The bacterial secondary messenger c-di-AMP can be sensed by cytosolic receptors to activate innate immunity. Fan and colleagues show the ER-associated protein ERAdP to be a high-affinity receptor for c-di-AMP, linking it to downstream inflammatory responses.
Klein and colleagues show, in a mouse model of West Nile virus–induced cognitive dysfunction, that neurogenesis is impaired by production of IL-1 from pro-inflammatory astrocytes.
