Furthermore, CXCL10 levels were elevated in meningeal pericytes and fibroblasts in T-ALL mice relative to their counterparts in other tissues and organs, further supporting a unique role for the meningeal microenvironment in driving CXCL10 induction in response to T-ALL (Figure 5, K and L, and Supplemental Figure 5, N and O). The gene discussed is CXCL10; the disease is acute lymphoblastic leukemia.
