先天免疫的人类单核细胞/巨噬细胞 (M/MФ) 通过与刺激性(如 TLR)和抑制性(如 Tim-3)受体偶联的特定受体来感知和响应微生物产物。目前的模型表明,M/MØ 上的 Tim-3 表达可以通过与其他细胞呈递的配体 Galectin-9 (Gal-9) 反式关联,向 TLR 介导的 IL-12 表达传递负信号。然而,Gal-9也在M/MØ内表达,并且细胞内Gal-9对同一M/MØ中Tim-3活性和炎症反应的影响仍不清楚。在这项研究中,我们的数据表明,Tim-3 和 IL-12/IL-23 基因转录是通过与 TLR 信号协同作用,通过单核细胞内 Gal-9 表达的增强或沉默来调节的。此外,TLR 激活促进同一 M/MØ 内的 Gal-9/Tim-3 顺式关联,通过 STAT-3 磷酸化差异调节 IL-12/IL-23 表达。这些结果揭示了通过 TLR 途径对受体 (Tim-3) 活性和炎症反应产生配体 (Gal-9) 区室依赖性调节作用,这是细胞对外部或内部信号做出反应的一种新机制。
Human monocytes/macrophages (M/MФ) of the innate immunity sense and respond to microbial products via specific receptor coupling with stimulatory (such as TLR) and inhibitory (such as Tim-3) receptors. Current models imply that Tim-3 expression on M/MØ can deliver negative signaling to TLR-mediated IL-12 expression through trans association with its ligand Galectin-9 (Gal-9) presented by other cells. However, Gal-9 is also expressed within M/MØ, and the effect of intracellular Gal-9 on Tim-3 activities and inflammatory responses in the same M/MØ remains unknown. In this study, our data suggest that Tim-3 and IL-12/IL-23 gene transcriptions are regulated by enhanced or silenced Gal-9 expression within monocytes through synergizing with TLR signaling. Additionally, TLR activation facilitates Gal-9/Tim-3 cis association within the same M/MØ to differentially regulate IL-12/IL-23 expressions through STAT-3 phosphorylation. These results reveal a ligand (Gal-9) compartment-dependent regulatory effect on receptor (Tim-3) activities and inflammatory responses via TLR pathways—a novel mechanism underlying cellular responses to external or internal cues.
