免疫学免疫学免疫学
细胞生物学细胞生物学

背景情况:

T-树突细胞 (T_DC) 拥有T细胞和树突细胞 (DC) 的标记物和功能.
它们的确切生理作用尚不清楚,部分原因是T_DC识别的CD11c标志物不可靠.

研究的目的:

用Zbtb46-GFP记者小鼠在各种组织中研究T_DC的频率和局部化.
描述T_DC的基因表达特征,并将其与传统的T细胞和DC细胞进行比较.
探索T_DC在免疫反应中的潜在作用,特别是在病毒感染期间.

主要方法:

使用Zbtb46-GFP记者小鼠进行T_DC识别和隔离.
在排序的T_DC上进行RNA测序,以分析基因表达.
在稳定状态和病毒感染条件下,检查了T_DC分布在二级淋巴体器官 (SLOs),肝脏和肺部.

主要成果:

Zbtb46-GFP记者小鼠能够在SLOs,肝脏和肺部的T_DC在现场识别.
RNA测序证实了T_DC的独特基因特征,使它们与传统的T细胞和DC区别开来.
病毒感染后SLOs的T_DC数显著增加,表明了动态反应.

结论:

Zbtb46-GFP 报告模型为可视化和研究 T_DC.提供了一个强大的策略.
T_DC存在于多种组织中,并且它们的频率在病毒感染期间发生变化.
使用这种模型进行进一步的研究可能会阐明T_DC在感染,癌症和其他病理方面的生理功能.

Reporter Genes

Reporter Genes

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.
