AB HIV infection is characterized, at least in part, by the dysregulation
of the cytokine network. Both IFN gamma and IFN alpha are occasionally
overproduced. These cytokines could participate in the HIV-induced
immunosuppression. To enable a HIV-infected organism to promote an
immune reaction against the virus, the immune competence should
tentatively be restored by counteracting the overproduction of IFN alpha
because of its well known antiproliferative properties. For this
purpose, IFN alpha was chemically converted into a biologically
inactive, but still immunogenic product, which we termed kinoid,
reminiscent of that of bacterial toxins which have been transformed into
toxoids for vaccination. The kinoid derived from IFN alpha showed to be
well tolerated and immunogenic, since its administration to experimental
animals and humans should result in no untoward reactions, while
eliciting the production of anti-IFN alpha antibodies. Active kinoid
immunization should permit to counteract the overproduction of the
corresponding cytokine when involved in pathogenesis. Another
alternative, although less attractive than active anti-kinoid
vaccination, is passive immunization by administering anti-kinoid
antibodies. Biological antagonists of cytokine, as well as gene therapy
should also be taken into consideration.
