Delivery of therapeutics to the brain is challenging because of efflux pumps located in the vascular endothelium. A detailed analysis of Wnt signaling in a human brain endothelial cell line indicates that expression and function of P-glycoprotein, a major efflux transporter, is controlled by non-canonical Wnt signaling. Inhibition of this pathway leads to downregulation of P-glycoprotein and increased transcellular drug transport and reveals a potential strategy for improving drug delivery for treatment of neurologic diseases.
将治疗药物递送到大脑具有挑战性,因为血管内皮细胞中存在外排泵。对人脑血管内皮细胞系中 Wnt 信号的详细分析表明,主要外排转运蛋白 P-糖蛋白的表达和功能受非经典 Wnt 信号的控制。抑制该途径可导致 P-糖蛋白下调和跨细胞药物转运增加,并为改善神经疾病治疗的药物递送提供了一种潜在策略。
