HiRet
Also known as: HiRet vectors, lentiviral system for highly efficient retrograde gene transfer
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
HiRet is a lentiviral system for highly efficient retrograde gene transfer that targets specific neural circuits. It supports neural circuit-selective, stable transgene expression and has been used with optogenetic tools to manipulate neuronal activity and behavior.
Usefulness & Problems
Why this is useful
HiRet is useful for delivering genes to neurons defined by their projection patterns rather than only by local injection site. In the cited use context, this enables circuit-selective transgene expression and supports optogenetic interrogation of neuronal activity and animal behavior with high spatial and temporal precision.
Problem solved
HiRet addresses the problem of introducing transgenes into specific neural circuits with stable expression. The cited literature specifically positions it as a way to achieve neural circuit selectivity for subsequent functional manipulation.
