Abstract

After the partial denervation or paralysis of a muscle, the remaining motor axon terminals may sprout fine, neuritic processes (terminal sprouts) which escape the endplate region of the neuromuscular junction. We previously identified a muscle-derived, protein antigen of 56,000 daltons (56 kD) which plays a necessary role in terminal sprouting. A panel of monoclonal antibodies have been produced against the 56-kD antigen, some of which also partially suppress motor axon terminal sprouting. These monoclonal antibodies define at least two different epitopes upon the surface of the antigen, one of which is necessary for it to effect its biological role in vivo.

  • NLK may support survival of sensory and spinal neurons and stimulate axonal growth.

    “may support survival of sensory and spinal neurons and stimulate axonal growth [10–13]”

    From Cerebrospinal fluid levels of the neurotrophic factor neuroleukin are increased in early Alzheimer’s disease, but not in cerebral amyloid angiopathy (2021) · cites this paper as [10]

    The discussion (page not identified in our copy) associates the 56-kD antigen with spinal-neuron survival activity in culture, and reports that antibodies against it suppress motor-axon terminal sprouting. It does not identify the antigen as NLK or report that it supports sensory-neuron survival, so those parts of the claim are not established by this paper. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • In the extracellular space, NLK supports neuronal survival and stimulates axonal growth.

    “In the extracellular space NLK supports neuronal survival and stimulates axonal growth [10–13]”

    From Cerebrospinal fluid levels of the neurotrophic factor neuroleukin are increased in early Alzheimer’s disease, but not in cerebral amyloid angiopathy (2021) · cites this paper as [10]

    The Discussion (p. 2271) associates the soluble, muscle-derived 56-kD antigen with spinal-neuron survival activity in preliminary culture results and finds it necessary for motor-axon terminal sprouting. It does not identify the antigen as NLK or establish that it independently stimulates axonal growth; the authors explicitly leave open whether it is a sprouting factor or a necessary co-factor. (LLM, conf=0.85)

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.
