Sentences with phrase «host cell processes»

These toxins manipulate host cell processes to create optimal growth conditions for the bacteria in hiding.

Not exact matches

That is, they depend on the host cell for the raw materials and energy necessary for nucleic acid synthesis, protein synthesis, processing and transport, and all other biochemical activities that allow the virus to multiply and spread.

Combing the genetic data from a transmission study in ferrets, a team led by Thomas Friedrich, a professor of pathobiological sciences at the University of Wisconsin - Madison School of Veterinary Medicine, found that during transmission, when one animal is infected by another through sneezing or coughing, the process of natural selection acts strongly on hemagglutinin, the structure the virus uses to attach to and infect host cells.

The new study shows that the synthetic compound is capable of inhibiting the activities of several DNA - processing enzymes, including the «integrase» used by the Human Immunodeficiency Virus (HIV) to insert its genome into that of its host cell.

Viruses can't survive without a host, and the most - studied viruses linked to disease are lytic in nature: They get inside a cell and make copies of themselves, destroying the cell in the process.

In particular, they have examined the ways in which viruses hijack cell proteins to help regulate their exit and spread from the host cell through the budding process.

They seem most lifelike only when they invade and co-opt the machinery of living cells in order to make more of themselves, often killing their hosts in the process.

That viral DNA is then directly spliced into the host cell's DNA and passed along with the cell's natural replication process.

Once the viral RNA is transcribed, HCV initiates a process known as IRES - mediated translation, which allows the viral RNA to be translated into proteins by bypassing certain protein translation checkpoints that would normally be required by the host cell to start protein translation.

This process enables the virus to take advantage of the host cell's protein translation machinery for its own purposes.

The prM cleavage process is important for new viral particles to be able to infect a host cell.

Researchers from Melbourne's Walter and Eliza Hall Institute have discovered how a common parasite hijacks host cells and stockpiles food so it can lie dormant for decades, possibly changing its host's behavior or personality in the process.

Melbourne researchers have discovered how a common parasite hijacks host cells and stockpiles food so it can lie dormant for decades, possibly changing its host's behaviour or personality in the process.

Their findings — that nanotubes and vesicles are an important part of the communications process — show that the extracellular vesicles contribute to the complexity of African trypanosomiasis through the transfer of virulence factors between parasites and inadvertent interaction with host cells, which has a profound effect on disease, the study notes.

Sepsis, Drs. Tracey and Deutschman wrote, «is not a stereotypical, steadily progressive immunological process that follows infection or injury; that innate and adaptive immune responses do not inevitably damage host cells; and that the long - held notion that sepsis is a distinct immunological disorder is incorrect.

Animal cloning uses a process known as somatic - cell nuclear transfer, where the nucleus from an adult (donor) cell is transferred into an egg (host) cell lacking a nucleus.

This resulted in a staggering 50,000 virus - host protein interactions, approximately 500 of which appeared to be involved in viral infection.By removing the interacting host proteins from the cell one at a time, the researchers were able to determine what their functional contribution was in the infection process: whether the host proteins were hijacked by the virus and used to spread infection, or whether they were part of a defense mechanism against the virus.

This must be accomplished by using a process known as germ - line transmission, where the primordial germ cells (PGCs) of an early embryo are edited, grown in cultures, and then reproductively transmitted through surrogate host parents to generate live, engineered birds.

Providing rigidity to the cell, actin filaments are involved in a host of processes including muscle contraction, cell mobility and cell division.

LA JOLLA, CA — When the body is under attack from pathogens, the immune system marshals a diverse collection of immune cells to work together in a tightly orchestrated process and defend the host against the intruders.

By playing with the protein, they showed that the virus could be switched on or off separate from the rhythms of its host immune cell, indicating that the two processes were independent of one another.

A host of endocytic processes has been described at the plasma membrane of eukaryotic cells.

This multi-stage process requires tumour cells to survive in the circulation, extravasate at distant sites, then proliferate; it involves contributions from both the tumour cell and tumour microenvironment («host», which includes stromal cells and the immune system).

While erythrocyte invasion is a rapid process, the brief extracellular exposure of merozoites outside of their intra-erythrocytic niche places them in direct contact with host antibodies, which contribute to naturally acquired immunity to malaria [8, 9]; therefore, merozoite cell surface and secreted proteins have long been considered attractive targets for rational vaccine development.
