FMRP is regulated by Myc and is highly expressed in a variety of human and mouse tumor tissues.FMRP recruits Treg and M2 macrophages to form an immunosuppressive tumor microenvironment by IL3, PROS1 and exosomes.FMRP-KO up-regulates tumor cell secretion of CCL7, which directly activates and recruits CD8+ T cells.FMRP-KO recruits CCR5 and CXCR4 receptor-positive CD8 T cells indirectly by promoting M1 macrophages to secrete CCL5, CXCL9, and CXCL10.
脆性X智力低下蛋白（FMRP）受Myc调控，在多种人类和小鼠肿瘤组织中高表达。FMRP通过白细胞介素3（IL3）、蛋白S1（PROS1）和外泌体招募调节性T细胞（Treg）和M2巨噬细胞，形成免疫抑制性肿瘤微环境。FMRP基因敲除（FMRP-KO）上调肿瘤细胞分泌趋化因子配体7（CCL7），直接激活并招募CD8+T细胞。FMRP-KO通过促进M1巨噬细胞分泌CCL5、CXC趋化因子配体9（CXCL9）和CXC趋化因子配体10（CXCL10），间接招募C-C趋化因子受体5（CCR5）和C-X-C趋化因子受体4（CXCR4）阳性的CD8 T细胞。
