Viruses Find a New Way to Hijack Cells
ثبت نشده
چکیده
Viruses travel light. Most carry just their genetic material and a few tools to break into the cells of their hosts — after that, they hijack the host’s own machinery to manufacture thousands of copies of themselves. In recent decades, biologists have gained a clearer picture of just how this heist is pulled off. Many viruses, it turns out, suppress the messages that cells send to control their daily operations. This information interference shuts down some cellular functions that the attacking virus doesn’t need, and boosts others.

Evolution of viruses and cells: do we need a fourth domain of life to explain the origin of eukaryotes?
The recent discovery of diverse very large viruses, such as the mimivirus, has fostered a profusion of hypotheses positing that these viruses define a new domain of life together with the three cellular ones (Archaea, Bacteria and Eucarya). It has also been speculated that they have played a key role in the origin of eukaryotes as donors of important genes or even as the structures at the origi...
متن کاملComparison of Vero and MDCK cell lines transfected with human siat7e gene for conversion to suspension culture
Introduction: Inactivated influenza vaccines are traditionally produced in chicken embryonated eggs but its limitations in producing the required doses in pandemic outbreaks quickly enough has made searching for alternative modes of production necessary. The use of cell culture-based vaccine production is one way of overcoming the limitations of the egg-based method and securing a more rapid re...
متن کاملCancer virotherapy: Targeting cancer cells by microRNA mechanism for selective replication of oncolytic viruses in these cells
Cancer, as one of the most serious public health problems, is the second-leading cause of death in the world after cardiovascular disease. The number of patients and the resulting mortality are increasing worldwide; therefore, early diagnosis, prevention, and effective treatment of cancer are very important. Current treatments such as chemotherapy and radiation therapy are often non-selective a...
متن کاملViral Infection at High Magnification: 3D Electron Microscopy Methods to Analyze the Architecture of Infected Cells
As obligate intracellular parasites, viruses need to hijack their cellular hosts and reprogram their machineries in order to replicate their genomes and produce new virions. For the direct visualization of the different steps of a viral life cycle (attachment, entry, replication, assembly and egress) electron microscopy (EM) methods are extremely helpful. While conventional EM has given importa...
متن کاملNeuraminidase gene sequence analysis of avian influenza H9N2 viruses isolated from Iran
Influenza A viruses possesses two virion surface glycoproteins including haemagglutinin (HA) and neuraminidase (NA). The NA plays an important role in viral replication and promotes virus release from infected cells and facilitates virus spread throughout the body. To find out any genomic changes that might be occurred on NA gene of avian influenza circulating viruses, we have genetically analy...
