Sentences with phrase «than host cells»

It indicates that the interaction with mitochondria is driven by Toxoplasma, rather than the host cell, and it is likely something the parasite does «to enable survival in some particular subset of hosts,» he says.

Not exact matches

I care about the life people like you are attempting to force in to this world, you care about what appeases your god - big difference when you really don't care or consider the child only what your imaginary friend god wants and yet your god cause abortions all the time... you care about a clump of cells, not the actual life of the child and that's much worse than me supporting the rights of a woman to have control over her body, especially if the clump of cells couldn't survive outside of the host.

Individual cells within a complex organism, to be sure, apparently have a shorter life - span than their host.

A host can often be infected with more than one type of virus and, as viruses replicate in the host's cells, the genetic segments of the progeny viruses can be shuffled into new combinations.

The 1917 virus had infection and mortality rates typical of seasonal flu, but a single mutation in the proteins affecting how the virus binds to a host cell may have led to the deadly 1918 wave, which killed more than 50 million people worldwide.

With more - than -30-year-old frozen tissues from a preserved frog, the team extracted and implanted the nucleus of a dead cell into a fresh host egg from a distantly related species.

Because this approach jams the host cell machinery rather than directly attacking the bacteria, the chances of bacteria developing resistance could be very low, say the researchers.

RNA vaccines are appealing because they induce host cells to produce many copies of the proteins they encode, which provokes a stronger immune reaction than if the proteins were given on their own.

Nevertheless, they discovered that groups of viruses that were farther from the host cell were more mature than those closer to it, which suggested that the host cell releases new virus in a series of «semi-synchronized» waves.

That suggests that the damage done to the lungs is the result of an overreaction of the host, rather than the virus killing cells, Kash says.

That approach, which shuts down the hyperactive donor T cells when they first arrive, has not only allowed patients to tolerate grafts from increasingly mismatched hosts but, in several recent studies, has also cut rates of severe acute and chronic GVHD to less than 15 %.

As an example of a disease whose genetic basis not only is felt to be much simpler than that of malignancies, but also is affected by host genomic and environmental complexities, consider sickle cell disease.

In spite of mismatching, cord blood cells cause less graft versus host disease (GVHD) than adult cells.

This strategy seeks to preserve rather than restore host tissue function by taking advantage of unique properties often displayed by these versatile cells.

Indeed, the body hosts more microbial hitchhikers than it does human cells.

Further challenges include the identification of signaling molecules that promote the generation of beneficial populations of astrocytes, identification of appropriate stem and / or progenitor cell populations that can be the source of such cells, and determination of whether there are situations in which it is more useful to transplant astrocytes themselves rather than to transplant stem or progenitor cells that might generate astrocytes in vivo in response to signals present in the host environment.

For more than a decade, Ralf F. W. Bartenschlager (University of Heidelberg) and Charles M. Rice (Rockefeller University) attempted to coax the hepatitis C virus (HCV) to multiply inside lab - grown host cells.

That's more bacterial cells in the host than actual DNA - containing cells!

A. Bacteria: completely independent, able to eat and reproduce quickly (can develop into millions of cells in 4 hours) B. Virus: 1/1000 smaller than a bacterial cell, not alive, attaches to a host cell and injects its material into that cell and uses the genetic material to make new viruses - the host cell bursts and releases the viruses C. Parasites:

Did you know that we host more foreign bacteria than cells in our bodies?

Human cells are much larger than the millions of guest cells that we host, and the 25 - foot adult intestinal tract is home to billions of microorganisms — both friendly and not - so - friendly.

Cell samples are collected from the dog to be cloned, preferably from a live host or one that has been dead for no more than five days.

However, rather than overcoming the infection, these cells become the hosts for the FIV virus.

«Our technology will provide significantly higher forces and faster impact cycles than have previously been possible, and by building these tools onto microfluidic devices, we can leverage a host of other on - chip diagnostics and imaging tools and can collect the cells after testing for longer - term studies,» said Valentine.
