文题释义:
富细胞因子自体血清提取技术:
此技术是利用自身的血液,加以刺激的手段,通过离心方法,提取出富含细胞因子的血清的最新生物技术。大量研究和临床实验表明:提取的富细胞因子血清在缓解组织炎症方面具有显著的作用,并且操作简单、具有很高的安全性。
白细胞介素1受体拮抗物:白细胞介素1受体拮抗剂是白细胞介素1家族中的一员。在大量的动物疾病模型以及人的自身免疫性疾病和慢性炎症疾病中产生。它结合到白细胞介素1的受体上与白细胞介素1竞争结合位点,但是在这些结合不会引发胞内反应。已经有很多科研组在研究它在阻碍白细胞介素1促炎效应中所扮演的角色。

 

摘要
背景:
自体血清疗法是一种新兴的、安全的生物疗法,主要适应证是骨关节炎、风湿性关节炎等类似病症。
目的:探讨富含细胞因子的自体血清制备方法并进行细胞因子分析。
方法:采用了获得专利的采血设备(内含3 mm玻璃小珠)进行外周血采集,充分混匀后放置于37 ℃的恒温培养箱内,进行24 h的恒温孵育,最终分离过滤得到自体血清。测定白细胞介素1受体拮抗物、白细胞介素6、白细胞介素8、白细胞介素1β等细胞因子定量的浓度,并用细胞因子抗体芯片的检测方法对36种细胞因子进行了半定量测定。
结果与结论:①制备的自体血清中多种细胞因子浓度有明显增加,其中,对缓解骨关节炎病症起到关键作用的白细胞介素1受体拮抗物的质量浓度由平均140.25 ng/L增加至1 125 ng/L,增加8倍以上;白细胞介素6质量浓度由389.5 ng/L增加至2 802 ng/L,白细胞介素8由“未检测到”增加至2 822 ng/L;②采用细胞因子抗体芯片的方法检测制备的自体血清发现,至少有10种细胞因子的含量发生了改变,大部分因子的变化趋势是制备后增加,少数几个因子呈下降的趋势;③结果证明,制备的自体血清当中,含有大量的白细胞介素1受体拮抗物和多种细胞因子,另外,自体血清中还含有一部分的趋化因子,提示这些趋化因子能够招募更多的免疫细胞来到炎症部位,加快炎症反应进程,起到治疗的作用。

Abstract:

BACKGROUND: Autologous conditioned serum (ACS) is a new and safe biological therapy method mainly used for osteoarthritis, rheumatoid arthritis and other similar diseases.
OBJECTIVE: To explore the purification method and cytokine profile of ACS.
METHODS: Blood obtained equipment (containing 3 mm of glass beads) was used to collect peripheral blood samples that were mixed uniformly and then placed in a 37 ℃ thermostatic incubator for 24 hours, finally filtered to obtain ACS. The quantitative determination of interleukin (IL)-1Ra, IL-6, IL-8, and IL-1β was conducted, and the 36 kinds of cytokines were semi-quantitatively detected by cytokine antibody array.
RESULTS AND CONCLUSION: The levels of various cytokines in ACS were obviously increased, among which, IL-1Ra level (important for alleviating osteoarthritis) was increased from 140.25 ng/L to 1 125 ng/L(increased by above 8 times); IL-6 level was increased from 389.5 ng/L to 2 802 ng/L; IL-8 level was not detected firstly and finally increased to 2 822 ng/L. Cytokine antibody array results showed that at least 10 kinds of cytokines in ACS were changed, and most of cytokines were on a rise, and few in decline. These results indicate that the ACS contains IL-1Ra and a variety of cytokines, and some chemokines in the ACS recruit more immune cells to the inflammation sites and accelerate the inflammatory process, further exerting therapeutic effects.
