UCLA scientists transform HIV into cancer-seeking missile

... for therapeutic genes that can travel through the blood and aim itself at a precise location, thereby minimizing harmful side effects," explained Irvin S.Y. Chen, Ph.D., director of the UCLA AIDS Institute. "Our approach proves that it is possible to develop an effective carrier and reprogram it to target...

New insight into people who 'see' colors in letters and numbers

No home-use test kits intended for diagnosing syphilis and dengue fever are approved for sale in the U.S. The FDA has issued an import alert which alerts FDA field perso...

Scientists identify new model Of NK cell development

...rrow progenitor cells and 6 percent of circulating blood progenitor cells, they comprise virtually all of the progenitor cells found in lymph nodes. Interestingly, Gerard Nuovo, a pathologist and co-author of the study, discovered that these novel NK precursor cells are not randomly strewn throughout the ...

White blood cell waste disposal system plays critical regulatory role

...ritical immune cells. Human neutrophils are white blood cells that are constantly being produced in the bone marrow and released into the blood stream where they migrate out of the blood and roam the body in search of potentially harmful foreig...

TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas

...cytes) multiply uncontrollably and crowd out other blood cells. The St. Jude researchers report that TEL2 cooperates with MYC to increase the chance that a certain mutation will occur in precancerous B lymphocytes, permitting these cells to become cancerous. This mutation inactivates the function of p53, a...

He and Dudley are applying for grants to do a more systematic survey to see how common gliding is among the hundreds of species of canopy ants as well as other insects that live in the trees, and to explore the biomechanics of their glidin...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...ack, and the disease makes it difficult to control blood sugar levels in people with diabetes. If that’s not bad enough, pregnant women with periodontal disease are seven times more likely to deliver low-birth-weight, preterm babies. Proteins are important to study because they are the foundation of the ce...

New Treatment Rivals Chemotherapy For Lymphoma, Study Finds
