Genomic Analysis Uncovers New Targets for HIV Vaccine

...ly lead to novel targets for vaccines, the primary goal of CHAVI." Two of the polymorphisms found were in genes controlling the human leukocyte antigen (HLA) system, which plays a major role in the immune system by identifying foreign invaders and "tagging" them for destruction. Two of the HLA genes, kn...

One species, many genomes

... How environment and genome interact is also the goal of new, even more powerful methods. While the technology used so far can only identify genes that have changed or are lost relative to the reference genome, direct sequencing of the genome of wild strains will allow the detection of new genes. The pl...
