Circulating $ CXCR5^{−} $PD-$ 1^{hi} $ peripheral T helper cells are associated with progression to type 1 diabetes
Aims/hypothesis Type 1 diabetes is preceded by a period of asymptomatic autoimmunity characterised by positivity for islet autoantibodies. Therefore, T helper cell responses that induce B cell activation are likely to play a critical role in the disease process. Here, we aimed to evaluate the role o...

Therefore, T helper cell responses that induce B cell activation are likely to play a critical role in the disease process. Here, we aimed to evaluate the role of a recently described subset, C-X-C motif chemokine receptor type 5-negative, programmed cell death protein 1-positive ($ CXCR5^{−} $PD-$ 1^{hi} $) peripheral T helper (Tph) cells, in human type 1 diabetes. Methods The phenotype of blood $ CXCR5^{−} $PD-$ 1^{hi} $ $ CD4^{+} $ T cells was analysed by multicolour flow cytometry. The frequencies of circulating $ CXCR5^{−} $PD-$ 1^{hi} $ T cells were analysed in a cohort of 44 children with newly diagnosed type 1 diabetes, 40 autoantibody-positive ($ AAb^{+} $) at-risk children and 84 autoantibody-negative healthy control children, and the findings were replicated in a separate cohort of 15 children with newly diagnosed type 1 diabetes and 15 healthy control children. Results Circulating $ CXCR5^{−} $PD-$ 1^{hi} $ Tph cells share several features associated with B cell helper function with circulating $ CXCR5^{+} $PD-$ 1^{hi} $ follicular T helper (Tfh) cells. Moreover, the frequency of circulating Tph cells was increased in children with newly diagnosed type 1 diabetes, especially in those who are positive for multiple autoantibodies. Importantly, circulating Tph cells were also increased in autoantibody-positive at-risk children who later progressed to type 1 diabetes. Conclusions/interpretation Our results demonstrate that circulating $ CXCR5^{−} $PD-$ 1^{hi} $ Tph cells are associated with progression to clinical type 1 diabetes. Consequently, Tph cells could have potential both as a biomarker of disease progression and as a target for immunotherapy in type 1 diabetes. | ||

Therefore, T helper cell responses that induce B cell activation are likely to play a critical role in the disease process. Here, we aimed to evaluate the role of a recently described subset, C-X-C motif chemokine receptor type 5-negative, programmed cell death protein 1-positive ($ CXCR5^{−} $PD-$ 1^{hi} $) peripheral T helper (Tph) cells, in human type 1 diabetes. Methods The phenotype of blood $ CXCR5^{−} $PD-$ 1^{hi} $ $ CD4^{+} $ T cells was analysed by multicolour flow cytometry. The frequencies of circulating $ CXCR5^{−} $PD-$ 1^{hi} $ T cells were analysed in a cohort of 44 children with newly diagnosed type 1 diabetes, 40 autoantibody-positive ($ AAb^{+} $) at-risk children and 84 autoantibody-negative healthy control children, and the findings were replicated in a separate cohort of 15 children with newly diagnosed type 1 diabetes and 15 healthy control children. Results Circulating $ CXCR5^{−} $PD-$ 1^{hi} $ Tph cells share several features associated with B cell helper function with circulating $ CXCR5^{+} $PD-$ 1^{hi} $ follicular T helper (Tfh) cells. Moreover, the frequency of circulating Tph cells was increased in children with newly diagnosed type 1 diabetes, especially in those who are positive for multiple autoantibodies. Importantly, circulating Tph cells were also increased in autoantibody-positive at-risk children who later progressed to type 1 diabetes. Conclusions/interpretation Our results demonstrate that circulating $ CXCR5^{−} $PD-$ 1^{hi} $ Tph cells are associated with progression to clinical type 1 diabetes. Consequently, Tph cells could have potential both as a biomarker of disease progression and as a target for immunotherapy in type 1 diabetes.

Therefore, T helper cell responses that induce B cell activation are likely to play a critical role in the disease process. Here, we aimed to evaluate the role of a recently described subset, C-X-C motif chemokine receptor type 5-negative, programmed cell death protein 1-positive ($ CXCR5^{−} $PD-$ 1^{hi} $) peripheral T helper (Tph) cells, in human type 1 diabetes. Methods The phenotype of blood $ CXCR5^{−} $PD-$ 1^{hi} $ $ CD4^{+} $ T cells was analysed by multicolour flow cytometry. The frequencies of circulating $ CXCR5^{−} $PD-$ 1^{hi} $ T cells were analysed in a cohort of 44 children with newly diagnosed type 1 diabetes, 40 autoantibody-positive ($ AAb^{+} $) at-risk children and 84 autoantibody-negative healthy control children, and the findings were replicated in a separate cohort of 15 children with newly diagnosed type 1 diabetes and 15 healthy control children. Results Circulating $ CXCR5^{−} $PD-$ 1^{hi} $ Tph cells share several features associated with B cell helper function with circulating $ CXCR5^{+} $PD-$ 1^{hi} $ follicular T helper (Tfh) cells. Moreover, the frequency of circulating Tph cells was increased in children with newly diagnosed type 1 diabetes, especially in those who are positive for multiple autoantibodies. Importantly, circulating Tph cells were also increased in autoantibody-positive at-risk children who later progressed to type 1 diabetes. Conclusions/interpretation Our results demonstrate that circulating $ CXCR5^{−} $PD-$ 1^{hi} $ Tph cells are associated with progression to clinical type 1 diabetes. Consequently, Tph cells could have potential both as a biomarker of disease progression and as a target for immunotherapy in type 1 diabetes.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Autoimmunity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">B cells</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Follicular T helper cell</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Human</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Immunophenotyping</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Peripheral T helper cell</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">T cells</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Type 1 diabetes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ihantola, Emmi-Leena</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Viisanen, Tyyne</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rao, Deepak A.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Näntö-Salonen, Kirsti</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Knip, Mikael</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Veijola, Riitta</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Toppari, Jorma</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ilonen, Jorma</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kinnunen, Tuure</subfield><subfield code="0">(orcid)0000-0003-1595-5371</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Diabetologia</subfield><subfield code="d">Berlin : Springer, 1965</subfield><subfield code="g">62(2019), 9 vom: 03.

abstract |
Aims/hypothesis Type 1 diabetes is preceded by a period of asymptomatic autoimmunity characterised by positivity for islet autoantibodies. Therefore, T helper cell responses that induce B cell activation are likely to play a critical role in the disease process. Here, we aimed to evaluate the role of a recently described subset, C-X-C motif chemokine receptor type 5-negative, programmed cell death protein 1-positive ($ CXCR5^{−} $PD-$ 1^{hi} $) peripheral T helper (Tph) cells, in human type 1 diabetes. Methods The phenotype of blood $ CXCR5^{−} $PD-$ 1^{hi} $ $ CD4^{+} $ T cells was analysed by multicolour flow cytometry. The frequencies of circulating $ CXCR5^{−} $PD-$ 1^{hi} $ T cells were analysed in a cohort of 44 children with newly diagnosed type 1 diabetes, 40 autoantibody-positive ($ AAb^{+} $) at-risk children and 84 autoantibody-negative healthy control children, and the findings were replicated in a separate cohort of 15 children with newly diagnosed type 1 diabetes and 15 healthy control children. Results Circulating $ CXCR5^{−} $PD-$ 1^{hi} $ Tph cells share several features associated with B cell helper function with circulating $ CXCR5^{+} $PD-$ 1^{hi} $ follicular T helper (Tfh) cells. Moreover, the frequency of circulating Tph cells was increased in children with newly diagnosed type 1 diabetes, especially in those who are positive for multiple autoantibodies. Importantly, circulating Tph cells were also increased in autoantibody-positive at-risk children who later progressed to type 1 diabetes. Conclusions/interpretation Our results demonstrate that circulating $ CXCR5^{−} $PD-$ 1^{hi} $ Tph cells are associated with progression to clinical type 1 diabetes. Consequently, Tph cells could have potential both as a biomarker of disease progression and as a target for immunotherapy in type 1 diabetes. © The Author(s) 2019 |

Consequently, Tph cells could have potential both as a biomarker of disease progression and as a target for immunotherapy in type 1 diabetes.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Autoimmunity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">B cells</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Follicular T helper cell</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Human</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Immunophenotyping</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Peripheral T helper cell</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">T cells</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Type 1 diabetes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ihantola, Emmi-Leena</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Viisanen, Tyyne</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rao, Deepak A.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Näntö-Salonen, Kirsti</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Knip, Mikael</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Veijola, Riitta</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Toppari, Jorma</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ilonen, Jorma</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kinnunen, Tuure</subfield><subfield code="0">(orcid)0000-0003-1595-5371</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Diabetologia</subfield><subfield code="d">Berlin : Springer, 1965</subfield><subfield code="g">62(2019), 9 vom: 03.
