( B) Adora1 expression by astrocytes (circles), oligodendrocytes (ovals), and microglia (triangles) in A1 and MG. Background shading in A1 layers represents relative density of VGluT2/A 1R TC inputs from MG (Hackett et al., 2016). Line thickness corresponds to projection strength. Arrows summarize thalamocortical (TC), corticocortical (CC), corticothalamic (CT), and corticotectal (Ct) projections of VGluT1/A 1R and VGluT2/A 1R containing neurons in A1 and MG.

Strategies to target Adora1 in specific cell types can be developed from the data generated here. Selective expression by neuronal and glial subpopulations suggests that experimental manipulations of A 1 R-adenosine signaling could impact several cell types, depending on their location. The collective findings imply that A 1 R-mediated signaling broadly extends to all subdivisions of auditory cortex and MG. In MG, Adora1 was expressed by glutamatergic neurons in all divisions, and subpopulations of all glial classes. Subpopulations of GABAergic neurons, astrocytes, oligodendrocytes, and microglia expressed lower levels of Adora1. In A1, Adora1 transcripts were concentrated in 元/4 and L6 of glutamatergic neurons. To advance understanding of the circuitry, in situ hybridization was used to localize neuronal and glial cell types in the auditory forebrain that express A 1 R transcripts (Adora1), based on co-expression with cell-specific markers for neuronal and glial subtypes. Interfering with adenosine signaling in primary auditory cortex (A1) does not contribute to these forms of plasticity, suggesting regional differences in the roles of A 1 R-mediated adenosine signaling in the forebrain. In the auditory forebrain, restriction of A 1 R-adenosine signaling in medial geniculate (MG) neurons is sufficient to extend LTP, LTD, and tonotopic map plasticity in adult mice for months beyond the critical period.
In thalamocortical (TC) projections to sensory cortex, adenosine functions as a negative regulator of glutamate release via activation of the presynaptic adenosine A1 receptor (A 1 R). Additional parking is available at the 25th Avenue Garage (requires Zone 3 permit), and metered parking (2-hour limit) along 24th Avenue South.In the brain, purines such as ATP and adenosine can function as neurotransmitters and co-transmitters, or serve as signals in neuron-glial interactions. Once you park, you will need to come inside the building and get a permit from the front desk to display inside your car.
