使用PEPscreen®多肽研究AAV-hF.IX基因治疗的CTL MHC I类和Th II类免疫应答

重组腺相关病毒(AAV)载体介导的人凝血因子IX(hF.IX)表达基因治疗是一种前景可期的基因转移策略，因其使用肝脏特异性启动子，可实现hF.IX在肝脏中的长期表达和弱免疫应答。但在人类和某些动物中，F.IX表达会随着时间推移而下降，并且载体和转基因会诱发免疫应答。

Lipopolysaccharides

Lipopolysaccharides (LPS) are characteristic components of the cell wall of Gram negative bacteria; they are not found in Gram positive bacteria. They are localized in the outer layer of the membrane and are, in noncapsulated strains, exposed on the cell
