| Unraveling biological networks: Biological network motif discovery algorithms Posted: 05 Mar 2012 10:25 AM PST A new approach to disentangling the complexities of biological networks, such as the way in which proteins interact in our body's cells has been developed. The new algorithm could allow biologists and biomedical researchers to unravel new clues about how cells work and what goes awry with such networks in various diseases, such as Alzheimer's disease and cancer.  |
| Will a genetic mutation cause trouble? Ask Spliceman Posted: 05 Mar 2012 10:24 AM PST New, free Web-based software analyzes DNA sequences to determine if mutations are likely to cause errors in splicing of messenger RNA. When gene splicing goes awry, a wide variety of diseases can result.  |
| Skin infection sheds light on immune cells living in our skin Posted: 29 Feb 2012 11:21 AM PST Very recently, researchers discovered an important population of immune cells called memory T cells living in parts of the body that are in contact with the environment (e.g., skin, lung, GI tract). How these "resident" memory T cells are generated was unknown, and their importance with regard to how our immune system remembers infection and how it prevents against re-infection is being studied intensively. A new study has used a vaccinia virus infection to answer important questions about how these newly discovered cells protect us.  |
