Abstract

How is the brain so efficient at excluding proteins, drugs, and immune cells from the blood? In this issue of Neuron, Ayloo et al. (2022) find that an extracellular matrix protein secreted by CNS pericytes shuts down endocytic transport in blood brain barrier endothelial cells.

摘要

大脑是如何高效地将蛋白质、药物和免疫细胞从血液中排除出去的?在本期《神经元》杂志上,Ayloo 等人(2022)发现,一种由中枢神经系统周细胞分泌的细胞外基质蛋白会使血脑屏障内皮细胞中的内吞运输失活。
