Analysis of RNAseq data from the TCGA melanomas established that mRNAs encoding the CD8 T cell markers CD8a and CD8b, the CD47-dependent T cell activation markers CD69 and TNFα, and all of the above regulators of CD8 T cell function have strong positive correlations with CD47 mRNA expression (Table 1). The gene discussed is CD8B; the disease is melanoma.
