Study Finds Possible 'Persistence' Switch for Tuberculosis
September 17, 2010
A model for the genetic "persistence" switch that toggles tuberculosis bacteria into a dormant state that resists antibiotics and immune system responses is described in the September issue of the journal Physical Biology. An analysis of stress-response genes in the organism Mycobacterium tuberculosis has allowed Rice University bioengineers Oleg Igoshin and Abhinav Tiwari to zero in on a gene network that appears to help the bacteria ward off attacks.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
