摘要
目的研究组织蛋白酶B(CB)在正常SD大鼠胰腺中的表达,为进一步研究应用CB抑制剂治疗急性胰腺炎提供形态学依据。方法应用免疫荧光组织化学双重标记技术,在激光共聚焦显微镜下观察CB在正常SD大鼠胰腺中的分布。结果 CB免疫反应阳性细胞分布在胰岛的A细胞、B细胞、D细胞及PP细胞,阳性物质分布于细胞质,细胞核阴性。结论 CB在SD大鼠胰腺的表达,提示CB可能在胰腺起着非常重要的作用。
Objective To investigate the distribution of cathepsin B(CB) in the pancreas of normal SD rat to provide morphologic basis for further research on using CB inhibitor to cure acute pancreatitis.Methods The present study used immunofluorescence histochemical double-labeling technique to observe the localization of CB in the pancreas of normal SD rats under a confocal laser-scanning microscope.Results CB immunoreactivity localized in the glucagon-secreting cells(A cells),insulin-secreting cells(B cells),somatostatin-secreting cells(D cells),and pancreatic polypeptide(PP)-secreting cells(PP cells).They were found regularly in the cytoplasm,but not in the nucleus.Conclutions The results indicate that CB may play a critical role in the pancreas.
