Moreover, IL-15 and CX3CL1 plasma levels were positively correlated with markers of inflammation and high tumor burden (fibrinogen, lactate dehydrogenase, C-reactive protein, cell-free DNA, CXCL9) at pre-lymphodepletion, a biochemical makeup that has been associated with ICANS (14, 20). The gene discussed is CXCL9; the disease is neoplasm.
