This week’s articles identify a potential cause for the development of celiac disease and a method for targeting an AMPA receptor agonist to specific neurons.
IMMUNOLOGY
Viruses compound dietary pathology
Bouziat et al. found that a nonpathogenic virus can promote inflammatory immunity to dietary antigens and may be linked to the development of celiac disease (see also Verdu and Caminero).
NEUROSCIENCE
A tailored look at behavioral pharmacology
Shields et al. developed a technique, DART (Drugs Acutely Restricted by Tethering), that rapidly localizes drugs to the surface of specific neurons.
