目的

分析Toll样受体4(TLR4)蛋白在小鼠小脑组织中的表达情况。

方法

选取6月龄大小的TLR4基因敲除(TLR4-/-)小鼠及其同窝对照的野生型(TLR4+/+)小鼠的小脑组织,制成冰冻切片,通过免疫荧光染色技术检测TLR4在TLR4+/+小鼠小脑冰冻切片组织中的表达,并利用小脑组织特定细胞的蛋白标记Marker与其共染,TLR4-/-小鼠小脑冰冻切片作为阴性对照,最后通过激光共聚焦显微镜获取图像并确定TLR4在小脑组织中的表达。

结果

TLR4高表达于钙结合蛋白阳性的小脑蒲肯野细胞中,少量表达于离子钙接头蛋白阳性的小胶质细胞中,而在性别决定区Y盒2号蛋白阳性的伯格曼胶质细胞和神经元特异核蛋白阳性的颗粒细胞中并无表达。

结论

TLR4高表达于小鼠小脑蒲肯野细胞中,深入分析TLR4在蒲肯野细胞功能执行中的作用,将有助于揭示TLR4在小脑功能执行中的作用。

Objective

To analysis the expression of Toll-like receptor 4 (TLR4) in mouse cerbellum.

Methods

Fronze sections gained from the 6 months old TLR4 knockout (TLR4-/-) mice and wildtype littermates (TLR4+/+). Co-stained TLR4 with cerebellar special cells markers by immunofluorescence technology in frozen sections and revealed TLR4 localization by laser confocal scanning.

Results

TLR4 is highly expressed in Purkinje cell but not in Bergamnn glia or cerbellar granule cells. In addition, there were few microglia expressing TLR4 in cerebellum.

Conclusion

TLR4 is highly expressed in cerebellar Purkinje cell and it is beneficial for revealed its function in cerebellum by analyzing the role of TLR4 on Purkinje cell function.
