TANK-binding kinase-1 delineates innate and adaptive immune responses to DNA vaccines. (Prof. Akira and Associate Prof. Ishii in Nature)

DNA vaccines induce adaptive immune responses, mainly through induction of type I interferons. Ken Ishii and colleagues use mice to show that this occurs by a mechanism that is independent of the activation of nucleic-acid-binding Toll-like receptors. Instead, some T-cell responses require activation of the TANK-binding kinase 1 (TBK1)-mediated innate immune signalling pathway in haematopoietic cells. In non-haematopoietic cells, TBK1 is critical for the activation of CD8 T cells. Therefore, in two distinct cellular mechanisms, TBK1 is a key player in DNA-vaccine-induced immunity.
