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.

Genomics is rapidly advancing precision medicine for immunological disorders   pp1001 - 1004
Yu Zhang, Helen C Su and Michael J Lenardo
doi:10.1038/ni.3275
Advances in human genomics, when validated functionally, can lead to new insights into how the immune system works. Notably, previously unknown mechanisms revealed by genomics can lead to the development of precision medicine unanticipated on the basis of phenotype alone.

Subversion of anticancer immunosurveillance by radiotherapy   pp1005 - 1007
Laurence Zitvogel and Guido Kroemer
doi:10.1038/ni.3236
Paradoxically, radiotherapy can reinforce immunosuppressive pathways that undermine anticancer immunosurveillance and treatment efficacy. Irradiation induces Langerhans cells to migrate from the skin to lymph nodes, where they stimulate regulatory T cells.

To κ+ B or not to κ+ B   pp1007 - 1009
Megan R Fisher and Craig H Bassing
doi:10.1038/ni.3277
Immature B lymphocytes and T lymphocytes assemble antigen receptor-encoding genes in lineage- and developmental stage-specific fashion. New findings show that pre-B cells use specialized locus-specific epigenetic mechanisms to promote recombination of the locus encoding the immunoglobulin κ-chain (Igk) and κ-chain+ B cell development.

Reading the fine print: sequence-specific activation of cGAS   pp1009 - 1010
Jessica J Chiang and Michaela U Gack
doi:10.1038/ni.3274
A unique guanosine-flanked Y-form DNA triggers innate cGAS-dependent responses that lead to upregulation of the production of type I interferons.

ILC development: TCF-1 reporting in   pp1011 - 1012
Jonathan Kaye
doi:10.1038/ni.3276
The transcriptional regulator TCF-1 marks rare progenitor cells in adult bone marrow that have lost the potential to develop into the lymphocyte lineage but can give rise to all innate lymphoid cell lineages.

Autophagy and autophagy-related proteins in the immune system   pp1014 - 1024
Shusaku T Shibutani, Tatsuya Saitoh, Heike Nowag, Christian Münz and Tamotsu Yoshimori
doi:10.1038/ni.3273
Autophagy is an essential intracellular degradation process. Yoshimori and colleagues review the broad role of autophagy in immunological function.

Sequence-specific activation of the DNA sensor cGAS by Y-form DNA structures as found in primary HIV-1 cDNA   pp1025 - 1033
Anna-Maria Herzner, Cristina Amparo Hagmann, Marion Goldeck, Steven Wolter, Kirsten Kübler et al.
doi:10.1038/ni.3267
Truncated reverse transcription of HIV RNA produces a single-stranded DNA intermediate with a unique Y-DNA stem-loop structure flanked by unpaired guanines. Schlee and colleagues show this Y-DNA activates cGAS to elicit the production of type I interferon.

The transcription factor ATF7 mediates lipopolysaccharide-induced epigenetic changes in macrophages involved in innate immunological memory   pp1034 - 1043
Keisuke Yoshida, Toshio Maekawa, Yujuan Zhu, Claire Renard-Guillet, Bruno Chatton et al.
doi:10.1038/ni.3257
The role of the stress-induced transcription factor ATF7 in immunity is largely unknown. Ishii and colleagues show that ATF7 represses select innate immunity-related genes, but activity is downregulated during the induction of macrophage memory.

TCF-1 upregulation identifies early innate lymphoid progenitors in the bone marrow   pp1044 - 1050
Qi Yang, Fengyin Li, Christelle Harly, Shaojun Xing, Longyun Ye et al.
doi:10.1038/ni.3248
The cellular and molecular events that drive early innate lymphoid cell (ILC) development remain poorly understood. Bhandoola and colleagues used a reporter mouse to identify a new subset of early ILC progenitors (EILPs) that express high amounts of TCF-1.

Innate immunological function of TH2 cells in vivo   pp1051 - 1059
Liying Guo, Yuefeng Huang, Xi Chen, Jane Hu-Li, Joseph F Urban Jr et al.
doi:10.1038/ni.3244
T cells are normally dependent on TCR stimulation to be activated. Guo and colleagues now show that memory type 2 helper T cells can respond to interleukin 33 elicited by helminth infection in an TCR-independent way to induce eosinophilic inflammation.

CDKN1A regulates Langerhans cell survival and promotes Treg cell generation upon exposure to ionizing irradiation   pp1060 - 1068
Jeremy G Price, Juliana Idoyaga, Hélène Salmon, Brandon Hogstad, Carolina L Bigarella et al.
doi:10.1038/ni.3270
Treatment with ionizing radiation can lead to the accumulation of tumor-infiltrating Treg cells. Merad and colleagues show that Langherans cells resist ionizing radiation via expression of p21 and potentiate the generation and accumulation of Treg cells.

TCR affinity for thymoproteasome-dependent positively selecting peptides conditions antigen responsiveness in CD8+ T cells   pp1069 - 1076
Kensuke Takada, Francois Van Laethem, Yan Xing, Kazuyuki Akane, Haruhiko Suzuki et al.
doi:10.1038/ni.3237
In the thymus, low-affinity T cell antigen receptor (TCR) engagement facilitates positive selection of the T cell repertoire. Takahama and colleagues now show TCR responsiveness of mature CD8+ T cells is fine-tuned by their affinity for positively selecting peptides in the thymus.

The DNA-binding inhibitor Id3 regulates IL-9 production in CD4+ T cells   pp1077 - 1084
Hiroko Nakatsukasa, Dunfang Zhang, Takashi Maruyama, Hua Chen, Kairong Cui et al.
doi:10.1038/ni.3252
The molecular mechanisms that lead to TH9 differentiation remain unclear. Chen and colleagues show that TGF-β- and IL-4-induced downregulation of the transcriptional repressor Id3 is required for TH9 differentiation.

A discrete chromatin loop in the mouse Tcra-Tcrd locus shapes the TCRδ and TCRα repertoires   pp1085 - 1093
Liang Chen, Zachary Carico, Han-Yu Shih and Michael S Krangel
doi:10.1038/ni.3232
Tcra and Tcrd segments are embedded within a single locus but undergo distinct temporal rearrangements. Krangel and colleagues show that chromatin looping mediated by CTCF regulates the availability of variable gene segments to the RAG recombinase.

Histone reader BRWD1 targets and restricts recombination to the Igk locus   pp1094 - 1103
Malay Mandal, Keith M Hamel, Mark Maienschein-Cline, Azusa Tanaka, Grace Teng et al.
doi:10.1038/ni.3249
V(D)J recombination is developmentally regulated and occurs at restricted sites within the genome. Clark and colleagues show that the histone reader BRWD1 is required for precise positioning of nucleosomes and targeting of RAG recombinase proteins within the Igk locus.
