DNA to the defense

...they contain 'contingency genes' that the parasite multiplies and diversifies for future use." In previous studies, Melville's group showed that trypanosome chromosomes were quite variable in size. "The range of size variation we observe in African trypanosomes far exceeds anything reported in other organism...

Breaks in hibernation help fight bugs

... is cold. For animals exposed to Salmonella, which multiplies rapidly in warm temperature, a regular break in hibernation would be an important adaptation to combat the germs, when experiencing a warmer winter. However, Salmonella doesn't thrive at very low temperatures, so when animals experience a particularl...

African parasite makes component of fat differently from all other organisms

... such form is harbored by the insect and the other multiplies in a host's bloodstream. There, the parasite avoids detection by the human immune system by replacing each of the 10 million proteins on its outer layer - known as the cell membrane - with different proteins that are not recognized by immune cells....

Human albumin from tobacco plants

... plant, while application of the plastidial system multiplies this percentage by fourteen (to 7%), reaching an average of 0.9 milligrams of HSA per gram of fresh leaf weight. The key is the place where the gene in question is deposited. With the nuclear transformation method, it integrates into the DNA of the...

Researchers discover how malaria parasite disperses from red blood cells

...life when it infects red blood cells, the parasite multiplies inside the cell, until the cell ruptures and releases them. The newly released merozoites infect still other cells, and the process begins again. To conduct the study, the researchers stained red blood cells infected with P. falciparum with two k...

UIC developing drug for SARS

...ameliorate the disease." Like HIV, the SARS virus multiplies rapidly, hijacking the machinery of the cells it infects to clone itself over and over again. One of the first steps in that process is the production of a long chain of proteins, all of which are needed for the virus to propagate. Two enzymes, or p...

Recombinant DNA technology may enable oral, rather than injectable, delivery of protein drugs

... put into cell culture, a recombinant DNA molecule multiplies itself to form a colony of daughter cells that secretes the desired protein. These cells become "factories" for the production of the protein coded for by the inserted DNA. As it turned out, this was the case as well for the transferrin/G-CSF combin...

Scientists discover that host cell lipids facilitate bacterial movement

...cell, causing the cell to ingest it. The bacterium multiplies inside the cell and then uses a cellular protein called ActA to stimulate the host cell's actin to form filaments at one end of the bacterium. "As these filaments lengthen, they drive the bacterium through the cell until it reaches the peripheral or...
