Biochemical Computation for Spine Structural Plasticity

Open access
Nishiyama, Jun, Yasuda, Ryohei·2015·Neuron

Abstract

The structural plasticity of dendritic spines is considered to be essential for various forms of synaptic plasticity, learning, and memory. The process is mediated by a complex signaling network consisting of numerous species of molecules. Furthermore, the spatiotemporal dynamics of the biochemical signaling are regulated in a complicated manner because of geometrical restrictions from the unique morphology of the dendritic branches and spines. Recent advances in optical techniques have enabled the exploration of the spatiotemporal aspects of the signal regulations in spines and dendrites and have provided many insights into the principle of the biochemical computation that underlies spine structural plasticity.

  • There is compelling evidence that CaMKII, via phosphorylation, initiates a series of actin-based cytoskeletal rearrangements in the spine.

    “Indeed, there is compelling evidence that CaMKII, via phosphorylation, initiates a series of actin-based cytoskeletal rearrangements in the spine (32, 312–314).”

    From Synaptic memory and CaMKII (2023) · cites this paper as [313]

    The ‘Calcium sensing’ and ‘Regulation of actin cytoskeleton’ sections describe CaMKII as an early spine-specific signal in LTP and place actin-remodeling pathways downstream of it. They do not establish the claim’s specific mechanism that CaMKII initiates those rearrangements via phosphorylation. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • The strongest case for the requirement of downstream CaMKII targets in sLTP, and likely LTP, is the actin cytoskeleton.

    “In summary, perhaps the strongest case for the requirement of downstream CaMKII targets in sLTP, and likely LTP, is the actin cytoskeleton (30, 313, 321)”

    From Synaptic memory and CaMKII (2023) · cites this paper as [313]

  • The Rho GTPases Cdc42 and RhoA are required for LTP and sLTP.

    “and that the Rho GTPases Cdc42 and RhoA are required for LTP and sLTP (312, 313).”

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.
