Genomic Analysis Uncovers New Targets for HIV Vaccine

DURHAM, N.C. – An international team of researchers has identified three gene variants in the DNA of 486 people infected with HIV that appear to have helped some of the patients fight off the virus and delay the onset of full-blown AIDS. The researchers expect the new findings to aid t...

Scratch no more: Gene for itch sensation discovered

...or in the spinal cord until now." In fact, Chen's team became interested in GRPR because they were looking for genes in the pain pathway. Among potential pain-sensing genes they identified, GRPR stood out because it is present in only a few nerve cells in the spinal cord known to relay pain and/or itch s...

Cells re-energize to come back from the brink of death

...asses CICD as well,” Green said. The St. Jude team discovered that a cell that lacks caspase activation and cannot undergo apoptosis increases the levels of an enzyme called GAPDH in order to counteract CICD. GAPDH appears to prevent CICD by supporting the functioning of the mitochondria and triggeri...

A new plant-bacterial symbiotic mechanism promising for crop applications

...e zones, very little those of the tropics. The team from the IRD’s ‘Laboratoire des Symbioses Tropicales et Méditerranéennes’ and its partners (1), taking as model a symbiosis between a tropical aquatic legume, Aeschynomene, and Bradyrhizobium, bacteria of the Rhizobia family, have just revealed a new...

The team screened the DNA from 1,400 individuals who had been clinically assessed with Alzheimer’s prior death, and simultaneously examined more than 500,000 SNPs or genetic variations to characterize and confirm additional LOAD susceptibility genes. The sear...
