英文摘要
Project Summary:
Fundamental to furthering our understanding of the brain is the ability to longitudinally
track changes in gene expression over time in different contexts (e.g. development or
learning) (Aim 1) and to develop methods to target and manipulate specific neuronal cell
types regardless of species (Aim 2). This proposal is aimed at achieving these goals in
both genetically amenable and non-amenable species. While we anticipate that the
methodologies we will develop will be broadly useful in a multitude of contexts, we will
leverage our experience and knowledge of the specification and development of
interneurons as a means to validate our approaches. Forebrain interneurons are a
particularly robust context to develop these methods because the circuits interneurons
contribute to during development are both dynamic and transient. This makes them a
particularly attractive target for exploring longitudinal gene expression (Aim 1). This will
be achieved using a modification of the DamID method, which we have redesigned to
make inducible at particular developmental timepoints. Moreover, the diversity within this
population is considerable, making them an ideal target for exploring methods to
efficiently target subpopulations without the need for transgenic tools (Aim 2). In this aim
we will leverage transcriptome data sets, including data produced in Aim1. Utilizing a
computational program identify enhancer elements for mediating directed gene
expression in rAAVs. Viruses produced in this aim will be validated for use in mice and
less genetically amenable species, including non-human primates.
