在本研究中,我们研究了nAChRα3、α4、β2和β4亚单位mRNAs在大鼠中枢神经系统和三叉神经节产前和围产期发育过程中的解剖分布模式。人们已经认识到三种主要的发展模式。(1)在大多数被研究的病例中(脑、脊髓、背根神经节、三叉神经节和膝状神经节)最初都能检测到所有四个亚单位的mRNAs(E11-13),但在随后的产前发育中,其中一些亚单位的mRNAs水平变得不可检测到(脑和脊髓中的α3和β4,背根神经节中的α4和β4,内脏感觉神经节中的α4,躯体感觉神经节中的α3、α4和β4)。(2)在大脑皮层的情况下,一对亚单位mRNAs(α3-β2)最初被表达(E12-13),随后抑制α3亚单位(E15),随后(E17-19)诱导α4亚单位。(3)在视网膜(α3-α4-β2-β4)、副交感或交感运动节(α3-β2-β4)和前庭-耳蜗神经节(α4-β2)中,只有部分亚单位(E13-15)最初表达,并且在出生前和出生后早期保持稳定水平。总体而言,在大多数中枢和外周结构中,nAChR亚单位mRNAs的出现是早熟的,并且与神经元分化的时间相关。此外,在一些结构中,某些亚基(α3、α4或β4)的表达是短暂的,尽管不是β2。最后,不同区域分布模式的比较表明,有限数量的结构特异性受体亚型在中枢神经系统和三叉神经节的发育过程中具有功能。
In the present study we have investigated the anatomical distribution pattern of nAChR alpha 3, alpha 4, beta 2, and beta 4 subunit mRNAs during prenatal and perinatal development of the rat CNS and PNS. Three main developmental patterns have been recognized. (1) In the majority of cases studied (caudal brain, spinal cord, dorsal root ganglia, trigeminal and geniculate ganglia) all four subunit mRNAs are initially (E11–13) detected but, during subsequent prenatal development, the level of some of these subunit mRNAs (alpha 3 and beta 4 in the brain and spinal cord, alpha 4 and beta 4 in the dorsal root ganglia, alpha 4 in the visceral sensory ganglia, and alpha 3, alpha 4, and beta 4 in the somatic sensory ganglia) become undetectable. (2) In the case of the cerebral cortex a pair of subunit mRNAs (alpha 3-beta 2) is initially (E12–13) expressed followed by a repression of the alpha 3 subunit (E15) and the subsequent (E17–19) induction of the alpha 4 subunit. (3) Only some subunit mRNAs are initially (E13–15) expressed in the retina (alpha 3-alpha 4-beta 2-beta 4), parasympathetic or sympathetic motor ganglia (alpha 3-beta 2-beta 4), and vestibulo- cochlear ganglia (alpha 4-beta 2) and their level remains stable throughout prenatal and early postnatal development. Overall, in most central and peripheral structures the appearance of nAChR subunit mRNAs is precocious and temporally related to the timing of neuronal differentiation. In addition, in several structures the expression of certain subunits (alpha 3, alpha 4 or beta 4) is transient, although not beta 2. Finally, the comparison of the different regional distribution patterns suggests that a limited number of structure- specific receptor isoforms are functional during development of CNS and PNS.
