 | | Focus on Tissue-resident leukocytes |  | Focus issue: October 2013 Volume 14 No 10 | | Immune cells are found in diverse nonlymphoid tissues where they patrol against infection and injury and help to maintain homeostasis. This month's Focus features five specially commissioned Reviews that discuss interactions and functions of tissue-resident leukocytes. |

Focus on Tissue-resident leukocytes The skin-resident and migratory immune system in steady state and memory: innate lymphocytes, dendritic cells and T cells pp978 - 985 William R Heath and Francis R Carbone doi:10.1038/ni.2680 The skin is a highly complex organ and the main body barrier against pathogens and other environmental factors. Heath and Carbone outline many of the innate and adaptive immune cell types associated with the skin.

Focus on Tissue-resident leukocytes Tissue-resident macrophages pp986 - 995 Luke C Davies, Stephen J Jenkins, Judith E Allen and Philip R Taylor doi:10.1038/ni.2705 Macrophages populate tissues under homeostatic conditions. Taylor and colleagues discuss the heterogeneity of tissue macrophage populations, and how they contribute to tissue function and immune surveillance.

Focus on Tissue-resident leukocytes Immune surveillance by the liver pp996 - 1006 Craig N Jenne and Paul Kubes doi:10.1038/ni.2691 The liver is important in mediating immunity to blood-borne infections. Jenne and Kubes review the liver as an immune organ and discuss the roles of liver-resident cells and their interactions with circulating immune cells.

Focus on Tissue-resident leukocytes Regulatory T cells in nonlymphoid tissues pp1007 - 1013 Dalia Burzyn, Christophe Benoist and Diane Mathis doi:10.1038/ni.2683 Regulatory T (Treg) cells modulate immune cell responses. Mathis and colleagues review the specialized roles played by tissue-specific Treg cells and reveal new functions that can be attributed to distinct Treg cell subsets.

Focus on Tissue-resident leukocytes Innate and adaptive immune cells in the tumor microenvironment pp1014 - 1022 Thomas F Gajewski, Hans Schreiber and Yang-Xin Fu doi:10.1038/ni.2703 Tumors can evade immune system-mediated destruction despite expressing antigenic neoepitopes. Gajewski, Schreiber and Fu discuss how the tumor microenvironment harnesses innate and adaptive immune cell regulatory processes to promote tumor survival.

GATA-3 regulates the self-renewal of long-term hematopoietic stem cells pp1037 - 1044 Catherine Frelin, Robert Herrington, Salima Janmohamed, Mary Barbara, Gary Tran et al. doi:10.1038/ni.2692 Although GATA-3 is expressed in hematopoietic stem cells, its function there remains unclear. Iscove and colleagues show that GATA-3 inhibits the self-renewal potential of long-term hematopoietic stem cells downstream of p38 signaling.

Fatty acid-induced mitochondrial uncoupling elicits inflammasome-independent IL-1α and sterile vascular inflammation in atherosclerosis pp1045 - 1053 Stefan Freigang, Franziska Ampenberger, Adrienne Weiss, Thirumala-Devi Kanneganti, Yoichiro Iwakura et al. doi:10.1038/ni.2704 Chronic inflammation is a fundamental aspect of metabolic disorders such as atherosclerosis. Freigang and colleagues report that fatty acids are potent inducers of IL-1α, which drives vascular inflammation.

IL-27 acts on DCs to suppress the T cell response and autoimmunity by inducing expression of the immunoregulatory molecule CD39 pp1054 - 1063 Ivan D Mascanfroni, Ada Yeste, Silvio M Vieira, Evan J Burns, Bonny Patel et al. doi:10.1038/ni.2695 The immunoregulatory effect of IL-27 is thought to act mainly on T cells. Quintana and colleagues show that IL-27 also converts conventional DCs into immunosuppressive cells.

Rapid effector function of memory CD8+ T cells requires an immediate-early glycolytic switch pp1064 - 1072 Patrick M Gubser, Glenn R Bantug, Leyla Razik, Marco Fischer, Sarah Dimeloe et al. doi:10.1038/ni.2687 Effector memory CD8+ T cells are capable of rapid IFN-γ production. Hess and colleagues show that antigenic reactivation triggers enhanced glycolytic flux, which is required for early IFN-γ recall responses.

Selective regulation of lymphopoiesis and leukemogenesis by individual zinc fingers of Ikaros pp1073 - 1083 Hilde Schjerven, Jami McLaughlin, Teresita L Arenzana, Seth Frietze, Donghui Cheng et al. doi:10.1038/ni.2707 The transcription factor Ikaros, which is essential for lymphocyte development, contains multiple zinc fingers. Smale and colleagues show that mice lacking different zinc fingers develop distinct lymphocyte-developmental defects and tumor susceptibility.

MEF2B mutations lead to deregulated expression of the oncogene BCL6 in diffuse large B cell lymphoma pp1084 - 1092 Carol Y Ying, David Dominguez-Sola, Melissa Fabi, Ivo C Lorenz, Shafinaz Hussein et al. doi:10.1038/ni.2688 Diffuse large B cell lymphomas can arise from dysregulation of BCL6 expression. Dalla-Favera and colleagues show that the transcription factor MEF2B regulates BCL6 and is commonly associated with the generation of such lymphomas.

Epigenetic and transcriptional signatures of stable versus plastic differentiation of proinflammatory γδ T cell subsets pp1093 - 1100 Nina Schmolka, Karine Serre, Ana R Grosso, Margarida Rei, Daniel J Pennington et al. doi:10.1038/ni.2702 Silva-Santos and colleagues use genome-wide characterization of the methylation patterns of histone H3 and analysis of transcription factor expression to identify the regulatory framework of peripheral interferon-γ-producing or interleukin 17-producing γδ T cell subsets.
