Abstract

Nicotinic acetylcholine receptors (nAChRs) contribute significantly to hippocampal function. α7-nAChRs are present in presynaptic sites in hippocampal neurons and may influence transmitter release, but the factors that determine their presynaptic localization are unknown. We report here that Wnt-7a, a ligand active in the canonical Wnt signaling pathway, induces dissociation of the adenomatous polyposis coli (APC) protein from the β-catenin cytoplasmic complex and the interaction of APC with α7-nAChRs in hippocampal neurons. Interestingly,Wnt-7a induces the relocalization of APC to membranes, clustering of APC in neurites, and coclustering of APC with different, presynaptic protein markers.Wnt-7a also increases the number and size of coclusters of α7-nAChRs and APC in presynaptic terminals. These short-term changes in α7-nAChRs occur in the few minutes after ligand exposure and involve translocation to the plasma membrane without affecting total receptor levels. Longer-term exposure to Wnt-7a increases nAChR α7 subunit levels in an APC-independent manner and increases clusters of α7-nAChRs in neurites via an APC-dependent process. Together, these results demonstrate that stimulation through the canonical Wnt pathway regulates the presynaptic localization of APC and α7-nAChRs with APC serving as an intermediary in the α7-nAChR relocalization process. Modulation by Wnt signaling may be essential for α7-nAChR expression and function in synapses.

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

  • Wnt2 and other proteins usually linked to neural development might also play significant roles in regulating neuronal function after critical periods.

    “nonetheless, Wnt2 and other proteins traditionally associated with neural development may have important roles in post-critical period regulation of neuronal function (Farias et al., 2007; Moon et al., 2004; Wayman et al., 2006).”

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.
