DESCRIPTION

The Genetic Tools Atlas (GTA) is a searchable catalog of enhancer-
adeno-associated viruses (AAVs) that have been developed and tested at
the Allen Institute for Brain Science. We present a suite of enhancer
AAVs that can provide access to specific cell types when delivered to
the whole brain. Multiple epigenomic  and transcriptomic datasets were
interrogated to reveal candidate enhancers that are selectively
accessible in particular cell populations. Enhancer AAVs were
constructed and screened for desirable expression and a sizeable
subset of enhancer AAVs were subjected to further characterization by
single cell transcriptomics and/or brain-wide expression imaging in
mouse. In the GTA, we present a large toolkit for selective gene
expression in cell types of interest.

Data Collection: GTA EPI

Epifluorescence datasets consist of sagittal sections, imaged using an
epifluorescence microscope. In most experiments, enhancers are used to
drive expression of SYFP2 (green) with a nuclear DAPI (blue) and
propidium iodide (PI; red) counterstain. In experiments where the
enhancer drives expression of a recombinase, signal will most offer
appear in tdTomato (red) and the PI counterstain will be omitted.

Species: mouse

Data Collection: GTA STPT

Serial Two-Photon Tomography datasets are produced by serial
sectioning of an intact brain at 100 μm along the coronal plane,
followed by 2-photon imaging of the exposed surface. The resulting
dataset enable qualitative evaluation of the main regions/populations
labeled by each enhancer AAV, across the entire brain.

Species: mouse
Specimen Type: whole brain

Data Collection: GTA sc/snRNA-seq

Single Cell/Single Nucleus RNA Sequencing is used to determine the
molecular identity of cells labeled by a specific enhancer AAV. In
this approach, a region of interest (ROI) is dissected following
vector delivery, and the tissue is dissociated for isolation of
individual labeled cells/nuclei. RNA Sequencing results from each cell
is then mapped to the taxonomy most relevant to the dissected ROI, and
the degree of enrichment for the most highly represented population
can be determined.
