Abstract

It is becoming increasingly clear that single cortical neurons encode complex and behaviorally relevant signals, but efficient means to study gene functions in small networks and single neurons in vivo are still lacking. Here, we establish a method for genetic manipulation and subsequent phenotypic analysis of individual cortical neurons in vivo . First, lentiviral vectors are used for neuron-specific gene delivery from α-calcium/calmodulin-dependent protein kinase II or Synapsin I promoters, optionally in combination with gene knockdown by means of U6 promoter-driven expression of short-interfering RNAs. Second, the phenotypic analysis at the level of single cortical cells is carried out by using two-photon microscopy-based techniques: high-resolution two-photon time-lapse imaging is used to monitor structural dynamics of dendritic spines and axonal projections, whereas cellular response properties are analyzed electrophysiologically by two-photon microscopydirected whole-cell recordings. This approach is ideally suited for analysis of gene functions in individual neurons in the intact brain.

  • Conventionally used AAV backbones with a 1.3 kb CaMKIIα promoter, WPRE, and human growth hormone polyadenylation signal have a capacity of 2.4 kb.

    “Conventionally used AAV backbones which include a commonly used neuronal expression cassette composed of 1.3 kb CaMKIIα promoter (which shows comparable expression efficiency with 0.4 kb CaMKIIα promoter [10] used in CWB), WPRE, and human growth hormone polyadenylation signal [23-25] has a capacity of 2.4 kb.”

    From Optimization of AAV expression cassettes to improve packaging capacity and transgene expression in neurons (2014) · cites this paper as [10]

    Table 1 (Methods, p. 2) identifies a 1.3-kb α-CaMKII promoter used in this paper’s lentiviral vectors. The Discussion (p. 6) gives an approximately 10-kb limit for a lentiviral promoter-and-gene cassette, not a 2.4-kb capacity for an AAV backbone. The cited passages do not establish the claimed AAV cassette with WPRE and a human growth hormone polyadenylation signal. (LLM, conf=0.89)

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.
