Arachnoid cell involvement in the mechanism of coagulation-initiated inflammation in the subarachnoid space after subarachnoid hemorrhage     

Zhao-liang Xin  Xiao-kang Wu  Jian-rong Xu  Xi Li 《Journal of Zhejiang University. Science. B》2010,11(7):516-523

Objective: To assess if arachnoid cells have the capability to present antigen and activate T-lymphocytes after stimulation by bloody cerebrospinal fluid (CSF), and to illuminate the mechanism of coagulation-initiated inflammation in the subarachnoid space after subarachnoid hemorrhage (SAH). Methods: Arachnoid cells were cultured, characterized, and examined by immunofluorescence for the basal expression of human leukocyte antigen-DR (HLA-DR). Expression of HLA-DR, after co-culturing arachnoid cells in vitro with bloody CSF, was investigated by immunofluorescence and flow cytometry (FCM). The variation of arachnoid cells' ultrastructure was observed by transmission electron microscope (TEM). Arachnoid cells were co-cultured with peripheral blood mononuclear cells (PBMCs). The content of soluble interleukin-2 receptor (sIL-2r) in culture medium was detected by enzyme-linked immunosorbent assay (ELISA). Results: (1) Arachnoid cells were successfully cultured for many passages. The immunofluorescent staining was positive for HLA-DR in over 95% of the human arachnoid cells. The punctate HLA-DR was distributed in cytoplasm and not in the karyon. (2) After co-culturing arachnoid cells in vitro with bloody CSF, numerous particles with strong fluorescence appeared in the cytoplasm on Day 6. On Day 8, the quantity of particles and fluorescent intensity were maximal. FCM showed that the percentage of HLA-DR expressing cells was (2.5±0.4)% at the first 5 d, increasing to (60.8±3.6)% on Day 7. (3) After co-culturing arachnoid cells in vitro with bloody CSF, many lysosome and secondary lysosome particles were present in the cytoplasm. Hyperplasia of rough endoplasmic reticulum and enlarged cysts were observed, with numerous phagocytizing vesicles also observed at the edge of the arachnoid cells. (4) Arachnoid cells stimulated by bloody CSF were co-cultured in vitro with PBMCs. The content of sIL-2r in the culture medium, having been maintained at around 1.30 ng/ml during the first 3 d, had increased by Day 4. The content of sIL-2r peaked 7.53 ng/ml on Day 7 and then reduced gradually. Conclusions: (1) Basic HLA-DR expression is present in arachnoid cells. (2) After stimulation by bloody CSF, arachnoid cells have the potential to serve as antigen presenting cells (APCs) and the ability to activate T-lymphocytes, indicating that arachnoid cells are involved in the mechanism of coagulation-initiated inflammation in the subarachnoid space after SAH.  相似文献

论《聊斋志异》中狐意象的文化意蕴     

唐莉 《甘肃高师学报》2008,13(6):42-45

中国古代小说中的狐意象,源于远古时期先民的图腾崇拜意识。两汉时期,它呈现出瑞兽和妖兽的双重身分。从六朝到唐代,狐在被神化和妖化的同时,也不断地在向人的方向发展,逐渐获得人的外形和气质。到了明清时期,文学作品中狐的形象和内涵更加丰富多彩,其反映社会生活的广度和深度也达到前所未有的程度。尤其《聊斋志异》中具有人形美、人性美、人情美的狐意象,既是作者寄托情感、慰藉心灵、超越现实、实现生命价值的载体,更是那个时代社会、文化状况的反映。  相似文献

康脑液对皮质区干细胞因子基因表达的影响     

潘妍婷  邹玉安 《河北北方学院学报(医学版)》2008,25(3)

目的:在康脑液方剂干预下观察皮质区内源性神经细胞干细胞因子(SCF)mRNA在大鼠脑缺血再灌注损伤后不同时间的表达情况。方法:成年SD大鼠,以线栓法建立大脑中动脉缺血再灌注模型,随机分为模型组、药物干预组和假手术组。原位杂交技术检测脑缺血1.5h再灌注1～14d后,脑皮质区SCFmRNA表达情况。结果:脑缺血再灌注后,药物干预组、模型组SCFmRNA的表达在皮质区均明显高于假手术组,于第7天达高峰,第14天下降。结论:药物干预后脑缺血再灌注脑皮质区SCFmRNA表达在不同时间点与模型组具备相同的表达规律,两组SCFmRNA的表达无显著性差异。  相似文献

Enhanced expression of HMG-Y proteins in proliferating tissues     

Dinesh Singh  M. R. Rajeswari 《Indian journal of clinical biochemistry : IJCB》2001,16(1):72-76

The high mobility group (HMG) proteins I and Y are well characterised non-histone chromosomal proteins which bind to A-T rich regions of DNA and regulate gene expression and/or DNA replication. A correlation has been demonstrated between the increased expression of HMG-Y proteins and malignancy. However, it is not known whether the expression of HMGs particularly, the Y group, is a function of proliferation rate. In the present study, we have used normal tissues of calf testes, thymus and liver. The results show distinctly high expression of HMG-Y proteins in testes than in thymus and the expression was practically undetectable in liver. The results suggest that even in normal tissues there is a direct correlation between the proliferation rate and the expression of the HMG-Y proteins, which can partly explain its increased expression in cancer.  相似文献
