Although, cytokine production by non-T cells is an important factor in helper T cell differentiation, a characteristic feature of both Th1 and Th2 lineages is their ability to secrete cytokines that promote their respective differentiation. However, cytokines produced by T cells that help to sustain Th17 cells have not yet been identified. Here we show that IL-21 is a product of Th17 cells,"; prov:wasQuotedFrom pubmed:17884812 . sub:_4 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:17884812; prov:wasDerivedFrom beldoc:, sub:_3 . } sub:pubinfo { this: dct:created "2014-07-03T14:33:12.523+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
