The effection of everolimus on hamster-to-rat concordant heart xenotransplantation [PDF]
, 2016 背景：器官移植是解决很多终末期疾病最有效的手段，然而器官短缺限制着器官移植术的推广。异种移植是最有可能快速解决器官短缺问题的途径之一。虽然异种移植的超级性排斥反应已经因分子生物学技术的应用而极大减轻，但异种移植的急性排斥反应、延迟性排斥反应等仍旧没有克服。新型免疫抑制剂的开发可能有助于克服这些类型的免疫排斥反应。依维莫司是雷帕霉素衍生物，是一种可用于抗移植排斥的免疫抑制药物，动物实验和临床资料表明它可延长同种器官移植物生存期。依维莫司对免疫系统具有多种调节作用 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

Zhongguo shiyan zhenduanxue, 2013 肺癌是严重威胁人类生命健康的常见恶性肿瘤,它的发生、进展和转移等与机体的细胞免疫机能密切相关。细胞免疫是机体抗肿瘤免疫的重要机制,细胞免疫应答主要是T细胞介导的特异性细胞免疫[1]。T淋巴细胞是机体免疫系统内功能最重要的一大细胞群,同时又是一个复杂的细胞群体。T细胞和NK细胞在免疫监视、杀伤靶细胞及免疫调节方面具有极其重要的作用。正常情况下,T细胞及亚群的数目处于相对平衡状态,免疫功能稳定。若T细胞总数或者CD4+/CD8 ...

HUVECs Promote the Proliferation of iPS-MSCs by FAM3B [PDF]
, 2016 间充质干细胞（mesenchymalstemcells，MSCs）存在于一个血管周微环境中，在这个微环境内，内皮细胞（endothelialcells，ECs）与MSCs互相作用，调控MSCs的表型和增殖，从而在MSCs的血管生成作用和治疗应用方面起重要作用。然而，MSCs受到来源、年龄、健康等多方面的影响，不能满足大规模的使用需求。诱导多能干细胞来源的间充质干细胞（inducedpluripotentstemcell-derivedMSCs，iPS-MSCs）可能会是一个有前景的替代性干细胞来源。但是，
