Viruses have shaped human history through devastating infections. In addition, virus infection may be responsible for up to 15% of cancer deaths. Nevertheless, certain viruses can be our “friends.” At the end of the 18th century, Edward Jenner used cowpox … Continue reading
The spread of viruses among cells, organs, and hosts is often mediated by structures that carry multiple viral genome copies, such as polyploid virions, virion aggregates, occlusion bodies, virus-containing lipid vesicles, and virological synapses. These structures increase the multiplicity of … Continue reading
miRNAs play significant roles in different diseases. By binding to target genes, miRNAs post-transcriptionally regulate gene expression. During viral infections, miRNAs manipulate the activities of viruses and host cells. Some viral miRNAs mimic cellular miRNAs, and interfere with cellular activities. … Continue reading
Zika virus (ZIKV) causes microcephaly, whereas other related pathogenic flaviviruses do not. To reach the fetal brain, a virus must be transported from the maternal to the fetal circulation, which requires crossing of the placental barrier. This study demonstrates that … Continue reading
Zika virus cannot replicate in mice – unless you knock out the mouse type I interferon with antibodies. As we know, Zika can replicate all too well in humans, but the pathogenesis and cell tropism of this troubling virus is … Continue reading
Dengue has represented a significant public health burden for a number of decades. Given the lack of dengue-specific drugs and limited availability of licensed vaccine, new methods for prevention and control are urgently needed. Researchers investigated whether genetic manipulation of … Continue reading
The first available dengue vaccine, CYD-TDV (Dengvaxia), is estimated to reduce the burden of dengue and be potentially cost effective in settings where infections with dengue are common. The Long-Term Safety, Public Health Impact, and Cost- Effectiveness of Routine … Continue reading
This week I’ve been talking to first year students about cell biology, discussing how much the environment of the cell varies from one site to another within the cell. Viruses “know” this and much virus replication is localized at particular … Continue reading
Every year more than 350 million people in over 120 countries contact dengue fever, which can cause symptoms ranging from aching muscles and a skin rash to life-threatening haemorrhagic fever. Researchers have struggled to create effective vaccines against dengue virus, … Continue reading
