Sleepless for science: Flies show link between sleep, immune system in Stanford study

... said David Schneider, PhD, assistant professor of microbiology and immunology. "Disrupting sleep in turn disrupts the immune system, which makes them even more infected and it's downhill from there in a 'spiral of death.'" Schneider is the senior author of a study on the sleep patterns of flies that will be publ...

Jefferson scientists find rabies-based vaccine could be effective against HIV

...disease. Matthias Schnell, Ph.D., professor of microbiology and immunology at Jefferson Medical College of Thomas Jefferson University, and his co-workers tested the effects of inserting two different viral proteins into the rabies virus genome, and using such viruses-based vaccines in preventing disease in r...

Gene therapy for blindness clears hurdle in mice

..., an assistant professor of molecular genetics and microbiology in the UF College of Medicine. "We work with rhodopsin, which is the main retinal protein. Without it, or if it is mutated, people simply won’t see." Mutated forms of the rhodopsin produce a toxic protein in the retina that kills cells that receiv...

Cheaper, better disease treatments expected from faster approach to developing antibodies

...biomedical engineering, and molecular genetics and microbiology shaves weeks off the production process. Based on the method's early success, Georgiou has begun a collaboration to identify antibodies to treat arthritis and asthma. In Georgiou's E-clonal antibody method, an antibody that is produced by an E. c...

Jefferson researchers' discovery may change thinking on how viruses invade the brain

...According to Matthias Schnell, Ph.D., professor of microbiology and immunology at Jefferson Medical College of Thomas Jefferson University, viruses such as rabies must be actively transported to the brain and central nervous system. The LC8 protein was thought to tether viruses to the cellular transport machinery...

Antibiotic inhibits cancer gene activity

...rei Gartel, assistant professor of medicine and of microbiology and immunology at UIC and principal investigator on the study. The FoxM1 gene is responsible for turning on genes needed for cell proliferation and turning off genes that block proliferation. Uncontrolled proliferation is characteristic of cancer c...

MRSA toxin acquitted: Study clears suspected key to severe bacterial illness

...He adds, "We routinely receive calls from clinical microbiology laboratories asking to test for the presence of PVL, and it is hard to dissuade them that the PVL results will not affect patient care. Hopefully, the robust and contrary findings in our study provide the experimental evidence to convince the staphyl...

Plants give up answers in the war on bacteria

...a professor of plant biology, plant pathology, and microbiology and molecular genetics. "It's very frustrating. How does this little thing do such great damage to plants?" But this summer, Maeli Melotto, a research associate, and Bill Underwood, a graduate student, in He's laboratory, shed light on the behavior...

Particle size matters to bacteria ability to immobilize heavy metals

...irst study by any group that couples environmental microbiology and nano-mineralogy. "This adds to our understanding of how nanoparticles might influence the environment and contaminant metal mobility in our rivers, lakes and other surface waters, as well as groundwater," said Bose. He will present the resear...

Stanford discovery may help predict when toxoplasma can be deadly

...y a team led by John Boothroyd, PhD, professor of microbiology and immunology. Working with mice, the researchers identified two genes that produce two proteins that Toxoplasma introduces into the cells of the host it infects. What's more, the researchers showed for the first time that certain changes in eit...

Gene therapy for hereditary lung disease advances
