It can be made double stranded by an independent synthesis event. These different mechanisms will be described in more detail in the discussions of the different DNA viruses in Chapter 7. Download: Download full-size image FIGURE 1.9. Models for DNA replication in various virus groups. Since ...
However, replication of many viruses in reticuloendothelial organs (e.g., liver, spleen, lymph nodes, bone marrow), muscle, fat, and even vascular endothelial cells can play an important role in maintaining viremia.168 Download: Download full-size image FIGURE 134-7. Pathogenesis of mousepox ...
complete the prototype of the current virus classification system. According to ICTV MSL36 issued in 2021 (https://talk.ictvonline.org/files/master-species-lists/m/msl/12314), all viruses established as species can be classified into 6 realms, 10 kingdoms, 17 phyla (2 subphyla), 39 classes...
Viral genomes are highly versatile, and can be modified to direct their cytotoxicity towards cancer cells. These viruses are known as oncolytic viruses. How are viruses engineered to become tumour specific, and can they be used to safely treat cancer in humans? This is a preview of subscription...
Interestingly, some isolates can contain virus-free cells along with virus-bearing ones. Considering that the cultures underwent multiple passages, during which the cells had chances to become homogeneous in terms of viral infection status, two mutually non-exclusive explanations could be proposed: (1...
Gong, L. I. & Bloom, J. D. Epistatically interacting substitutions are enriched during adaptive protein evolution.PLoS Genet.10, e1004328 (2014).The study is a key example of how the specific genetic context in which mutations occur can have substantial effect on the resulting fitness of v...
Oncolytic viruses can kill tumour cells through a dual mechanism of action; the direct lysis of cells, and the induction of an immune response. The first oncolytic virus has been approved in China, and another has been recommended for approval in the Uni
Software that a user may perceive as unwanted. This may include adware, spyware, or browser hijackers. Such software may use an implementation that can compromise privacy or weaken the computer's security. Companies often bundle a wanted program download with a wrapper application and may offer to...
