Phospho-DARPP-32 (where DARPP-32 is dopamine- and cAMP-regulated phosphoprotein, Mr 32,000), its homolog, phospho-inhibitor-1, and inhibitor-2 are potent inhibitors (IC50 approximately 1 nM) of the catalytic subunit of protein phosphatase-1 (PP1). Our previous studies have indicated that a region encompassing residues 6-11 (RKKIQF) and phospho-Thr-34, of(More)
There are no antivirals or vaccines available to treat Enterovirus 71 (EV71) infections. Although the type I interferon response, elicited upon virus infection, is critical to establishing host antiviral innate immunity, EV71 fails to induce this response efficiently. Here we provide new insights into potential anti-EV71 therapy by showing that(More)
Position-specific entropy profiles created from scanning 306 human and 95 avian influenza A viral genomes showed that 228 of 4591 amino acid residues yielded significant differences between these 2 viruses. We subsequently used 15,785 protein sequences from the National Center for Biotechnology Information (NCBI) to assess the robustness of these signatures(More)
BACKGROUND The cutaneous manifestations of human enterovirus (HEV) infection are usually limited, such as hand-foot-mouth disease. By comparison, Stevens-Johnson syndrome (SJS) is a life-threatening severe cutaneous adverse reaction (SCAR), mainly caused by drugs. During the HEV outbreaks in 2010-2012 in Taiwan, we identified 21 patients who developed(More)
Enterovirus 71 (EV71) infection may be asymptomatic or may cause diarrhea, rashes, and hand, foot, and mouth disease (HFMD). However, EV71 also has the potential to cause severe neurological disease. To date, little is known about the molecular mechanisms of host response to EV71 infection. In this report, we utilized cDNA microarray to profile the kinetics(More)
Nine hundred and seventy-eight clinical specimens were examined taken from patients with respiratory tract viruses (RV)-like syndrome between November 1996 and July 1998. The study was undertaken to evaluate the effectiveness of centrifuge-enhanced shell vial cultures (SVC) containing Madin-Darby Canine Kidney (MDCK) cells, combined with immunofluorescent(More)
Infections of the novel avian influenza A H7N9 virus cause severe respiratory diseases and death. In this study, to develop highly sensitive methods for differentially detecting the H7N9 virus, multiplex and singular real-time reverse transcription polymerase chain reaction (RT-PCR) assays were established and examined by targeting the H7 and N9 genes of(More)
Human enterovirus D68 (EV-D68) was first reported in the United States in 1962; thereafter, a few cases were reported from 1970 to 2005, but 2 outbreaks occurred in the Philippines (2008) and the United States (2014). However, little is known regarding the molecular evolution of this globally reemerging virus due to a lack of whole-genome sequences and(More)
An influenza epidemic was detected in April 2009 at the border between the United States and Mexico. The virus was identified soon after to be a swine-origin influenza virus A (S-OIV A) (H1N1). This virus has an HA gene that is derived from the 1918 swine influenza virus and other genes from human, avian, and Eurasian swine influenza viruses. Clinically, it(More)
OBJECTIVE In 1998, an enterovirus 71 (EV71) epidemic in Taiwan was associated with hand, foot, and mouth disease (HFMD)/herpangina and involved 78 fatal cases. We measured EV71 seroprevalence rates before and after the epidemic and investigated risk factors associated with EV71 infection and illness. METHODS Neutralizing antibodies to EV71 were assayed(More)
