Nature Immunology FOCUS ON TISSUE-RESIDENT LEUKOCYTES
Tissue-resident immune cells communicate with resident stromal cells to patrol and monitor against infection and tissue damage. Nature Immunology presents five specially commissioned Reviews that discuss interactions and functions of tissue-resident leukocytes within nonlymphoid tissues during healthy steady state, upon infection and within tumor environments. | |

Job-search basics: a scientific approach to interviewing pp1199 - 1201 Derek Haseltine and James Gould doi:10.1038/ni.2748 Successful interviewing can be best attributed to a combination of careful research and preparation, along with the ability to connect with employers on a personal level and demonstrate value.

A rheostat for immune responses: the unique properties of PD-1 and their advantages for clinical application pp1212 - 1218 Taku Okazaki, Shunsuke Chikuma, Yoshiko Iwai, Sidonia Fagarasan and Tasuku Honjo doi:10.1038/ni.2762

Pathogen signatures activate a ubiquitination pathway that modulates the function of the metabolic checkpoint kinase mTOR pp1219 - 1228 Stanimir S Ivanov and Craig R Roy doi:10.1038/ni.2740 Discriminating between harmless and pathogenic bacteria is a key challenge faced by the immune system. Ivanov and Roy demonstrate that virulent bacteria disrupt mTOR signaling, which then skews responses towards inflammatory cytokine production.

Specification of type 2 innate lymphocytes by the transcriptional determinant Gfi1 pp1229 - 1236 Chauncey J Spooner, Justin Lesch, Donghong Yan, Aly A Khan, Alex Abbas et al. doi:10.1038/ni.2743 Type 2 innate lymphoid cells (ILC2 cells) provide early immune responses to helminthes and contribute to allergic inflammation. Singh and colleagues show that the transcription factor Gfi1 controls the development, activation and specification of ILC2 cells.

ELF4 is critical for induction of type I interferon and the host antiviral response pp1237 - 1246 Fuping You, Penghua Wang, Long Yang, Guang Yang, Yang O Zhao et al. doi:10.1038/ni.2756 Induction of type I interferon is a central event of antiviral immune responses. Fikrig and colleagues show that the transcription factor ELF4 is recruited by STING and translocates to the nucleus to control transcription of type I interferon genes.

Phosphorylation of the adaptor ASC acts as a molecular switch that controls the formation of speck-like aggregates and inflammasome activity pp1247 - 1255 Hideki Hara, Kohsuke Tsuchiya, Ikuo Kawamura, Rendong Fang, Eduardo Hernandez-Cuellar et al. doi:10.1038/ni.2749 The adaptor ASC is required for caspase-1 activation via the NLRP3 and AIM2 inflammasomes. Mitsuyama and colleagues show that signaling dependent on the kinases Syk and Jnk controls ASC speck formation through ASC phosphorylation.

The HIV-1 envelope protein gp120 impairs B cell proliferation by inducing TGF-β1 production and FcRL4 expression pp1256 - 1265 Katija Jelicic, Raffaello Cimbro, Fatima Nawaz, Da Wei Huang, Xin Zheng et al. doi:10.1038/ni.2746 Antibody responses are impaired during HIV-1 infection. Cicala and colleagues show that the HIV-1 glycoprotein gp120 directly impairs B cell function by promoting expression of TGF-β and the inhibitory receptor FcRL4.

The kinase mTOR modulates the antibody response to provide cross-protective immunity to lethal infection with influenza virus pp1266 - 1276 Rachael Keating, Tomer Hertz, Marie Wehenkel, Tarsha L Harris, Benjamin A Edwards et al. doi:10.1038/ni.2741 Influenza viruses are highly variable, which complicates vaccine strategies to protect against emerging viruses. McGargill and colleagues show that blocking the mTORC1 complex skews antibody responses to more conserved epitopes, thereby producing heterosubtypic protection.

T cell development requires constraint of the myeloid regulator C/EBP-α by the Notch target and transcriptional repressor Hes1 pp1277 - 1284 Maria Elena De Obaldia, J Jeremiah Bell, Xinxin Wang, Christelle Harly, Yumi Yashiro-Ohtani et al. doi:10.1038/ni.2760 Hematopoietic deficiency in the Notch target Hes1 results in severe defects in the T cell lineage. Bhandoola and colleagues show that Hes1 constrains myeloid gene-expression programs in T cell progenitors.

Transcriptional downregulation of S1pr1 is required for the establishment of resident memory CD8+ T cells pp1285 - 1293 Cara N Skon, June-Yong Lee, Kristin G Anderson, David Masopust, Kristin A Hogquist et al. doi:10.1038/ni.2745 Jameson and colleagues show that the establishment of resident memory CD8+ T cells in nonlymphoid tissues requires transcriptional downregulation of the trafficking molecule S1P1, mediated by induced loss of the transcription factor KLF2.

The developmental pathway for CD103+CD8+ tissue-resident memory T cells of skin pp1294 - 1301 Laura K Mackay, Azad Rahimpour, Joel Z Ma, Nicholas Collins, Angus T Stock et al. doi:10.1038/ni.2744 Long-lived tissue-resident memory T cells (TRM cells) confer fast, robust protection after pathogen rechallenge. Gebhardt and colleagues show that skin TRM cells arise from KLRG1- cells that differentiate in situ in response to IL-15 and TGF-β.

Nature Methods COLLECTION ON LIGHT-SHEET MICROSCOPY
The use of a planar sheet of light for illumination in light-sheet fluorescence microscopy allows researchers to image sample volumes faster than is possible with other current methods, while limiting light dosage. A collection of articles from Nature Methods, Nature Communications and Nature Reviews Molecular Cell Biology provides a brief overview of this exciting imaging technology and the biological research applications that it makes possible.
