将基因工程细胞移植到大脑中,作为许多药物的输送系统,前景广阔。发展这项技术的进展应该是迅速的,因为这些技术现在是可用的,并且潜在的临床应用或对大脑功能基本原理的研究的理由是明确的。对于植入的细胞应该如何发挥功能的期望对于每个实验范式都是不同的,并且在许多情况下,作用机制是未知的。植入细胞的可能功能包括输送营养或嗜性分子、分泌神经递质或激素、突触介导的神经递质释放,以及充当再生轴突从病变近端生长到远端的桥梁。对适合植入的细胞的类型和年龄的限制取决于植入后长期SUT存活和有用功能的要求。胎儿神经元组织已被证明是脑移植最成功的供体组织,在许多情况下,成功是戏剧性的和明确的。然而,细胞的数量和神经元表型的纯度是限制性变量。此外,移植物存活和功能可能需要免疫抑制。最后,关于使用胎儿组织的伦理和政治争论阻碍了这种实验方法的临床应用。
Grafting genetically engineered cells into the brain holds much promise as a delivery system for many pharmacologically active agents. Progress in developing this technique should be rapid, as the techniques are now available, and the rationale-potential clinical application or research on basic principles of brain function-is clear. The expectation of how an implanted cell should function differs for each experimental paradigm, and in many cases the mechanism of action is unknown. Among possible functions for implanted cells are delivery of trophic or tropic molecules, secretion of neurotransmitters or hormones, synaptically mediated release of neurotransmitters, and acting as a bridge for regenerating axons to grow from the proximal side of a lesion to the distal side. The restrictions on the types and ages of cells that are appropriate for implantation are dictated by the requirement for SUT-vival and useful function for extended periods following implantation. Fetal neuronal tissue has proven to be the most successful donor tissue for brain grafting, and in many cases success has been dramatic arrd unequivocal’. However, the number of cells and the purity of the neuronal phenotype are limiting variables. Furthermore, immunosuppression may be required for graft survival and function. Finally, the ethical and political debates on the use of fetal tissue hinder clinical application of this experimental approach.
