Background As increasing numbers of dengue vaccines and therapeutics are in clinical development, standardized consensus clinical endpoint definitions are urgently needed to assess the efficacy of different interventions with respect to disease severity. We aimed to convene dengue experts representing various sectors and dengue endemic areas to review the literature and propose clinical endpoint definitions...
There is an unmet need for a dengue vaccine to further prevent the spread of this disease and contain the growing pandemic. To this end several vaccine companies and academic groups are actively pursuing the development of a tetravalent vaccine to prevent dengue. In the last few years progress has been made in this area, including the first results of a vaccine efficacy trial and improved understanding...
Dengue is a mosquito-borne viral disease of humans that has re-emerged in many parts of the world and has become an important international public health threat. Dengue incidence and geographical spread has dramatically increased in the last few decades and is now affecting most tropical and sub-tropical regions of the world. Despite extensive research efforts for several decades, no vaccines or therapeutics...
An effective vaccine for treating human papillomavirus (HPV)-associated malignancies such as cervical cancer should elicit strong T cell-mediated immunity (CMI) against the E6 and/or E7 proteins necessary for the malignant state. We have developed Venezuelan equine encephalitis (VEE) virus replicon particle (VRP) vaccines encoding the HPV16 E6 and E7 genes and tested their immunogenicity and antitumor...
We test the hypothesis that the translation machinery in cells infected by influenza A virus efficiently translates only mRNAs that possess the influenza viral 5′ untranslated region (5′-UTR) by introducing mRNAs directly into the cytoplasm of infected cells. This strategy avoids effects due to the inhibition of the nuclear export of cellular mRNAs mediated by the viral NS1 protein. In one approach,...
The 5 -terminal untranslated region (5 -UTR) of picornavirus RNA contains a series ofcis -acting elements required for the internal initiation of translation, including a pyrimidine-rich tract (PRT), which in entero- and rhinoviruses is located about 20 nts upstream from a silent AUG triplet in the vicinity of the translation initiation site. In hepatitis A virus (HAV) RNA, the PRT is only 12 nts...
