Molecular epidemiology of human enterovirus 71 strains in the Nanchang region of China in 2011.

This study shows that the C4 subgenotype strain of EV71 was prevalent in the HFMD cases of Nanchang in 2011, and it reports the first incidence of adults being infected by EV71 in the Nanchang region. Thus, the surveillance of HFMD epidemiology and monitoring of HFMD severity should be continued. PMID: 23514913 [PubMed - in process]

In this study, we investigated the antiviral effect of salvianolic acid B (SalB) on EV71. SalB is a major component of the Salvia miltiorrhiza root and has been shown to be an effective treatment for subarachnoid hemorrhages, and myocardial infarctions. HeLa cells were cultured in 12-well plates and treated with SalB (100 or 10 μg/mL) and 106 PFU/mL of EV71. SalB treatment (100 µg/mL) significantly decreased the cleavage of the eukaryotic eIF4G1 protein and reduced the expression of the EV71 capsid protein VP1. In addition, SalB treatment showed a dramatic decrease in viral infection, measured by immunofluorescenc...

In this study, the vp1 gene of Enterovirus 71 (EV71) and Coxsackievirus B3 (CB3) was inserted into the vector pET22b (+) to form the respective expression plasmids pEVP1 or pCVP1, and then transformed into Escherichia coli strain BL21 (DE3). The recombinant EVP1 or CVP1 protein was overexpressed successfully and effectively purified to homogeneity. Then, we identified that EVP1 and CVP1 protein could generate effectively specific humoral immunity and cellular immunity in mice, what's more, we determined the cross-protection of VP1 between EV71 and CB3 in a murine model. The results showed that immunization with EVP1 could ...

Human enterovirus A71 (HEVA71) causes hand, foot, and mouth disease (HFMD) in young children and is considered a major neurotropic pathogen but lacks effective antivirals. To identify potential therapeutic agents against HFMD, we screened a 502-compound flavonoid library for compounds targeting the HEVA71 internal ribosome entry site (IRES) that facilitates translation of the HEVA71 genome and is vital for the production of HEVA71 viral particles. We validated hits using cell viability and viral plaque assays and found that prunin was the most potent inhibitor of HEVA71. Downstream assays affirmed that prunin disrupted vir...

In this study, we achieved a murine mAb, named 5A3, specifically toward EVA71 2Apro by using the traditional hybridoma technique. The mAb 5A3 recognizes 2Apro of both EVs A and B species, which was demonstrated by indirect fluorescent assay and Western blotting. Furthermore, a conserved N-terminal epitope on 2Apro recognized by mAb 5A3 was defined by using an overlapping peptide-based enzyme-linked immunosorbent assay (ELISA). Therefore, the unique mAb targeting conserved EVs 2Apro can be used as an important tool during both identifying the causative agent of HFMD and elucidating the pathological mechanism of HFMD. PM...

Abstract Hand-foot-and-mouth disease is caused by human enteroviruses and coxsackieviruses. Outbreaks can occur in the spring to fall and are common in North America, and most cases occur in patients younger than 10 years. Hand-foot-and-mouth disease is transmitted by fecal-oral, oral-oral, and respiratory droplet contact. Patients present with a low-grade fever, a maculopapular or papulovesicular rash on the hands and soles of the feet, and painful oral ulcerations. Lesions usually resolve in seven to 10 days; however, in rare cases, patients may have neurologic or cardiopulmonary complications. The differential ...
