Anthrax: pre-publication and special issue
Recent events have confirmed that bioterrorism is no longer a threat but a reality. To provide wide-ranging access to the latest scientific information about anthrax and other potential bioweapons, Nature has put together a special online focus on this issue. This focus includes the pre-publication* of two research papers on anthrax toxin, as well as a collection of research, news and feature articles from our electronic archive. Because of the heightened interest in this area, among both the scientific community and the general public, all material in this feature has been made freely available.
The causative agent of the anthrax disease, the bacterium Bacillus anthracis, secretes a toxin made up of three proteins: protective antigen (PA), oedema factor (OF) and lethal factor (LF). PA binds to cell-surface receptors on the host’s cell membranes. After being cleaved by a protease, PA binds to the two toxic enzymes, OF and LA, and mediates their transportation into the cytosol where they exert their pathogenic effects.
In the first of our pre-published papers, Bradley et al. report the cloning of the human PA receptor using a genetic complementation approach. The receptor, named anthrax toxin receptor, is a type I membrane protein with an extracellular Von Willebrand factor A domain that binds directly to PA. In the other paper, Pannifer et al. describe the crystal structure of lethal factor — the crucial pathogenic enzyme of anthrax toxin — which cleaves members of the mitogen-activated protein kinase kinase (MAPKK) family and disrupts cellular signalling. As both PA and LF are possible targets for therapeutic agents, these papers provide valuable information to researchers working towards better treatments for anthrax.
In addition to these Nature papers, this special focus also includes research from October’s issue of Nature Biotechnology. Mourez et al. describe the isolation of a synthetic peptide that blocks the action of anthrax toxin in an animal model. These research papers are complimented by a news feature which looks at the threat of bioterrorism and researchers’ attempts to counter it, and a collection of research, news and opinion articles from our archive. Our final featured article is a timely ’Advanced Online Publication’ from Nature Genetics. Claire Fraser (President of The Institute of Genomic Research) and Malcolm Dando (Professor of International Security, Department of Peace Studies, University of Bradford, UK) argue in a Commentary article that the biomedical community have a crucial role to play in preventing the use of genomics research in bioweapons manufacture.
Nature’s news and science-writing teams will continue to inform and explain the science behind current events as and when it happens, and this page will be updated accordingly.

Iraq crisis spurs new bioweapons moves
Lack of provision in the Biological Weapons Convention for monitoring and verifying compliance has long been a worry. But negotiations for such provision have been given new momentum by recent events in Iraq.

A call to arms
Biologists should involve themselves in the debate over biological weapons — both to ensure that we have the means to counter the threats that such weapons pose and to help keep those threats in perspective.

Lessons from Iraq on bioweapons
There are strong political pressures to relax the scrutiny of suspected biological weapons activity in Iraq. But the experience of United Nations inspectors in the country points to significant dangers in such a policy.

*Citing advance online publications
This feature includes papers which have published ahead of print using digital object identifiers (DOIs). This allows the papers to be cited before final pagination and print publication. We recommend that you cite these papers by simply adding the DOI to the end of your normal citation:
Pannifer, A., et al. Crystal structure of the anthrax lethal factor. Nature DOI:10.1038/n35101998
After print publication you may use the traditional print citation, but the DOI citation will remain valid as the DOI is a persistent identifier.
