactivity using polyand monoclonal antibodies
“Placentae from 25 normal term
pregnancies were collected by vaginal
delivery...Antigens gp120 and p17 were
identified in normal chorionic
villi…Antigen p24…in villous
mesenchymal cells...localized to HLA-DR
positive cells”
WHY THE ANTIBODY REACTIONS?
Infectious agents (inc. mycobact, fungi)
Autoantibodies (many inc. actin & myosin)
Non-specific and cross reacting antibodies

“Currently available HIV
antibody tests are extraordinarily
accurate, both in terms of
sensitivity (the ability of the test
to give a positive finding when a
subject is truly HIV-infected) and
specificity (the ability of the test
to give a negative finding when a
subject is truly HIV-free)”.

The real purpose of scientific method
is to make sure Nature hasn't misled
you into thinking something you
don't actually know... One logical slip
and an entire scientific edifice comes
tumbling down. One false deduction
about the machine and you can get
hung up indefinitely.

Motorcycle Maintenance
