Epigallocatechin gallate (EGCG) (Figure 1a) is the major catechin component of green tea (Camellia sinensis). It has been shown to have antiviral properties against DNA viruses such as herpes simplex virus (HSV; Herpesviridae) [1], adenovirus (Adenoviridae) [2], human papilloma virus (HPV; Papovaviridae) [3], and hepatitis B virus (HBV; Hepadnaviridae) [4], and RNA viruses such as influenza vir...

The FBVE network The FBVE (Food-borne Viruses in Europe) network was initiated during a research project funded by the European Commission (contract QLK1-1999-00594). The aim of the network is to establish a framework for rapid, (pre-publication) exchange of epidemiological, virological and molecular diagnostic data on outbreaks of viral gastroenteritis and acute hepatitis due to hepatitis A an...

I N T R O D U C T I O N Our previous data [1] established that human and animal hepatitis viruses actively replicate in the organs rich in reticular cells and lymphoid elements (liver, spleen, lymph nodes, bone marrow), and viremia especially in transmitted parentherally transmitted hepatits is connected both with the blood plasma and leukocytes [2]. In our present study, a blood leukocyte cult...

The hepatitis B virus (HBV) belongs to a group of viruses termed hepadnaviruses. The 3.2 kb genome encodes for a variety of proteins involved in viral replication (p-gene), transactivation (x-gene), or encodes for structural proteins (c- and s-genes). Several viral and non-viral functions determine the clinical course of HBV infection. The hepatitis D virus resembles a viroid and requires the H...

The human hepatitis B virus (HBV) and the duck hepatitis B virus (DHBV) share several fundamental features. Both viruses have a partially double-stranded DNA genome that is replicated via a RNA intermediate and the coding open reading frames (ORFs) overlap extensively. In addition, the genomic and structural organization, as well as replication and biological characteristics, are very similar i...

Viruses can only reproduce by infecting live cells. During their replication, some viruses manipulate the host cell machinery in such a way that may cause the host cell to reproduce out of control and become carcinogenesis. These viruses are known as oncogenic viruses, also named as “tumor viruses” or “cancer viruses”. In 1909, Francis Peyton Rous showed that cancer could be transmitted through...

The prevalence of hepatitis in South Korea is relatively high compared to that in other high-income countries. For this reason, viral hepatitis infection not only affects the population's health, but also impacts national healthcare costs. This study was performed in order to estimate the individual economic costs of the hepatitis A, B, and C viruses as well as to determine, using nationally re...

background and aims: viral hepatitis is a global health problem with a high mortality rate. recently, a new flavi-like virus, provisionally named hepatitis g virus (hgv), has been described. hgv does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (pc...

Viruses are known to hijack the intracellular organelles, including mitochondria, endoplasmic reticulum, lipid droplets, and cytoskeleton promote its replication. The host responds invading viruses by mounting antiviral responses rearrangement of organelles. In particular, mitochondria one target organelles exploited their proteins suppress response. this review, we have comprehensively summari...
