Scientists from the Antwerp Institute of Tropical Medicine, Antwerp University Hospital and Antwerp University have tested a new 'therapeutic vaccine' against HIV on volunteers. The participants were so to say vaccinated with their own cells. The researchers filtered certain white blood cells out of the volunteer's blood, 'loaded' them outside the body and then gave them back. The immune system of the testees was better than before in attacking and suppressing the virus, the scientists reported in the top journal AIDS. But they still cannot cure the disease. http://medicalxpress.com/news/2012-02-hiv-vaccine-people.html HIV & AIDS Mon, 13 Feb 2012 11:19:26 EST news248354335 Gene expression is the process of converting the genetic information encoded in DNA into a final gene product such as a protein or any of several types of RNA. Scientists have long thought that the gene programs regulated by different physiological processes throughout the body are robustly pre-determined and relatively fixed for every specialized cell. But a new study by researchers from the University of California, San Diego School of Medicine reveals the unsuspected plasticity of some of these gene expression programs. http://medicalxpress.com/news/2011-05-plasticity-hormonal-response-rapid-gene.html Genetics Sun, 15 May 2011 13:00:05 EST news224506358
