AAV-BR1血脑屏障(blood-brain barrier,BBB)是中枢神经系统(central nervous system,CNS)中独特而复杂的多细胞屏障结构.BBB主要由脑微血管内皮细胞(endothelial cell,EC),周细胞,基膜,星形胶质细胞的脚板等组成.BBB作为血液与脑组织之间的屏障结构,为CNS的发育和稳态提供稳定的环境.BBB完整性的丧失促进神经毒素,血浆...
After intravenous injection of AAV-BR1-sgCtnnb1-tdTomato in 4-week-old Tie2Cas9 transgenic mice resulted in mutation of 36.1% of the Ctnnb1 alleles, thereby leading to a dramatic decrease in the level of CTNNB1 in brain ECs. Consequently, Ctnnb1 gene editing in brain ECs resulted in ...

首次使耳聋患者的听力恢复 | 常染色体隐性耳聋9是由OTOF基因突变引起的,其特征是先天性或语前,严重到完全的双侧听力损失。然而,目前还没有药物治疗先天性耳聋。该研究报道了携带人类OTOF基因(AAV1-hOTOF)的1型腺相关病毒(AAV)基因治疗儿童常染色体隐性耳聋的安全性和有效性(国际首个先天性耳聋基因治疗临床试验)。
【帕金森病基因疗法获FDA授予再生医学先进疗法认定】北京时间2025年2月20日,拜耳(Bayer)的基因治疗子公司AskBio宣布,用于治疗帕金森病的在研基因疗法AB-1005已获得美国FDA授予的再生医学先进疗法(RMAT)认定。AB-1005是旨在减缓帕金森病情进展并改善患者运动结果的试验性基因疗法。 帕金森病是一种渐进性神经退行性疾病,对...
(BBB). Several approaches have been used to overcome this hindrance to facilitate the treatment of various CNS diseases. We now present results showing that chimeric adeno-associated virus 2/1 (AAV2/1) particles containing the coding region for the LacZ gene are efficiently delivered into the ...
AAV-BR1Cx43 gap junctionsendothelial cellsretinaEndothelial cells (ECs) are key players in the development and maintenance of the vascular tree, the establishment of the blood–brain barrier and control of blood flow. Disruption in ECs is an early and active component of vascular pathogenesis. ...
AAV-BR1-NPC2 treatment partially normalized these ganglioside distributions in high responders, including restoration of lipid profiles towards those of Npc2 / controls. Conclusion: The data suggests cross-correcting gene therapy to the brain via delivery of NPC2 from BECs and neurons....
在hPD-1/PD-L1 AAV-HBV小鼠模型中,SA012 7.5 mg/kg QW,皮下注射8次,1/7的小鼠实现HBsAg清除,4/7的小鼠HBV DNA检测不到,5/7的小鼠HBsAb水平超40 mIU/mL;SA012联用VIR-2218 1 mg/kg Q4W,皮下注射2次,4/8的小鼠实现HBsAg清除;SA012 + VIR-2218 + SA011进一步提高了HBsAg清除率(6/8)及HBV ...
医麦客,赛默飞的名单 | 图1-2.第一,医麦客说,美国企业用AAV转染神经细胞,防止Tau聚集和病毒的感染。这个预期,是过度乐观的!首先,要是AAV自身,引发中和抗体,都会结合AAV蛋白,有效攻击粘附在脑细胞的AAV蛋白分子。这种情况,会把脑部变成第二战场,包括抗体直接引导杀伤脑细胞。其次,用zfn敲除的话,与病毒的关系不大...
