For lymphoid populations, there was a trend of an increase in number of tumour infiltrating lymphocytes (CD3+ T, CD4+ T, CD8+ T, and B cells) per gram of tumour (Fig. 5A, Supplementary Fig. S8A), although the CD8+ T cells had a comparable frequency of memory cells in both treatment groups (Supplementary Fig. S9). The gene discussed is CD4; the disease is neoplasm.
