...AAV8, AAV9 Table 1: Summary of tissue tropism displayed by different AAV serotypes. Pseudotypes Pseudotyping...derived from eight different serotypes. AAV-DJ displays a higher transduction efficiency in vitro than...specific cell and tissue types, like AAV-DJ8, which displays enhanced brain uptake. Systemic capsids Another...employed to engineer an rAAV serotype variant able to display neuronal retrograde transport, AAVrg. Retrograde...limitation for CRISPR delivery for more information. Split AAVs to increase packaging capacity Another strategy...derived plasmids and base/prime editors, is to create split AAVs. Here, a longer transgene is broken down between...different mechanisms. One of these methods uses splice site donor and acceptor sequences to reconstitute...
