Astrocyte‐released cytokines induce ramification and outward K+ channel expression in microglia via distinct signalling pathways
Abstract
Differentiation of microglial cells is characterized by transformation from ameboid into ramified cell shape and up-regulation of K+ channels. The processes of microglial differentiation are controlled by astrocytic factors. The mechanisms by which astrocytes cause developmental changes in morphological and electrophysiological properties of microglia have remained unclear. We show here that the cytokines transforming growth factor-beta (TGF-beta), macrophage colony-stimulating factor (M-CSF) and granulocyte/macrophage colony-stimulating factor (GM-CSF) are released by astrocytes at concentrations sufficient to induce ramification and up-regulation of delayed rectifier (DR) K+ channels in microglia. Transformation from ameboid into ramified morphology induced in microglia by exposure to astrocyte-conditioned medium (ACM) was inhibited by neutralizing antibodies against TGF-beta, M-CSF or GM-CSF, whilst ACM-induced DR channel expression was exclusively inhibited by antibodies against TGF-beta. Although both ramification and DR channel up-regulation occurred simultaneously, DR channel blockade by charybdotoxin failed to inhibit microglial ramification. The ACM-induced ramification of microglia was inhibited by the tyrosine kinase inhibitor genistein, whereas DR channel up-regulation did not occur in the presence of the serine/threonine kinase inhibitor H7. Our data suggest that astrocytes modulate processes of microglial differentiation in parallel but via distinct signalling pathways.

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.
