Nevertheless, at endpoint, CXCL10-expressing tumours showed significantly higher infiltration of total human leukocytes (p = 0.049) and CAR T cells (p = 0.01) (Fig. 7i, and Supplementary Fig. 31), indicating enhanced immune recruitment and CAR T cell trafficking driven by localized CXCL10 expression. Here, CXCL10 is linked to neoplasm.
