Glucagon-like peptide-2 exhibits protective effect on hepatic ischemia-reperfusion injury in rats

Glucagon-like peptide-2 (GLP-2) has potent anti-inflammatory effects and protects against experimental ischemia/reperfusion (I/R) injury in pulmonary, intestinal, and myocardial tissue. However, its protective abilities against I/R injury in the liver are unknown. We investigated the potential role of GLP-2 pretreatment on hepatic I/R injury in rats. A total of 24 rats were randomly divided into three groups (n = 8). The first group was the control group; the second group was the vehicle-treated hepatic ischemia/reperfusion (HIR, vehicle saline-treated) group; and the third group was the GLP-2 pretreated I/R (GLP2-IR) group. Each rat in the third group was intraperitoneally administered 5 μg GLP-2 for 5 d before the procedure. A portal triad was created to induce ischemia with a vascular atraumatic clamp. After 40 min, the clamp was released to initiate hepatic reperfusion for 6 h. Blood samples and tissue specimens from the liver were obtained. Alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels significantly increased in the saline-treated HIR group (P<0.001), whereas GLP-2 pretreatment significantly decreased their levels (P<0.01). Our data suggested that GLP-2 pretreatment may have a protective effect on liver I/R injury. However, dose-response studies are necessary to determine the most effective dose.

蛋白质在固体表面的吸附过程涉及诸多复杂的分子间相互作用,因此到目前为止仍然无法做到精准调控。通过模拟计算,可以获取固-液界面分子尺度的蛋白质移动机理,从而为预测蛋白质吸附和结垢现象提供可靠的理论依据。本研究通过多尺度粗粒化模型对多条疏水的丙氨酸十二肽在金表面的聚集和吸附过程进行了分析。大约有一半(46.6%)的丙氨酸十二肽可以组成聚集体。30.0%的独立肽链会被快速地吸附到固体表面。这些在表面吸附的肽链经过一段时间的爬行,其中的一些(51.0%)能与吸附在表面的或是游离在溶液中的肽链融合,从而形成吸附在表面的聚集体。这些在固-液界面吸附的肽链使得固体表面性质发生变化。这一变化可能会进一步影响之后溶液中肽链和聚集体在金表面的吸附。本研究揭示的多条肽链吸附机理有希望为进一步研究多个蛋白质分子在固体表面的吸附机理提供理论基础。

由于缺乏经证实具备免疫原性的多肽,基于肿瘤抗原的免疫治疗应用受到限制。在本研究中,利用肝胆肿瘤类器官分析了环状RNA(circRNA)作为肿瘤抗原肽新来源的潜力。使用RNA测序(RNA-seq)和基于算法的评分工具,预测出27 个类器官中3950 个肿瘤特异性circRNA 可翻译18 971 条抗原肽。抗原图谱显示,11 个氨基酸长度(mer)的肽和人类白细胞抗原(HLA)-A结合肽的免疫原性相关评分最高。通过对5 个类器官进行基于质谱的免疫肽组学分析,直接证实其中三个类器官的13 条抗原肽为HLA-A、HLA-B 和HLA-C(HLA-ABC)结合肽。通过流式细胞仪和酶联免疫分析发现,HLA-ABC 呈递的cricRNA来源肿瘤特异性肽可以刺激CD8 T细胞,使其CD107a 和干扰素γ(IFNγ)共表达提高、IFNγ分泌增加。细胞杀伤实验证实,经circRNA 来源免疫原性肽活化的T 细胞可杀伤类器官细胞。值得注意的是,来自circTBC1D15 的抗原肽YGFNEILKK不仅可以被HLA-ABC呈递,还能活化T细胞,显著降低肿瘤类器官活率。本研究的发现提供了一种产生肿瘤抗原的重要来源,提示肿瘤特异性circRNA 可作为抗肿瘤靶点。
