Interestingly, the CXCL13+ CD8-Tterm.ex cluster displayed the highest clonality score among all CD8+ T cell clusters, as quantified by the STARTRAC clonal expansion index (25) (Figure 2D and Supplemental Figure 2C), likely reflecting the presence of clonally expanded, tumor antigen–specific T cell clones. The gene discussed is CXCL13; the disease is neoplasm.
