目的
2
揭示靶向抑制生长分化因子3(GDF3)对脉络膜新生血管(CNV)形成及内皮炎症反应的影响。
方法
2
构建激光诱导的小鼠CNV模型,通过RNA测序(RNA-seq)筛选差异基因。采用实时荧光定量PCR(RT-qPCR)和Western blot验证GDF3表达水平。通过siRNA及中和抗体拮抗内皮细胞GDF3,采用CCK8实验、划痕实验及成管实验评估内皮细胞增殖、迁移和血管生成能力。检测炎症/黏附分子表达变化,分析免疫细胞黏附和跨内皮迁移实验变化。在CNV模型中,通过玻璃体腔注射shRNA靶向抑制GDF3,结合免疫荧光染色观察CNV面积及免疫细胞浸润情况。
结果
2
GDF3在CNV组织中表达显著上调(
P
<0.001)。体外干预GDF3显著抑制内皮细胞增殖(
P
<0.001)、迁移(
P
<0.001)及血管生成能力(
P
<0.01),同时下调炎症/黏附分子表达(
P
<0.001),并显著减少免疫细胞黏附(
P
<0.001)和跨内皮迁移(
P
<0.001)。体内实验证实靶向抑制GDF3可显著抑制CNV的形成(
P
<0.001)并降低免疫细胞浸润(
P
<0.001)。
结论
2
靶向抑制GDF3可协同抑制内皮炎症反应和病理性血管生成,其作用可能与调控炎症微环境相关,为湿性年龄相关性黄斑变性(wAMD)治疗提供新思路。
Objective
2
To investigate the effects of targeted inhibition of growth differentiation factor 3 (GDF3) on choroidal neovascularization (CNV) and endothelial inflammatory response.
Methods
2
A laser-induced CNV mouse model was established, and differentially expressed genes were screened by RNA sequencing (RNA-seq). GDF3 expression was validated by real-time fluorescence quantitative PCR(RT-qPCR) and Western blot. GDF3 in endothelial cells was antagonized by siRNA and neutralizing antibodies. Functional assays including CCK8 assay, scratch assay, and tube formation assay were performed to assess endothelial cell proliferation, migration, and angiogenic capacity. The expression changes of inflammatory/adhesion molecules were measured, and immune cell adhesion and transendothelial migration were analyzed. In the CNV model, shRNA was intravitreally injected to suppress GDF3 expression, with CNV lesions and immune cell infiltration quantified by immunofluorescence staining.
Results
2
GDF3 expression was significantly upregulated in CNV tissues (
P
<0.001). In vitro GDF3 intervention markedly suppressed endothelial cell proliferation (
P
<0.001), migration (
P
<0.001), and angiogenesis (
P
<0.01), downregulated the expression of inflammatory/adhesion molecules (
P
<0.001), and significantly reduced immune cell adh
esion (
P
<0.001) and transendothelial migration (
P
<0.001). In vivo experiments confirmed that targeted inhibition of GDF3 significantly attenuated CNV formation (
P
<0.001) and decreased immune cell infiltration (
P<
0.001).
Conclusion
2
Targeted inhibition of GDF3 concurrently attenuates endothelial inflammatory response and pathological angiogenesis, potentially through modulating the inflammatory microenvironment. These findings provide novel insights for the treatment of wet age-related macular degeneration (wAMD).
