Abstract

Chondroitin sulfate (CS) plays critical roles in central nervous system development and regeneration, and individual modifications of CS form a "sulfation code" that regulates growth factor signaling or neuronal growth. Although we have shown that CS-E polysaccharide, but not CS-A or -C polysaccharide, has an inherent ability to promote neurite outgrowth toward primary neurons, its molecular mechanism remains elusive. Here, we show the involvement of a plasma membrane-tethered cell adhesion molecule, contactin-1 (CNTN-1), in CS-E-mediated neurite extension in a mouse neuroblastoma cell line and primary hippocampal neurons. CS-E, but not CS-A, -C, or heparan sulfate, engaged CNTN-1 with significant affinity and induced intracellular signaling downstream of CNTN-1, indicating that CS-E is a selective ligand for a potential CS receptor, CNTN-1, leading to neurite outgrowth. Our data provide the first evidence that biological functions of CS are exerted through the CS receptor-mediated signaling pathway(s).

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.
