Guest guest Posted October 7, 2003 Report Share Posted October 7, 2003 Anti-HIV activity of olive leaf extract (OLE) and modulation of host cell gene expression by HIV-1 infection and OLE treatment. Lee-Huang S, Zhang L, Huang PL, Chang YT, Huang PL. Department of Biochemistry, New York University School of Medicine, New York, NY 10016, USA. Sylvia.lee-huang We investigated the antiviral activity of olive leaf extract (OLE) preparations standardized by liquid chromatography-coupled mass spectrometry (LC-MS) against HIV-1 infection and replication. We find that OLE inhibits acute infection and cell-to-cell transmission of HIV-1 as assayed by syncytia formation using uninfected MT2 cells co-cultured with HIV-1-infected H9 T lymphocytes. OLE also inhibits HIV-1 replication as assayed by p24 expression in infected H9 cells. These anti-HIV effects of OLE are dose dependent, with EC(50)s of around 0.2 microg/ml. In the effective dose range, no cytotoxicity on uninfected target cells was detected. The therapeutic index of OLE is above 5000. To identify viral and host targets for OLE, we characterized gene expression profiles associated with HIV-1 infection and OLE treatment using cDNA microarrays. HIV-1 infection modulates the expression patterns of cellular genes involved in apoptosis, stress, cytokine, protein kinase C, and hedgehog signaling. HIV-1 infection up-regulates the expression of the heat- shock proteins hsp27 and hsp90, the DNA damage inducible transcript 1 gadd45, the p53-binding protein mdm2, and the hedgehog signal protein patched 1, while it down-regulates the expression of the anti-apoptotic BCL2-associated X protein Bax. Treatment with OLE reverses many of these HIV-1 infection-associated changes. Treatment of HIV-1-infected cells with OLE also up-regulates the expression of the apoptosis inhibitor proteins IAP1 and 2, as well as the calcium and protein kinase C pathway signaling molecules IL-2, IL-2Ralpha, and ornithine decarboxylase ODC1.

I don't understand what sort of dosages they would be talking about here -- can anyone explain? > Thank you very much, Marti Marti, Referencing the previous article written by Dr. Pivatera (he is the expert here :-)), it mentions the optimal dosages for HIV. Many of the benefits are derived from the accompanying flavonoids. Higher doses may be used as well, however a common sense approach would indicate starting with the minimal amounts recommended and progressing gradually to a larger doseage. The most fabulous attribute of this herb is that there is absolutely no 'side effects' other than the usual 'die-off' symptoms. Another very good reason to start with minimal amounts in my estimation. As I say, there isn't any toxicity from this herb, however the only drawback would be adjusting the dosages in case of extremely severe 'die-off' symptoms. The important thing is to 'listen' to your body and give it what it needs and not listen to the negative vibes coming from orthodox medicine. These herbs are 100% safe in every way when taken as directed. Allopathic medicine tries to instill fear regarding their use. This is so ludicrous. I have taken olive leaf extract for everything from a common cold or virus to high fevers, infections and some of the more serious illnesses. There are no ill effects other than minimal passing discomfort from 'die-off'. This is a normal detox effect! Experimentation is the key. Everyone is biologically different. These are only general guidelines put in place by Dr. Privatera who by the way uses this in his clinic on a daily basis. I can assure you that this doctor has all the right credentials and has studied this wonderful extract for years. This article is the result of many years of research. Best Regards, JoAnn Dr. Privatera's Recommended Dosages --- Olive leaf extract is currently available in the form of 500 mg. tablets. The routine dosage is one tablet every six hours or four throughout the day. Take the supplement between meals for best results. In the case of bad colds or flu, you can use two tablets every six hours. For acute infections, some individuals have taken more -- three and even four every six hours -- and reported rapid relief. If you encounter a " die-off " effect, cut back on the number of tablets you are taking or temporarily discontinue them until the symptoms subside. See the section on " die-off effect. " For healthy folks seeking more energy or the prevention benefits of olive leaf extract, we suggest one or two tablets a day. The younger and cleaner the body, the more responsive it is to supplements such as this. When a person becomes older and more toxic, more of the supplement is required to do the job.
