We observed no variations in the prevalence of other immune cell types among total BALF CD45+ cells, including CD3+CD8+ T cells, CD3+CD4+ T cells, CD20+ B cells, CD3+CD4+CD8+ T cells or Lin−HLA−DR+ cells, in both WTM and OM compared to HC (Extended Data Fig. 4f). This evidence concerns the gene CD8A and ocular melanoma.
