Based on an investigation of a mouse glioblastoma model, Zhao et al. [57] suggested that T cells expressing fibrinogen-like-2-specific single-chain variable fragments can increase the number of tumor-specific CD69+CD8+ memory T cells by binding to CXCL9, CXCL10, and CXCR3, as well as activating downstream pathways. Here, CXCL9 is linked to neoplasm.
