Journal ArticleDOI
Induction of Intestinal Th17 Cells by Segmented Filamentous Bacteria
Ivaylo I. Ivanov,Koji Atarashi,Nicolas Manel,Eoin L. Brodie,Tatsuichiro Shima,Ulas Karaoz,Dongguang Wei,Katherine C. Goldfarb,Clark A. Santee,Susan V. Lynch,Takeshi Tanoue,Akemi Imaoka,Kikuji Itoh,Kiyoshi Takeda,Yoshinori Umesaki,Kenya Honda,Dan R. Littman +16 more
TL;DR: The authors showed that colonisation of mice with a segmented filamentous bacterium (SFB) is sufficient to induce the appearance of CD4+ T helper cells that produce IL-17 and IL-22 (Th17 cells) in the lamina propria.
Journal ArticleDOI
Induction of Colonic Regulatory T Cells by Indigenous Clostridium Species
Koji Atarashi,Takeshi Tanoue,Tatsuichiro Shima,Akemi Imaoka,Tomomi Kuwahara,Yoshika Momose,Genhong Cheng,Sho Yamasaki,Takashi Saito,Yusuke Ohba,Tadatsugu Taniguchi,Kiyoshi Takeda,Shohei Hori,Ivaylo I. Ivanov,Yoshinori Umesaki,Kikuji Itoh,Kenya Honda,Kenya Honda +17 more
TL;DR: Oral inoculation of Clostridium during the early life of conventionally reared mice resulted in resistance to colitis and systemic immunoglobulin E responses in adult mice, suggesting a new therapeutic approach to autoimmunity and allergy.
Journal ArticleDOI
Gut-residing segmented filamentous bacteria drive autoimmune arthritis via T helper 17 cells
Hsin Jung Wu,Ivaylo I. Ivanov,Jaime Darce,Jaime Darce,Kimie Hattori,Kimie Hattori,Tatsuichiro Shima,Yoshinori Umesaki,Dan R. Littman,Christophe Benoist,Christophe Benoist,Christophe Benoist,Diane Mathis,Diane Mathis,Diane Mathis +14 more
TL;DR: It is reported that autoimmune arthritis was strongly attenuated in the K/BxN mouse model under germ-free (GF) conditions, accompanied by reductions in serum autoantibody titers, splenic autoantIBody-secreting cells, germinal centers, and the splenic T helper 17 (Th17) cell population.
Journal ArticleDOI
Proinflammatory T-cell responses to gut microbiota promote experimental autoimmune encephalomyelitis
TL;DR: It is revealed that the intestinal microbiota profoundly impacts the balance between pro- and antiinflammatory immune responses during EAE and suggest that modulation of gut bacteria may provide therapeutic targets for extraintestinal inflammatory diseases such as MS.
Journal ArticleDOI
ATP drives lamina propria T H 17 cell differentiation
Koji Atarashi,Junichi Nishimura,Tatsuichiro Shima,Yoshinori Umesaki,Masahiro Yamamoto,Masaharu Onoue,Hideo Yagita,Naoto Ishii,Richard J. Evans,Kenya Honda,Kiyoshi Takeda +10 more
TL;DR: It is shown that adenosine 5′-triphosphate (ATP) that can be derived from commensal bacteria activates a unique subset of lamina propria cells, CD70highCD11clow cells, leading to the differentiation of TH17 cells, and the critical role of ATP is underscored.
