哺乳动物海马层特异性传入神经支配对其功能至关重要。我们研究了化学驱除素与三种主要海马传入神经的层状投射的相关性:苔藓纤维、内嗅纤维和关联/连合纤维。我们观察到,地草素缺乏会导致苔藓纤维的异常投射,但不会导致其他传入神经的异常投射。免疫组织化学分析表明,draxin 在出生后第 0 天的齿状回和角 (CA) 3 中表达,此时齿状颗粒细胞开始向 CA3 延伸苔藓纤维。此外,使用新生儿齿状回分离细胞进行的神经突生长测定表明,draxin 在体外抑制表达 calbindin-D28k 的苔藓纤维的生长。综上所述,我们得出结论,draxin 是调节苔藓纤维投射的关键分子。
Lamina-specific afferent innervation of the mammalian hippocampus is critical for its function. We investigated the relevance of the chemorepellent draxin to the laminar projections of three principal hippocampal afferents: mossy fibers, entorhinal, and associational/commissural fibers. We observed that draxin deficiency led to abnormal projection of mossy fibers but not other afferents. Immunohistochemical analysis indicated that draxin is expressed in the dentate gyrus and cornu ammonis (CA) 3 at postnatal day 0, when dentate granule cells begin to extend mossy fibers towards CA3. Furthermore, a neurite growth assay using dissociated cells of the neonatal dentate gyrus revealed that draxin inhibited the growth of calbindin-D28k-expressing mossy fibersin vitro. Taken together, we conclude that draxin is a key molecule in the regulation of mossy fiber projections.
