中间细丝构成了一类生物聚合物,其功能仍然知之甚少。神经丝是这种中间纤维的一个例子,神经丝是填充神经元轴突的大分子。本文研究了纯化猪神经丝的重组网络,并评估了不同纳米颗粒在生物聚合物网络中的扩散行为。粒子的扩散对粒子的电荷状态有很强的依赖性,对于脂质体,也对脂质的脂肪酸构型有很强的依赖性。结果表明,静电和疏水相互作用都有助于纳米颗粒在神经丝网络中的捕获,而后者是由具有倒锥几何形状的脂质体实现的,该脂质体允许进入脂质体外壳的疏水核心。
Intermediate filaments constitute a class of biopolymers whose function is still poorly understood. One example for such intermediate filaments is given by neurofilaments, large macromolecules that fill the axon of neurons. Here, reconstituted networks of purified porcine neurofilaments are studied and the diffusion behavior of different nanoparticles in the biopolymer network is evaluated. A strong dependence of particle diffusion on the charge state of the particles, and – for liposomes – also on the fatty acid configuration of lipids is observed. The results suggest that both electrostatic and hydrophobic interactions contribute to nanoparticle trapping in neurofilament networks, and that the latter is enabled by lipids with an inverted cone geometry which grant access to the hydrophobic core of the liposome shell.
