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
Microbes, from the smallest viruses to the largest unicellular protists, dominate our oceans, playing a central role in ocean food webs and as key drivers of biogeochemical processes, yet the complex interactions and ecological significance of these relationships within and … 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
Seems like a great idea – the widespread use of insecticide coate bednets to cut the spread of malaria by mosquitoes (mostly active at night). Unfortunately nature is rarely that simple. Widespread use has driven mosquitoes to evolve resistance to … 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
Historically, bacteria have been thought of as simple cells whose only aim is to replicate. However, research over the past two decades has revealed that many types of bacteria are able to develop into communities that contain several types of … 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
