A vision and a prescription for big data-enabled medicine   pp435 - 439
Damien Chaussabel and Bali Pulendran
doi:10.1038/ni.3151
Genetic, environmental and socioeconomic factors render humanity remarkably diverse. '-Omic' and sensor technologies permit the capture of this diversity with unprecedented precision. Leveraging these technologies in clinical decision making will help to bring about the long-heralded personalization of medicine.

Brainless immunity no more   pp440 - 441
Sachin P Gadani and Jonathan Kipnis
doi:10.1038/ni.3145
The mediobasal hypothalamus detects increased amounts of tumor necrosis factor during the early phases of inflammation and relays this information to cells of the adaptive immune system by mobilizing free fatty acids.

Cytoplasmic methylation fuels leukocyte invasion   pp441 - 443
Bernhard Wehrle-Haller
doi:10.1038/ni.3142
The methyltransferase Ezh2, an epigenetic regulator associated with tumor-cell metastasis, also methlyates the cytoplasmic integrin adaptor talin. This modification inhibits the binding of talin to F-actin, which enhances the migration and invasion of dendritic cells and neutrophils.

GBPs take AIM at Francisella   pp443 - 444
Katherine A Fitzgerald and Vijay A K Rathinam
doi:10.1038/ni.3144
Guanylate-binding proteins (GBPs) induced by type I interferon signaling cause lysis of Francisella bacteria that have reached the host-cell cytosol. The liberated bacterial DNA is then sensed by the cytosolic AIM2 inflammasome, which activates caspase-1 and leads to pyroptotic cell death.

TREML4 adds fuel to the TLR7 fire   pp445 - 446
Mihai G Netea and Frank L van de Veerdonk
doi:10.1038/ni.3149
The cell-surface receptor TREML4 amplifies cellular responses to single-stranded RNA by regulating recruitment of the adaptor MyD88 to the receptor TLR7. Mice lacking TREML4 show impaired antiviral immunity but also reduced severity of lupus-like disease.

IL-6 as a keystone cytokine in health and disease   pp448 - 457
Christopher A Hunter and Simon A Jones
doi:10.1038/ni.3153
IL-6 has context-dependent pro- and anti-inflammatory properties and is now regarded as a prominent target for clinical intervention. Hunter and Jones discuss the effect of IL-6 on innate and adaptive immunity, and consider how the immunobiology of IL-6 may inform clinical decisions.

The kinase Jnk2 promotes stress-induced mitophagy by targeting the small mitochondrial form of the tumor suppressor ARF for degradation   pp458 - 466
Qiao Zhang, Hong Kuang, Cong Chen, Jie Yan, Hanh Chi Do-Umehara et al.
doi:10.1038/ni.3130
Cells closely monitor mitochondrial status. Liu and colleagues show that the kinase Jnk2 regulates mitophagy by inhibiting smARF. Loss of Jnk2 results in defective mitophagy and enhanced ROS generation during hypoxia, which leads to enhanced inflammasome activation.

The transcription factor IRF1 and guanylate-binding proteins target activation of the AIM2 inflammasome by Francisella infection   pp467 - 475
Si Ming Man, Rajendra Karki, R K Subbarao Malireddi, Geoffrey Neale, Peter Vogel et al.
doi:10.1038/ni.3118
The mechanisms that control activation of the AIM2 inflammasome by cytosolic bacteria are unclear. Kanneganti and colleagues demonstrate that a pathway involving the transcription factor IRF1 is required for the activation of AIM2.

Guanylate-binding proteins promote activation of the AIM2 inflammasome during infection with Francisella novicida   pp476 - 484
Etienne Meunier, Pierre Wallet, Roland F Dreier, Stéphanie Costanzo, Leonie Anton et al.
doi:10.1038/ni.3119
How host cells induce the release of DNA from cytosolic bacteria is unclear. Broz and colleagues show that the guanylate-binding proteins GBP2 and GBP5 trigger bacteriolysis in infected host cells and thereby allow recognition by the sensor AIM2.

Senataxin suppresses the antiviral transcriptional response and controls viral biogenesis   pp485 - 494
Matthew S Miller, Alexander Rialdi, Jessica Sook Yuin Ho, Micah Tilove, Luis Martinez-Gil et al.
doi:10.1038/ni.3132
Mutations in the gene encoding the helicase senataxin have well established associations with the neurodegenerative disease ALS. Marazzi et al. show that senataxin can also attenuate virus-triggered responses by controlling RNA polymerase activity at genes encoding antiviral molecules.

The receptor TREML4 amplifies TLR7-mediated signaling during antiviral responses and autoimmunity   pp495 - 504
Zaida G Ramirez-Ortiz, Amit Prasad, Jason W Griffith, William F Pendergraft III, Glenn S Cowley et al.
doi:10.1038/ni.3143
Fine-tuning of TLR7 signaling modulates innate inflammatory responses. Means and colleagues identify the receptor TREML4 as an essential positive regulator of TLR7 signaling during antiviral responses and autoimmunity.

The methyltransferase Ezh2 controls cell adhesion and migration through direct methylation of the extranuclear regulatory protein talin   pp505 - 516
Merry Gunawan, Nandini Venkatesan, Jia Tong Loh, Jong Fu Wong, Heidi Berger et al.
doi:10.1038/ni.3125
Ezh2 is a protein methylase that epigenetically modifies chromatin. Su and colleagues identify a cytoplasmic role for Ezh2 whereby it controls the extravasation of innate leukocytes through methylation of talin and thereby influences inflammatory responses in vivo.

Let-7 microRNAs target the lineage-specific transcription factor PLZF to regulate terminal NKT cell differentiation and effector function   pp517 - 524
Leonid A Pobezinsky, Ruth Etzensperger, Susanna Jeurling, Amala Alag, Tejas Kadakia et al.
doi:10.1038/ni.3146
Singer and colleagues show that let-7 microRNAs target Zbtb16 mRNA, which encodes the transcription factor PLZF, to modulate PLZF expression during the terminal differentiation of NKT cells into effector subsets.

Rapid linkage of innate immunological signals to adaptive immunity by the brain-fat axis   pp525 - 533
Min Soo Kim, Jingqi Yan, Wenhe Wu, Guo Zhang, Yalin Zhang et al.
doi:10.1038/ni.3133
Peripheral innate immunological signals can amplify adaptive immune responses. Cai and colleagues show that hypothalamicexposure to the cytokine TNF triggers a neural response that amplifies peripheral lymphocyte activation in the spleen and adipose tissues.

Responsiveness of B cells is regulated by the hinge region of IgD   pp534 - 543
Rudolf Übelhart, Eva Hug, Martina P Bach, Thomas Wossning, Marcus Dühren-von Minden et al.
doi:10.1038/ni.3141
Mature naive B cells express membrane IgM and IgD B cell receptors. Jumaa and colleagues show that the hinge region of these regions confers differential responses to monovalent versus multivalent antigens and thereby influences B cell reactivity.
