Novel Naturally Occurring Mutations of Enterovirus 71 Associated With Disease Severity.

Infection with the re-emerging enterovirus 71 (EV-A71) is associated with a wide range of disease severity, including herpangina, encephalitis, and cardiopulmonary failure. At present, there is no FDA-approved therapeutics for EV-A71. Early diagnosis for the high-risk children is the key to successful patient care.

A Polysaccharide Purified From Acts as a Potent Mucosal Adjuvant That Promotes Protective Immunity Against the Lethal Challenge With Enterovirus A71.

Enterovirus A71 (EV-A71), the pathogen responsible for the seasonal hand-foot-and-mouth epidemics, can cause significant mortality in infants and young children. The vaccine against EV-A71 could potentially prevent virus-induced neurological complications and mortalities occurring due to the high risk of poliomyelitis-like paralysis and fatal encephalitis. It is known that polysaccharide purified from (PS-G) can effectively modulate immune function.

Hypoxia and therapeutic treatment of EV-A71 with an immune modulator TLR7 agonist in a new immunocompetent mouse model.

Background: Enterovirus 71 (EV71 or EV-A71) was first identified in California about half a century ago. In recent years, outbreaks of EV-A71 were prevalent worldwide, including Taiwan, Malaysia, Singapore, Japan, and China. Between 2008 and 2011, China alone reported 1894 deaths associated with EV-A71 infection.

Enterovirus 71 targets the cardiopulmonary system in a robust oral infection mouse model.

Severe infection with the re-emerging enterovirus 71 (EV71 or EV-A71) can cause cardiopulmonary failure. However, in patients' heart and lung, viral protein has not been detected. In mouse models, heart disease has not been reported.

Immunocompetent and Immunodeficient Mouse Models for Enterovirus 71 Pathogenesis and Therapy.

Enterovirus 71 (EV71) is a global health threat. Children infected with EV71 could develop hand-foot-and-mouth disease (HFMD), encephalitis, paralysis, pulmonary edema, and death. At present, no effective treatment for EV71 is available.

Curcumin Induces p53-Null Hepatoma Cell Line Hep3B Apoptosis through the AKT-PTEN-FOXO4 Pathway.

Objective: Curcumin (diferuloylmethane) is a yellow-colored polyphenol with antiproliferative and proapoptotic activities to various types of cancer cells. This study explored the mechanism by which curcumin induces p53-null hepatoma cell apoptosis.

Results: AKT, FOXO1, and FOXO3 proteins were downregulated after curcumin treatment.

A new animal model containing human SCARB2 and lacking stat-1 is highly susceptible to EV71.

Enterovirus 71 (EV71) is a major threat to children worldwide. Children infected with EV71 could develop subclinical infection and hand-foot-and -mouth disease (HFMD). In severe cases, patients could develop encephalitis, paralysis, pulmonary edema, and death.

Immunodeficient mouse models with different disease profiles by in vivo infection with the same clinical isolate of enterovirus 71.

Unlabelled: Like poliovirus infection, severe infection with enterovirus 71 (EV71) can cause neuropathology. Unlike poliovirus, EV71 is often associated with hand-foot-and-mouth disease (HFMD). Here we established three mouse models for experimental infection with the same clinical isolate of EV71.

Nucleic acid chaperone activity associated with the arginine-rich domain of human hepatitis B virus core protein.

Unlabelled: Hepatitis B virus (HBV) DNA replication occurs within the HBV icosahedral core particles. HBV core protein (HBc) contains an arginine-rich domain (ARD) at its carboxyl terminus. This ARD domain of HBc 149-183 is known to be important for viral replication but not known to have a structure.
