[Abstract] Neutralizing antibodies (Nabs) are a major challenge in clinical trials of adeno-associated virus (AAV) vector gene therapy, because Nabs are able to inhibit AAV transduction in patients. We have successfully isolated several novel Nab-escaped AAV chimeric capsids in mice by administrating a mixture of AAV shuffled library and patient serum. These ...
Establishment of a Human Cell Line Persistently Infected with Sendai Virus
[Abstract] Interferon regulatory transcription factor 3 (IRF3) is a transcription factor that upon activation by virus infection promotes the synthesis of antiviral genes, such as the interferons (Hiscott, 2007). In addition to inducing genes, IRF3 triggers antiviral apoptosis by RIG-I-like receptor-induced IRF3 mediated pathway of apoptosis (RIPA), which is ...
Ribosomal RNA N-glycosylase Activity Assay of Ribosome-inactivating Proteins
[Abstract] Ribosome-inactivating proteins (RIPs) are enzymes that irreversibly inactivate ribosomes as a consequence of their N-glycosylase (EC 3.2.2.22) activity. The enzyme cleaves the N-glycosidic bond between the adenine No. 4324 from the 28S rRNA and its ribose in rat ribosomes (or the equivalent adenine in sensitive ribosomes from other organisms). ...
