All of these cytokines were found at high levels in the huPDX ascites samples (Table 1), including chemokines that recruit immune cells to the tumor microenvironment such as MCP-1/CCL2 that recruits monocytes (38), MDC that recruits regulatory T cells (30), and MIG1 (CXCL9) and IP-10 (CXCL10) that recruit effector memory T cells (39, 40). The gene discussed is CCL22; the disease is neoplasm.
