WebDec 1, 2024 · One therapeutic, ITV-1, a patented antiviral peptide that has been clinically tested, is a suspension of Inactivated Pepsin Fragment (IPF), a purified extract of porcine pepsin. This therapeutic has been shown to strengthen the immune system and has been tested in HIV patients in clinical trials with significant beneficial results. WebPepsin is widely used to produce F(ab')2 fragments of immunoglobulin G (IgG). In many cases, at least part of the pepsin will remain present in the F(ab')2 preparation, albeit in (irreversibly) inactivated form. Here we report on a potent immunomodulatory effect of irreversibly inactivated pepsin on activated human neutrophils.
