sPIF CLINICAL STUDY PROTOCOL IN AUTOIMMUNE HEPATITIS

Both sPIF as well as natural PIF appears to orchestrate a complex series of cytokine effects that overall appear to cause return of proper immune function and regulation rather than a nonspecific immune suppression. PIF acts on both the innate and adaptive arms of the immune system in a dynamic, diverse and synergetic manner "per need". In the pregnancy setting, PIF maintains basal immunity required for embryo and maternal survival, and aids in tolerance for self by blocking activated T cells proliferation that would otherwise harm the embryo. The activity of PIF appears to have a dual complementary mode of action that is dependent on whether the immune system is in the basal or the stimulated immune state. The sPIF concentrations that were used are in the same range as those that are present in maternal circulation of viable pregnancy. sPIF targets three major intracellular proteins that pivotal in autoimmune control.
