Specific and behaviorally consequential astrocyte G q GPCR signaling attenuation in vivo with iβARK

ABSTRACT: The Khakh laboratory used astrocyte selective AAVs expressing Rpl22-HA along with bARK for attenuating Gq pathway signaling in the dorsal striatum. In the control group, bARK(D110A), which is a mutated control of bARK was expressed instead of bARK. The mouse striatum expressing either bARK or bARK(D110A) was subjected to RNA-seq in order to compare striatal astrocyte transcriptomes with and without Gq-GPCR signaling attenuation.

Astrocyte Gi signaling activation in the striatum

Project description:The Khakh laboratory used astrocyte selective AAVs expressing Rpl22-HA and hM4Di, a Gi DREADD, in the striatum. Mice recieved either 1 mg/kg CNO or vehicle to compare striatal astrocyte transcriptomes with and without Gi-GPCR signaling activation.

Astrocyte molecular signatures during Huntington’s disease progression and following huntingtin lowering with zinc finger protein transcriptional repressors

Project description:The Khakh laboratory used gfaABC1D-RiboTag AAVs to purify and sequence astrocyte actively translated mRNAs from Huntington's disease mouse models at several stages of the disease. Two weeks after AAV injection, striata were homogenized and RNA was purified from (i) cleared lysate as the input and control, and (ii) astrocyte-specific ribosome-associated RNA precipitated via a hemagglutinin (HA) tag. R6/2 mice are a fast developing model of Huntington's disease. Striatal cells show mutant HTT inclusions as early as 4 weeks of age. These mice show the first motor and cognitive symptoms around that age, but they become more evident around 8 week old and progressively impair until the mouse death that occurs around 13 weeks of age. Motor symptoms include increased paw clasping and grooming, impaired grip strength and rotarod performance, gait alterations, involuntary movements, etc. Cognitive impairment includes defects in learning and memory. NCAR mice are the healthy "non-carrier" controls for R6/2. They don't have unexpected phenotypes.

Enhancer-AAVs allow genetic access to diverse populations of astrocytes and oligodendrocytes across species

Project description:Proper brain function requires the assembly and function of diverse populations of neurons and glia. Single cell gene expression studies have mostly focused on characterization of neuronal cell diversity; however, recent studies have revealed substantial diversity of glial cells, particularly astrocytes. To better understand glial cell types and their roles in neurobiology, we built a new suite of adeno-associated viral (AAV)-based genetic tools to enable genetic access to astrocytes and oligodendrocytes. These oligodendrocyte and astrocyte enhancer-AAVs were highly specific, showed variable expression levels, and our astrocyte enhancer-AAVs showed multiple distinct expression patterns that reflected the spatial distribution of astrocyte subtypes. To provide the best glial-specific functional tools, several enhancer-AAVs were: optimized for higher expression levels, shown to be functional and specific in rat and macaque, shown to maintain specific activity in epilepsy where traditional promoters changed activity, and used to drive functional transgenes in astrocytes including Cre recombinase and acetylcholine-responsive sensor iAChSnFR. The astrocyte-specific iAChSnFR revealed a clear reward-dependent acetylcholine response in astrocytes of the nucleus accumbens during reinforcement learning. Together, this collection of glial enhancer-AAVs will enable characterization of astrocyte and oligodendrocyte populations and their roles across species, disease states, and behavioral epochs.

New transgenic mouse lines for selectively targeting astrocytes and for studying calcium signals in astrocyte processes in situ and in vivo

Project description:The Khakh laboratory developed and characterized a new Aldh1l1-Cre/ERT2 transgenic mouse line to selectively target astrocytes in vivo. Crosses with RiboTag mice allowed sequencing of actively translated mRNAs and analyses of the cortical astrocyte transcriptome from adults.

Striatal astrocyte Crym KO transcriptome

Project description:We overexpressed Rpl22-HA in astrocytes of the mouse striatum in both wild type (WT) mice and in Crym KO mice at five months of age. Crym has been shown to be expressed predominantly in striatum and is highly expressed in astrocytes, however the function of this protein in astrocytes is unknown.

Young and Aged Striatal Astrocyte MERFISH Panel

Project description:Given that the striatum is a large, multifunctional nucleus, we next aimed to understand where astrocyte subtypes exist in the striatum at a single-cell resolution using MERFISH. We reproducibly identified the seven astrocyte subtypes, some of which were dorsal (A1, A7), medial (A3, A6) or ventral dominant (A4).
