Methods in Screening Antiviral Drugs Against Enterovirus 71.

Methods Mol Biol 2021 ;2296:167-184

Department of Biological Sciences, School of Medical and Life Sciences, Sunway University, Kuala Lumpur, Selangor, Malaysia.

Enteroviruses 71 (EV71) is a single-stranded, neurotrophic RNA virus responsible for the numerous outbreaks of hand, foot, and mouth disease (HFMD) in the Asia-Pacific regions. HFMD primarily affects children to cause range of infection, from mild symptoms to acute flaccid paralysis, and hemorrhage. Despite increased incidence of EV71 epidemics globally and research against EV71 becoming prioritized, no antiviral agent against EV71 has yet been licensed and approved worldwide. Read More

Caregivers: the potential infection resources for the sustaining epidemic of hand, foot, and mouth disease/herpangina in Guangdong, China?

Arch Public Health 2021 Apr 23;79(1):54. Epub 2021 Apr 23.

School of Public Health, Sun Yat-sen University, Guangzhou, China.

Background: Although several measures have been taken to control hand foot and mouth disease (HFMD) and herpangina (HA), these two diseases have been prevalent in China for 10 years with high incidence. We suspected that adults' inapparent infection might be the cause of the continued prevalence of HFMD/HA infection in mainland China.

Methods: To explore the role of adults (especially caregivers) in the transmission process of HFMD/HA among children, 330 HFMD/HA cases and 330 healthy children (controls) were selected for a case-control study. Read More

SAMHD1 inhibits multiple Enteroviruses by interfering with the interaction between VP1 and VP2 proteins.

J Virol 2021 Apr 21. Epub 2021 Apr 21.

Institute of Virology and AIDS Research, Key Laboratory of Organ Regeneration and Transplantation of The Ministry of Education, The First Hospital of Jilin University, Changchun 130021, P. R. China.

Sterile alpha motif and histidine-aspartic acid domain-containing protein 1 (SAMHD1) possess multiple biological activities such as virus restriction, innate immunity regulation, and autoimmunity. Our previous study demonstrated that SAMHD1 potently inhibits the replication of enterovirus 71 (EV71). In this study, we observed that SAMHD1 also restricts multiple enteroviruses (EVs) including Coxsackievirus A16 (CA16) and Enterovirus D68 (EVD68), but not Coxsackievirus A6 (CA6). Read More

A hSCARB2-transgenic mouse model for Coxsackievirus A16 pathogenesis.

Virol J 2021 Apr 21;18(1):84. Epub 2021 Apr 21.

Institute of Medical Biology, Yunnan Key Laboratory of Vaccine Research and Development On Severe Infectious Diseases, Chinese Academy of Medical Science and Peking Union Medical College, No. 935 Alternating Current Road, Wuhua District, Kunming, 650118, Yunna, China.

Background: Coxsackievirus A16 (CA16) is one of the neurotropic pathogen that has been associated with severe neurological forms of hand, foot, and mouth disease (HFMD), but its pathogenesis is not yet clear. The limited host range of CA16 make the establishment of a suitable animal model that can recapitulate the neurological pathology observed in human HFMD more difficult. Because the human scavenger receptor class B, member 2 (hSCARB2) is a cellular receptor for CA16, we used transgenic mice bearing human SCARB2 and nasally infected them with CA16 to study the pathogenicity of the virus.

Essential Role of Non-Coding RNAs in Enterovirus Infection: From Basic Mechanisms to Clinical Prospects.

Int J Mol Sci 2021 Mar 12;22(6). Epub 2021 Mar 12.

Department of Epidemiology, College of Public Health, Zhengzhou University, Zhengzhou 450001, China.

Enteroviruses (EVs) are common RNA viruses that can cause various types of human diseases and conditions such as hand, foot, and mouth disease (HFMD), myocarditis, meningitis, sepsis, and respiratory disorders. Although EV infections in most patients are generally mild and self-limiting, a small number of young children can develop serious complications such as encephalitis, acute flaccid paralysis, myocarditis, and cardiorespiratory failure, resulting in fatalities. Established evidence has suggested that certain non-coding RNAs (ncRNAs) such as microRNAs (miRNAs), long ncRNAs (lncRNAs), and circular RNAs (circRNAs) are involved in the occurrence and progression of many human diseases.

Safety and Immunogenicity of a Stable, Cold-Adapted, Temperature-Sensitive/Conditional Lethal Enterovirus A71 in Monkey Study.

Viruses 2021 03 9;13(3). Epub 2021 Mar 9.

Temasek Life Sciences Laboratory, 1 Research Link, National University of Singapore, Singapore 117604, Singapore.

Enterovirus A71 (EV-A71) and coxsackievirus A16 (CA16) are major etiological agents of hand foot and mouth disease (HFMD) in children, which may result in fatal neurological complications. The development of safe, cost effective vaccines against HFMD, especially for use in developing countries, is still a top public health priority. We have successfully generated a stable, cold-adapted, temperature sensitive/conditional lethal EV-A71 through adaptive culturing in Vero cells at incrementally lower cultivation temperatures.

Regulation of RDN on Th1/ILC1 cell imbalance in HFMD patients caused by EV71 infection.

Chin J Nat Med 2021 Mar;19(3):205-211

Jiangsu Key Laboratory of Druggability of Biopharmaceuticals, School of Life Science and Technology, China Pharmaceutical University, Nanjing 210009, China. Electronic address:

Enterovirus 71 (EV71) infection is more likely to cause hand, foot and mouth disease (HFMD) in children, which can lead to neurogenic complications and higher mortality. As a commonly used clinical medicine, Reduning injection (RDN) helps to shorten the symptoms of patients with HFMD and facilitate the early recovery of children.

Viral determinants that drive Enterovirus-A71 fitness and virulence.

Emerg Microbes Infect 2021 Dec;10(1):713-724

Infectious Diseases Translational Research Programme, Department of Microbiology&Immunology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore, Singapore.

Hand, Foot and Mouth Disease (HFMD) is usually a self-limiting, mild childhood disease that is caused mainly by Coxsackie virus A16 (CVA16) and Enterovirus A71 (EV-A71), both members of the family. However, recurring HFMD outbreaks and epidemics due to EV-A71 infection in the Western Pacific region, and the propensity of EV-A71 strains to cause severe neurological complications have made this neurotropic virus a serious public health concern in afflicted countries. High mutation rate leading to viral quasispecies combined with frequent intra- and inter-typic recombination events amongst co-circulating EV-A71 strains have contributed to the great diversity and fast evolution of EV-A71 genomes, making impossible any accurate prediction of the next epidemic strain.

Two cases of hand, foot, and mouth disease caused by enterovirus A71 after vaccination.

Int J Infect Dis 2021 Mar 15. Epub 2021 Mar 15.

Institute of Pediatrics, The Kunming Children' s Hospital and Kunming Medical University, Kunming, PR China; Yunnan Key Laboratory of Children's Major Disease Research, Kunming, PR China. Electronic address:

Background: Enterovirus A71 (EVA71) is often identified as one of the main pathogens that lead to the vast majority of hand, foot, and mouth disease (HFMD) cases. In China, the proportion of HFMD cases caused by EVA71 decreases significantly after EVA71 vaccination; however, infection with EVA71 can still occur after vaccination.

Methods: The complete genomic sequencesof EVA71-KM18A and KM18B (from two rare cases of EVA71 infection after vaccination) were obtained and performed phylogenetic, nucleotide mutation,recombinant analyses, and comparative analysis of amino acid mutations. Read More
