Abstract

Neuron-type specific gene batteries define the morphological and functional diversity of cell types in the nervous system. Here, we discuss the composition of neuron-type specific gene batteries and illustrate gene regulatory strategies which determine the unique gene expression profiles and molecular composition of individual neuronal cell types from C. elegans to higher vertebrates. Based on principles learned from prokaryotic gene regulation, we argue that neuronal terminal gene batteries are functionally grouped into parallel-acting 'regulons'. The theoretical concepts discussed here provide testable hypotheses for future experimental analysis of the exact gene-regulatory mechanisms employed in the generation of neuronal diversity and identity.

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

  • Once mature, comparable positive feedback can act within single cells to keep different neuronal phenotypes sharply distinct.

    “In the mature state, similar positive feedback loops can operate cell autonomously to enforce sharp separation between diverse neuronal phenotypes (Hobert et al., 2010).”
  • The identity and physiological state of neuron types are largely determined by their patterns of gene expression.

    “To a large extent, the identity and physiological state of neuron types are determined by their patterns of gene expression (Nelson et al., 2006, Hobert et al., 2010).”

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.
