Pyrimidine synthesis enzyme CTP synthetase 1 suppresses antiviral interferon induction by deamidating IRF3
The intersection between cellular metabolism and innate immunity lacks understanding. Here, Rao and Qin et al. report that the metabolic enzyme, CTP synthetase 1, deamidates IRF3 to limit interferon induction, independent of its role in pyrimidine synthesis. This reveals how a key metabolic enzyme directly regulates innate immune activation.

Lymph node swelling is a well-known symptom of infection. A shift in the chemoattractant code controls lymphocyte recruitment from blood into inflamed lymph nodes, allowing lymphocytes to accumulate so that even rare antigen-specific cells can encounter their activating antigen.
