    IL25 elicits a multipotent progenitor cell population that promotes T(H)2 cytokine responses (2010)
    Nature Publishing Group (NPG)

    Publication Date: 2010-03-05
    Description: CD4(+) T helper 2 (T(H)2) cells secrete interleukin (IL)4, IL5 and IL13, and are required for immunity to gastrointestinal helminth infections. However, T(H)2 cells also promote chronic inflammation associated with asthma and allergic disorders. The non-haematopoietic-cell-derived cytokines thymic stromal lymphopoietin, IL33 and IL25 (also known as IL17E) have been implicated in inducing T(H)2 cell-dependent inflammation at mucosal sites, but how these cytokines influence innate immune responses remains poorly defined. Here we show that IL25, a member of the IL17 cytokine family, promotes the accumulation of a lineage-negative (Lin(-)) multipotent progenitor (MPP) cell population in the gut-associated lymphoid tissue that promotes T(H)2 cytokine responses. The IL25-elicited cell population, termed MPP(type2) cells, was defined by the expression of Sca-1 (also known as Ly6a) and intermediate expression of c-Kit (c-Kit(int)), and exhibited multipotent capacity, giving rise to cells of monocyte/macrophage and granulocyte lineages both in vitro and in vivo. Progeny of MPP(type2) cells were competent antigen presenting cells, and adoptive transfer of MPP(type2) cells could promote T(H)2 cytokine responses and confer protective immunity to helminth infection in normally susceptible Il25(-/-) mice. The ability of IL25 to induce the emergence of an MPP(type2) cell population identifies a link between the IL17 cytokine family and extramedullary haematopoiesis, and suggests a previously unrecognized innate immune pathway that promotes T(H)2 cytokine responses at mucosal sites.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2861732/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2861732/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saenz, Steven A -- Siracusa, Mark C -- Perrigoue, Jacqueline G -- Spencer, Sean P -- Urban, Joseph F Jr -- Tocker, Joel E -- Budelsky, Alison L -- Kleinschek, Melanie A -- Kastelein, Robert A -- Kambayashi, Taku -- Bhandoola, Avinash -- Artis, David -- AI074878/AI/NIAID NIH HHS/ -- AI083480/AI/NIAID NIH HHS/ -- AI61570/AI/NIAID NIH HHS/ -- F31GM082187/GM/NIGMS NIH HHS/ -- P30 DK50306/DK/NIDDK NIH HHS/ -- R01 AI061570/AI/NIAID NIH HHS/ -- R01 AI061570-06/AI/NIAID NIH HHS/ -- R01 AI074878/AI/NIAID NIH HHS/ -- R01 AI074878-03/AI/NIAID NIH HHS/ -- R01 AI095466/AI/NIAID NIH HHS/ -- R01 AI102942/AI/NIAID NIH HHS/ -- R21 AI083480/AI/NIAID NIH HHS/ -- R21 AI083480-01/AI/NIAID NIH HHS/ -- T32AI007532-08/AI/NIAID NIH HHS/ -- England -- Nature. 2010 Apr 29;464(7293):1362-6. doi: 10.1038/nature08901.

    TSLP promotes interleukin-3-independent basophil haematopoiesis and type 2 inflammation (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-08-16
    Description: CD4(+) T-helper type 2 (T(H)2) cells, characterized by their expression of interleukin (IL)-4, IL-5, IL-9 and IL-13, are required for immunity to helminth parasites and promote the pathological inflammation associated with asthma and allergic diseases. Polymorphisms in the gene encoding the cytokine thymic stromal lymphopoietin (TSLP) are associated with the development of multiple allergic disorders in humans, indicating that TSLP is a critical regulator of T(H)2 cytokine-associated inflammatory diseases. In support of genetic analyses, exaggerated TSLP production is associated with asthma, atopic dermatitis and food allergies in patients, and studies in murine systems demonstrated that TSLP promotes T(H)2 cytokine-mediated immunity and inflammation. However, the mechanisms through which TSLP induces T(H)2 cytokine responses remain poorly defined. Here we demonstrate that TSLP promotes systemic basophilia, that disruption of TSLP-TSLPR interactions results in defective basophil responses, and that TSLPR-sufficient basophils can restore T(H)2-cell-dependent immunity in vivo. TSLP acted directly on bone-marrow-resident progenitors to promote basophil responses selectively. Critically, TSLP could elicit basophil responses in both IL-3-IL-3R-sufficient and -deficient environments, and genome-wide transcriptional profiling and functional analyses identified heterogeneity between TSLP-elicited versus IL-3-elicited basophils. Furthermore, activated human basophils expressed TSLPR, and basophils isolated from eosinophilic oesophagitis patients were distinct from classical basophils. Collectively, these studies identify previously unrecognized heterogeneity within the basophil cell lineage and indicate that expression of TSLP may influence susceptibility to multiple allergic diseases by regulating basophil haematopoiesis and eliciting a population of functionally distinct basophils that promote T(H)2 cytokine-mediated inflammation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3263308/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3263308/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Siracusa, Mark C -- Saenz, Steven A -- Hill, David A -- Kim, Brian S -- Headley, Mark B -- Doering, Travis A -- Wherry, E John -- Jessup, Heidi K -- Siegel, Lori A -- Kambayashi, Taku -- Dudek, Emily C -- Kubo, Masato -- Cianferoni, Antonella -- Spergel, Jonathan M -- Ziegler, Steven F -- Comeau, Michael R -- Artis, David -- AI083480/AI/NIAID NIH HHS/ -- AI61570/AI/NIAID NIH HHS/ -- AI74878/AI/NIAID NIH HHS/ -- AI87990/AI/NIAID NIH HHS/ -- F31 GM082187/GM/NIGMS NIH HHS/ -- F32 AI085828/AI/NIAID NIH HHS/ -- R01 AI061570/AI/NIAID NIH HHS/ -- R01 AI061570-09/AI/NIAID NIH HHS/ -- R01 AI074878/AI/NIAID NIH HHS/ -- R01 AI074878-05/AI/NIAID NIH HHS/ -- R01 AI095466/AI/NIAID NIH HHS/ -- R01 AI095466-02/AI/NIAID NIH HHS/ -- R01 HL107589/HL/NHLBI NIH HHS/ -- R21 AI083480/AI/NIAID NIH HHS/ -- R21 AI083480-02/AI/NIAID NIH HHS/ -- T32 AI060516/AI/NIAID NIH HHS/ -- U01 AI095608/AI/NIAID NIH HHS/ -- U01 AI095608-02/AI/NIAID NIH HHS/ -- England -- Nature. 2011 Aug 14;477(7363):229-33. doi: 10.1038/nature10329.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Immunology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21841801" target="_blank"〉PubMed〈/a〉

    Coinfection. Virus-helminth coinfection reveals a microbiota-independent mechanism of immunomodulation (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-08-02
    Description: The mammalian intestine is colonized by beneficial commensal bacteria and is a site of infection by pathogens, including helminth parasites. Helminths induce potent immunomodulatory effects, but whether these effects are mediated by direct regulation of host immunity or indirectly through eliciting changes in the microbiota is unknown. We tested this in the context of virus-helminth coinfection. Helminth coinfection resulted in impaired antiviral immunity and was associated with changes in the microbiota and STAT6-dependent helminth-induced alternative activation of macrophages. Notably, helminth-induced impairment of antiviral immunity was evident in germ-free mice, but neutralization of Ym1, a chitinase-like molecule that is associated with alternatively activated macrophages, could partially restore antiviral immunity. These data indicate that helminth-induced immunomodulation occurs independently of changes in the microbiota but is dependent on Ym1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4548887/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4548887/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Osborne, Lisa C -- Monticelli, Laurel A -- Nice, Timothy J -- Sutherland, Tara E -- Siracusa, Mark C -- Hepworth, Matthew R -- Tomov, Vesselin T -- Kobuley, Dmytro -- Tran, Sara V -- Bittinger, Kyle -- Bailey, Aubrey G -- Laughlin, Alice L -- Boucher, Jean-Luc -- Wherry, E John -- Bushman, Frederic D -- Allen, Judith E -- Virgin, Herbert W -- Artis, David -- 095831/Wellcome Trust/United Kingdom -- 2-P30 CA016520/CA/NCI NIH HHS/ -- 5T32A100716334/PHS HHS/ -- AI061570/AI/NIAID NIH HHS/ -- AI074878/AI/NIAID NIH HHS/ -- AI082630/AI/NIAID NIH HHS/ -- AI083022/AI/NIAID NIH HHS/ -- AI087990/AI/NIAID NIH HHS/ -- AI095466/AI/NIAID NIH HHS/ -- AI095608/AI/NIAID NIH HHS/ -- AI097333/AI/NIAID NIH HHS/ -- AI102942/AI/NIAID NIH HHS/ -- AI106697/AI/NIAID NIH HHS/ -- F32 AI085828/AI/NIAID NIH HHS/ -- F32-AI085828/AI/NIAID NIH HHS/ -- HHSN272201300006C/PHS HHS/ -- K08 DK097301/DK/NIDDK NIH HHS/ -- K08-DK097301/DK/NIDDK NIH HHS/ -- MR/J001929/1/Medical Research Council/United Kingdom -- P01 AI106697/AI/NIAID NIH HHS/ -- P30-AI045008/AI/NIAID NIH HHS/ -- P30-DK050306/DK/NIDDK NIH HHS/ -- R01 AI 084887/AI/NIAID NIH HHS/ -- R01 AI061570/AI/NIAID NIH HHS/ -- R01 AI074878/AI/NIAID NIH HHS/ -- R01 AI095466/AI/NIAID NIH HHS/ -- R01 AI097333/AI/NIAID NIH HHS/ -- R01 AI102942/AI/NIAID NIH HHS/ -- R21 AI087990/AI/NIAID NIH HHS/ -- T32-AI007532/AI/NIAID NIH HHS/ -- U01 AI095608/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Aug 1;345(6196):578-82. doi: 10.1126/science.1256942.
