Antibody-dependent enhancement (ADE) is an important safety concern for vaccine development against dengue virus (DENV) and its antigenically related Zika (ZIKV) because may prime deleterious antibodies to enhance natural infections. Cross-reactive targeting the conserved fusion loop epitope (FLE) are known as main sources of ADE. We design ZIKV immunogens engineered change FLE conformation but...

Adverse drug events (ADEs) may cause serious injuries including death. Spontaneous reporting of ADEs plays a great role in detection and prevention of them, however, underreporting always exists. Although several interventions have been utilized to solve this problem, they are mainly based on experience and the rationale for choosing them has no theoretical base. The vast variety of behavioral ...

Infection of the type II feline infectious peritonitis virus (FIPV) strain 79-1146 to primary feline alveolar macrophages and human monocyte cell line U937 was enhanced by the sera of cats experimentally infected with the 79-1146 strain, but not those of cats infected with KU-2 or UCD-1 strain of type I FIPV. The experiments using sera of cats with feline infectious peritonitis (FIP) and of cat...

We analyzed the endogenous requirement for Cerberus in Xenopus head development. 'Knockdown' of Cerberus function by antisense morpholino oligonucleotides did not impair head formation in the embryo. In contrast, targeted increase of BMP, Nodal and Wnt signaling in the anterior dorsal-endoderm (ADE) resulted in synergistic loss of anterior head structures, without affecting more posterior axial...

The use of embryonic stem cell (ESC) differentiation to generate functional hepatic or pancreatic progenitors and as a tool for developmental biology is limited by an inability to isolate in vitro equivalents of regionally specified anterior definitive endoderm (ADE). To address this, we devised a strategy using a fluorescent reporter gene under the transcriptional control of the anterior endod...
