小鼠主嗅上皮中的单个嗅觉感觉神经元(OSN)表达来自I类或II类气味受体(OR)库的单个OR基因。转录因子Bcl 11b决定OSN中表达的OR类。鼻中隔器(SO)是位于鼻中隔腹侧基底的一个小的神经上皮,被认为是嗅觉子系统,因为它表达了一个特定的OR亚群。然而,SO-OSN的产生和分化的机制仍不清楚。在本研究中,我们表明,生成和分化的SO-OSN采用相同的遗传途径,在OSN谱系,这是由神经元命运决定因子Ascl 1启动。此外,Bcl 11b缺陷小鼠的异常表型证明了Bcl 11b在SO中的关键作用:OR基因的表达和成熟SO-OSN的数量显着减少。尽管SO-OSN在野生型小鼠中表达II类OR基因的一个子集,但Bcl 11b缺失导致I类OR基因的表达,而II类OR基因的表达显著降低,Olfr 15除外。这些结果表明Bcl 11b是SO-OSNs中OR正确表达所必需的。
Individual olfactory sensory neurons (OSNs) in the mouse main olfactory epithelium express a single odorant receptor (OR) gene from the repertoire of either class I or class II ORs. The transcription factor Bcl11b determines the OR class to be expressed in OSNs. The septal organ (SO), a small neuroepithelium located at the ventral base of the nasal septum, is considered as an olfactory subsystem because it expresses a specific subset of ORs. However, the mechanisms underlying the generation and differentiation of SO-OSN remain unknown. In the present study, we show that the generation and differentiation of SO-OSN employ the same genetic pathway as in the OSN lineage, which is initiated by the neuronal fate determinant factor Ascl1. Additionally, the key role of Bcl11b in the SO is demonstrated by the abnormal phenotypes ofBcl11b-deficient mice: significant reduction in the expression of OR genes and in the number of mature SO-OSNs. Although SO-OSNs are specified to express a subset of class II OR genes in wild-type mice, theBcl11bdeletion led to the expression of class I OR genes, while the expression of class II OR genes was significantly decreased, with one exception ofOlfr15. These results indicate that Bcl11b is necessary for proper OR expression in SO-OSNs.
