Nature Microbiology: Call for Papers

Launching in January 2016, Nature Microbiology is now open for submissions and inviting high-quality submissions. The journal will cover all aspects of microorganisms be it their evolution, physiology and cell biology, their interactions with each other, with a host, with an environment, or their societal significance. 

Submit your next research paper to the journal.

Co-ordination of intrathymic self-representation   pp895 - 896
Graham Anderson and William E Jenkinson
doi:10.1038/ni.3251
Intrathymic expression of self antigens is key for central tolerance. RNA-sequencing analysis of tissue-restricted antigens in individual medullary thymic epithelial cells reveals co-ordination in the gene-expression patterns that ensures effective self-representation for the production of self-tolerant T cells.

IL-26 AMPs up the TH17 arsenal   pp897 - 898
Jacob S Lee and Daniel J Cua
doi:10.1038/ni.3256
A previously unknown function for TH17 cell-derived IL-26 as a direct antimicrobial agent and activator of DNA-sensing innate immunity is now reported.

LRRK2 and Nod2 promote lysozyme sorting in Paneth cells   pp898 - 900
Juliana D B Rocha, Michael G Schlossmacher and Dana J Philpott
doi:10.1038/ni.3255
Paneth cell dysfunction has been linked to Crohn's disease. Nod2 and LRRK2, two genetic susceptibility factors for this disease, are now shown to have a role in regulating the sorting of lysozyme in Paneth cells and its secretion into the crypt space and, ultimately, in maintenance of the intestinal barrier.

TCF-1 and LEF-1 help launch the TFH program   pp900 - 901
Masato Kubo
doi:10.1038/ni.3254
Follicular helper T cells (TFH cells) differentiate from naive T cells, but the picture of this differentiation process remains incomplete. Two studies now identify the related transcriptional regulators TCF-1 and LEF-1 as important early participants in this process.

Teaching 'big data' analysis to young immunologists   pp902 - 905
Joachim L Schultze
doi:10.1038/ni.3250
Everyone and everything seems to go 'big data' these days. The task ahead will be to train young immunologists to formulate intelligent hypotheses using big data resources.

Phagocytosis of apoptotic cells in homeostasis   pp907 - 917
Sanja Arandjelovic and Kodi S Ravichandran
doi:10.1038/ni.3253
Billions of cells in the body die through apoptosis every day and are cleared by both professional and non-professional phagocytes. Arandjelovic and Ravichandran review how apoptotic cell clearance is critical for immune homeostasis.

Commensal bacteria direct selective cargo sorting to promote symbiosis   pp918 - 926
Qin Zhang, Ying Pan, Ruiqing Yan, Benhua Zeng, Haifang Wang et al.
doi:10.1038/ni.3233
Mucosal immunity is influenced by commensal bacteria. Liu and colleagues show that commensals direct selective cargo sorting in Paneth cells through the cytosolic sensor NOD2 and the kinase LRRK2 to promote symbiosis.

Antigen-specific NK cell memory in rhesus macaques   pp927 - 932
R Keith Reeves, Haiying Li, Stephanie Jost, Eryn Blass, Hualin Li et al.
doi:10.1038/ni.3227
Recent studies have shown features of antigen-specific memory in mouse NK cells, but it is unclear whether this phenomenon also exists in primates. Barouch and colleagues provide evidence for robust, durable, antigen-specific NK cell memory induced in primates after infection or vaccination.

Single-cell transcriptome analysis reveals coordinated ectopic gene-expression patterns in medullary thymic epithelial cells   pp933 - 941
Philip Brennecke, Alejandro Reyes, Sheena Pinto, Kristin Rattay, Michelle Nguyen et al.
doi:10.1038/ni.3246
How expression of tissue-restricted self-antigens (TRA) is coordinated in medullary thymic epithelial cells (mTECs) remains unclear. Steinmetz and colleagues use single-cell RNA-sequencing to describe clusters of co-expressed TRAs.

Aire controls gene expression in the thymic epithelium with ordered stochasticity   pp942 - 949
Matthew Meredith, David Zemmour, Diane Mathis and Christophe Benoist
doi:10.1038/ni.3247
How expression of tissue-restricted self antigens is coordinated in medullary thymic epithelial cells has remained unclear. Benoist and colleagues use single-cell RNA sequencing to identify clusters of co-expressed tissue-restricted antigens.

The ubiquitin-specific protease USP8 is critical for the development and homeostasis of T cells   pp950 - 960
Almut Dufner, Agnes Kisser, Sandra Niendorf, Anja Basters, Sonja Reissig et al.
doi:10.1038/ni.3230
Post-translational modifications regulate various signaling cascades downstream of the TCR. Knobeloch and colleagues show that the deubiquitinase USP8 is required for thymocyte development by interacting with the adaptor Gads upon TCR stimulation.

T cell receptor dwell times control the kinase activity of Zap70   pp961 - 969
Christian Klammt, Lucie Novotná, Dongyang T Li, Miriam Wolf, Amy Blount et al.
doi:10.1038/ni.3231
Recruitment of the kinase Zap70 to the T cell receptor (TCR) is essential for signal transduction. Lillemeier and colleagues show that the conformation of Zap70 controls TCR dwell time, which in turn controls Zap70 activity.

TH17 cells promote microbial killing and innate immune sensing of DNA via interleukin 26   pp970 - 979
Stephan Meller, Jeremy Di Domizio, Kui S Voo, Heike C Friedrich, Georgios Chamilos et al.
doi:10.1038/ni.3211
TH17 cells have important roles at mucosal surfaces in both health and disease. Gilliet and colleagues show that IL-26 is preferentially produced by human TH17 cells and that this cytokine has both alarmin and direct antimicrobial functions.

LEF-1 and TCF-1 orchestrate TFH differentiation by regulating differentiation circuits upstream of the transcriptional repressor Bcl6   pp980 - 990
Youn Soo Choi, Jodi A Gullicksrud, Shaojun Xing, Zhouhao Zeng, Qiang Shan et al.
doi:10.1038/ni.3226
Follicular helper T cells (TFH cells) are specialized effector CD4+ T cells that help B cells develop germinal centers and memory. Crotty and colleagues show that the transcription factors LEF-1 and TCF-1 are required for early TFH differentiation.

The transcription factor TCF-1 initiates the differentiation of TFH cells during acute viral infection   pp991 - 999
Lifan Xu, Yi Cao, Zhunyi Xie, Qizhao Huang, Qiang Bai et al.
doi:10.1038/ni.3229
Follicular helper T cells (TFH cells) require the transcription factor Bcl-6 and are antagonized by the transcription factor Blimp1 (encoded by Prdm1). Lilin Ye and colleagues show that acute viral infection induces the transcription factor TCF-1, which promotes TFH differentiation by enhancing Bcl6 expression while suppressing that of Prdm1.
