Guest guest Posted January 7, 2006 Report Share Posted January 7, 2006 Hi everyone! Sorry about this description, but I need some suggestions here- My son is unwell again after being very well for 2 weeks- Now he has some mucus, clear transparent but yellowish in color coming out of his bottom (without stools); it is smelly. I am not sure if this is an infection or a die off- he has started to take a E3Live product, which is a preparation of blue bacteria (which basically amount to low doses vitamins, minerals, fatty acids, lots of chlorophyll, amino acids (rich) and supposedly a protein with anti-viral activity. (see below). So I suppose a die off is possible, although somehow I rather doubt it. He is also on LDN since 7 weeks now. Has anyone seen this before? Any suggestions comments on what I should do? Thanks Lorene Apparently E3Love product contains cyanovirin-N (CV-N); this seems very interesting indeed- I'd love to know of much of this protein is present in the E3Live product? It seems that people are developing various expression system and purification for topical use (and possibly injection as seen in mice with Ebola virus), in E. coli and even in transgenic plants. Would be nice to know if it could be effective in the gut, before being digested? I read this: Since CV-N may be immunogenic in humans, methods for using CV-N for ex vivo inactivation of HIV in blood, plasma, or putative vaccines preferably would allow for its exclusion from biologicals for parenteral use. I suppose to have this ex-vivo plasma treatment could potentially be the last resort of treatment to inactivate viruses in individuals known to be infected (the the symptoms of that individuals will have to be serious and clearly identified to this infective agent to consider this sort of treatment, I think). I see also that this protein may be active against several viruses, including measles and herpes, but not vaccinia virus (see below). Anyhow, certainly very interesting, Please Perri let me know if you have any idea of the amounts of such proteins in your Algae product. Regards Lorene Antimicrob Agents Chemother. 2003 Aug;47(8):2518-25.

O'Keefe BR, Smee DF, Turpin JA, Saucedo CJ, Gustafson KR, Mori T, Blakeslee D, Buckheit R, Boyd MR. Molecular Targets Development Program, Center for Cancer Research, Frederick, land 21702, USA. The novel antiviral protein cyanovirin-N (CV-N) was initially discovered based on its potent activity against the human immunodeficiency virus (HIV). Subsequent studies identified the HIV envelope glycoproteins gp120 and gp41 as molecular targets of CV-N. More recently, mechanistic studies have shown that certain high-mannose oligosaccharides (oligomannose-8 and oligomannose-9) found on the HIV envelope glycoproteins comprise the specific sites to which CV-N binds. Such selective, carbohydrate-dependent interactions may account, at least in part, for the unusual and unexpected spectrum of antiviral activity of CV-N described herein. We screened CV-N against a broad range of respiratory and enteric viruses, as well as flaviviruses and herpesviruses. CV-N was inactive against rhinoviruses, human parainfluenza virus, respiratory syncytial virus, and enteric viruses but was moderately active against some herpesvirus and hepatitis virus (bovine viral diarrhea virus) strains (50% effective concentration [EC(50)] = approximately 1 micro g/ml) while inactive against others. Remarkably, however, CV-N and related homologs showed highly potent antiviral activity against almost all strains of influenza A and B virus, including clinical isolates and a neuraminidase inhibitor-resistant strain (EC(50) = 0.004 to 0.04 micro g/ml). When influenza virus particles were pretreated with CV-N, viral titers were lowered significantly (>1,000-fold). Further studies identified influenza virus hemagglutinin as a target for CV-N, showed that antiviral activity and hemagglutinin binding were correlated, and indicated that CV-N's interactions with hemagglutinin involved oligosaccharides. These results further reveal new potential avenues for antiviral therapeutics and prophylaxis targeting specific oligosaccharide-comprised sites on certain enveloped viruses, including HIV, influenza virus, and possibly others.

Dey B, Lerner DL, Lusso P, Boyd MR, Elder JH, Berger EA. Laboratory of Viral Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, land 20892-0445, USA. Cyanovirin-N (CV-N) is a cyanobacterial protein with potent neutralizing activity against human immunodeficiency virus (HIV). CV-N has been shown to bind HIV type 1 (HIV-1) gp120 with high affinity; moreover, it blocks the envelope glycoprotein-mediated membrane fusion reaction associated with HIV-1 entry. However, the inhibitory mechanism(s) remains unclear. In this study, we show that CV-N blocked binding of gp120 to cell-associated CD4. Consistent with this, pretreatment of gp120 with CV-N inhibited soluble CD4 (sCD4)-dependent binding of gp120 to cell-associated CCR5. To investigate possible effects of CV-N at post-CD4 binding steps, we used an assay that measures sCD4 activation of the HIV-1 envelope glycoprotein for fusion with CCR5-expressing cells. CV-N displayed equivalently potent inhibitory effects when added before or after sCD4 activation, suggesting that CV-N also has blocking action at the level of gp120 interaction with coreceptor. This effect was shown not to be due to CV-N-induced coreceptor down-modulation after the CD4 binding step. The multiple activities against the HIV-1 envelope glycoprotein prompted us to examine other enveloped viruses. CV-N potently blocked infection by feline immunodeficiency virus, which utilizes the chemokine receptor CXCR4 as an entry receptor but is CD4 independent. CV-N also inhibited fusion and/or infection by human herpesvirus 6 and measles virus but not by vaccinia virus. Thus, CV-N has broad-spectrum antiviral activity, both for multiple steps in the HIV entry mechanism and for diverse enveloped viruses. This broad specificity has implications for potential clinical utility of CV-N. Quote Link to comment Share on other sites More sharing options...
