本研究探讨了多巴胺受体3(D3 R)在出生后小鼠脑室下区(SVZ)的表达及其作用。原位杂交检测到SVZ中选择性D3 R mRNA表达。使用hGFAP-GFP和Dcx-GFP小鼠的成年SVZ亚型的荧光激活细胞分选(FACS)显示,转运扩增祖细胞和小生境星形胶质细胞表达D3 R,而干细胞样星形胶质细胞和成神经细胞不表达。为了确定D3 R在SVZ神经发生中的作用,我们在出生后的小鼠中施用了U-99194 A(一种D3 R优先拮抗剂)和溴脱氧尿苷(BrdU)。在体内D3 R拮抗作用的新生神经元的数量减少,达到核心和球周层的嗅球。此外,它减少祖细胞增殖,但不改变标记保留(干)细胞的数量,与其在过境扩增祖细胞上的表达相称,但不SVZ干细胞样星形胶质细胞。总的来说,这项研究表明,多巴胺能刺激D3 R驱动增殖通过快速扩增祖细胞,以促进小鼠SVZ神经发生。
We investigated the expression and role of the dopamine receptor 3 (D3R) in postnatal mouse subventricular zone (SVZ). In situ hybridization detected selective D3R mRNA expression in the SVZ. Fluorescence activated cell sorting (FACS) of adult SVZ subtypes using hGFAP-GFP and Dcx-GFP mice showed that transit amplifying progenitor cells and niche astrocytes expressed D3R whereas stem cell-like astrocytes and neuroblasts did not. To determine D3R’s role in SVZ neurogenesis, we administered U-99194A, a D3R preferential antagonist, and bromodeoxyuridine (BrdU) in postnatal mice. In vivo D3R antagonism decreased the numbers of newborn neurons reaching the core and the periglomerular layer of the olfactory bulb. Moreover, it decreased progenitor cell proliferation but did not change the number of label-retaining (stem) cells, commensurate with its expression on transit amplifying progenitor cells but not SVZ stem cell-like astrocytes. Collectively, this study suggests that dopaminergic stimulation of D3R drives proliferation via rapidly amplifying progenitor cells to promote murine SVZ neurogenesis.
