Genomic and Genetic Insight into Gut Microbiota Function and Manipulation

submitted by: dougramsey
Trillions of microbes live in our digestive tract and influence our biology in profound and diverse ways. Several diseases, including obesity and inflammatory bowel diseases, have been associated with large-scale shifts in microbiota composition. The ability to address basic questions concerning community function and plasticity are fundamental to understanding the extent of causal relationships between host biology and microbiota perturbations, and whether the microbiota is a viable...

TGFß & Alzheimer's Disease

submitted by: alex01

R.A. Flavell (Yale University, New Haven, CT) discusses the role of Transforming Growth Factor ß (TGFß) in disease. In the central nervous system of a murine model of AD this cytokine appears to prevent macrophages from attacking ß-amyloid. Flavell visualizes that selective blockade of this TGFß
activity could lead to the destruction of plaques in patients with AD.
