As expected, the vast majority of SIINFEKL+ CD8+ T cells in the tumor expressed CD69 and lacked CD62L (Figure 2e and f), with a fraction of CD69+ cells co‐expressing CD103 (Figure 2g and h), a marker associated with tissue residency that is lacking on circulating CD44+ T cells.22 The gene discussed is ITGAE; the disease is neoplasm.
