Among lymphoid cells, there were few B cells while natural killer (NK) cells were significantly enriched in YR1.7 tumors; among tumor-infiltrating T-lymphocytes (TILs), CD8 T cells, conventional CD4+Foxp3− T cells (Tconv) and CD4+Foxp3+CD25+ regulatory T cells (Tregs) were present at similar frequencies in both models (Figure 3a and Figure S3b). The gene discussed is CD4; the disease is neoplasm.
