Katherine Xue studies how the flu evolves inside you
The recipient of the 2018 Crow Award reveals details of flu evolution at the smallest —and largest—scales. For many viral diseases, a vaccine can provide lifelong protection. But for flu, you need a new shot every year. The influenza virus evolves so fast it presents a constantly moving target for both our immune systems and…

Enhancing our view of enhancers
GC content alone is associated with distinct functional classes of human enhancers. Because enhancers can be located hundreds of kilobases away from their target genes, it can be challenging to accurately predict their functions. A new report in GENETICS uses sequence composition to distinguish two enhancer classes that have distinct functions and spatial organization in humans.…

How baker’s yeast turns from friend to foe
Beer, doughnuts, and genetics textbooks have one thing in common: they were all made possible by collaborations between humans and yeast. Our fungal ally Saccharomyces cerevisiae resides not only in breweries, bakeries, and laboratories, but also sometimes in our own bodies—where, on rare occasions, it betrays us. S. cerevisiae is increasingly being reported as an…

An overactive immune system alters the gut microbiome in Drosophila
Taking probiotics might be the latest health fad, but for people with inflammatory bowel diseases, the microbiome is a more serious matter. With these autoimmune diseases, the composition of the gut microbiome can have critical health consequences. In the June issue of GENETICS, Mistry et al. use fruit flies to determine whether immune system activity…

Rapid immune evolution: exception or rule?
The arms race between pathogens and their hosts leaves clear genetic marks: the most quickly evolving parts of host genomes often include immune genes. But are these fast-movers the exception among immune genes, or do most genes in this class bear the genetic signature of strong selection? In the January issue of GENETICS, Early et…

Cover contest: Immune Repertoires
In 2014, the GSA journals launched a contest inviting image submissions related to genetics and genomics. The winning entry was created by Jian Han, of the HudsonAlpha Institute for Biotechnology, and appears on the cover of the May 2015 issue of G3. We talked with Dr. Han about the striking image: What does the image…

The trouble with HLA diversity
The most diverse of all human genes encode a set of proteins at the frontline of our immune system. Many different Human Leukocyte Antigen (HLA) proteins are encoded by genes clumped together in one portion of the human genome known as the major histocompatibility complex region. HLA proteins sit on the surface of cells and…

Frog immune responses to a global threat
Dramatic global declines in amphibians have been linked to the fungal pathogen Batrachochytrium dendrobatidis, but some species are more vulnerable than others. In the latest issue of G3: Genes|Genomes|Genetics, as part of the GSA Journals’ Genetics of Immunity collection, Ellison et al. examined the transcriptome of the highly susceptible Panama Golden Frog after exposure to…

Turning to the Worm
When Scott Alper and colleagues looked for candidate regulators of mammalian innate immunity based on gene expression data, the hit rate was only around 2%. By using a comparative genomics approach — starting with an RNAi screen in Caenorhabditis elegans — their hit rate rose to nearly 30%. In a new GENETICS article, published as…

Sea Anemone & Friends
Coral reefs around the world are “bleaching”, a threat caused by breakdown of the symbiosis between the coral animals (cnidaria) and the dinoflagellate algae that live within their cells. Yet this crucial symbiotic partnership is poorly understood. To address this knowledge gap, biologists are developing a suite of genomic tools for the sea anemone Aiptasia. This…
