Featured Paper: Allergy the Price of Immunity

We would like to draw your attention to a paper recently published in PLOS Computational Biology: Comparisons of Allergenic and Metazoan Parasite Proteins: Allergy the Price of Immunity by Nidhi Tyagi, et. al.

It is thought that part of our immune system has evolved to combat and provide immunity against infection by parasitic worms. However, in the absence of parasitic infection, this same arm of the immune system can become hyper-responsive and mistakenly target allergenic proteins in food or the environment. This results in an unregulated allergic response, which can sometimes be lethal.

The researchers used computational techniques to predict which proteins in parasitic worms would cause an immune response similar to an allergic reaction in humans. Their experimental studies supported these predictions and, for the first time, they identified a protein in a parasitic worm that is similar to a protein that was previously thought to be encoded only in the genomes of plants. This protein is one of the most common proteins in pollen that causes allergy in humans.

The paper and its associated Brugia malayi and Onchocerca volvulus genes are part of the WS252 release of WormBase.

Introductory chapter added to WormBook

Dear WormBook reader,

We are very happy to announce that A Transparent Window into Biology: A Primer on Caenorhabditis elegans, by Ann Corsi, Bruce Wightman, and Marty Chalfie, has just been added to WormBook as a co-publication with GENETICS. This concise and comprehensive review, which serves as an introductory chapter to WormBook, discusses the basic biology, genetics, anatomy, genomics, ecology, and evolution of C. elegans. Key discoveries resulting from research using this organism are described, as is the strong collaborative nature of the worm community. We expect this introduction to provide an invaluable resource for students and others new to C. elegans research and literature.

We thank Tracey DePellegrin, Ruth Isaacson, and Elizabeth De Stasio of GENETICS for their dedication to this collaboration, as well as Editor-in-Chief Mark Johnston for his support of the project.

Nuclear receptor chapter updated in WormBook

Nuclear receptor signal transduction in C. elegans, by Adam Antebi, has just been published in the Signal transduction section of WormBook. This chapter updates his 2006 chapter, Nuclear hormone receptors in C. elegans. The updated chapter discusses the role of nuclear receptors as regulators of life history, cell fate, and organogenesis, and their function in nutrient sensing, metabolism and energy homeostasis.
