These data are consistent with results from Yang et al. [21], who analyzed human DLBCL, the NHL subtype of PIOL [22], and found a small proportion of Th17 cells, defined as CD4+IL-17+IFNγ+ or IFNγ− T cells in the human lymphoma microenvironment. The gene discussed is CD4; the disease is diffuse large B-cell lymphoma.
