UCLA researchers find cell protein that literally nips HIV in the bud
01-11-2008 · EurekAlert!UCLA researchers have found that a key protein in the body's dendritic cells can stop the virus that causes AIDS from "budding" -- part of the virus' life cycle that is crucial to its ability to replicate and infect other cells.

- UF researchers track genetic journey of HIV from birth to death
10-16-2007 · EurekAlert!
University of Florida researchers tracked four children born with HIV, studying blood samples taken at birth, throughout life and just after death. Using a high-resolution computational technique, they monitored protein mutations. Previous studies relied on cell culture or animal models to follow the virus' mutations over time. The UF researchers are among the first groups to study the progression of HIV in human patients.

- Researchers reveal HIV peptide's possible pathway into the cell
01-17-2008 · EurekAlert!
Two theoretical physicists at Rensselaer Polytechnic Institute have uncovered what they believe is the long-sought-after pathway that an HIV peptide takes to enter healthy cells. The theorists analyzed two years of biocomputation and simulation to uncover a surprisingly simple mechanism describing how this protein fragment penetrates the cell membrane. The discovery could help scientists treat other human illnesses by exploiting the same molecules that make HIV so deadly proficient.

- New weapon to fight leukemia
08-23-2007 · EurekAlert!
A new study indicates that the drug FTY720 prevents disease in a mouse model of two leukemias -- blast crisis chronic myeloid leukemia and acute lymphocytic leukemia -- caused by the cancer protein BCR-ABL. As the drug also induced cell lines from humans with these leukemias to die in vitro the authors suggest that FTY720 should be considered by researchers and clinicians developing new approaches to treat CML-BC and ALL.

- Cilia: small organelles, big decisions
10-03-2007 · EurekAlert!
Johns Hopkins researchers say they have figured out how human and all animal cells tune in to a key signal, one that literally transmits the instructions that shape their final bodies. It turns out the cells assemble their own little radio antenna on their surfaces to help them relay the proper signal to the developmental proteins "listening" on the inside of the cell.

02-04-2008 · EurekAlert!
There's new hope for breast cancer research, and it's coming from a very unlikely place. Researchers at the Texas A&M University College of Veterinary Medicine & Biomedical Sciences recently published articles in the journals Molecular and Cellular Biology and Carcinogenesis indicating that a protein long suspected to play a role in Down Syndrome may also contribute to treating this devastating disease.

- Gene Key To Taste Bud Development Identified
10-02-2006 · ScienceDaily
Scientists have identified a gene that controls the development of taste buds. The gene, SOX2, stimulates stem cells on the surface of the embryonic tongue and in the back of the mouth to transform into taste buds, according to the researchers. Stem cells are immature cells that can develop into several different cell types depending on what biochemical instructions they receive.

- Single protein can determine severity of toxoplasma infections
12-20-2006 · EurekAlert!
Now, a team of Stanford University School of Medicine researchers, led by John Boothroyd, PhD, has shown for the first time how toxoplasma manages to be so effective: They documented how it injects a particular protein into the cell it infects and how that protein then travels to the cell's nucleus -- where it blocks the cell's normal response to invasion.
