Scientists have developed a new marking system that allows them to visualize and track immune memory cells for the first time. This breakthrough has significant implications for vaccine development, organ transplantation, and the treatment of autoimmune diseases.
Researchers at Northwestern University Medical School have developed a rapid diagnostic test to detect vancomycin-resistant enterococci (VRE), a growing threat to hospital patients. The new method, called hot-start polymerase chain reaction (PCR), detects VRE in 13 of 15 specimens, allowing for early isolation and treatment.
Researchers at the University of Virginia have discovered that fruit flies respond to cocaine in a similar manner as humans, using similar biochemical pathways. This breakthrough may lead to highly specific drugs to treat cocaine addiction, based on genetic and biochemical insights gained from studying the flies.
The study uses genotypic selection to identify a quantitative trait locus (QTL) associated with alcohol consumption in mice. The results provide experimental confirmation of the QTL and suggest that this method can be used to determine genetic susceptibility to alcoholism.
Researchers at Duke University have developed a new approach to gene therapy that uses enzymes to edit faulty genetic messages in living cells. The study, published in Nature Medicine, demonstrates the potential for correcting genetic defects and may lead to treatments for diseases such as sickle cell anemia and AIDS.
