Abstract

OBJECTIVES: Chemokines are implicated in many diseases of the central nervous system (CNS). Although their primary role is to induce inflammation through the recruitment of leukocytes by their chemotactic activity, they may also have direct effects on neuronal cells. We evaluated the expression of CXCR1 and CXCR2 and investigated the effect of CXCR2 activation by the agonist MIP-2 (CXCL2) on primary cultured motor neurons. To specifically assess the role of CXCR2 in the neurotoxicity induced by MIP-2, we used the CXCR1/2 inhibitor reparixin and studied the effect of the chemokine on motor neuron cultures from CXCR2-deficient mice. METHODS: Primary motor neurons prepared from rat or mouse embryos were treated with MIP-2 and reparixin. Motor neuron viability and receptor expression were assessed by immunocytochemical techniques. RESULTS: Rat primary motor neurons expressed CXCR2 receptors and recombinant rat MIP-2 induced dose-dependent neurotoxicity. This neurotoxicity was counteracted by reparixin, a specific CXCR1/2 inhibitor, and was not observed in motor neurons from CXCR2-deficient mice. CONCLUSIONS: CXCR2 activation might directly contribute to motor neuron degeneration. Thus, chemokines acting on CXCR2, including IL-8, may have direct pathogenic effects in CNS diseases, independent of the induction of leukocyte migration.

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.
