TCF19 drives a broad transcriptional program that potentiates optimal innate and adaptive functions of antiviral NK cells
Natural killer (NK) cells are innate lymphocytes that play a critical role in host defense against viral infection. In addition to rapid effector cytokine production and direct cytotoxicity, NK cells exhibit features of adaptive immunity, including the capacity to undergo robust antigen-specific clonal proliferation and to generate immunological memory1–3. However, the transcriptional programs and regulators governing dynamic NK cell responses to viral infection have not been fully uncovered. In this study, we identified transcription factor 19 (TCF19) as a key driver of NK cell proliferation and calcium signaling in the context of mouse cytomegalovirus infection. Ablation of TCF19 was detrimental to NK cell clonal expansion and host protection against viral infection. Tcf19−/− NK cells were also unable to properly mobilize calcium downstream of antigen signaling to mediate cytotoxicity. Altogether, we find that TCF19 drives a transcriptional program that coordinates the innate and adaptive NK cell responses against viral infection. Sun and colleagues report that the transcription factor TCF19 regulates calcium signaling and cell cycling progression in NK cells and is required for innate and adaptive NK cell responses to viral infection.
期刊介绍:
Nature Immunology is a monthly journal that publishes the highest quality research in all areas of immunology. The editorial decisions are made by a team of full-time professional editors. The journal prioritizes work that provides translational and/or fundamental insight into the workings of the immune system. It covers a wide range of topics including innate immunity and inflammation, development, immune receptors, signaling and apoptosis, antigen presentation, gene regulation and recombination, cellular and systemic immunity, vaccines, immune tolerance, autoimmunity, tumor immunology, and microbial immunopathology. In addition to publishing significant original research, Nature Immunology also includes comments, News and Views, research highlights, matters arising from readers, and reviews of the literature. The journal serves as a major conduit of top-quality information for the immunology community.
