Abstract

Cholinergic interneurons (ChIs) in the nucleus accumbens (NAc) have been implicated in drug addiction, reward, and mood disorders. However, the physiological role of ChIs in depression has not been characterized. Here, we show that the tonic firing rate of ChIs in NAc shell is reduced in chronic stress mouse models and in a genetic mouse model of depression. Chemogenetic inhibition of NAc ChIs renders naive mice susceptible to stress, whereas enhancement of ChI activity reverses depressive phenotypes. As a component of the molecular mechanism, we found that the expression and function of the hyperpolarization-activated cyclic nucleotide-gated channel 2 (HCN2) are decreased in ChIs of NAc shell in depressed mice. Overexpression of HCN2 channels in ChIs enhances cell activity and is sufficient to rescue depressive phenotypes. These data suggest that enhancement of HCN2 channel activity in NAc ChIs is a feasible approach for the development of a new class of antidepressants.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • CSDS-induced changes in the activity of NAc cholinergic interneurons contribute to social behavior deficits, perhaps via regulation of local DA release or excitatory synaptic transmission.

    “CSDS-induced changes in the activity of NAc cholinergic interneurons also appears to contribute to the social behavior deficits [163], perhaps via regulation of local DA release [164] or excitatory synaptic transmission [165].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
