IL7R and KLF2 contribute to maintaining T cell quiescence,[23, 24] while ENTPD1, ITGAE, and PDCD1 are markers of tumor‐reactive T cells.[18, 25, 26] Gene trajectory analysis indicated that CXCL13 expression was initially low but significantly increased during cell development, whereas IL7R and KLF2 showed opposite expression patterns (Figure 5H). Here, PDCD1 is linked to neoplasm.
