Introduction: What they say

A study from the Viral Populations and Pathogenesis Unit, Institut Pasteur, CNRS UMR 3569, 25–28 rue du Dr. Roux, 75724 Paris Cedex 15, France shows thatInterferon-Induced Spermidine-Spermine Acetyltransferase and Polyamine Depletion Restrict Zika and Chikungunya Viruses.”  This research paper was published, in the 10 August 2016 issue of the journal “Cell Host and microbe” [One of the best research journals in Infectious biology with an I.F of 12.552], by Prof. Marco Vignuzzi, Bryan C. Mounce and others.


What we say: 

On the foundation of this interesting finding, Dr L Boominathan PhD, Director-cum-chief Scientist of GBMD, reports, for the first time, that:  Epicatechin-3-gallate(ECG)-based antiviral therapy for chikungunya (CHIKV) and Zika (ZIKV) viruses: Epicatechin-3-gallate(ECG), one of the main components of green tea, increases spermidine/spermine N1-acetyltransferase (SAT) expression, depletes spermidine and Spermine levels, and restricts Chikungunya and Zika viruses replication via upregulation of its target gene


What is known?

Prof. Marco Vignuzzi’s research team has recently shown that induction of type I interferon results in: a) upregulation of SAT1; b) depletion of spermidine and spermine levels; and c) inhibition of Chikungunya and Zika viruses production. They have further validated this by showing that exogenous administration of Polyamines (spermidine and spermine) restores virus replication.


From research findings to Therapeutic opportunity:

This study suggests, for the first time,  a Probiotic(good bacteria)-based antiviral therapy for RNA viruses, such as Chikungunya virus (CHIKV) and Zika virus (ZIKV). Probiotic Lactobacillus Rhamnosus, by increasing the expression of its target gene, it may increase the expression of spermidine/spermine N1-acetyltransferase (SAT1) (Figure 1). Thereby, it may: (1) decrease polyamine spermidine and spermine levels; (2) stall CHIKV and ZIKV replication; (3) promote clearance of Zika and Chikungunya Viruses; and (4) strengthen antiviral immunity against RNA viruses. (Figure 2)

Thus, pharmacological formulations encompassing “Epicatechin-3-gallate(ECG), either alone or in combination with other drugs”, may be used to treat infections caused by chikungunya (CHIKV) and Zika (ZIKV) viruses. Given that Green tea-derived Epicatechin-3-gallate(ECG is more safe and economical compared with chemical-based anti-viral therapy, it may find larger utility in patient care as an antiviral agent.
