CD8-positive, alpha-beta cytokine secreting effector T cell Tc17 cell A CD8-positive, alpha-beta T cell that has the phenotype CXCR3-negative, CCR6-positive, CCR5-high, CD45RA-negative, and capable of producing IL-17 and some IFNg. Tc17 T cell Tc17 T lymphocyte Tc17 T-cell Tc17 T-lymphocyte This cell type is compatible with the HIPC Lyoplate markers for 'Tc17 CD8+ T cell', but its logical definition includes additional known characteristics of Tc17 T cells. Found in the CD27-positive, CD28-positive or CD27-negative, CD28-positive fractions with the phenotype CCR4-negative and CCR7-negative (this sentence not part of definition). cell Tc17 CD8+ T cell
